Poor management of dump-sites creates significant risks to environment and human health. Thus, sanitary landfills are required to be more effective to minimize the impacts of waste disposal. This research assesses the environmental economic evaluation focused on the economically efficiency of Malaysian sanitary landfills. Two landfills were selected based on their different operation. Landfill A incurred RM 128 million (USD 41.8 million) as the total cost within 20 operational period. Thus, it is estimated that the cost may be covered within 15 operational years. On the other hand, the total costs for Landfill B are estimated at RM 198 million (USD 64.8 million) with RM 245 million (USD 80.2 million) are expected to be obtained as profit within eight operational years. Landfill B has high initial costs of design and construction. However, the costs are covered within the first five years. This is because Landfill B introduces a new green technology namely landfill-gas power generator. This indicates that, Landfill B has stronger market competition ability as compared to Landfill A. It can be concluded that the implementation of green technology namely landfill gas harvesting system has higher impact to improve the economic value of a landfill thus making it more economical and environmentally sustainable.

Under the newly implemented waste management policy in European Union countries, sanitary landfilling constitutes the fourth and the least preferred of the alternative management options for the disposal of solid urban wastes. Landfills generate emissions over long periods, often longer than a lifetime. The longest lasting emission is leachate: leachate production and management is now recognized as one of the greatest problems associated with the environmentally sound operation of sanitary landfills. These liquid wastes can cause considerable pollution problems by contacting the surrounding soil, ground or surface waters and, are therefore considered major pollution hazards unless precautionary measures are implemented. Landfill leachate characterization is a critical factor in establishing a corresponding effective management strategy or treatment process. This paper summarizes leachate quality indicators, and investigates the temporal variation of leachate quality from municipal solid waste. The toxicity of leachates from the municipal solid waste landfill "Vinca" in Belgrade, the capital of Serbia, was characterized using toxicity characteristics leaching procedures (TCLP). The "Vinca" landfill was established in 1978 as one of several municipal landfills. Since the 1990-ies the "Vinca" landfill has been the only operating landfill servicing the Belgrade Metropolitan area, the biggest city in Serbia, with 1,576,124 inhabitants in the larger-city area, and 1,273,651 inhabitants in the inner-city area. The total average amount of solid wastes deposited in the landfill is estimated to be 1100 tons/day. The landfill site is not lined and the tributary flows through the centre of the site-in some places directly under the mass of refuse. No consideration has been given to the protection of ground waters, surface runoff or drainage. Local authorities plan to expand the landfill by 0.4 km2 to a total of 1.3 km Chemical analysis was performed on the samples and the temporal variation of several parameters was monitored including pH, COD, chlorides, sulfates, nitrates, ammonia nitrogen, hardness, and heavy metals. The COD and pH were related to the biological activity within the landfill and the results indicated differences between the samples due to waste age. The concentrations of heavy metals, sulfates, nitrates, chlorides and ammonia nitrogen in the leachate were low, indicating their initially low amount in landfilled waste or their flushing with moisture contributing to a reduction in their concentrations.

The aim of this study is to comprehensively assess the need for Sanitary landfills in Edo state for management of waste, control of pollution for sustainable manufacturing system using concurrent triangulation design. The concurrent triangulation design is in two phases, Phase 1 using quantitative analysis, descriptive statistics while phase 2 used the qualitative analysis using thematic selection. Final results collected from the merger of results from phase 1 and phase 2 showed the Regression analysis results had a T-test value of -0.4615 at P value significant of 0.000 obtained for Sanitary landfill in the model and was less than 5% level of significance indicating that there is a significant relationship between Sanitary landfilling and pollution control. The Durbin Watson result of 1.955 showed that the model is reliable with absence of serial auto correlation. A coefficient of - 0.346 showed that 1% increase in sanitary landfilling activities results in 34.6% decrease in environmental pollution. Hence Sanitary landfilling for waste management has proved to sustain manufacturing system, control environmental pollution and reduce waste.

Abstract Biological processes are known to reduce the organic fraction of municipal solid waste, but current landfilling practices have not been altered to reflect this knowledge. The advantages of enhancing degradation of solid waste are as follows: reduced period of leachate treatment, increased methane production, expedited landfill site reclamation through stabilized waste mining, and accelerated subsidence permitting recovery of valuable landfill air space. The techniques that can be used to enhance biological degradation include leachate recirculation, addition of nutrients, shredding, sludge addition, lift design, temperature and moisture content management. Manipulation of these variables promotes a more conducive environment for microbial activity. Research on landfill management strategies through laboratory and full-scale studies has shown the validity of applying the enhancement techniques with regards to reducing leachate strength and increasing methane production. These practices focus on the use of landfills as bioreactors, which enables long-term flexibility and assures compliance with future regulations and discharge standards.

Waste management (WM) is a demanding undertaking in all countries, with important implications for human health, environmental preservation, sustainability and circular economy. The method of sanitary landfilling for final disposal of waste remains a generally accepted and used method but the available scientific evidence on the waste-related environmental and health effects is not conclusive. Comparative studies of various WM methods (landfilling, incineration, composting etc.) show that among the municipal solid waste (MSW) treatment and disposal technological options, sanitary landfilling or open dumping is popular in most countries because of the relative low cost and low-technical requirement. The European Union (EU) Directive on waste landfills has introduced specific goals for reducing the volume of disposed waste and very strict requirements for landfilling and landfill sites. Evaluation of the impact of landfills on the environment is a crucial topic in the literature and has received increased attention recently, given growing environmental concerns. The main goal of this survey was to conduct a comprehensive assessment of possible impacts of MSW landfills on the environment. The main conclusion of the overall assessment of the literature is that the disposal of MSW in landfills entails a number of environmental risks but with respect to the current situation and rich style of living adopted in industrially developed countries, the idea of WM systems functioning without landfilling—at least in the foreseeable future within one generation—seems to be somewhat unreal. The results also provided important information of landfills as a source of environmental risk. Results of this research may have an important impact on landfill management and the disposal of waste. From the literature review, it is evident that even if high levels of waste avoidance, reuse and recycling are achieved, some waste materials will always need to be forwarded for disposal.

