the province of bushehr is located in southern area of iran and north of persian gulf. solid waste management in bushehr’s villages was the aim of this research. for the sake of this study, 21 villages scattered all over the province were selected. field studies showed that about 646 grams of residential solid waste per capita is generated in selected villages every day. there are 322 shops i...

One of the challenges faced by waste management authorities is determining the amount of waste generated by households in order to establish waste management systems, as well as trying to charge rates compatible with the principle applied worldwide, and design a fair payment system for households according to the amount of residential solid waste (RSW) they generate. The goal of this research w...

The current estimates and glass formulation efforts have been conservative in terms of achievable waste loadings. These formulations have been specified to ensure that the glasses are homogenous, contain essentially no crystalline phases, are processable in joule-heated, ceramic-lined melters and meet Hanford Tank Waste Treatment and Immobilization Plant (WTP) Contract terms. The WTP’s overall ...

This paper examines the impact of the seed source on methanogenic abundance and overall performance of thermophilic anaerobic digesters treating the source-sorted organic fraction of municipal solid waste (SS-OFMSW). Two digesters were started up with different seed mixes and operated for 250 days until steady-state was reached. Quantitative Polymerase Chain Reaction (QPCR) was used to determin...

Waste-to-energy (WtE) facilities have been established worldwide as a sustainable method for the disposal of residual waste. In the present study the following competing WtE systems were compared: (1) municipal solid waste incinerators (MSWIs) with energy recovery; (2) co-incineration of waste in old lignite or coal-fired power plants; (3) substitute [refuse-derived fuel (RDF)] incinerators wit...

Landfills are the final repository for most of the discarded material from human society and its "built environments." Microorganisms subsequently degrade this discarded material in the landfill, releasing gases (largely CH4 and CO2) and a complex mixture of soluble chemical compounds in leachate. Characterization of "landfill microbiomes" and their comparison across several landfills should al...
