conclusions based on the findings obtained, the rate of total waste generation in the amol hospital is similar in range to that of other iranian hospitals, however, the hazardous fraction of this waste was high in comparison to other previous studies, and this is probably due to improper separation and management of the waste materials. results based on this study’s findings the average rate of...

In this paper we overview and describe the characteristics of various types of RF plasma system, which are used for different applications such as: powder processing; plasma sintering; plasma sterilization; waste treatment; element separation and nano-powder synthesis.

Fe3O4-PEDOT core-shell nanoparticles were fabricated by acid treatment mediated seeded polymerization and applied for highly efficient separation of heavy metal ions from contaminated waste water with an external magnetic field.

A source separation program for household kitchen waste has been in place in Beijing since 2010. However, the participation rate of residents is far from satisfactory. This study was carried out to identify residents' preferences based on an improved management strategy for household kitchen waste source separation. We determine the preferences of residents in an ad hoc sample, according to the...

This study compares, from an environmental point of view, different alternative scenaria for the management of municipal solid waste generated in a city of 1.000.000 citizens. Three integrated solid waste management scenaria are developed. Each of these alternatives includes the recycling of part of the recyclable MSW at the source, the collection of MSW in bins, the gathering of MSW from bins,...

Although informal waste collectors are sometimes organized in cooperatives, their working conditions remain extremely precarious and unsafe. The paper discusses the findings of action oriented, participatory qualitative research with several recycling groups in the metropolitan region of São Paulo, Brazil. During workshops with the recyclers mapping, acting, and drawing methods helped reveal he...

The proper disposal of electrical and electronic waste is currently a concern of researchers and environmental managers not only because of the large volume of such waste generated, but also because of the heavy metals and toxic substances it contains. This study analyzed printed circuit boards (PCBs) from discarded computers to determine their metal content and characterized them as solid wast...

Ma’an city faces serious administrative challenges in managing their municipal solid waste (MSW) due to the lack of adequate information of the composition and quantities of generated solid waste. The overall objective of this research is to gain more reliable information about quantities and composition of MSW stream in Ma’an city. In this work, field survey along with a separation study at wa...
