Abstract: In one example, a process to make biogas includes providing a digester which comprises at least one organic material rich in nitrogen 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 depleted of lignin; 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; capturing said biogas composition; and storing said biogas. Also disclosed, are methods and uses associated with the use of a cellulosic component processed to be depleted of lignin which comprises approximately between 10% to 50% of the amount of lignin present in a biomass component prior to a delignification treatment, as additive to organic waste in a bio-digester.

Abstract: In one example, a method includes providing a recalcitrant biomass; exposing said highly recalcitrant biomass to a delignification reaction wherein said delignification reaction comprising the exposure of said highly recalcitrant biomass to an acidic composition comprising a modified Caro's acid for a period of time sufficient to yield a treated cellulose which has a final lignin content of up to 100% less than the initial lignin content of the biomass; providing a digester whose contents comprises at least one inoculum comprising a microbial community capable of converting organic material into methane under anaerobic conditions; adding said treated cellulose to said digester; allowing sufficient time for the digester to degrade at least a portion of said treated cellulose and optionally, at least a portion of said organic material to yield a biogas composition comprising methane; capturing said biogas composition; and storing said biogas.
