Full textAbstract:
Management of wastes which is a part of the daily activities of man is an important aspect of environmental management. Over the years, there have been concerted efforts made towards adequately solving the problems created by improper waste management and disposal in Nigeria cities. This study, appraises environmental management in cities; a perspective from the Ondo state Waste Management Authority (OSWMA) Akure. The broad objectives of this study are to identify types of wastes managed by OSWMA, describe the attitude and role of residents (household) toward solid waste management, and examine the possible constraints faced by OSWMA, Akure in the discharge of their duties. Samples were drawn from the total number of OSWMA staff and clients served by the authority in the core, transition and peripheral districts of Akure. 53 questionnaires were administered to the staff representing 10% of the total number of staff while 324 questionnaires representing 1% of residents were administered, collated and analyzed using SPSS version 19. The results of the analysis, revealed that majority (81.1%) of the staff respondents opined that the type of waste managed by the Authority is solid waste; using the door to door method of solid waste collection as submitted by 54.5% of the staff. On the other hand, majority of the households’ respondents (81.4%) expressed willingness to pay for service rendered by the authority. Findings also revealed that poor funding was the main constraints faced by the authority. The study therefore recommends proper funding, provision of equipment and facilities needed for smooth running of the authority in order to ensure effective collection and management of waste in the study area.

Full textAbstract:
Processed soybeans such as tempeh and tofu are some of the foods that the people of Indonesia favour. The Tempe and Tofu processing factory produce tofu with the essential soybean ingredients as much as 17 kg every day. The tofu production process starts from soybean immersion, grinding, boiling, filtering, compaction, moulding, cutting, to frying tofu. Production activities from the tofu industry will certainly produce solid and wastewater. These wastes can have a negative impact on the environment. Therefore, the waste must be managed and treated correctly to create an environmentally friendly industry and improve environmental quality. Tofu industry waste management and treatment can be done by identifying the generation of waste that is a priority to be treated and choosing waste treatment technology. There are three alternatives for wastewater treatment from the tofu industry: the chlorine in wastewater, ponds by forming biofilms using biofilter media, and Trickling Filters.

Full textAbstract:
Effective management of an urban solid waste system (USWS) is crucial for balancing the tradeoff between economic development and environment protection. A factorial ecological-extended physical input-output model (FE-PIOM) was developed for identifying an optimal urban solid waste path in an USWS. The FE-PIOM integrates physical input-output model (PIOM), ecological network analysis (ENA), and fractional factorial analysis (FFA) into a general framework. The FE-PIOM can analyze waste production flows and ecological relationships among sectors, quantify key factor interactions on USWS performance, and finally provide a sound waste production control path. The FE-PIOM is applied to managing the USWS of Fujian Province in China. The major findings are: (i) waste is mainly generated from primary manufacturing (PM) and advanced manufacturing (AM), accounting for 30% and 38% of the total amount; (ii) AM is the biggest sector that controls the productions of other sectors (weight is from 35% to 50%); (iii) the USWS is mutualistic, where direct consumption coefficients of AM and PM are key factors that have negative effects on solid waste production intensity; (iv) the commodity consumption of AM and PM from other sectors, as well as economic activities of CON, TRA and OTH, should both decrease by 20%, which would be beneficial to the sustainability of the USWS.

Full textAbstract:
The manufacturing industry is one of the most influential sectors contributing to greenhouse gas emissions. As the manufacturing industry strives to achieve its profit goal, most of them face various circumstances to control the rising carbon emissions from the energy, raw material consumption, and waste generations due to production activities. Therefore, it is difficult to quantify the amount of carbon emission reduction if the adjustment is not established according to the manufacturing output. This research concentrates on evaluating energy consumption and waste generation using a statistical approach by a coconut milk processing plant. This research aims to estimate the reduction of greenhouse gas emissions, mainly carbon dioxide (CO2). The baseline models of energy consumptions and waste generations were constructed using single and multiple linear regression methods. Besides, it investigates the performance of ultimate models of electrical consumption, water consumption, fuel consumption, solid waste generation, and wastewater generations using statistical analysis that involves coefficient of correlation, coefficient of determination, analysis of variance (ANOVA), etc. It indicates that with the implementation of the cleaner production (CP) strategy, the plant had reduced 10,474.94 tons of CO2 and 2,579.67 tons of CO2 in 2018 and 2019, respectively. This study is an aid to the management and engineers of the industry to investigate their accomplishment in reducing environmental impacts caused by production activities from any implementation made such as CP and green industry practices.

Full textAbstract:
The issue of solid waste is increasingly urgent to be handled by the Gresik district government. Population growth and socio-economic activities in this area have a positive correlation with the increase in the amount and type of waste. This condition will certainly threaten the regional ecosystem, so collaboration between the government, the community and the private sector is needed in integrated waste management. The research objectives are to identify the existing condition of integrated waste management in Gresik Regency, to map the driving and inhibiting factors in integrated waste management and to formulate a model format for an integrated waste management paradigm change. The research method uses a qualitative descriptive approach to obtain a complete description of the collaboration model in integrated waste management. Sources of data obtained from secondary data, literature studies, interviews and observations. Informants consist of the Head of the Department of Cleanliness and the Environment and his staff, the public and the private sector. Methods of data collection is done by using interviews, focused group and discussion. Data analysis was carried out using qualitative analysis from Miles and Huberman consisting of four components, namely: data collection (data collection), data condensation (data condensation), data presentation (data display) and conclusion drawing or verification (conclusion and verifying drawing). The results of the study indicate that waste management in Gresik Regency which is carried out in an integrated manner with the collaborative involvement of stakeholders has not been able to be carried out optimally and completely until it reaches the Final Disposal Site. The potential of resources owned by the Gresik Regency Government structurally has not been able to optimally solve problems in waste management. There are encouraging and inhibiting factors originating from the systemic conditions of the Gresik Regency Government which do not run proportionally in overcoming the problem of waste management. The existence of an alternative model of changing the paradigm of integrated waste management is possible to overcome the problems of waste
management in Gresik Regency.

