Full textAbstract:
Sanitary landfill remains the most common methodology for final treatment and disposal of municipal solid waste worldwide, the cost per tonne depends on its scale. The bigger the landfill, the cheaper the cost of treatment, so the consortium of municipalities is the solution to achieve an economic scale. However, the growth of waste production introduces pressure for adequate solutions and therefore has been increasing sanitary landfill site selection studies. This study proposes a methodology for siting sanitary landfills and optimising the transport of municipal solid waste for a locality in the state of São Paulo, Brazil. Environmental, social, and economic criteria were established. Their correlated attributes were categorised into suitability levels and weighted according to multiple decision analysis. The data were organised and mapped within a geographic information system. Considering sites where landfills are prohibited, two scenarios were generated. The Mixed-Integer Quadratic Programming mathematical model is used to minimise the costs of transporting municipal solid waste and operating sanitary landfills. In Scenario 1, the results indicated that 64% of the area was suitable as a potential sanitary landfill site, 9% of the area exhibited medium suitability, and 27% of the area was classified as restricted. In Scenario 2, the results indicated that 25% of the area was suitable as a potential sanitary landfill site, 4% of the area had medium suitability, and 71% of the area was classified as restricted. The optimal solutions for Scenario 1 and Scenario 2 enabled sites to be determined for five landfills and four landfills, respectively.

This study intends to identify influencing factors in the Implementation of Village Government in Sanitary Landfill Management in South Tungkal Village, North Pariaman District, Pariaman City. This research uses a semi-qualitative approach. A purposive sampling approach was used in this study to identify research informants. For data collection techniques, it is carried out with interviews and observations and documentation. For data analysis techniques using data reduction and data presentation and drawing conclusions. The results showed that there are influencing factors, namely: (1) Human resources that support the management of sanitary landfills. For human resources, the Environment Agency has 87 cleaning members consisting of drivers, stokars and 46 other members. (2) Second, a supportive commitment to the management of Sanitary Landfill. The form of commitment made provides budget and human resources to carry out the management of this Sanitary Landfill. (3) Third, community support and participation for sanitary landfill management. The community does not want to liberate land because the land has the status of customary land or customary land. (4) Fourth, the budget and tools are limited for the management of Sanitary Landfills. In Sanitary Landfill, the Environment Agency requires a budget for infrastructure and a human resources budget.

Full textAbstract:
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.

It is well known that the leachates from solid domestic waste sanitary landfills are heavily polluted with organic and inorganic substances. As they are of a potential danger for the environment, their uncontrolled seepage is avoided in the modern sanitary landfills by means of suitable insulation. This is mostly made of natural materials with a low filtration coefficient. The present paper considers the results of the filtration characteristics, studying natural clayey soil model liners. The leachate contaminants distribution from the sanitary landfill in Sofia (Suhodol) is traced out in different liner depths. The mechanism of pollutant attenuation in the liners is considered. It is found that a part of the leachate components (Fe, Mn, SO42−, PO43−) stays in clayey liners. Besides, as a result of pore colmatation the permeability of the liners is decreased. It is shown that soil monoliths with a proper thickness might serve as a sufficiently safe barrier against leachate filtration in adjacent aquifers. On the base of the results obtained the thickness of the clay liners in the solid domestic waste sanitary landfills could be optimized.

Abstract The majority of developing nations still utilize landfills as their primary method of disposing of municipal solid waste (MSW), and Indonesia is no exception to this technology. On the other hand, landfill contributes a significant fraction of plastic in the global environmental leakage from mismanaged landfill and open dumping site in Asian countries. Furthermore, Indonesia has a long history of landfill mismanagement and open dumping. The loss of plastic to the environment could lead to multisectoral impacts on the health, environment, and economy. In this paper, we analyze the current situation of landfill and the potential of plastic waste leakage from landfills to the environment using systematic review and metadata analysis using GIS in Indonesia. In addition, this study analyses potential plastic leakage based on the distance to the waterways, leachate treatment facility and landfill facility. Based on the analysis, only around 11% of the landfill were claimed as sanitary landfill, yet only 3% operated based on the sanitary landfill standard of Indonesia after the analysis. The controlled landfill is also implemented in Indonesia at around 52%, and open dumping is around 37% of total final disposal. Based on the GIS analysis, more than 20% of landfill in Indonesia are near the waterways, which increase the potential for plastic leakage. Policymakers can use the resulting study to identify and prioritise ways to stop the environmental leakage of plastics from landfills.