Extensive non-engineered landfilling practice in developing countries has raised environmental concerns, but operating a sanitary landfill appears infeasible due to financial incapability. This study aims to determine the feasibility of a sanitary landfill project by including its environmental values into the project appraisal while simultaneously applying three policy-relevant methods—non-market valuation, benefits transfer, and cost-benefit analysis—in two study areas in Peninsular Malaysia. The non-market valuation study used choice modeling, a questionnaire-based technique, to elicit willingness to pay among 624 households toward the environmental attributes of the sanitary landfill. Their responses resulted in the monetary values of the environmental attributes by referring to implicit prices of leachate discharge, bad odor, disease vector and view. The implicit prices of bad odor (RM2.29 per month) and view (RM3.59 per month) in the two study areas were transferable and used as a proxy of additional solid waste disposal payment in environmental cost-benefit analysis. Positive net present value offers empirical evidence of the feasibility of the sanitary landfill project. The findings show that the inclusion of environmental values in project appraisals increases the chances of implementing sanitary landfills, providing a new approach to address the environmental concerns in developing countries. Future research should consider the external costs along with the external benefits to allow for a comprehensive comparison between environmental values in environmental cost-benefit analysis.

Wastes from landfills originate from many spheres of life. These are produces as a result of human activities either domestically or industrially. The global plastic production increased over years due to the vast applications of plastics in many sectors. The continuous demand of plastics caused the plastic wastes accumulation in the landfill consumed a lot of spaces that contributed to the environmental. In addition, economic growth and development also increased our demand and dependency on plastics which leads to its accumulation in landfills imposing risk on human health, animals and cause environmental pollution problems such as ground water contamination, sanitary related issues, etc. The management and disposal of plastic waste have become a major concern, especially in developing cities. The idea of waste to energy recovery is one of the promising techniques used for managing the waste of plastic. Hence, this paper aims review at utilizing of plastic as an alternative fuel.

This study collected basic information and conducted waste composition surveys to identify the present management condition of construction and demolition waste (CDW) landfills in Hanoi of Vietnam and to characterize waste composition and grain size distribution of CDW dumped at landfills. Basic information on seven CDW landfills under operation or closed/abandoned was collected, and the waste composition and the grain size distributions of dumped CDW at two landfills were investigated. Results showed that only one landfill site is currently under operation in Hanoi. Sanitary conditions of investigated landfills were relatively good without dumping of hazardous waste. Illegal dumping of domestic waste from residents, however, could be observed more or less at all sites due to an unclear boundary between dumping and surrounding areas. To improve current management of CDW landfills, a suitable recording system of accepted/dumped CDW and technical support for site managers are required as well as the implementation plan for developing and renovating landfills. Based on the results of the waste composition survey, the major components of dumped CDW were “Concrete”, “Clay bricks”, and “Soil-like”, and the sum of these materials reached >80% of the total. Grain size distributions of “Concrete” ranged from 10–600 mm and of “Clay bricks” ranged from 10–300 mm. Technical recommendations to examine a potential availability of dumped “Concrete” and “Clay bricks” as a base material in road construction are summarized from the viewpoints of segregation from “Soil-like” and impurities, grading of “Concrete” and “Clay bricks”, mechanical properties and environmental safety, and economic feasibility. The findings in this study raise challenges and perspectives to establish sound CDW management and to promote sustainable development of CDW recycling in Vietnam.

The today's world faces a rapid increase of population and thus a growing amount of generated waste. Unsorted municipal waste is transported to landfills. The negative environmental impact of a landfill is related with generated odours, polluted leachate and waste itself. Most of present landfills do not meet minimal environmental and sanitary requirements, i e most of landfills do not have an installed leachate collection system. In Lithuania waste management is related with many problems. The municipal waste collection system is inefficient, and the equipment is outdated. Large amounts of recyclable waste materials mixed with other wastes are still disposed in landfills. Aiming to use anaerobic digestion technologies for organic waste and minimize their negative environmental impact, recyclables need to be separated. The paper gives information about experimental investigation with fruit, vegetable and meat waste humidified with addition of moisture to 75 %, 79 % and 85 %. The experiment lasted for 60 days, and the concentration of methane and oxygen as well as temperature changes in vessels were observed. The results showed that in 50 l containers of mixed waste set with moisture to 85 % higher amounts of methane were produced than in those humidified with less water.

Despite environmental regulations in Ecuador, particularly in the Province of Azuay, the solid waste final disposal management is still a socio-environmental problem, worsened by weak governance processes. The province has three sanitary landfills with almost expired service lives. The site selection was based on circumstantial reasons, which makes landfills more likely to cause environmental pollution and, therefore, have negative implications for public health. The largest landfill serves Cuenca and also leases service to other small cities. The remaining two are small and, accordingly, have limited technology and fewer resources. In this context, the main aim of this study is to evaluate the terrain of the province to find the most suitable area for landfill siting. A multi-criteria decision analysis, integrated with a geographical information system and analytical hierarchy process methodology, was conducted. Fourteen factors and seven constraints were simultaneously analysed, divided into technical, environmental, social, and economic categories; 15 of these criteria were from the Ecuadorian Unified Text of the Secondary Legislation of the Environmental Ministry. According to the results, 76.17% of the territory is not suitable for landfill implementation, and the unrestricted area represents the remaining 23.83%. The highest landfill suitability index (70–81%) is located in the south of the province in Santa Isabel, Oña, and Nabón cantons, which are dry and clay-rich areas.