Full textAbstract:
Environmental degradation is a major challenge which requires appropriate strategies to reverse the situation. One of such strategies is experiential environmental education among high school students who, through change of attitudes and behavior, are able to participate in various environmental management activities. In this study the pro-environmental attitudes and behavior of high school students in Murang’a County, Kenya were examined to assess how environmental education programmes among the students affected environmental issues of waste management, water resources management, natural resources management and climate change in the schools. Nine hundred and sixty-one (961) students from nineteen (19) high schools from two sub-counties in the County was used in the study. The Likert type questionnaire and the 2-MEV Scale were used to collect the required data. The t-test statistic was applied to determine any differences between the variables. Results showed significant differences in pro-environmental attitudes and behavior with regard to solid waste management, water resources management, natural resources management. There were significant differences with regard to solid waste management, natural resources management, climate change and environmental concerns between members of Environmental Clubs and non-members. Pro-environmental attitudes and behavior were influenced by current membership of the Clubs rather than past membership. It is concluded that experiential environmental programmes improve the student’s pro-environmental attitudes and behavior hence environmental management within the schools. It is recommended that appropriate policies be formulated to enhance the implementation of school experiential environmental programmes to ensure capacity building of the learners to effectively manage environmental issues in the schools.

Full textAbstract:
Over recent decades there has been rapid increase in the industrial waste materials and by-products yields due to the progressive growth rate of population, development of industry and technology and the growth of consumerism. With the growing environmental pressures to reduce waste and pollution, Intensive research studies have been conducted to explore all suitable reuse methods. Wastes such as construction waste, blast furnace, steel slag, coal fly ash and bottom ash have been approved in many places as alternative materials in bridges, roads, pavements, foundations and building construction. The use of industrial solid waste as a partial replacement of raw materials in construction activities not only saves landfill space but also reduces the demand for extraction of natural raw materials. Ferrochrome slag is a by-product from the production of chrome. There are environmental and economic advantages in seeing slags as a potentially useful resource rather than as waste products. Slag management at ferrochrome producing companies has been influenced by the limited space available and financial cost implications of the slag dumps. Internationally, e.g. South Africa, India, Norway, Turkey, East Europe, China, Sweden and USA, ferrochrome slag is used commercially in the road and construction Industries. This material is being used for road construction, as aggregates in concrete industry, brick manufacturing, and in pavement construction as engineering fill and has recently been tried in cement. This paper presents an overview of the recent advances of the use of ferrochrome slag in various civil engineering applications such as road construction, and cement and concrete industries.

"Productivity improvement in solid waste recycling centres through lean implementation aided by multi-criteria decision analysis." Benchmarking: An International Journal 25, no. 5 (July 2, 2018): 1480–99. http://dx.doi.org/10.1108/bij-01-2017-0013.
Full textAbstract:
Purpose The purpose of this paper is to investigate, through a comparative analysis, the applicability of lean manufacturing practices, such as value stream mapping (VSM), for productivity improvement in recycling centres (RCs) aided by multi-criteria decision analysis. Design/methodology/approach The study is carried out in five RCs that sort the municipal solid waste of Porto Alegre, one of the main cities in Brazil. Since all of the centres present their labour composed by poor communities’ members, cultural and social characteristics may represent an incremental challenge for lean implementation. Further, these centres are organised in cooperatives, in which decisions are taken through a participatory way and all their members are entitled to vote, undermining and retarding the decision-making process. Findings The integration of a multi-criteria decision-making tool to the lean practices enables the prioritisation of improvements, complementing the final stage of VSM. In particular, this contribution becomes especially important in cooperatives managed by community, where decisions are often complex and time-consuming. Finally, despite the increasing pressure for better performance of RCs, the existent mindset is still far from the private sector, where lean practices were conceived. Further, the findings suggest that, despite processes similarities, it is not feasible to declare the existence of a one-best practice to such scenario. Originality/value In theoretical terms, the authors demonstrate through a multi-case study the adequacy of analytic hierarchy process as a decision analysis tool complementary to the VSM, enabling a broader perspective about this subject. Concerning the practical contribution, the comprehension of the adaptation needs for lean practices implementation within the production context of solid waste RCs provides a framework with guidelines for this sector, when incorporating lean activities. Lean practitioners and eventual municipal authorities involved in improving productivity of community-managed RCs might benefit from this framework, since they will be able to emphasise the development of recommended and already tested lean practices that tend to improve their operational performance.