The objective of this research work is to determine the relationship between the operation of solid waste in intermunicipal sanitary landfills in the province of Cañete - Lima Region, 2018. In order to propose tools for its implementation and avoid the pollution that has been causing in the different districts of the province. The quantitative approach, non-experimental design, correlational type, was used through the survey technique and as an instrument the questionnaire, a population of 120 people, 20 per district of Cerro Azul, Nuevo Imperial and Quilmana. In the result there is no significant correlation between the sanitary landfill variable and solid waste, since the significance 0.05 is less than 0.59, therefore it is not significant and the correlation coefficient Pearson (r=,050) indicates that there is a moderate relationship between both variables. The moderate existence between the variables sanitary landfill and intermunicipal solid waste of the province of Cañete 2018 is concluded, it reflects the little interest in propitiating changes of behavior between authorities of the different districts focused on the investigation, provoking the vulnerability due to the lack of formal and sustainable sanitary landfills

Large quantities of solid municipal waste containing a variety of flammable substances, that are disposed of in sanitary and non-sanitary landfills and even illegal dump sites, usually entail a high risk of fire. The level of risk is increased by the presence of methane which is released by municipal waste decomposition. The number of landfill fires varies depending on the morphological composition of the waste, ignition sources, meteorological conditions, time of year, as well as fire protection measures. The paper describes the impact of flammable waste on landfill fires, as well as causes, frequency and procedures in preventing and extinguishing landfill fires.

Approximately 95% of urban solid waste worldwide is disposed of in landfills. About 14 million metric tonnes of this municipal solid waste are disposed of in landfills every year in Malaysia, illustrating the importance of landfills. Landfill leachate is a liquid that is generated when precipitation percolates through waste disposed of in a landfill. High concentrations of heavy metal(loid)s, organic matter that has been dissolved and/or suspended, and inorganic substances, including phosphorus, ammonium, and sulphate, are present in landfill leachate. Globally, there is an urgent need for efficient remediation strategies for leachate-metal-contaminated soils. The present study expatiates on the physicochemical conditions and heavy metal(loid)s’ concentrations present in leachate samples obtained from four landfills in Malaysia, namely, Air Hitam Sanitary Landfill, Jeram Sanitary landfill, Bukit Beruntung landfill, and Taman Beringin Landfill, and explores bioaugmentation for the remediation of leachate-metal-contaminated soil. Leachate samples (replicates) were taken from all four landfills. Heavy metal(loids) in the collected leachate samples were quantified using inductively coupled plasma mass spectrometry. The microbial strains used for bioaugmentation were isolated from the soil sample collected from Taman Beringin Landfill. X-ray fluorescence spectrometry was used to analyze heavy metal(loid)s in the soil, prior to the isolation of microbes. The results of the present study show that the treatments inoculated with the isolated bacteria had greater potential for bioremediation than the control experiment. Of the nine isolated microbial strains, the treatment regimen involving only three strains (all Gram-positive bacteria) exhibited the highest removal efficiency for heavy metal(loid)s, as observed from most of the results. With regard to new findings, a significant outcome from the present study is that selectively blended microbial species are more effective in the remediation of leachate-metal-contaminated soil, in comparison to a treatment containing a higher number of microbial species and therefore increased diversity. Although the leachate and soil samples were collected from Malaysia, there is a global appeal for the bioremediation strategy applied in this study.

Full textAbstract:
Despite initiatives for enhanced recycling and waste utilization, landfill still represents the dominant disposal path for municipal solid waste (MSW). The environmental impacts of landfills depend on several factors, including waste composition, technical barriers, landfill operation and climatic conditions. A profound evaluation of all factors and their impact is necessary in order to evaluate the environmental hazards emanating from landfills. The present paper investigates a sanitary landfill located in a semi-arid climate (Tunisia) and highlights major differences in quantitative and qualitative leachate characteristics compared to landfills situated in moderate climates. Besides the qualitative analysis of leachate samples, a quantitative analysis including the simulation of leachate generation (using the HELP model) has been conducted. The results of the analysis indicate a high load of salts (Cl, Na, inorganic nitrogen) in the leachate compared to other landfills. Furthermore the simulations with HELP model highlight that a major part of the leachate generated originates form the water content of waste.