The most important component of solid waste management is long-term safe and reliable disposal of solid waste in sanitary landfills. Leachate formed in landfills needs proper management. The biodegradable portion of waste is largely responsible for the production of leachate and landfill gas. This paper presents the outcome of the research on the water management of landfill in Nepal using a designed and built pilot scale field lysimeter model. The leachate production from the lysimeter as an effect of climatological factors is assessed. The Hydrologic Evaluation of Landfill Performance (HELP) model is used to compute estimates of water balances. Simulation of the model indicates that the evapotranspiration (ET) is nearly constant and do not follow the precipitation and percolation trend. Also the evapotranspiration component in this case, is not high. This may be due to the small surface area of lysimeter and larger portion of the leachate percolated before evaporation could take place. The model has been calibrated for the local situation with the limited observed data of leachate generation from the lysimeter. However the trend of leachate generation on HELP simulation and Actual Data seem to be similar during month of October to December season, but during June to September, the trend shows higher actual percolation rate compared to the model output. This may be due to the higher value of permeability of barrier soil (in the range of 10-5 cm/s), which should be generally in the range of 10-7 cm/s or lower. The rainy season during June to September may be another reason, when soil is wet most of the time. The annual data shows that percolation is about 81-84% of precipitation amount, whereas evapotranspiration is about 15-19%. The application of the model may be a valuable tool to determine strengths and weaknesses of designing and operating of landfills in developing countries like Nepal.

Open Dumping and inadequate landfill management and waste management have negative impacts on the community. Failure to manage waste in Metro City is not only due to technical weaknesses, lack of financial support, inefficient management agencies, and inappropriate systems can cause Emotional Mental Disorders (GME) as well as densely populated settlements, slums, poor ventilation, damaged house buildings, damp and moldy walls of houses, to the presence of pests around the house can cause anxiety to mental disorders. Researchers evaluated the presence of landfills in 23 Karang Rejo Metro cities, so that the existence of landfill can be in accordance with the prevailing rules. The research method used is qualitative, researchers decipher words in the opinion of respondents descriptively. In addition to interviews, to strengthen the data sought, researchers took pictures and made observations to the community with inter-community interactions, how people live environmental and social lives. Garbage disposal technology has developed, one of the development of the waste disposal method is the Sanitary Landfill method, with the Reusable Sanitary Landfill (RSL) model. The way the supply method works is that the garbage is stacked in a land, then the garbage can is compacted as a ground liner. Ground liners are coated with geomembranes, this layer that will withstand the pervasiveness of lindi into the soil and contaminate groundwater. On top of the geomembrane layer is another geotextile that serves to hold the dirt so that it does not mix with lindi water. The limitations of perspective in the study because the study lies in the small sample, it is suggested it is necessary to do more research by comparing some cases with different concepts.

This research focuses on providing a solution to rural sectors' problems regarding solid waste management and final disposal. It considered the Sanitary Landfill (SL) technical-environmental viability for rural communities in the north of Santa Elena-Ecuador. The objective is to propose a methodology for evaluating a sanitary landfill's technical-environmental viability, considering a Key Factors Matrix (KFM) for the possibility of its application in rural communities. The proposed methodology is based on: i) identification of preliminary and field data for assessment of the sector through the KFM, and ii) determination of the technical-environmental viability of an SL according to the aspects considered. The KFM allowed the Ayangue commune to be chosen for the location of the SL under certain precautions. Given this sector's tourist influence, solid waste accumulates 40 tons per day from the ninth year on. Therefore, it is recommended to bear in mind a possible restructuring of the SL, from a semi-mechanized system to a fully mechanized one.

This paper reviews the role of sanitary landfills in current and future waste management strategies based upon the principles and the goals established by the European Framework Directive on Waste (2008/98/EC). Specific reference is made to studies of our research group regarding new tools developed to evaluate leachate production, taking into account the different characteristics of municipal solid waste (MSW). Laboratory leaching tests and a methodology proposed to interpret the results are described and discussed, as well as tools developed to estimate landfill leachate production. Residual flows produced by mechanical-biological treatment (MBT) plants, mainly Solid Recovered Fuel (SRF) and Stabilized Organic Waste (SOW), incineration and composting plants are considered in particular. Experimental results showed that the most suitable end-uses or disposal options for the outputs of waste treatment plants are site-specific and should be defined on the basis of a detailed characterization. The application of the model developed to assess landfill leachate production showed a very good agreement with field data.

Recently, the problem of environmental safety through the formation of large volumes of waste has become of particular importance. Activities in the field of production and consumption waste management are one of the most environmentally hazardous and cause significant anthropogenic action due to the risk of adverse effects of hazardous chemical and biological compounds — the constituents of waste products for human health and environment. Any waste, especially in violation of the rules of handling may become environmentally hazardous at certain conditions. Objective. To determine the influence of solid household waste landfills in the Region of Kyiv on adjacent environmental objects (atmospheric air, soil, soil and surface waters). Methods. Sanitary chemical, organoleptic, physical and chemical. Results. The results of experimental studies of the environmental objects at the places of solid household waste landfills suggest the pollution of atmospheric air with formaldehyde, surface and ground waters, soils with hazardous chemical compounds — petroleum products, phenol, heavy metals, ammonium nitrogen, nitrates. Conclusion. Obtained experimental data indicate the discrepancy of the data of solid household waste landfills with regulatory documents regulating the arrangement and functioning of such landfills, and their operation takes place with violation of environmental requirements. Key words: solid household waste landfills, EU Directive, Ukrainian legislation, heavy metals.