Resumo Com a existência de um limite entre o esgotamento dos recursos naturais e do crescimento econômico, evidencia-se a necessidade de encontrar meios para compatibilizar a conservação ambiental e o crescimento econômico. Nesse cenário, desponta a gestão ambiental, que visa reduzir os impactos causados ao meio ambiente advindos das atividades econômicas das empresas. Cumpre destacar que a geração de resíduos se apresenta como aspecto indissociável do processo industrial, que demanda investimentos para a sua adequada destinação final. Nesse contexto, o objetivo com este trabalho foi analisar os custos ambientais relacionados com a gestão de resíduos em indústrias químicas localizadas na região metropolitana de Porto Alegre. Os dados foram coletados por meio de uma pesquisa survey com gestores de 36 empresas da unidade de análise. As evidências coletadas facultaram a constatação de que os resíduos representam a maior parte dos passivos ambientais nas empresas investigadas. Além disso, grande parte dos respondentes declarou que nas empresas que desenvolvem suas atividades, os passivos são tratados por meio da comercialização dos resíduos gerados pelo processo produtivo, a fim de obter receita adicional. De acordo com 24 respondentes, os resíduos sólidos gerados em um processo produtivo são reaproveitados na produção de outro produto, e os gestores que responderam que não conseguem sequer gerar receita adicional, via comercialização de resíduos, tampouco aproveitar resíduos na fabricação de outro produto, alegaram dificuldade operacional para viabilizar o referido modelo, ou falta de organização interna para mapear os resíduos sólidos gerados no processo.Palavras-chave: Gestão de resíduos. Custos ambientais. Indústria química. Abstract With the existence of a limit between the exhaustion of natural resources and the economic growth, it is highlighted the need to find ways to reconcile environmental conservation and economic growth. In this scenario, comes up environmental management, which aims to reduce the impacts to the environment arising from the economic activities of enterprises. It should be noted that the generation of waste is presented as an inseparable aspect from the manufacturing process, which requires investments for its proper disposal. In this context, the aim of this study was to analyze the environmental costs related to waste management in chemical industries located in the metropolitan area of Porto Alegre. The data were collected through a survey research with managers of 36 companies unit analysis. Evidence collected provided the realization that the waste represent most of the environmental damage in the investigated companies. In addition, most respondents stated that in companies that develop their activities, liabilities are treated through the marketing of waste generated by the production process in order to obtain additional revenue. According to 24 respondents, the solid waste generated in a production process are reused in the production of another product, and the managers who responded that they cannot even generate additional revenue via marketing waste, either take advantage of waste in the manufacture of another product, alleged operational difficulty to enable that model, or lack of internal organization to map the solid waste generated in the process.Keywords: Wastes.

Municipal solid waste (MSW) management has an impact on climate generating greenhouse gases (GHG). To quantify GHG emission from MSW management activities (transportation, composting, recycling and landfill), this study was conducted in the Chittagong City Corporation (CCC). Data were collected about detail MSW management activities of the CCC through conducting a structured questionnaire survey on related personnel with MSW management. To collect data about recycling, another questionnaire survey was conducted on all junkshops near to both dumping sites (Anandabazar and Arefin Nogor) of the CCC. The study found that, composting and recycling of MSW have a positive contribution in reducing GHG emission. Transportation and land-filling of MSW have a contribution in GHG emission. The amount of GHG emission from the existing MSW management system of the CCC is 31,904.68 tons of CO2-eq per month. The life cycle assessment (LCA) study on composting shows that, the reduction of GHG emission is 3.66 tons of CO2-eq per ton of produced compost. The study finding is expected to contribute to the field of climate change mitigation in Bangladesh.

The study was conducted to investigate the present solid waste management practice in Mymensingh municipal area especially in Ward 04 and 06. Huge solid wastes are generated every day in these wards but the waste management is not properly done because of their irregular waste management activities or unconsciousness. Maximum respondents discharged 1kg solid waste from their households per day and the respondents were 64%. Other 18% household discharged 0.5 kg and another 18% discharged 2 kg solid waste from their house per day. A majority percent of people dumps the produced solid waste in their living surroundings which produce various hazards in human health and environmental problems. This improper waste management can be managed by the regularity of management work, building awareness of the people and improving waste treatment. The municipality and other related NGOs should work together to solve these issues. It was revealed from the study that due to lack of people knowledge about solid waste management, lack of adequate budget for waste management, lack of available transport vehicles for waste management, lack of proper solid waste treatment plant etc. The total solid waste management system required following the recommendation which include proper planning, creating awareness, developing infrastructure, providing logistic support and finally involving NGOs, CBOs, public in this process. A sustainable solid waste management can be established which can lead the studied area to a healthy setting.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14813 J. Environ.

Household waste and uncontrolled urbanization management are considered major problems in African countries. In the Hodna region, the phenomenon seems to be more important in urban centers because of the huge amount of household waste generated by domestic and commercial activities. In most Algerian cities, solid waste is piled up in huge quantities in dumps and is dumped indiscriminately in waterways and public spaces. Uncontrolled urbanization, industrial development, and the evolution of lifestyle lead to increased production of waste, whereas the waste management techniques used in urban areas should be reconsidered. From this perspective, this paper studies and analyses in a spatio-temporal approach, the practices of household waste management in the city of M’sila in order to evaluate the state of such management and identify the key elements of integrated planning of waste management.

