Increasing municipal solid waste (MSW) generation has become not only a major sustainability challenge and considerable financial burden for municipalities across the globe, but also an opportunity to promote circular economy, provided adequate information is made available. Data on MSW generation, characterization, management practices are prerequisites studying optimizing systems (SWMS). Howe...

Electronic  waste  or  E-waste  is  relatively  a  novel  addition  to  the  ever-growing  hazardous waste stream. It includes discarded electronic and electrical equipment. Developing countries face enormous challenges which are related to the generation and management of E-waste which are either internally generated or imported illegally; India is no exception. However, the existing managemen...

twenty four cowpea varieties were raised at niab and arri, faisalabad selected for plant height (42-136cm) days taken to 95 % flowering (62-79 days) and for diseases resistance (0.67-7 rating). infestation was maximum on it-97k-461-4, 1068-7, it-97k 1042-8 and it-98k-558-1 and was graded as susceptible. maximum grain yield was recorded in elite (649 kg/ha) and lowest grain yield was observed in...

population growth and consequently increasing waste are made concern about resources degradation. thus, municipal solid waste management (mswm) becomes a priority for experts in recent decades. to apply new technology in mswm and engineering methods is the base of determining strategies, health and environmental policies. mswm is included some factors such as waste generation, collection, trans...

Waste is a byproduct of human life. Nowadays, municipal solid waste is being produced in excessive amounts and in this way, both developing and developed countries are facing challenges regarding generation of waste. Economic development, urbanization and improved living standards in cities have contributed to increase in the amount and complexity of solid waste produced. The present stud...

Research Objective — This project focuses on the development of reliable theoretical and efficient computational descriptions of the chemistry of high-level waste simulants in highly concentrated solution and the experimental validation of this approach. It is an extension of previous work which: a) Determined the mechanism of H2 formation in waste simulants allowing quantitative prediction of ...

Municipal solid waste (MSW) characterisation across socioeconomic residents is necessary for planning sustainable solid waste management. In view of planning for Kumba municipality in the South West Region of Cameroon, three types of socioeconomic residents classified as low, medium and high income residential areas were randomly sampled. In each residential area, 32 households were sampled fol...

wear is a complicated phenomenon caused by the relative movement of two contacting surfaces compressed together by a normal force. prediction of the wear, in most cases, requires various experiments and microstructural characterization of the contacting surfaces. mathematical models based on physical concepts could provide considerable help in understanding the physical behavior and hence the p...
