At a regional level, Amini and Reinhart [18] evaluated the recovery of landfill gas in Florida (USA) by applying selected modification to the LandGEM model. The modified assessment considered the generation of electricity via direct combustion and an equivalent gaseous fuel, although an economic evaluation of the end-product cost was not incorporated. An alternative approach was discussed by Schneider et al. [19], who proposed an evaluation of the use of landfill gas for electricity production (LGTE), MSW use for refuse-derived fuel (RDF) in the cement industry, landfill gas flaring, waste-to-energy (WTE) (also known as incineration and thermal treatment) and mechanical–biological treatment (MBT). The assessment was conducted by comparing the specific reduction cost for the above-mentioned alternatives. Each conversion route was evaluated for a typical plant size.
