Waste is a continually growing problem at global and regional as well local levels. Solid wastes arise from human animal activities that are normally discarded useless or unwanted. In other words, solid may be defined the organic inorganic waste materials produced by various of society which have lost their value to first user. As result rapid increase in production consumption, urban rejects g...

In developing countries, little information is available about solid-waste characteristics, determinants for adoption and performance-evaluation of municipal-waste management systems in Municipals. This study aimed: to characterize the municipal solid-wastes, collection, dumping evaluate efficiency reliability Municipal system. A total 200 households were randomly sampled interviewed. Data was ...

Iran is a developing country with a population of over 80 million. The total daily MSWs production in Iran is about 50 million kg. Most of the MSWs in this country is being disposed of in the landfills. Some of the landfills are located in the urban area or near to sea, river, and forest. In this regard, the management of MSWS becomes a concern in Iran. One solution to manage MSWs and mitigate ...

Organic wastes under consideration are of natural origin that possess biochemical characteristics ensuring rapid microbial decomposition at relatively normal operating conditions. When considering the organic waste treatment we have generally in mind organic mineralization, biological stabilisation and detoxification of pollutants. Most common organic wastes contain compounds that are mainly we...

The increasing awareness that there are limits to the availability of nonrenewable resources, as well as that there are limits to the biosphere’s ability to absorb wastes, are at the basis of the growing interest about Microbial Fuel Cells (MFCs) technology, with particular regards to their application to wastes treatment. MFCs, in fact, couple the direct electric power production to the degrad...

Sludge dewatering and treatment may cost as much as the wastewater treatment. Usually large proportion of the pollutants in wastewater is organic. They are attacked by saprophytic microorganisms, i.e. organisms that feed upon dead organic matter. Activity of organisms causes decomposition of organic matter and destroys them, where the bacteria convert the organic matter or other constituents in...

agaricus bisporus is the most important industrially cultivated edible mushroom. using organic wastes as substrate for cultivation of edible mushroom can provide a perfect solution for disposal of these waste materials and is part of the world's food requirements .in this study to investigate the usability of various organic wastes as growing bed for button mushroom, four types of substrat...

landfilling is an ultimate fate of any municipal solid waste management system, and it is a no alternative choice for disposal of municipal solid waste. the major environmental concerns associated with landfilling of wastes are related to the leachate generation and eventual discharge of leachate into the environment. leachate quality is formed due to aerobic and anaerobic processes taking plac...

This paper compares life-cycle greenhouse gas GHG emissions from two municipal solid waste MSW management options, municipal waste combustion, and landfilling, using a U.S. EPA life-cycle assessment LCA model, the MSW Decision Support Tool. Unlike previously reported LCAs, key combustion model inputs—total MSW carbon content and its biogenic/fossil split—are determined not from MSW composition ...