Hasil pengujian air sumur pantau Bulan Mei 2022 yang dilakukan pada parameter fisik menunjukkan hasil yang tidak melebihi baku mutu lingkungan. Hasil pengujian air lindi pada inlet IPAL pada Bulan Mei 2022 menunjukkan nilai COD dan TSS pada inlet IPAL melebihi baku mutu lingkungan yaitu 890 mg/L dan 123 mg/L. Sedangkan pada outlet IPAL menunjukkan nilai COD melebihi baku mutu lingkungan yaitu 618 mg/L.Simpulan: Pengelolaan sampah di TPA Lempeni pada awal beroperasi pada tahun 2016 menerapkan sistem pengelolaan sampah sanitary landfill namun sejak tahun 2021 TPA Lempeni beralih menjadi controlled landfill yakni perpaduan dari sanitary landfill dan open dumping sehingga diperlukan monitoring dan evaluasi dalam penerapan sistem pengelolaan sampah agar tidak menimbulkan permasalahan sampah yang baru. ABSTRACTTitle: Analysis of the Waste Management System at the Sanitary Landfill Final Processing Site (TPA) in Lumajang RegencyBackground: One of the environmental problems that are often faced is the problem of waste. The Final Processing Site (TPA) is a place where waste has reached the final stage of waste processing. The enactment of Law of the Republic of Indonesia Number 18 of 2008 concerning Waste Management directs the rehabilitation of landfills with an open dumping system into sanitary landfills. One of the landfills that has implemented a sanitary landfill system is the Lempeni landfill in Lumajang Regency. However, the sanitary landfill method applied is not optimal. The waste is only compacted and not landfilled with soil due to the limited soil to stock up while the amount of waste is increasing. This research aims to find out the picture of the waste management system at the Lempeni landfill, Lumajang Regency.Method: This research is an observational descriptive study, conducted at the Lempeni Final Processing Site (TPA) Lumajang Regency by conducting observations, interviews, and documentation. The object of this study is the waste management system at the Lempeni Landfill (TPA) in Lumajang Regency. The study was conducted in February – May 2022. The variables in this study are the weight of the waste, facilities and infrastructure, waste management systems, the level of leachate water quality and the level of suitability of groundwater quality. In this study, descriptive analysis was applied, namely analyzing data by describing the data that had been collected without intending to make generalizing conclusions.Result: The amount of waste that entered the Lempeni landfill for 8 days of sampling was 1,418,076 kg with an average waste of 177,259.5 kg/day. The Lempeni landfill consists of two zones, namely: zone 1 has an area of 1.95 Ha with a capacity of 85,500 m3 and zone 2 has an area of 2 Ha with a capacity of 90,000 m3. Currently, the Lempeni landfill has switched to controlled landfill, which is a combination of sanitary landfill and open dumping. The results of the May 2022 monitoring well water testing conducted on physical parameters showed results that did not exceed environmental threshold value. The results of leachate water testing on the WWTP inlet in May 2022 showed that the COD and TSS values on the WWTP inlet exceeded the environmental quality standards of 890 mg/L and 123 mg/L. While at the WWTP outlet, the COD value exceeded the environmental quality standard of 618 mg/L.Conclusion: Waste management at the Lempeni landfill at the beginning of its operation in 2016 implemented a sanitary landfill waste management system but since 2021 the Lempeni landfill has switched to a controlled landfill, which is a combination of sanitary landfill and open dumping so that monitoring and evaluation are needed in the implementation of a waste management system so as not to cause new waste problems.

The gases produced from Sanitary Landfill are to be monitored and collected so as not to cause environmental pollution. TPA Bangklet in Bangli District, Bali Province iscurrently being reviewed and further developed to be pilot Sanitary Landfill in Indonesia. A system of monitoring and capturing or collecting LFG (Landfill Gas) has been done toBangklet’s Sanitary Landfill of the dry Cell Pilot Plant, especially for the second layer. LFG measurement results show the average value of 32.99% for CH4, 31.87% for CO2, 5.4% for O2 and up to 29.68% for other gases. But the arrests and the collection of LFG system still needs improvement, because there are some leaks that led to the entry of oxygen into the system and vice versa the LFG is released into the atmosphere. It is suggested that the pattern of capture, and utilization of LFG monitoring system have to be applied to all Sanitary Landfills located in Indonesia.

Full textAbstract:
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.

Monitoring of environment in regions of the location of waste landfills includes the implementation of the control over a sanitary condition of soils. The main origins of the spread ofpollutants into soils are the solid particles from aerosol emissions from the functioning of landfills transmitted to surrounding territories. Within zones of the impact of three largest waste landfills in the Saratov region (Aleksandrovsky, Guselsky in the city of Saratov and Balakovsky in the city of Balakovo) there were taken 152 soil samples. According to results of the estimation in soil concentration of gross and motile forms of heavy metals of the first (Zn, Cd, Ni) and the second danger classes (Cu, Cr, Pb) there was performed the analysis of coefficients of danger- K0 and total coefficients ofpollution - Zc. There was executed the assessment of both a sanitary and hygienic condition of soils and degree of danger ofpollution. The most contrast areal features of the distribution of the danger coefficient - Ko in soils are characteristic for motile forms of heavy metals. For all three studied objects persistently there is stood out the dangerous and areal pollution of soils by association of Ni and Cu . The danger ofpollution of soils by gross forms of heavy metals is minimum. The coefficient of total pollution of Zc exceeds admissible level on motile forms of heavy metals only for the soils surrounding the Balakovo landfill. In zones of the impact of waste landfills there are located the processed lands with an adverse sanitary and hygienic condition of soils. In the region of the Guselsky object soils of the processed agricultural grounds are dangerously polluted by motile forms of Ni and Cu. In vicinities of the Balakovo waste landfill considerable areas of private gardening enterprises are dangerously polluted by the motile forms of Ni, Cu and Zn.