Solid waste is an inevitable by-product of human beings, animals and also of industrial-commercial activities. Obviously solid waste creates a greater problem to the environment, if it is not properly managed. Bangladesh being a heavily populated country needs to pay adequate attention to waste management. Waste generation in Bangladesh is increasing because of rapid urbanization and economic development of the country. At present, total solid waste generation in Bangladesh is around 27000 tons/day and in the four important city corporations is about 13,332 tons. Particularly in Dhaka city, it is around 7500 tons/day. This amount is likely to reach about 47000 tons per day in entire Bangladesh and 15000 tons per day for Dhaka city alone by 2030. At present, landfilling is the only method for disposal of heterogeneous waste stream and there are three landfills in Dhaka City. Most of these landfill sites are in open dumps polluting land, water and air. Development of any new landfill site is near to impossible due to land scarcity and increasing of land prices especially in Dhaka City. Improperly disposed waste is posing serious health implications to the people and it may transmit various diseases especially by non-degradable wastes like polythene. Rather, a proper Segregation system to recover of resource from plastic wastes can play a very important role in mitigating the difficulties of solid waste that can act as a raw material for product design in Bangladesh too. Therefore, a comprehensive study report followed by a model of plastic waste segregation system for Bangladesh has been highlighted in the paper.

Universitas Diponegoro has a role in contributing to considerable numbers of hazardous solid waste from academic activities as it is the largest university in Central Java Province, Indonesia. Therefore, improper hazardous solid waste will cause potential disease for humans and pollute the environment. For this reason, proper hazardous solid waste management is urgently needed. This research aims to design hazardous solid waste management for Universitas Diponegoro as a pilot testing study. The research used questionnaires, surveys, in-depth interviews, and observations to construct an appropriate hazardous waste management system. The result showed that hazardous solid waste in Universitas Diponegoro came from 5 sources: education, office, laboratory, supporting facilities, and Pleburan Campus. The estimation of hazardous solid waste produced by the Universitas Diponegoro in 2021 is as much as 100.4 kg/day. The hazardous waste characteristics are toxic, corrosive, flammable, and infectious. In the hazardous management planning that was developed, the design of the waste transportation and storage system at the waste station in the Tembalang and Pleburan campuses has a total investment and operation cost of Rp 6,259,841,999 for 10 years of operation. This design is hoped to enhance the campus's achievement in sustainability efforts.

Full textAbstract:
Fresh markets or wet markets function as important places for exchanging food stuffs and meeting of local people in many emerging economies. Through many activities in fresh markets, solid waste is substantially generated and becomes a main environmental issue. In Ubon Ratchathani, Thailand, solid waste in fresh markets emerges as an environmental issue with potentials to be improved. Selecting two fresh markets with different ownerships in Ubon Ratchathani, the concepts of waste hierarchy and triad-network model were applied to study and compare ways to improve solid waste management systems. Through focus group discussions and semi-structured interviews, this research reveals that solid waste managements of the two markets are centrally organized by the owners with the emphasis on tidiness with little involvements from other actors. To improve waste managements, moving beyond legal requirements and engaging relevant actors are essential. It is also found that different ownership (public vs. private) affects how fresh markets can organize improvement strategies.

Principally, solid waste management is all activities of solid waste handling, from thepoint sources until the final disposal. Up to know solid waste management in urban areais still a complex problem, either from social, management, and technology aspects.The other problem of solid waste management is due to the people behaviour, whichis mostly still unaware. Social capacity is another word social capital means a socialcondition that a lot of citizens participate the process of decision making or policymaking and cooperation with government. The role of community in this system is onlyin paying the monthly fee. So that people still fully gave the solid waste managementsystem in to the government. There is no indication of solid waste sparation by thepeople them selves.

Lae city is the capital of the Morobe Province in Papua New Guinea. It is the main land transport corridor, the country's main industrial hub and largest cargo port. As a result of the urbanization and industrialization process, more people had migrated to Lae city for better opportunities. These activities contributed to the generation of a considerable amount of solid waste that has become a real concern. The present research aims to understand the existing practices of Solid Waste Management, to estimate per capita waste generation rate and composition of waste, to identify the issues and challenges faced in this regard and suggest methods for improvement. All wastes from the city are discarded at the Second Seventh Landfill (SSL) open dump site, located about 10 to 12 kilometers drive away from the city, causing enormous pollution to the surrounding environment. The per capita waste generation rate witnessed was 0.312 kg per capita per day with a composition of 66% organic waste, 22% recyclable, and 12% non-recyclable materials. It was found that ineffective legislation, lack of law enforcement were the challenges faced by the Lae city council. Rehabilitation of SSL or the construction of a new sanitary land fill should be recommended for effective management.

Nowadays, the huge production of Municipal Solid Waste (MSW) is one of the most strongly felt environmental issues. Consequently, the European Union (EU) delivers laws and regulations for better waste management, identifying the essential requirements for waste disposal operations and the characteristics that make waste hazardous to human health and the environment. In Italy, environmental regulations define, among other things, the characteristics of sites to be classified as “potentially contaminated”. From this perspective, the Basilicata region is currently one of the Italian regions with the highest number of potentially polluted sites in proportion to the number of inhabitants. This research aimed to identify the possible effects of potentially toxic element (PTE) pollution due to waste disposal activities in three “potentially contaminated” sites in southern Italy. The area was affected by a release of inorganic pollutants with values over the thresholds ruled by national/European legislation. Potential physiological efficiency variations of vegetation were analyzed through the multitemporal processing of satellite images. Landsat 5 Thematic Mapper (TM) and Landsat 8 Operational Land Imager (OLI) images were used to calculate the trend in the Normalized Difference Vegetation Index (NDVI) over the years. The multitemporal trends were analyzed using the median of the non-parametric Theil–Sen estimator. Finally, the Mann–Kendall test was applied to evaluate trend significance featuring areas according to the contamination effects on investigated vegetation. The applied procedure led to the exclusion of significant effects on vegetation due to PTEs. Thus, waste disposal activities during previous years do not seem to have significantly affected vegetation around targeted sites.

