Generation of municipal solid waste (MSW) continues to rise, which leads to loss of resources and increased environmental risks. The conventional treatment of wastes such as open dumping and land filling cause environmental degradation. Since the major fraction of wastes generated in India is organic wastes, composting has emerged as one of the best methods for treatment of wastes. Composting, ...

Backyard burning of household waste in barrels is a common waste disposal practice for which pollutant emissions have not been well characterized. This study measured the emissions of several pollutants, including polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/PCDFs), from burning mixtures designed to simulate waste generated by a “recycling” and a “nonrecycling” fam...

In a column experiment with horizontal permeable barriers, the effects of a biodegradable chelator-nitrilotriacetic acid (NTA) on the uptake of heavy metals from municipal solid waste (MSW) compost by Festuca arundinacea and metal leaching were investigated. The use of NTA was effective in increasing Cu, Pb, and Zn uptakes in shoots of two crops of F. arundinacea. In columns with barriers and t...

The generation of municipal solid waste is increasing year by year and there are many options for handling and disposing of these wastes. Currently in United States land disposal is the most common practice to deal with municipal solid wastes. The evolution of waste generation, and increase in population suggest composting as a future alternative. Since municipal solid waste comprises of a high...

wheat flour is known as the best nutrients supplier for human. in this research, the effects of combined application of nitrogen fertilizer, farmyard manure (fym), sewage sludge and municipal waste compost on nutrients concentrations of wheat flour (triticum aestivum cv. alvand) were studied in a randomized complete blocks design with 15 treatments and three replicates in agricultural research ...

this study was done with the aim of investigating the kinetics of available phosphorus changes in treated soils with municipal solid waste compost, fertilizer and the mixture of these in two levels of first and second percent in eight calcareous soil samples and in a period of zero to 3600 hours in incubation conditions (fc moisture and 250c). the results showed that with time increasing, extra...

Saline soil was amended with 13.3 and 26.6 g kg of Municipal Solid Waste (MSW) compost or sewage sludge, and arylsulphatase (ARY), phosphatase (PHO), dehydrogenase (DEH), β-glucosidase (β-GLU), urease (URE) and catalase (CAT) activities as well as physical-chemical properties were determined after 70 day of incubation under laboratory conditions. MSW compost and sewage sludge significantly impr...

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...

A pilot study was conducted to assess the feasibility of composting of source separated organic matter of municipal solid waste (MSW) generated in low, middle and high income areas of Karachi city with a population over 14 million. Results of MSW analysis indicate the presence of high percentage of biodegradable organic matter (71-74%), acceptable moisture content (40-50%) and C/N ratio (38-40:...