This paper refers to a Municipal Solid Waste (MSW) compressibility study of waste disposed of in small scale sanitary landfills in the municipality of Presidente Lucena in the State of Rio Grande do Sul, Brazil. The research aims at the application and development of settlement prediction models based on settlement data collected on site. The studies were divided into the following stages: application of prediction models based on Soil Mechanics’ classical concepts and the creation of a regression model, based on the physical and chemical landfill monitoring results, in order to estimate differential settlements. The results showed that the application of data collected at the monitored small scale landfills through classical settlement prediction models resulted in significant errors. However, the model created based upon the regression analysis, perhaps because it considered the specifics associated with disposal techniques in small landfills, was the most realistic in terms of settlement prediction, such that it is applicable to other similar systems, be it due to the characteristics of disposed waste, as well as to the employed operational details.

The Garbage Project has excavated eight sanitary landfulls from California to Florida and analyzed 6.71 metric tons of refuse deposited between 1952 and 1988. While the ultimate goal of this continuing endeavor is to collect archaeological data on contemporary discards using a methodology that will link our society to the past, this initial report relates Garbage Project data to three issues of current public concern. This first applied archaeology of landfills has identified: (1) the contents of specific landfills and possible refinements for "national" estimates of U.S. landfill contents; (2) a link between moisture level and rate of refuse decomposition; and (3) part of the pathway of migration for heavy metals.

In recent years, the contamination of the underground resources from landfill leachates is recognised as a serious socio-economic and environmental problem in many countries. In fact, the existing not adequately controlled and abandoned sites, constitute a serious sanitary and environmental problems. The choice of the waste disposal site must necessarily arise from a rigorous study based on the joint assessment of the environmental hazard of the same plant and the hydrogeological characteristics and the degree of intrinsic vulnerability to pollution of the aquifers. In the present paper an integrated system for the assessment of the environmental risk from solid waste landfills is proposed. The integrated analysis of the intrinsic vulnerability of the aquifer system and the estimate of the intrinsic potential hazard caused by the landfill expressed in terms of danger index allow to evaluate the suitability of the sites to host a landfill and to define the reclamation priority and monitoring system for the existing landfills. As concerns new landfills, the proposed methodology could also support a better construction strategy and the protection of the surrounding environment. Finally, this methodological approach was applied in landfills located in different geological and hydrogeological contexts.

This study presents an analysis of soil contamination caused by Ni, Zn, Cd, Cu, and Pb at municipal solid waste (MSW) landfills, with a focus on ecological risk assessment. The approach aims to assess how different landfill practices and environmental conditions affect soil contamination with potentially toxic elements (PTEs) and associated environmental risks. Soil samples were collected from MSW landfills in Poland and the Czech Republic. The research included a comprehensive assessment of PTEs in soils in the context of global environmental regulations. The degree of soil contamination by PTEs was assessed using indices: Geoaccumulation Index (Igeo), Single Pollution Index (Pi), Nemerow Pollution Index (PN), and Load Capacity of a Pollutant (PLI). The ecological risk was determined using the Risk of PTEs (ERi) and Sum of Individual Potential Risk Factors (ERI). The maximum values of the indicators observed for the Radiowo landfill were as follows: Igeo = 4.04 for Cd, Pi = 24.80 for Cd, PN = 18.22 for Cd, PLI = 2.66, ERi = 744 for Cd, ERI = 771.80. The maximum values of the indicators observed for the Zdounky landfill were as follows: Igeo = 1.04 for Cu, Pi = 3.10 for Cu, PN = 2.52 for Cu, PLI = 0.27, ERi = 25 for Cd, ERI = 41.86. The soils of the tested landfills were considered to be non-saline, with electrical conductivity (EC) values less than 2,000 μS/cm. Varying levels of PTEs were observed, and geostatistical analysis highlighted hotspots indicating pollution sources. Elevated concentrations of Cd in the soil indicated potential ecological risks. Concentrations of Cu and lead Pb were well below the thresholds set by the environmental legislation in several countries. In addition, Ni concentrations in the soils of both landfills indicated that the average levels were within acceptable limits. Principal Component Analysis (PCA) revealed common sources of PTEs. The identification of specific risk points at the Radiowo and Zdounky sites contributes to a better understanding of potential hazards in landfill environments. By establishing buffer zones and implementing regular maintenance programs, emerging environmental problems can be addressed in a timely manner.