As Malaysia is a fast-developing country, its prospects of sustainable energy generation are at the center of debate. Malaysian municipal solid waste (MSW) is projected to have a 3.3% increase in annual generation rate at the same time an increase of 3.3% for electricity demand. In Malaysia, most of the landfills are open dumpsite and 89% of the collected MSW end up in landfills. Furthermore, huge attention is being focused on converting MSW into energy due to the enormous amount of daily MSW being generated. Sanitary landfill to capture methane from waste landfill gas (LFG) and incineration in a combined heat and power plant (CHP) are common MSW-to-energy technologies in Malaysia. MSW in Malaysia contains 45% organic fraction thus landfill contributes as a potential LFG source. Waste-to-energy (WTE) technologies in treating MSW potentially provide an attractive economic investment since its feedstock (MSW) is collected almost for free. At present, there are considerable issues in WTE technologies although the technology employing MSW as feedstock are well established, for instance the fluctuation of MSW composition and the complexity in treatment facilities with its pollutant emissions. Thus, this study discusses various WTE technologies in Malaysia by considering the energy potentials from all existing incineration plants and landfill sites as an effective MSW management in Malaysia. Furthermore, to promote local innovation and technology development and to ensure successful long-term sustainable economic viability, social inclusiveness, and environmental sustainability in Malaysia, the four faculties of sustainable development namely technical, economic, environmental, and social issues affiliated with MSW-to-Energy technologies were compared and evaluated.

AbstractWaste becomes one of the crucial problems, even including cultural problems, because the impact will disrupt all aspects of life. Most landfills are operated using an open dumping system even though the landfill is designed with a sanitary landfill system. Therefore proper handling is needed to reduce the risks associated with waste problems. One of the waste handlings that can be done is with a sustainable waste management system, which is the concept of zero waste. This is in line with the efforts of the SDGs' target to state that the country as a whole can reduce waste generation through prevention, reduction, recycling, and reuse. This study uses a descriptive qualitative method with a technical approach to the analysis of literature studies in examining zero waste-based waste management systems through several case studies, namely the City of Canberra, South Korea, Sweden, Brazil, Japan, and Germany. The results showed that implementing the waste management system with the concept of zero waste required the collaboration of all parties not only stakeholders, and indirectly the cultural characteristics of the community played an important role to realize the concept of zero waste because of the need for high public awareness. And essentially all parties, both the government and the community want to reduce the amount of waste from both sources and landfills and improve the recycling system to create an ideal city. Keywords: Municipal Waste, Waste Management, Zero Waste AbstrakSampah menjadi salah satu permasalahan yang krusial bahkan termasuk masalah kultural karena dampak yang ditimbulkan akan mengganggu semua aspek kehidupan. Sebagian besar tempat pembuangan sampah dioperasikan dengan menggunakan sistem open dumping walaupun TPA tersebut didesain dengan sistem sanitary landfill. Oleh sebab itu diperlukan penanganan yang tepat untuk mengurangi resiko terkait masalah sampah. Salah satu penanganan sampah yang dapat dilakukan adalah dengan sistem pengolahan sampah berkelanjutan yaitu konsep zero waste. Hal ini sejalan dengan upaya target SDGs menyatakan bahwa negara secara menyeluruh mampu mengurangi timbulan sampah melalui pencegahan, pengurangan, daur ulang, dan pemakaian kembali. Penelitian ini menggunakan metode deskriptif kualitatif dengan pendekatan teknis analisis studi literatur dalam mengkaji sistem pengelolaan sampah berbasis zero waste melalui beberapa studi kasus yaitu Kota Canberra, Korea Selatan, Swedia, Brasil, Jepang, dan Jerman. Hasil penelitian menunjukkan bahwa untuk menerapkan sistem pegelolaan sampah dengan konsep zero waste diperlukan kerjasama semua pihak tidak hanya pemangku kepentingan, dan secara tidak langsung komitmen masyarakat berperan penting untuk mewujudkan konsep zero waste karena perlunya kesadaran masyarakat yang tinggi. Dan pada hakekatnya semua pihak baik pemerintah dan masyarakat menginginkan untuk mengurangi jumlah sampah baik dari sumber maupun TPA dan meningkatkan sistem daur ulang untuk mewujudkan kota yang ideal.Kata Kunci : Sampah Kota, Pengelolaan Sampah, Zero Waste

Toisapu Village Landfills in Ambon has been established since 2003 using open dumping system in processing the waste. These activity has caused negative externalities for the people living around the landfill. This paper aimed to analyze the factors that affected people's willingness to pay a higher levy for better waste management, the amount of the retribution to pay, and the closure of the operational costs through the analysis of willingness to pay (WTP) with four scenarios offered in the Baguala and Nusaniwe Regencies. The results showed that the factors affecting people's willingness to pay a higher retribution in the Baguala and Nusaniwe regencies were the level of education and the distance between their home and landfill. The highest average of WTP in Baguala regency of biogas scenario was Rp 24.250/ KK/ month, and the lowest in the incineration scenario was Rp 20 804/ KK /month. While in the Nusaniwe regency, the highest average of WTP obtained was Rp 21 228/ KK/ month in composting scenario, and the lowest was of Rp 18 220/ KK/ month in sanitary landfill scenario. The value of society WTP obtained was the value of retribution to pay, and this value could cover the operational costs required to implement the four scenarios of waste management offered.

