Economic feasibility of hydrogen enrichment for reducing NOx emissions from landfill gas power generation alternatives: A comparison of the levelized cost of electricity with prese...

Kornbluth, Kurt; Greenwood, Jason; Jordan, Eddie; … - In: Energy Policy 41 (2012) C, pp. 333-339

Based on recent research showing that hydrogen enrichment can lower NOx emissions from landfill gas combustion below future NOx emission control standards imposed by both federal and California state regulations, an investigation was performed to compare the levelized cost of electricity of this...

Waste heat recovery from a landfill gas-fired power plant

Gewald, Daniela; Siokos, Konstantinos; Karellas, Sotirios; … - In: Renewable and Sustainable Energy Reviews 16 (2012) 4, pp. 1779-1789

Waste treatment and management is a certain challenge especially in areas with high population density. One of the options for waste treatment is landfilling, where the amount of municipal waste also produces landfill gas through anaerobic digestion. The heating value of the landfill gas is high...

Specific applications of bio/landfill gas produced from waste organic material

Hessami, M. Akbar - In: Renewable Energy 5 (1994) 5, pp. 832-834

This paper describes three electricity and/or heat generation applications fuelled by biogas or landfill gas produced from organic waste material. It shows that aerobic and/or anaerobic treatment of the waste has many environmental and economical benefits especially now that pollution is a major...

From a Literature Review to an Alternative Treatment System for Landfill Gas and Leachate

Zhao, Rui; Huang, Tao; McGuire, Michael - In: Challenges 3 (2012) 2, pp. 278-289

This paper provides an alternative treatment system for landfill gas and leachate control in order to reduce the energy consumption and disposal cost, using the recycled landfill gas as the combustion promoter for incineration of the leachate. This study starts by providing a literature review...
