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.
