Ecofriendly approach of urban solid waste management: a case study of Jalgaon city, Maharashtra
In India, the traditional methods are used for urban solid waste management. These practices are associated with degradation of the urban environment hence, an environmentally sound garbage management system is required for the urban waste management. The concept of waste minimization needs to be adopted in such systems. It is possible to implement certain corrective measures at collection, storage, transport and disposal of urban solid waste to minimize the adverse impacts on the environment. The investigations are emphasized on generation, characterization and ecofriendly disposal of solid waste generated in Jalgaon city, Maharashtra. In the present study the waste generation at source was studied in the various income groups of the city. The per capita waste generation was studied by sampling the waste directly from the source of generation. The study reveals that the waste generation is large in the high-income group followed by middle and low-income group public. Further the physicochemical characterization of the waste was also studied. The data generated will help to develop environmentally sound and economically feasible solid waste management system for the city.
Solid waste management associated with the development of 3R initiatives: case study in major urban areas of Vietnam
The purpose of this study is to describe the application and progress of the Reduce-Reuse-Recycle (3R) initiative and its gradual implementation and development in solid waste management in Vietnam through the study of the municipal solid waste management (MSWM) systems of eight major urban cities and provinces. The resulting survey and studies showed that there are big challenges for MSWM in the study areas due to the absence of an appropriate master plan for MSWM; there is a clear need to set up indicators for waste reduction and greenhouse gas emission reduction from waste generatorsand enterprises involved in MSWM, especially in terms of using 3R activities in the management of industrial waste. The strength and organic combination of institutional frameworks, support measures, and technologies for 3R promotion need to be applied as soon as possible in order to implement MSWM practices using more effective measures; in particular, a reduction in the amount of hazardous substances discarded and improvements in the handling of hazardous waste are required.
Household Solid Waste Generation in Urban Pakistan: A Case Study OF Rawalpindi
Nowhere else in Pakistan is the urban rot more pronounced than in the waste-littered streets. Apart from being an eyesore, ill-managed solid waste in Pakistan is one of the primary causes of health and environmental problems, which costs the state and individual households hundreds of millions of rupees in healthcare costs and lost productivity.
This paper focuses on the determinants of household solid waste generation in Rawalpindi Cantonment. Relying on a survey of economically-differentiated 118 households in six urban neighbourhoods, this paper has found substantial differences in household waste generation rates across various income groups. As expected, high-income neighbourhood residents generated more waste than their mid- and low-income counterparts. The total waste generated by household increased with household size. However, the waste per capita declined with the increase in the household size.
The state of solid waste collection was found to be poor across all income strata. The two low-income and one mid-income neighbourhood did not have any municipal waste collection service. Fewer than 50% of the households in the high-income neighbourhood reported access to municipal solid waste collection service. The rest self-disposed household solid waste mostly in empty lots in the neighbourhood. More than 65% of the households sold recyclables to waste collecting street hawkers, while another 25% handed recyclables to domestic workers, who in turn sold recyclables in the market.

Nashik Compost Project
In Nashik Municipal Corporation area around 230 MT of solid waste is generated per day. A compost factory has been established by the corporation for converting garbage into valuable compost /manure. The garbage is collected with the help of special vehicles named“Ghantagadi”. Nashik Municipal Corporation has established a compost plant at the cost of Rs.4.61 crores from its own funds for the processing of waste. The plant is fully owned by the municipal corporation the waste collected is transported to the compost plant where it is mechanically segregated and processed to produce fine quality compost. The garbage collected from the city contains about 40% non-biodegradable material, which cannot be converted into compost is transported to the sanitary landfill site developed near the compost plant. The compost meets all the chemical parameters and is helpful to the farmers, especially the grape growers in and around Nashik. The plant is operated on aerobic microbial composting method. Nashik Corporation is operating the plant in one shift. Cost of production of one MT of compost manure is Rs.1700.
Jordan: Aman Landfill Gas Project
Collaboration between the Greater Amman Municipality (GAM) and the World Bank in municipal solid waste disposal constitutes an important step towards a greener society, through the implementation of the first commercial-scale project converting landfill gas to energy at the Ghabawi Sanitary Landfill site, located 40 kilometers east of the center of Amman, Jordan and is owned and operated by GAM. This is an innovative solid waste management project that will contribute not only to the improvement of solid waste management in greater Amman, but also offers Amman the opportunity to mobilize additional and unconventional revenues and to mitigate negative environmental effects at both the local and global level. One of the main component objectives of this project is to avoid methane (a greenhouse gas) emissions from the Ghabawi Sanitary Landfill by installing landfill gas collection and electricity generation plant. This will introduce environmentally friendly technology, and generating electricity from LFG. The total estimated emission reduction from the project during the first crediting period (7 years) is estimated at 1,519,963 tons CO2e for the period 2009 to 2015.
Solid waste collection systems in developing urban areas of South Africa: an overview and case study
Experience with appropriate collection systems for urban and peri-urban areas of developing countries is accumulating. Nonetheless, the primary lesson learned from studying such systems is that collection systems must be designed to accommodate the particular conditions of the community. This paper reflects on international experience with such collection systems and examines their relevance to South Africa. A case study is presented of designing a solid waste collection system for the Winterveld, Bophuthatswana, including a community survey, a waste composition study, and exploration of resource recovery options. Detailed data from the case study show that, even within one country, solid waste collection systems are not automatically transferable from one community to another. Particular recommendations for the South African situation are given.

The business model of solid waste management in Sweden- A case study of two municipally owned companies
This describes the business model of municipally owned MSW companies in Sweden. A comparative study of two of these companies shows that they combine three types of activities: public service activities that collect solid waste from household, commercial establishment and industry; processing activities that transform this waste; and marketing activities that enable products and recycled material to re-enter the economy. The historical success of the two companies rests on their ability to create value by combining these three distinct yet mutually dependent types of activities. However, an ongoing legal controversy may develop into a treat to this business model and to the entire organization of Swedish waste management.
Rural waste management in a south Indian village — a case study
A micro-level study was carried out in a typical south Indian village to assess the quantity and type of wastes generated and its present mode of management. This information was used to identify the appropriate technologies which could enhance the value of the waste produced and, at the same time, improve the economic conditions of rural people. The study indicated that nearly 2364 tons of rural wastes in the form of crop residues, animal manure and human excreta are produced annually in the village with a population of 510. About 77% of the waste generated in the village was used as domestic fuel, animal fodder and organic fertilizer for crop production. The rest (23%) was left out in open fields for natural decomposition. The energy balance sheet of the village indicated that the present consumption of biomass resources was 50% less than that actually required for various domestic and agricultural applications. Anaerobic digestion of animal manure and human excreta produced in the village could yield 82% of the domestic energy required besides enriching the waste by 3–4 times as compared to conventional storage on the ground. If the traditional mud chulha (stove) were replaced by an improved chulha, each family unit could reduce their annual biomass (fire wood) consumption by about 2/3. Commercializing the utilization of coconut and paddy biomass using the village's man-power and facilities could increase the rural family income several fold.