Full textAbstract:
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.

The end of municipal solid waste operations is landfill. Almost all of the Indonesia city’s landfills use the open dumping system. Generally, wastes dumped in the landfill are dominated by organic materials that potentially used for cow feeding. So that, in some landfills there are cow pasturing with the low cost operation related to the free feeding materials. According to UU No 18/2008, in the year of 2013 open dumping landfill is prohibited operate changed by sanitary landfill. Related to this change, the cow pasturingin landfill will be affected. So that the cow pasturing in landfill need to be assessed in the aspect of waste reduction, economic values, landfill operation, social conflict, and safety cow meat. The goals of this study are assessing positive and negative impacts from cow pasturing in the Piyungan Landfill, Yogjakarta. Research methods used are references study, interview, counting the cow and direct investigation of landfill operation. This study concluded that cow pasturing in landfill has positive impacts for waste reductionand increasing economic level of people live in surrounds of landfill. Unfortunately, the cow pasturing has also negative impact such as disturbing daily landfill operation, high potent social conflict during landfill rehabilitation, and high content of some heavy metals in the cow organ. Based on those impacts, the policy of the cow pasturing has to be reviewed because of the importance of sanitary landfill operation in the near future andthe issue of safely consuming meat free from heavy metals.Key Words: landfill, waste, cow pasturing

Full textAbstract:
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.

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.

Full textAbstract:
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.

Tritium content in the leachate of sanitary landfills, in concentrations well above those observed in global precipitation, can be used as a tracer for the evaluation of the contamination of groundwater in piezometers of the landfills and in neighbouring tubular wells. This possibility was first investigated in Brazil for sanitary landfills in the region of Belo Horizonte City. Tritium levels together with the content of metals present in water and the measurement of soil electrical conductivity, proved to be valuable for these studies and also as a tracer for hydrodynamic studies of the surface water in the Ressaca creek.

Open disposal is the most common technique used for municipal solid waste (MSW) management due to the absence of sanitary landfills in Pakistan. The major cities and small towns in Pakistan have become a showcase of negligence and mismanagement of MSW, which results in deterioration of the environmental and social-life quality. Moreover, research has proved that inefficient handling (disposal) of MSW results in uncontrolled emissions of greenhouse gases (GHGs), mainly methane, and adds a significant share in global climate change. This study aims to estimate methane emissions from MSW disposed of at dumpsites and compare the GHG mitigation potential of different landfill strategies in specific climate and waste compositions in Karachi. The GHG estimations are based on lab-scale investigations conducted by simulating landfill conditions through the landfill simulation reactor (LSR) experiment. The synthetic MSW sample representing the composition of MSW generated in Karachi was used in the LSR experiment. Environmental sustainability and GHG mitigation potential of different landfilling strategies was evaluated by analyzing gas formation potential (GP21) and respiration activity (RI4) at the end of the experiment. This study revealed that the quantity of solid waste annually disposed of at dumpsites in Karachi possesses the potential to release about 3.9 Mt CO2-eq. methane (with specific methane potential of 1.8 tCO2-eq./tonne DM disposed) due to the biological decomposition of the organic fraction. Results show that the fresh waste disposed of at landfill sites in Karachi possesses about 92% and 94% higher GP21 and RI4, respectively, than the German allocated criteria for mechanically and biologically treated (MBT) waste for landfills Furthermore, sanitary landfills with post-aeration conditions showed higher GHG mitigation potential and low biological activity in the waste. The second highest GHG mitigation potential and lowest biological activity of the waste was noticed from bioreactor landfills with post-aeration conditions. The third number in GHG mitigation and reduced waste activity was noticed in the waste sampled from bioreactors without aftercare approach. The least GHG mitigation potential was noticed from the uncontrolled waste dumping (existing) approach with high residual gas potential and respiration index level. This lab-scale landfill simulation study can provide baseline data for further research and planning the development of new sustainable landfills in Karachi, Pakistan and in the region.