This study investigated the management of biomedical pollutants in the Accra Metropolitan Area in Ghana, using a qualitative case study approach involving interviews, focus-group discussions, and observation techniques. A state of precariousness was found to characterize the management of biomedical pollutants in the study area, culminating in the magnification of risks to the environment and public health. There is neither a single sanitary landfill nor a properly functioning incineration system in the entire metropolis, and most of the healthcare facilities surveyed lack access to suitable treatment technologies. As a result, crude burning and indiscriminate dumping of infectious and toxic biomedical residues were found to be widespread. The crude burning of toxic biomedical pollutants was found to provide environmental pathways for carcinogenic substances. These include polynuclear aromatic hydrocarbons (PAHs), polychlorinated dibenzofurans (PCDFs), polychlorinated dibenzo-para-dioxins (PCDDs), polychlorinated biphenyls (PCBs), hydrogen, lead, mercury, cadmium, chlorobenzenes, particulate matter, and chlorophenols. The improper disposal of biomedical pollutants in open dumps and unsanitary landfills also carries a risk of providing environmental entry points for volatile organic compounds (VOCs), inorganic macrocomponents, heavy metals, and xenobiotic organic compounds.

Since the 1970s, federal and state regulations have dramatically changed the management of municipal solid waste in the Commonwealth of Virginia. Regulations required open dumps to be replaced by sanitary landfills with control technology to prevent environmental contamination. In contrast to local governments, private waste management companies had the financial resources to construct landfills with the necessary technology. Recently, companies have found that these expansive landfills could not survive financially on Virginia trash alone and began to import waste from other municipalities on the East Coast. This practice has led Virginia to become the second largest importer of municipal solid waste in the country. Waste importation has developed into a political and legal battle that has pitted the Commonwealth and grassroots organizations against the waste industry and its clients. Each stakeholder group makes a compelling argument as to why their position best protects local economies, Virginia's citizens, and the Commonwealth's natural resources. However, the Commerce Clause prevents states from enacting statutes that would interfere with interstate trade of waste. This article discusses the growth of the waste industry in Virginia and the perspectives of stakeholders involved with the importation debate. Without federal legislative action, the author concludes, there is no straightforward answer to the "problem" of waste importation in Virginia.

This work aimed to estimate the annual methane production from the municipal solid waste disposal sites in Pakistan. In this study, the Intergovernmental Panel on Climate Change (IPCC) default methodology was used to estimate theoretical methane formation potential of the waste disposal sites in major cities of Pakistan. The estimates of this study are based on the last population census conducted in the year 2017 and latest available data regarding the waste generation and management practices in the cities considered in the study. Results showed that 31.18 million tonnes of municipal solid waste (MSW) is generated annually. The top 10 major populated cities in Pakistan (with 20% share in country’s population) contributing 31% share in the total quantity of MSW generated in overall country. On average 50–60% of the MSW generated is collected and openly dumped at the designated waste disposal sites. After analyzing the data, we estimate that annually 12.8 MtCO2-eq of methane is emitted from the waste disposal sites in major cities considered in this study. The methane produced from the waste disposal sites can be sustainably utilized as a source of energy through transforming MSW disposal sites (open dumps) to sanitary landfills with methane capturing and utilization facilities. In the present scenario of waste management and methane formation potential, sanitary landfills would generate 62.35 MWh of electric power if 25% of the methane was recovered and utilized in power generation.

Ho Chi Minh City (HCMC) is a mega city with a total population of more than ten million. The quantity of solid waste generated has been increasing significantly over the past two decades, and the average generated solid waste was 1,164 tonnes/day in 1992 and 8,845 tonnes/day in 2017. Municipal solid waste (MSW) management has been considered as one of the most severe environmental problems as the quantity of solid waste has increased while infrastructure for collection and treatment is not sufficient. The paper focuses on evaluating challenges and suggesting opportunities for reducing the amount of waste disposal in landfills through interception and separation of the waste at source. After the waste separation, the biodegradable organic materials and recyclable materials from MSW can be collected for further use. Based on the current situation of MSW management, technologies such as composting, biogas recovery and electricity generation either from anaerobic digestion plants or sanitary landfills are appropriate. Incineration for high calorific value waste can be adopted for energy recovery. Effective recycling technologies to convert waste into valuable products seem to be a solution for approaching zero waste for MSW management in HCMC.

Introduction. The overall situation in the field of waste management in Ukraine is extremely difficult, which is explained by the lack of preventive resource conservation and environmental protection policies, as well as the lack of financing of measures aimed at eliminating the negative consequences resulting from the increasing generation of waste. In particular, due to insufficient financing of landfill contents: there are violations of the schedules of their sanitary cleaning, which leads to the formation of spontaneous landfills in the territories of residential development, especially in rural areas; there are cases of chaotic accumulation of waste that is not compacted and not filled with soil; most landfills and the surrounding area have a terrible look. The general state of waste in Ukraine highlights the urgency and seriousness of the problem of domestic and industrial waste management.
Aim and tasks. The purpose of the article is to substantiate the role and disclosure of the peculiarities of the transport and logistics component of waste management strategies in the context of implementing resource-saving and environmental policy in Ukraine.
Results. As a result of the research it is determined that the reform of the waste management system is necessary, which envisages solving of such key organizational, economic and managerial tasks in the context of realization of resource saving and environmental protection policy in Ukraine. The organizational and economic directions of waste management reform are: effective implementation of separate waste collection; construction of new landfills and waste treatment plants; information and institutional support for issues related to waste management; economically justified tariff formation ; stabilization of the finance industry through the introduction of a system of fines for violating legislation, in particular, on the separate collection of waste and the transfer of funds received to the development of the industry, investments provided by state guarantees on the return of capital invested by the investor.
Conclusions. At present the reform of the waste management system is necessary by means of solving a series of interrelated organizational, economic and managerial tasks in the context of implementation of resource conservation and environmental protection policy in Ukraine. In particular, it is about the need for financial stabilization of the industry, the expediency of strengthening regulatory instruments and, at the same time, motivational instruments, etc. Based on the analysis of the relationship between these objectives and the objectives of environmental policy, in particular in the field of transport and logistics, as well as the content and constituents of waste management strategies in Ukraine, it was concluded that there is a need for an integrated approach to determine the role and place of transport-logistic component.

