How to transform garbage into energy (BID) - Generation of electricity from biogas generated in final disposal sites of urban solid waste.

The present study aims to develop a methodology to evaluate the technical and economic feasibility for the generation of electricity from biogas recovered in urban solid waste (MSW) landfills. For this, a description of the technologies available for the generation of electricity from landfill biogas (GRS) is made, considering the advantages and disadvantages of each one.

The sources of greenhouse gas (GHG) reduction are also analyzed. These reductions are due, on the one hand, to the capture and combustion of the methane contained in the biogas, and on the other, to the replacement of fossil fuels that should be used to generate the same amount of electrical energy that was generated from the biogas.

Annex A shows as an example the technical feasibility of electricity production from the current generation of biogas in San Javier II, and of the projection from the MSW deposited in San Javier III and future modules in the City of Salta, Argentina.

The electricity production costs for the useful life of the project are analyzed, including the investment, operation and maintenance costs of the generation system, and the present value of the production cost per unit of energy generated is determined.

GHG reduction estimates are made for three scenarios considered. A description of the regulatory framework for the generation of electricity from biogas and the connection to the electricity grid is also included.
