Landfill biogas energy production

With a plant of this type, the biogas produced in landfills is conveyed by appropriate wells, with one or more collectors that serve food to groups of internal combustion Otto cycle to produce electricity.

Normally, landfills are not exploiting the heat produced by engines as not necessary for the process. You still have energy that is typically injected into the entire network. Plants of this kind are now in decline as a function of the fact that the waste is typically used to feed plants or biomass energy plant.
