Potential and Cost Estimation of Biomethane and Electricity from Residential Solid Waste in Chile

C. Bidart, A. Gordon, A. Moraga, C. Pincheira & R. González
The potential energy concentrated in municipal solid waste (MSW) is estimated in Chile by following a proposed methodological approach for potential analysis. Alternatives to the utilization of landfill biomethane via direct burning (LBE), MSW incineration to generate electricity (IC), and collecting and upgrading to feed into the grid (LBI) were carried out. These alternatives are evaluated and compared using criteria such as cost of generation, environmental implications, legal conditions and short­term challenges for the country....