Municipal landfill leachates are a source of toxic heavy metals that have been shown to have a detrimental effect on human health and the environment. This study aimed to assess heavy metal contamination in leachates, surface water, and sediments from non-sanitary landfills in Uyo, Nigeria, and to identify potential health and environmental effects of leachate contamination. Over the wet and dry seasons, surface water and sediment samples were collected from an impacted freshwater ecosystem, and leachates samples from six monitoring wells. Elemental analyses of samples were conducted following standard analytical procedures and methods. The results indicated that leachate, surface water, and sediment samples all had elevated levels of heavy metals, implying a significant impact from landfills. Pollution indices such as the potential ecological risk index (PERI), pollution load index (PLI), degree of contamination (Cd), modified degree of contamination (mCd), enrichment factor (EF), geoaccumulation index (Igeo), and Nemerov pollution index (NPI) were used to assess the ecological impacts of landfill leachates. The following values were derived: PERI (29.09), PLI (1.96E-07), Cd (0.13), mCd (0.16), EF (0.97–1.79E-03), Igeo (0), and NPI (0.74). Pollution indicators suggested that the sediment samples were low to moderately polluted by chemical contaminants from the non-sanitary landfills, and may pose negative risks due to bioaccumulation. Human health risks were also assessed using standard risk models. For adults, children, and kids, the incremental lifetime cancer rate (ILCR) values were within the acceptable range of 1.00E-06–1.00E-04. The lifetime carcinogenicity risks associated with oral ingestion exposure to heavy metals were 9.09E-05, 1.21E-05, and 3.60 E-05 for kids, adults, and children, respectively. The mean cumulative risk values for dermal exposures were 3.24E-07, 1.89E-06, and 1.17E-05 for adults, children, and kids, respectively. These findings emphasized the risks of human and biota exposure to contaminants from landfills.

The use of landfills has been applauded in municipal solid waste management as a critical solution to open dumping and burning. Selection of suitable landfill sites presents a challenge as it involves integration of numerous criteria in waste management and sustainability template without prejudice to the environment. The aim of this paper is to delineate appropriate sites for landfills in the basement complex of Ado-Ekiti, South-western Nigeria. The need for landfill sites that meet scientific and environmental requirements is compelling. Landsat-8 OLI & TIRS images of 2016 and ASTER imagery (30m resolution) were acquired to generate land use/land cover maps and site selection criteria. The composite image was subjected to supervised classification using the maximum likelihood algorithm in ArcGIS 10.2.2. The classification permitted the extraction of the land use of urban areas (settlements), agricultural areas, and bare land. Geoelectrical characterization was deployed to produce in situdata. Integration of data using a weighted overlay yielded a landfill suitability index map that classified the area into four categories of unsuitable, partly suitable, moderately suitable, and very suitable locations of landfill sites. Sanitary landfills are desirable to mitigate the adverse effects of widespread open dumping. Doi: 10.28991/HEF-2022-03-03-05 Full Text: PDF

Four monitoring campaigns of sedimentable dust were provided from two large non-sanitary landfills (Zrenjanin and Novi Sad) in Serbia during 2021. Particle size analysis by laser diffraction and inductively coupled plasma - optical emission spectrometry (ICP-OES) were carried out in order to obtain particle size distribution (PSD) and toxic elements (TEs) concentrations. The health risk assessment of the landfill employees was performed according to United States Environmental Protection Agency (US EPA) methods based on TEs concentrations. The particle size distribution results demonstrated that the majority of sedimentable dust samples mass were not concentrated neither within PM2.5 neither within PM10 fraction. Analysis revealed high concentration of TEs at both landfills: an extremely high concentration of Cr and Zn in samples from Zrenjanin landfill was detected. Health risk potential of elements was as follows for both landfills: Cr > Co > Pb > Ni > Zn > Cu. According to the results, maximal hazard index (HI) for landfill employees in Zrenjanin (1.97*10-1) and Novi Sad (1.13*10-1) showed that non-cancer risk was very low. For both landfill sites, cancer risk (CR) was highest for Cr (2.75*10-5 for Zrenjanin and 2.02*10-7 for Novi Sad), though still within the defined threshold for tolerable cancer risk.

Landfills are the dominant method of municipal solid waste (MSW) disposal in many developing countries, which are extremely susceptible to failure under circumstances of high pore water pressure and insufficient compaction. Catastrophic landfill failures have occurred worldwide, causing large numbers of fatalities. Tianziling landfill, one of the largest engineered sanitary landfills in China, has experienced massive deformation since January 2020, making early identification and monitoring of great significance for the purpose of risk management. The human risk posed by potential landfill failures also needs to be quantitatively evaluated. The interferometric synthetic aperture radar (InSAR) technique, unmanned aerial vehicle (UAV) photogrammetry, and ground measurements were combined to obtain landfill deformation data in this study. The integrated satellite–UAV–ground survey (ISUGS) approach ensures a comprehensive understanding of landfill deformation and evolution. The deformation characteristics obtained using the InSAR technique and UAV photogrammetry were analyzed and compared. A close relationship between the most severe mobility events, precipitation episodes, and was observed. Based on early hazard identification using ISUGS, a quantitative risk assessment (QRA) method and F-N curves were proposed, which can be applied to landfills. The comparison showed that ISUGS allowed a better understanding of the spatial and temporal evolution of the landfill and more accurate QRA results, which could be as references for local governments to take effective precautions.

