FIELD: process engineering.
SUBSTANCE: invention relates to ecology and environmental protection. It describes the underground decontamination of wastes with production of biogas. In compliance with proposed method, wastes in the form of suspension pH=6…8 consisting of solid domestic wastes, drilling wastes, industrial and domestic sewages, and initiating additive are periodically forced in at least one existing injection well of gas, gas condensate or oil wells with final reservoir fluid extraction fluid factor. Note also that feed pressure does not exceed the bed fracture pressure. Thereafter, biogas formed is extracted via operation wells.
EFFECT: simple and cheap extraction of biogas formed in biodegradation of wastes.
