Method for enhanced biogas generation

A process to make biogas, said process comprising:

• providing a digester adapted to receive a feed and capture a biogas composition resulting from anaerobic digestion;
• providing said feed comprising:
• a first component comprising at least one inoculum comprising a microbial community;
• a feedstock component comprising:
• a second component comprising at least one organic material preferably rich in nitrogen;
• and
• a third component comprising a treated biomass component whose initial lignin content has been depleted by an amount ranging from 50% up to 90% by a prior treatment step, wherein said treated biomass component is present in an amount that range between 0.1 to 5% w/w of the weight of said feedstock,
• wherein said at least one inoculum is capable of converting a portion of said at least one organic material into methane under anaerobic conditions;
• adding said feed to said digester;
• allowing sufficient time for the feedstock to be degraded wherein at least a portion of said third component and at least a portion of said second component is converted to a biogas composition comprising methane;
• optionally, continuously adding said feed comprising said biomass which is depleted of lignin in an amount that ranges between 0.1 to 5% w/w of the total feedstock comprising at least one other organic material;
• capturing said biogas composition;
• and
• optionally, storing at least a portion of said biogas.