The study aimed to evaluate the concentration of potentially toxic elements in the soil samples of landfill sites in An Giang province. Eighty-eight soil samples were collected from five landfills. The potentially toxic elements including Cu, Zn, Pb, Cd, and As were analysed and compared with the National technical regulations on the allowable limits of heavy metals in the soils. A cluster analysis was applied to identify the sampling sites with similar soil toxic elements properties. The ecological potential risk index was used to determine the risk of the landfills to the ecosystem. The results showed that four out of five potentially toxic elements were detected in the soil, and their concentration decreased in the order of Zn > Cu > Pb > As. Most of the potentially toxic element concentrations were within the allowable limits, except for Cu and As in some positions. The ecological potential risk index in unsanitary landfills was higher than that in a sanitary landfill; however, the level of risk was low. The occurrence of toxic elements in the soil around the landfills affects the ecosystems as well as human health. Therefore, it is necessary to prevent the effect of heavy metals in the surrounding environments.

PurposeThe study aimed to use geographic information system (GIS) based multi-criteria decision making analysis (GIS-MCDA) to select areas suitable for siting landfills in Ashanti region. It also sought to ascertain variables most sensitive to the siting of landfill in the region.Design/methodology/approachThis study utilized GIS-based Multi-criteria decision making analysis –AHP to model and select areas most suitable to siting landfills within the region. Overall, 16 variables including wind speed and hydraulic conductivity (which were previously neglected in landfill siting in Ghana) were identified through comprehensive literature review. These variables were weighted using AHP method and integrated using the weighted linear combination (WLC) in GIS environment to develop five sub-models: the physical environmental, sociocultural, economic/technical, climatic and hydrogeological sub-models. These sub-models were further weighted and then integrated to derive the final suitability model.FindingsResults show that 13% (3,067 km2) of the region was identified as most suitable to siting engineered landfills. The study also identified 11 sites which are considered most suitable for situating landfills. On a sensitivity angle, hydrogeological (R2 = 0.5923; p = 0.003) and physical environmental sub-model (R2 = 0.254; p = 0.034) significantly predicted the final suitability model developed.Practical implicationsGhana's Landfill Guidelines seeks to optimize site selection and ancillary services that culminate into achieving sanitary landfills by 2020. Evidence still abounds on the unsuitability of existing and in some cases, new landfill sites presenting environmental and social negative impacts. The comprehensive evaluation of most crucial variables – social and environmental factors that determine an optimal landfill location – will be of immense help to policy planners like the Environmental Protection Agency (EPA) towards upgraded landfills. The authors hope that, concerned agencies will adopt the model in the study and integrate into their existing landfill suitability modeling techniques to provide a more grounded framework that optimizes landfill site selection within the study area.Originality/valueThis study is the first attempt to consider a regional-level waste collection site selection in Ghana using comprehensive sets of social and environmental factors and will therefore contribute immensely to EPA's goal of achieving upgraded landfills by 2022.

Subsurface fires and smoldering events at landfills can present serious health hazards and threats to the environment. These fires are much more costly and difficult to extinguish than open fires at the landfill surface. The initiation of a subsurface fire may go unnoticed for a long period of time and undetected fires may spread over a large area. Unfortunately, not all landfill operators keep or publish heat elevation data and many landfills are not equipped with a landfill gas extraction system to control subsurface temperatures generated from the chemical reactions within. The timely and cost-effective identification of subsurface fires is an important and pressing issue. In this work, we describe a method for using satellite thermal infrared imagery at a moderate spatial resolution to identify the locations of subsurface fires and monitor their migration within landfills. The focus of this study was the Bridgeton Sanitary Landfill in Bridgeton, MO, USA where a subsurface fire was first identified in 2010 and continues to burn today. Observations from Landsat satellites over the last seventeen years were examined for surface temperature anomalies (or hot spots) that may be associated with subsurface fires. The results showed that the locations of hot spots identified in satellite imagery match the known locations of the subsurface fires. Changes in the hot-spot locations with time, as determined by in situ measurements, correspond to the spreading routes of the subsurface fires. These results indicate that the proposed approach based on satellite observations can be used as a tool for the identification of landfill subsurface fires by landfill owners/operators to monitor landfills and minimize the expenses associated with extinguishing landfill fires.