Textile manufacturing sector is the strongest root of the economy of Bangladesh while pollution by inappropriate management of waste water from textile dyeing industries is one of the major environmental problems. Textile processing employs an assortment of chemicals, contingent upon the idea of the crude materials and items. Environmental problems caused by the the textile industry are mainly the discharges of waste water. The wellspring of waste water contamination are the wet handling steps which incorporate measuring, desizing, scouring, bleaching, mercerizing, coloring, printing etc. The present study was aimed at physico-chemical evaluation of waste water discharged by some garments industries. While in some waste water high pH values have been recorded, the pH values of the waste water before and after treatments were found in between the standard range. The Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solid (TDS) and Total Suspended Solid (TSS) values for waste water before treatment were found to be much higher than the permissible limits. For some industries the BOD, COD, TDS and TSS values of the outlet water from effluent treatment plant (ETP) were also found beyond the standard limits.

Abstract The fishing port is an important supporting facility for achieving high-quality of fishery production. Maintaining the quality of fishery products is needed by optimizing the function of fishing ports as they are the cutting edge and a prime mover in the management and utilization of fish resources and port environment, ranging from preproduction, production, processing, and marketing. On the other hand, the fishing port has various environmental problems such as waste management, water quality degradation and liquid waste management. The objective of this study is to identify the solid waste input to a fishing port by using remote sensing approach. The research was conducted in Karangantu Fishing Port (Pelabuhan Perikanan Nusantara Karangantu), located in Serang, Banten. This study shows that the high-resolution satellite imagery was proven to be able to estimate the solid waste input to the fishing port area. The result shows that solid waste input to Karangantu Fishing Port was estimated to be 142.95 tons in 2020, which was derived from office activities, shipping activities, and tourist activities surrounding fishing port area. The method approach from this study is expected to support environmental management in the other fishing port areas.

Solid Refuse Fuel (SRF) manufacturing facilities process 4.72 million tons of waste annually. The residues generated after manufacturing SRF products account for 35–40% of the input waste, and most of them are finally disposed of in landfills. The process flow and management status of SRF manufacturing facilities were investigated, and the residues generated from SRF manufacturing facilities using municipaland industrial waste, respectively, were separated by particle size. The appropriate separation conditions for the residues according to the characteristics of the input raw materials were presented through the analysis of loss on ignition (LOI), organic foreign substance content, heating value, and carbon content. Based on this, the appropriate management criteria (draft) for the subsequent treatment of final residues were derived to improve recyclability. Residues generated in the SRF manufacturing process need to be additionally separated into combustibles and incombustibles through cylindrical rotary separating devices before subsequent the final disposal process.

Full textAbstract:
This article discusses the chemical management of wastewater in hospitals. Liquid waste is all wastewater including feces originating from hospital activities which may contain pathogenic microorganisms, toxic chemicals and radioactive substances that are harmful to health. Therefore, the potential impact of hospital wastewater on public health is very large, so each hospital is required to treat its wastewater until it meets the applicable standard requirements. Good wastewater management is not only for sharp medical wastes but covers hospital waste as a whole. With the increasing number of health service facilities, it will result in an increasing potential for environmental pollution, because waste disposal activities, especially waste water, will contribute to decreasing the level of human health. Hospital waste is all waste generated from hospital activities in the form of solid, liquid and gas. It is better if hospital waste has a waste storage and treats the waste first before discharging it into the environment, so that the environment is not polluted and the government should build a monitoring system.

Full textAbstract:
The management of municipal solid waste is a crucial issue to address as we move toward the decarbonization of urban contexts. Not by chance, this sector plays a relevant role in the Covenant of Mayors program, whereby municipalities are called to design their own Sustainable Energy Action Plans (SECAPs). However, despite new regulations strongly pushing the recycling and reuse of materials contained in municipal waste, many cities still use large landfills. As part of the overall environmental pressure exerted by these urban systems, the transport of waste from collection points to landfills or treatment facilities must be considered in order to correctly assess the full environmental burden of waste management. To this aim, in this paper, the Ecological Footprint method is applied to the municipal solid waste management system of the city of Palermo (Sicily). The results show that the impacts produced by the means of transport used, both in the status quo and in the assumed enhanced scenario (with less municipal waste disposed to landfills in favor of recycling), are significant compared to those caused by the other segments of the waste management system. The concept of a “saved footprint” is also introduced here, in order to properly compare the two scenarios.

Full textAbstract:
Contemporary industry is beginning to realize the negative impact that they have on the environment in terms of greenhouse gas emissions, destruction of natural habitats, hazardous waste emissions, etc. This new found consciousness has prompted a second look on part of the manufactures at how modern manufacturing practices can be modified so as to be more environmentally friendly. Environmental impact of manufacturing can be minimized in various ways. In this context, management is often called upon to provide active leadership in managing their facilities so as to minimize their environmental impact. Some examples of such activities include green supply chains and design for disassembly. Such activities help to create a closed loop product lifecycle that is required to reduce the amount of raw material used and the amount of waste created by production. Similarly using design for manufacturability principles aid in the minimization of raw material used and waste generated as well. Also, facilities are starting to move away from reactive approaches to environmental issues. They are now using proactive approaches and value seeking approaches where the environmental issues are dealt with before they are created. This paper presents an overview of environment conscious manufacturing practices that seek to minimize the negative environmental impact of manufacturing. Being a literature review, this paper primarily deals with state of the art in current practice pertaining to green manufacturing.

