BACKGROUND Medical establishment such as hospitals and research institutes generate sizable amount of hazardous waste. Health care workers, patients are at risk of acquiring infection from sharps and contamination of environment with multiple drug resistant microorganisms if wastes are not properly managed. OBJECTIVES To characterize types and evaluate waste disposal techniques employed in th...

background: the municipal solid wastes (msws) are disposed in open dumps, which have no leachate collection and removal system, in the caspian region of iran. leachate readily reaches the nearby water resources such as streams, rivers, lakes, and sea. therefore, understanding the quality and quantity of open dump leachate is vital to the proper treatment of leachate. methods: the leachate sampl...

management of solid waste (flyash) has attained an apparent scenario for scientific & strategic concern in india due to large-scale dependence on coal-based thermal power plants. waste utilization as the best option of pollution-prevention and disaster risk strategy has been worked out during previous decades to open doors for flyash utilization on various sectors of developmental and manuf...

this paper presents future trends of urban wastes and their impacts on the environment of african cities using plausible mitigation scenarios. to accomplish this, an integrated dynamic model for urban waste flows was developed, tested, calibrated and validated. its parameter sensitivity was analyzed. using population projection up to 2052 with different levels of technological implementation, p...

a new, local agro-industrial waste was valorized by chemical treatment and tested for its ability to remove cationic dye from aqueous solution. tendu (diospyros melanoxylon) leaves refuse, a solid waste from bidi industry which caused disposal problem, was studied as a biosorbent. raw tendu waste (tlr), along with sulfuric acid carbonized tendu waste (tlr-cm) and tendu waste treated with dilute...

In developing Asian countries, the municipal cooperations are unable to handle the increasing amount of municipal solid waste, which into the uncollected waste being spread on roads and in other public areas leading to tremendous pollution and destruction of land and negative impact on human health. Generation of municipal solid waste increases with the rapid urbanization and accelerated econom...

-----------------------------------------------------------ABSTRACT---------------------------------------------------------To plan effectively and successfully manage the solid wastes, proper quantification and characterization are essential. Recovery from solid waste is an important aspect where as disposal is only the final option. Recovery of methane from landfills is rarely practiced in In...

A comprehensive study of the generation and characterization of municipal solid waste is essential to the longterm efficient and economical planning for solid waste management. The aim of this study was to quantify and analyze the solid waste generated in the city of Ensenada, Mexico, and to use this data in a project that will generate energy through methane gas production. Ensenada’s per capi...

This paper provides a broad overview of recent trends in solid waste and recycling, related public policy issues, and the economics literature devoted to these topics. Public attention to solid waste and recycling has increased dramatically over the past decade both in the United States and in Europe. In response, economists have developed models to help policy makers choose the efficient mix o...
