The invention relates to a method for reclaiming biogenic mass, in particular sludge, wherein the product to be reclaimed is first dried and then thermally decomposed in a pyrolysis reactor for the purpose of creating pyrolysis gas. The method according to the invention is characterized in that the product is thermally dried in at least two drier stages arranged after one another, wherein the waste heat of the drier stage downstream of the product in the transport direction is used as process heat for the respectively upstream drier stages. The invention further relates to a system for reclaiming biogenic mass, in particular sludge.
