Municipal solid waste(MSW)management is the most challenging environmental issue in developing countries around global municipalities.In mountainous regions,very few studies can be found and the availability of limited data,because waste management poses different challenges due to different climate,topography,and geographical conditions.This study has been conducted in three urban areas of the Kashmir region(i.e.,Baramulla,Kupwara,and Bandipora)in the western Himalayas.Presently,waste management is underdeveloped and openly dumped in an unscientific manner near to the rivers,streams,and lakes,which increases the threat of contamination to ground and surface water,respectively.The present study aimed to analyze the current scenario of the MSW management system and its waste generation rates.The Physio-chemical characterization of municipal solid waste was carried out by using a quarter and cone method.Proximate analysis of samples was performed by using muffle furnace and bomb calorimeter for chemical analysis,respectively.The findings of the MSW generation of urban areas of Kashmir were approximately 181.43 Mt/day(93.73 Mt/day in Baramulla,57.46 Mt/day in Kupwara,and 30.27 Mt/day in Bandipora),respectively.Further,the findings of MSW showed high organic waste between(10.3%-68.5%),followed by recyclable waste(12.3%-15.30%),and inert waste(8.27%-9.10%),respectively.Also,the chemical characterization results showed average moisture content varying between(47.6%-52.40%)with the lower calorific values of(1017-1175.6 kcal/kg)in the areas mentioned earlier.In conclusion,alternative treatment methods were proposed,for instance,compositing,biomethane plants,the installation of recycling plants,and upgrading the existing dumping sites to sanitary-engineered landfills.

Upon the realization that urban areas can only achieve sustainable Solid waste management systems through an interplay of partnerships and stakeholders,developing countries have geared themselves towards the privatization of waste management services in efforts to reduce costs and improve efficiency.Lobatse,a town located in the south of Botswana,faces the increasing challenges of poor waste management due to the lack of finances and resources available to the Lobatse Town Council,which hinders efforts towards a sustainable waste management system.This has negative implications for public health and the environment,as a result of solid waste pollution from littering and the illegal dumping of waste.This work examines the current state of Solid waste management and its challenges in Lobatse,within the context of the interplay between public and private Solid waste management.The study aims to perform a social exploration of the efficiency of waste management services,considering the political economy and households’perceptions towards these services.Key stakeholders were interviewed and a social survey of 222 households was conducted to generate primary data.The findings indicate that the involvement of the private sector yielded positive outcomes,as it increased the solid waste collection frequency and improved the quality of the waste management service.Most of the stakeholders were in favor of privatization,and the households were satisfied and willing to contribute towards the cost recovery of Solid waste management.It is,therefore,recommended to promote and establish a private-public-community partnership in the town to improve the quality of the waste management system.

This investigation is focused on conducting a thorough analysis of Municipal Solid waste management (MSWM). MSWM encompasses a range of interdisciplinary measures that govern the various stages involved in managing unwanted or non-utilizable solid materials, commonly known as rubbish, trash, junk, refuse, and garbage. These stages include generation, storage, collection, recycling, transportation, handling, disposal, and monitoring. The waste materials mentioned in this context exhibit a wide range of items, such as organic waste from food and vegetables, paper, plastic, polyethylene, iron, tin cans, deceased animals, byproducts from demolition activities, manure, and various other discarded materials. This study aims to provide insights into the possibilities of enhancing Solid waste management in the Farmgate area of Dhaka North City Corporation (DNCC). To accomplish this objective, the research examines the conventional waste management methods employed in this area. It conducts extensive field surveys, collecting valuable data through interviews with local residents and key individuals involved in waste management, such as waste collectors, dealers, intermediate dealers, recyclers, and shopkeepers. The results indicate that significant amounts of distinct waste categories are produced daily. These include food and vegetable waste, which amount to 52.1 tons/day;polythene and plastic, which total 4.5 tons/day;metal and tin-can waste, which amounts to 1.4 tons/day;and paper waste, which totals 5.9 tons/day. This study highlights the significance of promoting environmental consciousness to effectively shape the attitudes of urban residents toward waste disposal and management. It emphasizes the need for collaboration between authorities and researchers to improve the current waste management system.

作者： Simon Adom Wisdom Takramah Mavis Pearl Kwabla Margaret Kweku School of Public Health University of Health and Allied Sciences Ho Ghana

Solid waste management has become the greatest public health problem facing many urban and semi-urban areas in Ghana. Great wealth can be generated from wastes if managed effectively but also has high probability of causing serious health and environmental problems if not effectively managed. The study sought to determine factors militating against domestic Solid waste management in Hohoe, possible ways of curbing them and also to assess the methods of domestic Solid waste management. This study used descriptive cross-sectional survey and structured questionnaire to obtain the required information from respondents. A total number of 403 respondents were recruited into the study. The data collected were entered and analyzed using Statistical Package for Social Sciences version 20. The relationships between socio-demographic characteristics of the respondents and their use or non-use of apt domestic solid waste disposal methods were examined using chi-square analysis. The study found that 44% of respondents disposed domestic waste into central skip over dustbins. Spilled over of skip over dustbin has caused 8% of respondents to practice open burning. 7% dumped on undeveloped building plots, 5% dumped elsewhere, and 3% dumped into the river course. About 78% of respondents reported that mobilization of cleanups was irregular. The result from the study also showed a statistical significant association between practice of domestic Solid waste management and religion [χ2 (2, 403) = 60.9484, p α = 5%]. About 96% of Christians practiced good methods of domestic Solid waste management compared to 4% of Muslims. The findings painted a gloomy picture of poor domestic Solid waste management practice among the respondents in the study communities.
