Access to information about Solid Waste Management (SWM) is critical in changing the negative attitudes of urban residents towards proper handling of waste. This paper focuses on the influence of access to information about SWM on proper solid waste handling by residents in Eldoret Municipality. A survey design was adopted, 170 households were randomly selected, questionnaire and observations u...

At present in Germany there are 61 plants for Mechanical(-Biological) Treatment (M(B)T) of residual wastes with a total capacity of about 6.4 million tons per year. They can be classified in four process concepts: material stream separation, mechanical-biological stabilization (with a biological drying process), mechanical-physical stabilization (with a thermal drying process) and mechanical(-b...

This paper provides an overview of the trend of generation, composition, and management of municipal solid waste, and estimates the carbon emissions arising from municipal solid waste management in Beijing. The correlation analysis conducted shows that the generation of municipal solid waste in Beijing has been growing steadily, showing high correlations (r > 0.9) to the total GDP, per capita i...

Large volumes of ash from combustion of municipal solid waste are produced and most of it is landfilled. As this type of ash contains significant amounts of metal compounds the landfilling strategy is not optimal when considered from a resource conservation perspective. A better situation would be created if metals were recovered from the ash. In the present study leaching and solvent extractio...

A novel polymeric sorbent has been synthesized by graft copolymerization of crosslinked polyvinyl alcohol with malic acid, and characterized by FTIR, TGA and swelling studies. A suitable and interesting method has been developed for the extraction and separation of lead ion with the graft copolymer. The lead ion uptake capacity of the polymer has been evaluated vis-a-vis varying pH and metal io...

Activated carbon is an adsorbent in the separation and purification industries. The adsorption capacity of activated carbon depends on porosity and its surface chemistry. In this review the production of activation carbon from a large number of abundant and low-cost materials and agricultural waste such as Camellia oleifera shell, bamboo, cherry stones, waste tea, and Paulownia flower are discu...
