anaerobic digestion of organic solid waste (osw) from kitchen was conducted in completely stirred tank reactors (cstrs) under both mesophilic and thermophilic conditions. the lab-scale reactors were fed with the osw containing 10% of total solids (ts) at a hydraulic retention time (hrt) of 30 days (3.0-3.5 g-ts/l/d of volumetric loading rate). both mesophilic and thermophilic reactors exhibited...

Composting is clearly reported as one of the most effective technique to transform organic wastes into an interesting resource, useful to improve soil characteristics and playing a potential role in reducing greenhouse gases, due to its high content in stable organic matter (Favoino and Hogg, 2008). However, its agronomical properties are dependent on several factors, which pollutant contents b...

landfill and incineration are two common methods mostly used for disposal of huge quantities of solid wastes. the bioconversion ability of earthworms in vermicomposting process of organic waste in different types of bedding materials was investigated to produce more valuable products as an economical and effective alternate method for solid waste management. in this work organic waste (obtained...

Municipal solid waste was collected from Varanasi’s municipal solid waste dumpsite and sorted for organic fraction present in it. Current work showed the consequences of calcium hydroxide or lime digestion on organic fraction of municipal solid waste of Varanasi, India. The organic fraction of municipal solid waste sample was digested with desired amount of calcium hydroxide. The different conc...

Prediction of biodegradation processes for the organic fraction of municipal solid waste is an issue of paramount interest for efficient landfill design and management. This paper presents the results obtained from an extended field work developed in a time period of ten years. Solid waste samples from a landfill were collected at different depths in 5 holes with depth of 17 m, and analyzed in ...

Organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. Composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. An integrated approach of composting methodology was tested for municipal solid waste management. Solid waste first was composted and after 22 days, was...

The moisture retention and compression characteristics of municipal solid waste under self-weight are likened to those of an unsaturated soil. By assuming that the solid organic fraction in waste retains a relatively immobile micropore moisture and that deformation at low confining stress occurs at the expense of a relatively large macropore system, an insight into the variation of density and ...

Background and Purpose: Improper wastewater and solid waste management in rural areas could be a risk to human health and environment pollution. One percent of Iran’s rural area is connected to the wastewater collection network. Solid waste management in rural areas of Iran is mainly consisted uncontrolled dumping and open burning. The aim of this study is prioritization of wa...
