The project was funded by the United Association of Solid Waste Management for Crete (ESDAK) and its goal is the estimation of the produced biogas at the Pera Galinoi landfill, using computer models. The landfill located in the Prefecture of Heraklion, Crete. The study also includes data on the amount of incoming solid waste and existing facilities, such as biogas collection network, waste disposal sites, sealing and drainage of landfills, sludge disposal site of the Heraklion’s WWT facility, drainage collection network, drainage collection network, etc.
The present study examined the current situation at the Pera Galinoi landfill and assessed the possibility of generating electricity from the produced biogas. The study examines a number of factors that may be responsible for the reduction of biogas production, such as the quality characteristics of the leachate (salinity, high concentrations of heavy metals and ammonia) and the deposition of baled and bio-dried MSW in the cells, with a greater degree of compression, compared with the compression subjected to the raw MSW entering the landfill. Finally, the report presents a comparison of the various available electricity generation technologies, both technically and economically, and proposes the most appropriate one.
