<p>The present invention relates to the refining of municipal solid waste (MSW) to produce methane using an anaerobic digestion process for the treatment of the biodegradable fraction of MSW. The method according to the invention comprises steps, wherein a) municipal solid waste (MSW) is fed to a pretreatment wherein a biodegradable fraction is separated therefrom and recovered; b) the biodegradable fraction from step a) is fed to an anaerobic digestion process, wherein biogas and a liquid reject is produced, and the biogas containing methane is recovered; and c) at least a fraction of the remaining part of the waste from step a) wherefrom a biodegradable fraction has been separated is pyrolyzed in a pyrolysis unit.</p> |