The study sought to assess the social context of solid waste disposal pattern of residents in Ibadan metropolis, in order to assess the Solid waste disposal patterns of people in Ibadan metropolis, Oyo State, Nigeria. Specifically, the study identified solid waste disposal habits of residents, frequency of clearing the dumpsters, accessibility of waste dumpsters to people determines the waste disposal pattern of people; and analyze the willingness of people in Ibadan to pay for improved service. Solid waste management has been part of human activities right from time. Efforts by Oyo State Government is seen in the collection of dirt that have been placed on the medians. Waste generation is an unavoidable product of man activities, however, sustainable management of such waste is a challenge faced in many countries today. Nigeria, a developing country in Africa, has been in a quandary of how to efficiently manage the municipal solid waste its population generates. Many states in the country lack adequate plans and infrastructure required for efficient and sustainable management of municipal solid waste. For Ibadan, the largest city in Nigeria, the problem is further compounded by its rather large and still increasing population. In this research, Ibadan metropolis is taken as a case study; the rate of solid waste handling in households as regards solid waste management from household collection to final disposal are focused upon. The study found out that 45.6% drop their refuse in the dumpsters as 18.8% burns their refuse, 17.7% of the respondents drops their waste on the median, 12% in the drainage while 6% opts to drop their waste in the streams. On the effectiveness of the Private operators collecting waste from the respondents, the study found out that 7.6% effective, 37.5% of the respondents says the operators waste collection is poor, 7% says it is abysmal while 43.5% said it is not applicable to them because they do not have storage containers in their houses and as a result did not subscribe to their service. Many countries, particularly the developed ones, have employed options in the waste management hierarchy for sustainable management of their municipal solid waste and the blend of options employed is usually highly dependent on local factors. Following the waste management hierarchy, possible options for sustainable municipal solid waste management in Ibadan are discussed. It is concluded that waste reduction, reuse, and recycling are potential management options for the state. Landfilling will remain an important option for final disposal but reliance on this method could be significantly reduced if management options are exploited to the maximum in a sustainable solid waste management structure in Ibadan metropolis.

In most developing countries, solid waste components are generally commingled. Sorting of solid waste is one of the most important activities in the material recovering process of the integrated solid waste management system. If solid waste is sorted, about 30% of the work is done. Several methods exist for sorting comingled solid waste. The work presented in this paper involved the study of solid waste source sorting alternatives in Nigerian Universities. A site-specific study was carried out to characterize the solid waste generated in the University of Benin. Alternative concepts for sorting of solid waste were considered and evaluated. Source sorting was then selected for this study. The study revealed that about 14.56% of biodegradables, 42.26% of plastics, 39.62% of paper waste and 3.56% of metal waste are generated in the office and classroom areas of University of Benin. The study also showed that there is poor attitude to solid waste issues as the maximum cooperation realized on source sorting of solid waste was only about 50% for the waste-bin designated for plastic. The results obtained from the study also indicated that intensive sensitization of the generators on the benefits of source sorting is required for effective source sorting.

Full textAbstract:
The ecosystem of earth, the habitation of 7.53 billion people and more than 8.7 million species, is being imbalanced by anthropogenic activities. The ever-increasing human population and race of industrialization is an exacerbated threat to the ecosystem. At present, the global average waste generation per person is articulated as 494 kg/year, an enormous amount of household waste (HSW) that ultimately hits 3.71×1012 kg of waste in one year. The ultimate destination of HSW is a burning issue because open dumping and burning as the main waste treatment and final disposal systems create catastrophic environmental limitations. This paper strives to contribute to this issue of HSW management that matters to everyone’s business, specifically to developing nations. The HSW management system of the world’s 12th largest city and 24th most polluted city, Karachi, was studied with the aim of generating possible economic gains by recycling HSWs. In this regard, the authors surveyed dumping sites for sample collection. The sample was segregated physically to determine the content type (organic, metals, and many others). Afterward, chemical analysis on AAS (Atomic Absorption Spectrophotometry) of debris and soil from a landfill site was performed. HSW is classified and quantified into major classes of household materials. The concentrations of e-waste [Cu], industrial development indicator [Fe], and the main component of lead-acid storage batteries [Pb] are quantified as 199.5, 428.5, and 108.5 ppm, respectively. The annual generation of the aforementioned metals as waste recovery is articulated as 1.2 × 106, 2.6 × 106 and 6.5 × 105 kg, respectively. Significantly, this study concluded that a results-based metal recovery worth 6.1 million USD is discarded every year in HSW management practices.

