Life cycle assessment (LCA) has been used extensively within the recent decade to evaluate the environmental performance of thermal Waste-to-Energy (WtE) technologies: incineration, co-combustion, pyrolysis and gasification. A critical review was carried out involving 250 individual case-studies published in 136 peer-reviewed journal articles within 1995 and 2013. The studies were evaluated wit...

This investigation has been undertaken to better understand pollutant formation in Waste-to-Energy (WTE) systems by using Computation Fluid Dynamics (CFD). An above-grate gas phase only model was built and calculated in FLUENTTM with the intent of specifically studying the factors that influence the formation of NOx. Results are shown for a typical reciprocating-grate WTE boiler operating on mu...

Increasing population and changing life style has led to the dramatic increase in waste generation. It has been estimated that global generation of post recycling MSW in populated centers amounts about 1.2 billion ton per year. India alone produces about 90 million tons of MSW per year. If this large amount of waste can be converted into energy then the problem of its management and energy cris...

Many countries are at a crucial junction on the way to tackling the ever-increasing waste problem. A fresh look at their strategic options suggests that processes such as waste-to-energy (WTE) could play a more important role. This neglected energy source could also have a major impact on power generation at a local level. It would resolve some of the potential future electricity generation pro...

The study aimed to analyze potential environmental burdens of different waste-to-energy technologies through LCA model. LCA model is developed by SimaPro software by considering Ecoindicator 99 method. Landfill, Incineration, Pyrolysis-Gasification and Anaerobic Digestion are analyzed by considering emission to the atmosphere per unit electricity generation. Results show that, Landfill and Inci...

Despite increased efforts to prevent, reduce, reuse and recycle, the appropriate management of municipal solid waste (MSW) remains a major environmental issue. Currently, Waste-to-Energy (WTE) facilities produce clean renewable energy through the combustion of municipal solid waste in specially designed power plants equipped with the most state-of-the-art pollution control equipment. Neverthele...

The management of solid waste has become a major problem and budget item of municipalities, especially in rapidly developing cities. The only alternatives for post-recycling waste are sanitary landfills, which require large tracts of land, and waste-to-energy (WTE) plants which are costly to build; an additional problem in the developing world is the high (>50%) organic and moisture content of ...