Sanitary landfilling still is one of the most common management systems of solid urban wastes. The persistent environmental impact of landfills depends on leachate characteristics. The present study aimed at the characterisation of leachate from two landfill sites in the prefecture of Thessaloniki, Greece. Mavrorachi landfill stands in our study as a representative Greek active landfill site, that started operating in 2008. Tagarades landfill has stopped receiving waste from 2008 after 27 years of full operation. In this investigation, leachate samples were physico-chemically characterised so as to assess their pollution potential and their concentration in regard to the type and age of landfill. Elevated concentrations of inorganic and organic constituents were observed in the leachate composition. COD ranged from 2,490 mg/L to 19,700 mg/L, while the respective range for BOD was 390-14,850 mg/L during a 35-year period. The pH values of the leachate samples presented more moderate fluctuations between 7.3 and 8.5. In addition, the ammoniacal nitrogen content increased as landfill age increased, whereas heavy metals concentrations showed significant variations with a slight decreasing trend. The results presented in this paper proved that as time passed, the values of most parameters decreased as the biodegradable compounds are broken down while the refractory compounds resist to biodegradation. Thus, the age has a pronounced influence on the composition of leachate. This study also focused on quantifying the level of contamination that leachates can be potentially cause on a comparative basis by Leachate Pollution Index (LPI). LPI values showed that pollution load was declining but is still not negligible after 33 years.

Energy recovery potential of a mesophilic co-digester treating OFMSW and primary sludge at an integrated biomethanization plant was investigated based on feasibility study results. Since landfilling is still the main solid waste disposal method in Turkey, land scarcity will become one of the most important obstacles. Restrictions for biodegradable waste disposal to sanitary landfills in EU Landfill Directive and uncontrolled long-term contamination with gas emissions and leachate necessitate alternative management strategies due to rapid increase in MSW production. Moreover, since energy contribution from renewable resources will be required more in the future with increasing oil prices and dwindling supplies of conventional energy sources, the significance of biogas as a renewable fuel has been increased in the last decade. Results indicated that almost 93% of annual total cost can be recovered if 100% renewable energy subsidy is implemented. Besides, considering the potential revenue when replacing transport fuels, about 26 heavy good vehicles or 549 cars may be powered per year by the biogas produced from the proposed biomethanization plant (PE = 100,000; XPS= 61 g TS/PE⋅day;XSS-OFMSW=50 g TS/PE⋅day).

While developed countries use a variety of methods to convert municipal solid waste into various products such as energy, fertilizer, heat, and others, developing countries continue to struggle with municipal solid waste. Because of the various criteria to be considered, assessing these methods and determining which ones are best suited to the conditions of each country is a complicated task. The hybrid GREY-EDAS model was utilized in this study to evaluate waste treatment alternatives in Nigeria. The study employed seven distinct criteria relating to the environment, society, and cost, with the cost criterion being the most relevant. Subsequently, four waste treatment methods were evaluated: incineration, composting, sanitary landfills, and anerobic digestion. As a result, composting is proven to be the most effective. Sensitivity analysis was carried out by varying the weight of the criterion in seven distinct scenarios, and the model produced consistent findings.

With the escalated increase in municipal solid waste (MSW) generation in Malaysia reaching a shocking 38,000 ton/day in 2017, a sustainable waste management system is much desired. Nationwide, there are 176 landfills but only 8 are sanitary landfill with the rest are open dumpsites. In the campus of University of Malaya, UM Zero Waste Campaign (UM ZWC) was introduced in 2011 to start a long-term campaign to achieve an integrated and sustainable waste management model and ultimately a zero-waste campus. Since year 2015, UM ZWC is fully funded by Sustainability Science Research Cluster of UM (Susci) as one of the living labs of UM as well as by JPPHB under the RMK-11 budget. UM ZWC operating projects including in house composting center, food waste segregation scheme, research composting emission and waste characterization, anaerobic digestion (AD), used clothes collection program, wood waste separate collection, e-waste collection and drop-off recycling collection were initiated under the campaign. Since the inception of the project in 2011 until December 2017, almost over 620 tons of solid waste has been diverted from disposal in landfill with composting, AD, recycling, re-use and energy recovery. A roadmap of UM ZWC was drawn up in 2013, with a goal to achieve 60% landfill diversion by year 2040. In the next 5-10 years, UM ZWC plays a vital role to formalize the recycling collection in UM and further increase the organic waste recycling with green waste shredding and composting. Besides environmental benefits (pollution prevention and carbon emission reduction), UM ZWC brings various benefits such as academic research opportunities for UM, contribute in UM LCCF (Low carbon city framework) target and serve as platform to improve students soft skills and entrepreneur skill. Multi stakeholders participation, support form top management and industrial collaboration are the key factors that are able to drive the development of a sustainable waste management model in UM campus.

