Approach for biogas generation

A process to make biogas, said process comprising the steps of:

• providing a digester adapted to receive a feed and capture a biogas composition resulting from biodigestion;
• adding to said digester at least one organic material and at least one inoculum capable of converting a portion of said at least one organic material into methane under anaerobic conditions;
• providing a biomass which is substantially free of lignin in an amount that ranges between 0.1 to 5% w/w of the total feed, comprising at least one other organic material;
• adding said biomass to said digester;
• allowing sufficient time for the digester to degrade at least a portion of said biomass and at least a portion of said organic material to yield a biogas composition comprising methane;
• optionally, continuously adding said biomass which is substantially free of lignin in an amount that ranges between 0.1 to 5% w/w of the total feed comprising at least one other organic material;
• capturing said biogas composition;
• optionally, storing said biogas;
• and
• wherein the biogas is methane that is produced by using a substantially lignin-free and unbleached cellulose as an additive and further wherein the substantially lignin-free and unbleached cellulose is obtained by a delignification process.

A process to increase the amount of methane produced from a bio-digester, said method comprising the steps of:

• providing a digester adapted to receive a feed and capture a biogas composition resulting from biodigestion;
• adding to said digester at least one organic material and at least one inoculum capable of converting a portion of said at least one organic material into methane under anaerobic conditions;
• providing a biomass which is substantially free of lignin in an amount that ranges between 0.1 to 5% w/w of the total feed, comprising at least one other organic material;
• adding said biomass to said digester;
• allowing sufficient time for the digester to degrade at least a portion of said biomass and at least a portion of said organic material to yield a biogas composition comprising methane;
• continuously adding said biomass which is substantially free of lignin in an amount that ranges between 0.1 to 5% w/w of the total feed comprising at least one other organic material wherein the biomass includes unbleached cellulose as an additive and further wherein the substantially lignin-free and unbleached cellulose is obtained by a delignification process;
• capturing said biogas composition;
• and
• optionally, storing said biogas.
