the exponential growth of urbanization leads to increase in severity of environmental problemsespecially assonated with disposal of solid waste. with considering the increasing rate of solid waste generation in urban area, the problem of availability of space required to dispose it off is become a concern for planners and administrators of urban local bodies (ulb). in order to cope up with the ...

States are often seen as policy laboratories where innovations are tried that may later be adopted by other states or the federal government. Engendering such experiments may, however, promote spillovers on other states. We analyze several of New York State's policy initiatives from the 1980s that were intended to influence the selection of waste management technologies by hazardous waste gener...

Long term methane emissions from landfill sites are often predicted by first-order decay (FOD) models, in which the default coefficients of the methane generation potential and the methane generation rate given by the Intergovernmental Panel on Climate Change (IPCC) are usually used. However, previous studies have demonstrated the large uncertainty in these coefficients because they are derived...

This paper represents a detailed assessment on raw material waste generation of a semi-automated powder filling and packing process by applying certain quality tools such as Pareto Analysis and Fishbone Diagram. The aim of this study is to identify the sources or categories of raw material waste and analyse its underlying causes. Waste generation is an unavoidable incident in any production pro...

Heat is a primary byproduct of landfilling of municipal solid waste. Long-term elevated temperatures have been reported for MSW landfills under different operational conditions and climatic regions around the world. A conceptual framework is presented for management of the heat generated in MSW landfills. Three main strategies are outlined: extraction, regulation, and supplementation. Heat extr...

BACKGROUND Healthcare waste management options are varying in Ethiopia. One of the first critical steps in the process of developing a reliable waste management plan requires a widespread understanding of the amount and the management system. This study aimed to assess the health care waste generation rate and its management system in some selected hospitals located in Addis Ababa, Ethiopia. ...

Egypt is well-known in the world not only for its old heritage but also for its valued presence in superior quality of textiles. However, the textile industry is both energy intensive and highly polluting. The production of textiles often requires high levels of water consumption and emits large quantities of pollutants to the environment. Therefore, it is very important to minimize its impact ...

BACKGROUND Healthcare wastes are hazardous organic and inorganic wastes. The waste disposal management in Addis Ababa city is seen unscientific manner. The waste management practice in the health facilities are poor and need improvement. This study will help different organizations, stakeholders and policy makers to correct and improve the existing situation of healthcare waste legislation and ...

Municipal solid waste (MSW) is the natural result of human activities. MSW generation modeling is major significant in municipal solid waste management system planning. Predicting the amount of generated waste is difficult task because it is affect by various parameters. In this research, Artificial Neural Network (ANN) was trained and tested to weekly waste generation (WWG) model in Sari’s cit...

When many people work in organized institutions or enterprises, those institutions or enterprises become big meeting places that also have energy, water and resources necessities. One of these necessities is the correct management of the waste that is daily produced by these communities. Universities are a good example of institution where every day a great amount of people go to work or to stu...