In Nigeria, the reliance on sanitary landfills is a common phenomenon in the disposal of waste materials. Lack of capital and appropriate technology for environmentally friendly waste management practices has left most places like Osogbo city in Nigeria to rely of landfills for solid waste disposal. And in most cases the landfills are not properly engineered and operated to accepted world standards. This project work assesses the effect of solid waste dumpsite on the ground water quality in Osogbo and Ede Metropolis. Eight (8) different samples were collected from wells located around the vicinity of dumpsite at Osogbo and Ede respectively. The analysis of physical, chemical and bacteriological parameters of the water samples collected shows that there are some level of contaminations on the ground water within the solid waste dumpsite and some of the samples were discovered to be acidic with PH ranges from 5.90-6.40 which rendered the sample unsafe for drinking and other domestic consumptions. Parameters like Iron, Manganese, Chromium, Copper, Zinc, are trace elementand were found in minute amounts concentration of less than 100mg/l in all the water samples, which possessed no hazard effect to the quality of groundwater. However, most of the water sample tested for bacteriological does not fall within WHO 2006 recommendations.Therefore, the need for environmental awareness through enlightenment campaigns on solid waste handling, controlling and monitoring techniques with proper groundwater exploration for proper analyses.

Abstract Municipal solid waste (MSW) management has emerged as one of the major environmental challenges globally. The consequences of inappropriate waste management are manifold and the trend would continue if immediate interventions are not taken for its reversion amid rapid urbanization and current consumption patterns of individuals. The concept of circular economy (CE) can contribute to a paradigm shift in the transformation of the traditional linear approach that does not favour reuse, recycle, recovery concept. Modern and proven waste management practices with collection systems, recycling facilities, sanitary landfills, and waste-to-energy (WtE) and nutrient recovery offer opportunities to improve urban environment through the valorization of waste and by-products in a CE. This study scrutinizes the existing literature on the assessment of circularity and helps to develop a unified circularity framework in the management of MSW in cities. Key aspects such as tools for measuring circularity, nexus and trade-offs, and conditions in promoting CE are discussed. Finally, this paper elucidates the need for circularity, including enablers and inhibitors for promoting circularity in the management of MSW with a case study in the city of Curitiba, Brazil.

The problem of establishing an effective solid waste management system is complex and still unresolved in Serbian municipalities, cities and settlements. Most landfills in Serbia do not meet basic sanitary standards and can often contain waste that is dangerous to human, plant and animal health, and waste that can be recycled is often dumped. The aim of this paper is to investigate the relationship between waste generation and private investments in waste management. Statistical method of multiple linear regression was used to examine the impact of three predictors - economic development, investments in waste management, and urban population, on the dependent variable - municipal solid waste generation. The results of the research reveal that investments in waste management in Serbia do not have an effect on the waste reduction because the financial resources for such investments are not adequately managed. There is a large number of scientific researches that have dealt with the analysis of the mentioned relationship, however, their number on the example of Serbia is rather scarce. The results of the research could be useful to the state administrations of the Republic of Serbia.

Increasing building construction raises concerns about construction and demolition (C&D) waste management. To assess this issue the building components, the collection schemes, their recycling and disposal should be investigated. In order to manage C&D wastes, paying attention to how this kind of wastes is disposed is imperative for their correct identification. Inattention, lack of organization and proper transport and sanitary disposal of construction and demolition waste lead to problems such as accumulation of construction waste in the streets. However, more than 90 percent of the potential for recycling and re-using as raw materials is provided. Environmental Protection Agency (EPA) has classified C&D wastes into three categories: non-dangerous waste, hazardous wastes and semi-hazardous wastes. Currently in Tehran, an average of about 50,000 tons per day of construction and demolition wastes are produced from which over 30,000 tons per day are dumped in landfills. According to this research more than 57% of these wastes are placed in the first category (non-dangerous waste) and have the potential for being recycled and reused. On the other hand, items that are placed in the second category shall be managed based on the existing laws. This article provides some management solutions including proposing methods for collecting and reusing construction waste in accordance with current market needs in Iran.

However, to our knowledge, there is still a limited number of academics whose research is focused on communicating environmental awareness to the public. While organizing communication about SDGs has faced challenges and new concerns, such as skepticism towards sustainability issues, rural and environmental issues seem to be the main agenda of development (Murphy, 2012). Thus, implementing the right communication methods is fundamental to delivering information to navigate the public's environmental orientation (Genç, 2017). Urban waste management in Indonesia still faces many obstacles, especially in terms of landfill existence. Only 60-70% of wastes can be transported and disposed in sanitary landfills (Badan Pusat Statistik, 2018). It creates so much waste, particularly related to food waste, over-packaging, and e-waste, all causing particular problems (Zaman and Lehmann, 2011). Limited natural resources force people to think hard about how to save existing natural resources.Teras Hijau Project (THP) was established out of a growing concern with the situation of the city of Bandung, Indonesia, especially in responding and improving themselves to be more sustainable. It is inspired by the Bio-Economic Initiative of European Union countries, which applies a "Circular Economy" as a basis of Regional Development.

The state and transformation of solid municipal waste management in Russia are considered against the background of economic and social changes associated with the current coronavirus pandemic. Increasing the volume and changing the structure of MSW in these conditions does not cancel, but increases the relevance of separate waste collection. It is shown that there are insufficient funds for subsidizing regions (on the example of the Republic of Khakassia) for financial support of regional operators in 2020 when companies stop, reduce their activities and reduce their solvency. The results of scientific studies of the properties of a new viral infection by microbiologists are incorporated into the assessment of the environmental and economic consequences of the burial of personal protective equipment used outside hospitals in a mixed composition at landfills. A model for determining the need of medical personnel for personal protective equipment in the treatment departments of patients with COVID-19 has been compiled. Savings due to disinfection by effective methods and subsequent reuse of personal protective equipment, amounting to 1/3 of the budget expenditures on the sanitary and epidemiological welfare of the population of Russia, have been calculated. The directions of further development of the state policy in the field of waste management during and after the end of the coronavirus pandemic have been proposed.

