Anaerobic digestion (AD) is a process by which microorganisms break down biodegradable material in the absence of oxygen. Anaerobic digestion can be used to treat various organic wastes and recover bio-energy in the form of biogas, which consists mainly of CH4 and CO2. A great option for improving yields of anaerobic digestion of solid wastes is the co-digestion of multiple substrates. Numerous...

Landfill Gas to Energy This research investigates the utilization of landfill gas, an abundant waste product, by reforming it to syngas that can be converted to liquid fuels using Fischer Tropsch or to a H2 rich stream using water-gas shift. 65% of the 413 million tons of municipal solid waste (MSW) generated per year in the United States is landfilled, and 67% of the landfilled MSW is composed...

Knowledge management (KM) is a key factor to increase effectiveness of management system. There have been researches of KM on many environmental services. Unfortunately, only a few researches have focused on sustainable service for Municipal Solid Waste (MSW). There are evidences of ineffective waste management causing socio-economic and environmental problems, especially in urban areas of deve...

This article examines how RFID (radio frequency identification) is poised to help transform the way we handle our trash our MSW (Municipal Solid Waste). We provide an overview showing that trash trends in the United States are not good, as modern life has meant increasing volumes of trash that can be disposed of in fewer and fewer landfills. We examine how RFID can be employed in the MSW area t...

The environmental impacts of municipal solid waste (MSW) management have been highlighted in China, due to the continually increasing amount of MSW being generated and the limited capacity of waste treatment facilities. Of particular interest is greenhouse gas (GHG) mitigation, aided by the Kyoto Mechanisms. China is an important case study for this global issue; however, an analysis of the ent...

In January 1997, a pilot-scale project to assess the feasibility of in silu aerobic bioreduction of municipal solid waste was initiated at the Live Oak Landfill, located near Atlanta, Georgia The high costs (money, regulatory hurdles, societal objections) of developing new landfills are making fccovery and reuse of existing landfill space an increasingly attractive alternative. Onc bf the first...

We model a municipal solid waste (MSW)-to-ethanol facility that employs dilute acid hydrolysis and gravity pressure vessel technology and estimate life cycle energy use and air emissions. We compare our results, assuming the ethanol is utilized as E85 (blended with 15% gasoline) in a light-duty vehicle, with extant life cycle assessments of gasoline, corn-ethanol, and energy crop-cellulosic-eth...

Carbon dioxide, methane and nitrous oxide are the major Greenhouse Gases (GHG’s), which emit from landfill areas and contribute significantly to global warming. Moreover, that the global warming potential of methane is 21 times higher than that of carbon dioxide and it has highest generation (60%) than other gases. Therefore, there is immense concern for its abatement or utilization from landfi...

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:...