Solid waste management is a disturbing issue in Nigerian cities as waste generation is increasing. The informal waste management sector has intensified efforts partly due to failure of government to manage waste effectively in the country. Hence, this study focuses on activities of waste recyclers in a rapidly growing city of Nigeria Ota in Ogun State. Its specific objectives are to examine spatial attributes of recycling depots, and examine recycling potentials and challenges. Data were obtained through semi-structured interview and observation. 11 recycling depot operators (recyclers) were purposively interviewed out of 20 operators making up the Recyclers Association. Majority of recycling depots are secured on a lease agreement with monthly rent ranging from N4,000 (US$11.11) to N21,667 (US$60.19). 72.7% recyclers are motivated by job opportunities made possible by recycling: 65% of recycling workers at the recymonthly salary is between N4,500 (US$12.50) and N15,000 (US$41.67). Major challenges of recyclers are lack of funds, complaint by neighbors and non-recognition by the government. Recycling depots are not regulated by government agencies and thus, recycling depots develop without planning permits. Finally, recommendations toward achieving sustainable recycling were presented.

Solid waste management that has implemented in Gili Air has not been able to cope optimally with the increase in waste volume originating from residents and tourists. As a consideration in optimizing the volume of waste that can be accommodated and managed, the carrying capacity approach can be used. The physical support of waste will be the basis for determining the maximum population on Gili Air. This research aims to measure the maximum population found in Gili Air based on the physical support of waste analysis. The key informants was given questions regarding the solid waste management system to obtain primary data, while secondary data obtained from related bureaus in the local government. The qualitative descriptive methods was used to analyze primary data from the interview, and carrying capacity and waste capacity analysis for secondary data. Waste management activities on the island limited to container and collection activities. The waste pile transported by barge to the landfill on the main island. The tourism business was imposed a levy tax according to the volume of waste generated. The potential of recyclable waste is lower than the potential for generation, so the carrying capacity of waste is relatively low with an index of 0,20. The potential for piled waste that has not managed properly is 1,230.86 kg per day. Following the calculation results of the physical support of waste, the maximum population size that Gili Air can accommodate is 2,795 people per day. The excess number of tourists as many as 585 people per day causes the solid waste management system overwhelmed.Keywords: Physical carrying capacity; Solid waste management; Small islands population; Marine tourism; Tourism impacts.

If this B3 medical waste is not managed properly, it can potentially transmit and be contaminated by infectious substances. Management of infectious waste from self-quarantine patients was minimal because most people did not know about it, and there was a lack of infrastructure from the government. Therefore the researchers were interested in researching the management of B3 waste, substantial B3 waste, from people who carried out Covid-19 self-quarantine. This study aimed to determine the community's effectiveness in managing solid medical B3 waste from COVID-19 self-quarantine activities. Using the snowball sampling method and cross-sectional design, the results showed that there was a significant relationship between Attitude (P Value = 0.000), Knowledge (P value = 0.006), Age (P Value = 0.019), Gender (P value = 0.000), Occupation (P value = 0.000) and Education (P value = 0.04) on community behavior in managing B3 medical waste during the Covid-19 self-quarantine period. Management of Solid B3 Medical Waste from self-quarantine has not been effective since its application is still low, and local drop boxes were not available as temporary shelters for B3 waste.

This study was undertaken to assess the constraints of community participation on domestic solid waste management activities in sodo city, Ethiopia. Both qualitative and quantitative data were collected from primary and secondary sources. The primary data were collected from 204 households who were randomly selected from four kebeles (Fana, Gebeya, Gido and Selame) of wolayita-sodo city. The primary data were gathered through survey questionnaire, key informant interview, focus group discussion, and field observation. The secondary data were collected from central statistics authority, city municipality, published and unpublished sources. The collected data were analyzed by using descriptive statistics and binary logistic regression model. The result shows that participation of communities on domestic solid waste management was low. The result from binary logistic regression model revealed that the probability of household participation on domestic solid waste management was positively and significantly constrained by educational level of households, household income, and household access to main road, small-scale enterprise service coverage and supply of waste facility. On the other hand, sex of household head and marital statuses were negatively and significantly constrained the probability of household participations on domestic solid waste management. As a result, widening the horizon of education and training, expanding small-scale enterprise service coverage, supply of waste facility and provision of road infrastructure within the community was suggested to reduce constraints of community participation on domestic solid waste management.

The present study quantified environmental impacts of the Rawalpindi Waste Management Company (RWMC) value chain in Pakistan for three consecutive years (2015–2018) using a cradle-to-grave life cycle assessment (LCA) approach. Energy potential from municipal solid wastes (MSW) was also predicted till the year 2050. Based on a functional unit of 1.0 tonne of MSW, the study analyzed inputs and outputs data through SimaPro v.8.3 applying CML 2000 methodology and cumulative exergy demand indicator (CExD). LCA revealed that operational activities of RWMC mainly contributed to marine aquatic ecotoxicity, i.e. 8962.83 kg1,4-DBeq t−1 MSW, indicating long-range transport of petrogenic hydrocarbons from the company’s fleet gasoline combustion. Similarly, human toxicity potential, global warming potential and freshwater aquatic ecotoxicity potential were also found to be significant, i.e. 18.14 kg1,4-DBeq t−1 MSW, 15.79 kgCO2eq t−1 MSW and 6.22 kg1,4-DBeq t−1 MSW, respectively. The CExD showed that company activities consumed 827.14 MJ t−1 MSW exergy from nature, and gasoline used in MSW transport was the most exergy-intensive process, using 634.47 MJ exergy per tonne MSW disposed of. Projections for energy generation potential up to the year 2050 showed that MSW of Rawalpindi city will have the potential to produce 3901 megawatt of energy to fulfill the energy needs of the country. Possible stratagems to reduce environmental impacts from the municipal solid waste management (MSWM) value chain of RWMC include curtailing dependency on petrogenic and fossil fuels in mobile sources, optimization of waste collection methods and dumping routes, inclining attention toward suitable wastes-to-energy conversion technology and opting for a holistic approach of MSWM in Pakistan.