A disposição inadequada dos resíduos sólidos, atualmente, constitui um problema para a sociedade, tendo em vista os impactos ambientais que provoca, alterando a qualidade do solo, do ar e dos corpos aquáticos, e representando um risco para a saúde pública. Este artigo aborda aspectos do gerenciamento de resíduos sólidos na região Metropolitana II do Estado do Rio de Janeiro, discutindo ações desenvolvidas nesta área, da coleta à destinação final. Mais especificamente, analisa aspectos relacionados às classes de resíduos, resíduos sólidos gerados e triados, à situação atual da destinação final e ao gerenciamento de resíduos hospitalares, traçando-se, ao final, um panorama da situação do gerenciamento dos resíduos sólidos local. Durante os meses de janeiro a junho de 2008, foram realizadas visitas aos locais de destinação final dos resíduos sólidos - os aterros controlados e lixão, bem como entrevistas com técnicos responsáveis pelas ações de gerenciamento dos resíduos sólidos das Secretarias Municipais do Meio Ambiente, de Obras e de vigilância ambiental em saúde das Secretarias de Saúde, dos municípios da Região Metropolitana II, a saber: Niterói, São Gonçalo, Itaboraí, Maricá, Tanguá, Rio Bonito e Silva Jardim. A região Metropolitana II do Estado do Rio de Janeiro, embora composta por municípios com realidades bastante diferenciadas em termos de desenvolvimento social e econômico, possui grande parcela da população vivendo em condições precárias e sem acesso aos serviços públicos de saneamento, saúde e educação, vulnerável aos impactos ambientais. Verifica-se que a disposição final com o tratamento adequado dos resíduos sólidos constitui importante problema, não só para os governos e políticas públicas locais, mas também para as populações que convivem com os lixões. Destaca-se o importante papel dos catadores informais pelas cidades, muitos se organizando em pequenas cooperativas e grande parte operando em áreas urbanas onde o lixo é armazenado, aguardando coleta pública, ou, ainda, em alguns dos aterros controlados e no lixão da região. Há urgência de implantação de aterros sanitários ou aterro consorciado, desativando-se as áreas atuais de lixões e/ou aterros controlados, com ações de remediação de áreas degradadas, e, enfim, que se adotem soluções que dêem conta dessa importante parcela do saneamento básico, minimizando o impacto negativo dos solos e águas subterrâneas contaminados, visando-se a sustentabilidade da saúde e do ambiente, e o bem-estar das pessoas.

Abstract
The inadequate disposal of the solid residues, nowadays, is a social problem, concerning to suffered environmental impact, changing the quality of the soil, the air and of the water, being a risk to the public health. This article is about aspects of solid residues management at Metropolitana II region of the Rio de Janeiro state, discussing the development of actions on this area, from the collect to the final destination. More specifically, we analyze aspects related to the classes of residues, solid residues that were generated and discriminated, the actual situation of the final destination and to the management of the hospitals residues, constructing, at the end, a view of the local management of the solid residues. From January to June of 2008, visits were made at the locals of the final destination of the solid residues – the controlled landfills and the disposal waste areas, as well interviews with responsible technicians about actions of solid residues management of the environmental municipal secretaries, of Metropolitana II region: Niterói, São Gonçalo, Itaboraí, Maricá, Tanguá, Rio Bonito e Silva Jardim. The Metropolitana II region of the Rio de Janeiro state, although composed of very different realities between the municipals, concerning to economic and social development, has great portion of the population living in precarious conditions and without access to sanitary public services, health and education, vulnerable to the environmental impacts. We verify that the final disposal with adequate treatment of the solid residues constitute import problem, not only to the government and local public policies, but also to the population that live within waste. We mark the important function of the informal garbage pickers in the cities, many of them organized in small co-operative societies and a great part acting in urban areas where the trash is stored, waiting public collecting, or at some controlled landfill and disposal waste area. It's urgent the implementation of the sanitary landfills or partnership landfills, discarding the actual areas of waste disposal and/or controlled landfill, with remediation actions on the deteriorate areas, and, finally, solutions must be adopted to solve this important portion of the basic sanitation, minimizing the negative impact of the soil and contaminated subterranean water, aiming the health and the environmental support, and the well being of people.

Abstract Upflow anaerobic sludge blanket (UASB) reactors used in sewage treatment generate two by-products that can be reused: sludge and biogas. At the present time in Brazil, most of this resulting sludge is disposed of in sanitary landfills, while biogas is commonly burned off in low-efficiency flares. The aim of the present study was to use life cycle assessment to evaluate the environmental impacts from four different treatment and final destination scenarios for the main by-products of wastewater treatment plants. The baseline scenario, in which the sludge was sanitized using prolonged alkaline stabilization and, subsequently, directed toward agricultural applications and the biogas destroyed in open burners, had the most impact in the categories of global warming, terrestrial ecotoxicity, and human non-carcinogenic toxicity. The scenario in which heat resulting from biogas combustion is used to dry the sludge showed significant improvements over the baseline scenario in all the evaluated impact categories. The recovery of heat from biogas combustion decreased significantly the environmental impact associated with global warming. The combustion of dried sludge is another alternative to improve the sludge management. Despite the reduction of sludge volume to ash, there are environmental impacts inherent to ozone formation and terrestrial acidification.