Abstract To meet the objectives, the solid urban waste generated in Naranjillo is characterized and quantified and its adequate management is proposed. For this purpose, the methodology of the United Nations Urban Management Program, the calculation of the sanitary landfill through the guide for the design, construction, and operation of manual sanitary landfills, by Jorge Jaramillo, was used. The study determined 91.14% of usable solid waste and 8.86% of unusable solid waste whose final disposal should be in the sanitary landfill. 75.72% are organic waste that have the biological treatment in the composting plant; 15.42% of inorganic solid waste should be recycled through classification in the manual segregation plant, both components should enter the economic cycle. The volume of the landfill calculated until 2030 corresponds to 1555.80m 3 for a projected population of 4695 inhabitants in that year: with an urban solid waste production of 1575.86 Kg/day. The municipality of the district of Luyando by applying the proposed model of urban solid waste will improve the quality of life of its inhabitants by avoiding the contamination of water, soil, air, and the deterioration of the landscape.

Full textAbstract:
Sanitary landfills of municipal solid waste (MSW) might be used to reduce the storage volume required at plants giving year-round treatment of olive oil mill effluent (OME). A landfill in the methanogenic stage could act as an anaerobic filter and reduce the pollutional load of the OME while also acting as a temporary storage tank. In the present work, a lysimeter in pilot scale was used to simulate a cell of a sanitary landfill. It was filled with MSW screened by a 80 mm mesh sieve mixed to municipal sludge. Results show that when OME was spread on the top of the lysimeter at a loading rate not exceeding 0.4 kgCOD/d/m3 of reactor steady methanogenic activity was maintained in the layers of refuse and a 70% removal of COD was obtained in the OME leachate collected. Higher loading rates reduced methanogenic activity and COD removal efficiency. Nevertheless, the OME collected from the bottom of the landfill was more easily treated by anaerobic digestion than was the raw OME.

Full textAbstract:
Humic substances account for the main part of the dissolved organic carbon in groundwater. Since groundwater aquifers located near to sanitary landfills usually contain higher concentrations of dissolved organic carbon, we made experiments in the laboratory to determine whether humic substances can be formed from simple non-humified organic substances by a complex micro-flora of municipal refuse. In liquid cultures incubated for two months humic substances were produced, especially when casein or starch was added. The highest amounts of humic acid-like substances were yielded from cultures inoculated with the indigenous microflora from a rotted (aerobic) landfill. Minor yields were obtained when the inoculum originated from a compacted (anaerobic) landfill or from a five years old landfill containing refuse and sewage sludge. Spectral characteristics indicated some similarities but also differences in the UV and visible regions between the newly formed humic acids and a humic acid from groundwater.

Abstract One closed uncontrolled landfill, the Neihu garbage dump, and one active controlled landfill, the Sanzhuku sanitary landfill, were selected for investigation of their leachate characteristics and effects on adjacent river water quality before and after rainfall in northern Taiwan. A total of seven samplings were made during February and June 2007, with four samplings done after individual rainfall events on study sites. Water quality of runoff samples collected from the Sanzhuku sanitary landfill showed less pollution than the water quality of leachates collected from the Neihu garbage dump; however, some water quality levels of leachate samples collected from the Neihu garbage dump were relatively high, such as ammonia nitrogen (NH3-N), orthophosphate (PO43-) and biochemical oxygen demand (BOD5). At the uncontrolled dump, rainfall lead to dilution effects on river water NH3-N and PO43- concentrations, but not other water quality parameters. In contrast, the concentrations of bisphenol A (BPA) and nonylphenol were increased in both types of landfills after rainfall in the present study. Dilution effects of rainfall on most water quality parameters and toxicity tests were observed in the Neihu garbage dump leachates after rainfall, but not for the Sanzhuku Landfill runoff. The highest concentration of BPA measured in this study was 25.8 μg L-1 in the Sanzhuku sanitary landfill runoff after the heaviest rainfall event, during which 236 mm of rainfall accumulated over four days. The results of this study suggest that both uncontrolled and controlled landfill leachates can be an important potential pollution source of BPA to adjacent water bodies.

In Bosnia and Herzegovina, there is a large number of non-sanitary landfills and landfills where pharmaceutical waste from households is being disposed, as well as the medical waste from different health institutions. Expired pharmaceuticals are mostly being disposed there, because there is very little attention paid on waste sorting at the place of its origin. Now days, there are thousands of different medicine, and mainly, along with the other household waste, expired antibiotics are disposed of too. Degradation of expired pharmaceuticals in the environment very often leads to formation of products with completely different properties in regards to the original compound, but also it is not uncommon for those newly formed products to be more toxic than the original ones. This paper analyses the impact of rainwater infiltration on the body of the landfill where expired pharmaceuticals are being disposed of, as well as other medical waste at municipal landfills in Bosnia and Herzegovina. Field studies on the size of the rainwater infiltration as a function of different parameters have been conducted, and also degradation analysis of different expired drugs that are being disposed of in landfills has been performed.

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.
