This paper examines the impact of two popular solid waste programs on the percent recycled of several different materials found in the residential solid waste stream. We examine a unique, national, household-level data set containing information on the percent recycled of five different materials: glass bottles, plastic bottles, aluminum, newspaper, and yard waste. We find that access to curbsi...

In many countries, informal waste pickers contribute significantly to waste management and resource efficiency by collecting, sorting, trading and sometimes even processing waste materials. These activities also provide an income opportunity for large numbers of poor people. GTZ aims to determine the factors for successful informal sector integration in solid waste management systems in order t...

The accumulation and disposal of polymer wastes including waste plastics, waste rubber, waste synthetic fibers and waste composites is a worldwide concern. Until now, there are many technical barriers in recycling polymer wastes with crosslinked structure, such as vulcanized rubber, crosslinked polyolefine and other thermoset materials. In this study, a mechanochemical approach was used to cond...

This paper reviews documented environmental effects experience from the disposal of solid waste materials in the U.S. Selected case histories are discussed that illustrate waste migration and its actual or potential effects on human or environmental health. Principal conclusions resulting from this review were: solid waste materials do migrate beyond the geometric confines of the initial placem...

In this study, the possibility of using tea production waste as a new casing material in mushroom (Agaricus bisporus) cultivation was investigated. Some physical and chemical characteristics of tea waste, fermented tea waste and a mixture of tea waste with peat were compared with that of peat casing, as were their effects on yield. The highest yield was obtained from peat casing. Using tea prod...

Epidemiologic studies are required for assessing health risks related to toxic waste exposure. Since the settings in which such studies must be performed are extremely diverse, epidemiologic approaches must be versatile. For any particular study, three fundamental requirements are to assess what toxic materials are present, understand how human exposure may occur, and objectively measure possib...

The choice of a site for high and intermediate level nuclear waste product material disposal in Jordan requires careful consideration of hydrology, hydrogeology, geological materials, seismicity, climate and other geological factors. The purpose of this paper is to explore how these factors in Jordan may affect the ultimate decision on where to site such a facility. Taking these factors into co...

Thisresearch paper is dedicated to an actual issue in Latvia and in the whole European Union – development of the secondary materials management. The goal of this paper is to research the development of the secondary materials management in Latvia as a result to point out its main positive aspects and problems. In this research paper the author regards following issues: significance of the seco...

Waste management is the collection, transportation, processing, recycling or disposal of waste materials. The term usually relates to materials produced by human activity, and is generally undertaken to reduce their effect on health; the environment or aesthetics.Human urine can be well harnessed through proper waste management method. Waste management is also carried out on human urine to redu...