Full textAbstract:
This study aims to present waste characterisation, solid waste management practice and analyse the challenges in the solid waste management system in the tourism destination of Hoi An City, Vietnam. The sampling and questionnaire surveys were conducted for measuring characterisation and management practice of solid waste. A material flow analysis method was used for analysing the waste flow. The results show that the tourism destination generated daily around 15080 kg t of waste, in which the significant proportions come from restaurants (46%), hotels (22%) and households (13%). The feature of the waste composition is high rates of kitchen waste (46.8%), tissue (11.54%) and recyclable materials (12.58%), which result in high moisture (46.79%) and a low heating value (16,866 kJ kg-1) of waste. Also, solid waste management practices were evasively implemented by stakeholders with low rates and efficiency. Furthermore, a substantial gap of the solid waste management system is the confusion in waste collection activities, which is shown by the overload of waste in street bins and the financial loss for the solid waste management system owing to the non-compliance with collection regulation of stakeholders. Also, the mixing of waste by collection crews after separation at sources, the in-appropriation of collection time and manner are the dark points of the solid waste management system that may be causes of the non-cooperation of stakeholders. These gaps and confusion in the solid waste management system are the significant challenges in the improvement of the solid waste management system in the tourism destination toward sustainability.

Managing solid waste is becoming a rather challenging task in remote areas, including the Mt. Everest region in Nepal, due to its cold climate, complex topography, and extreme environmental factors. Using published and unpublished literature and personal communications to key informants, this paper analyzes the situation of solid waste management in the Everest region as it relates to increasing tourism and possible environmental implications in the region. The study revealed that combined efforts from people of all levels associated with the mountain region would create a circular waste management system. The paper also reports the existing practices and planned activities for the essential process such as source segregation of waste, collection, use of material recovery facility, and recycling which could lead to sustainable solid waste management in the Everest region and beyond with similar context.

Full textAbstract:
Municipal solid waste has always been an undesirable asset in society, and its generation grows every year. Inadequate waste disposal may cause many problems, either by the contamination of the environment or by its capacity to serve as a vector for a series of pathogenic elements. The COVID-19 pandemic drew the world’s attention to these challenges and made it clear how they impact society in an unprecedented way. The higher amount of waste and safety supplies discarded, such as masks and facial shields, require an analysis of the current situation of solid waste management along with solutions to increase the capacity for resource recovery. Methods of treating, collecting, transporting, and disposing of municipal solid waste must be integrated with the other levels of the waste hierarchy (prevention, reuse and preparing for reuse, recycling, other recovery (including energy recovery), and disposal). The scientific literature on this subject was verified in this paper, serving as a subsidy for the implementation of possible processes to be used in companies in the area of basic sanitation and city halls, which can benefit from investments that will incur in the generation of products of added value, creating a new link in its business chain. The production and application of integrated municipal solid waste management systems, including energy recovery from refuse derived fuel, can reduce the volume and expenses of municipal administrations with inadequate waste disposal in landfills and promote more sustainable practices in the circular economy scenario. Therefore, this paper sought to highlight the main activities related to municipal solid waste management with an aim to energy recovery.

Full textAbstract:
Better solid waste management (SWM) is a critical need for many industrialising cities in the world, with institutional and financial issues critical to improving management. Great progress was made from 1970–2000 in estimating the costs for healthcare in industrialising cities, while to date very little progress has been made in improving cost function analyses on SWM. The similarities between the two sectors are strong, and the history of healthcare cost function analysis used to elucidate a pathway to improved cost function analyses for industrialising cities. The following cost function issues are explored: economy of scale, marginal cost analysis, cost function analysis, economies of scope, relationship between size of service provider and costs, accounting for outpatient and informal sector activities, input prices and ownership and control. The recommendation is that future work on SWM cost analysis should prioritise (1) analysis of which variables need to be included or can be excluded in cost function analysis, (2) use of cost functions to analyse questions related to service provision and (3) collection of more and more appropriate data to allow development of cost functions analysis methods specifically suited to SWM in industrialising cities.

Full textAbstract:
The widespread generation of, ever increasing volumes of and the sustainable management of solid wastes are global issues of great concern. Due to wide variations in composition and associated complexities, significant efforts are required for their collection, processing and environmentally safe disposal in a cost effective manner. An overview of solid wastes is presented in this article with a specific focus on municipal solid wastes and industrial waste from the iron/steelmaking and aluminium industries. Key waste issues such as its sources, compositions, volumes, the factors affecting waste generation and waste processing are first discussed, followed by a further discussion regarding recycling, resource recovery, disposal and the associated environmental impacts. In a special case study, waste generation and management in Chile is presented in greater detail. Detailed information is provided on government initiatives and legislation for integrated solid waste management and its movement towards a circular economy. Measures include regulations on waste management framework which concerns the transboundary movements of hazardous wastes, persistent organic pollutants, the closure of mining activities and installations and restrictions on plastics disposal. With Chile being world’s largest producer of copper, significant efforts for mining waste management, its infrastructure and procedures are being put in place to reduce the environmental impact of the mining sector and its associated waste generation.
