    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: Method for controlled delignification of lignocellulosic feedstock and conversion of lignin depolymerization products into at least one ester compound, said method comprising the steps of: providing an acidic composition having a pH of less than 1, said acidic composition comprising: an acid selected from the group consisting of: sulfuric acid; an alkylsulfonic acid; and an arylsulfonic acid; a source of peroxide; an alcohol selected from the group consisting of C1-C6 linear alcohol and C3-C6 branched alcohol and mixtures thereof; exposing said lignocellulosic feedstock to said acidic composition for a period of time sufficient for the acidic composition to react with the lignocellulosic feedstock to obtain a liquid phase containing lignin depolymerization products and diester compounds and a solid phase comprising cellulose fibers; optionally, separating the liquid phase from the solid phase recovering a mixture of diesters, lignin monomers and cellulose fibers; and optionally, separating said lignin depolymerization products from said diester compounds.

    Abstract: A one-pot process to separate lignin from a lignocellulosic feedstock, where the process involves the steps of: providing a vessel; providing the lignocellulosic feedstock; providing a composition that includes: an acid; a modifying agent including a compound containing an amine group; and a peroxide; exposing the lignocellulosic feedstock to the composition in the vessel for a period of time sufficient to remove at least 80% of the lignin present in the lignocellulosic feedstock; and, optionally, separating and removing a liquid phase that includes dissolved lignin fragments from a solid phase containing cellulose fibres.

    Abstract: A process to separate lignin from a lignocellulosic feedstock, said process comprising the steps of: providing said lignocellulosic feedstock; providing a composition comprising; an acid; a modifying agent selected from the group consisting of: sulfamic acid; imidazole; imidazole derivatives; taurine; a taurine derivative; a taurine-related compound; alkylsulfonic acid; arylsulfonic acid; triethanolamine; and combinations thereof; a peroxide salt; and a peroxide; exposing said lignocellulosic feedstock to said composition for a period of time sufficient to depolymerize substantially all of the lignin present in said lignocellulosic feedstock into lignin oligomers and lignin monomers; wherein said process is carried out at atmospheric pressure.

    Abstract: Method for controlled delignification of lignocellulosic feedstock, said method comprising the steps of: providing a reactive phase of pH less than 1, said reactive phase comprising: water; sulfuric acid; a source of peroxide; a modifying agent, said modifying agent adapted to control the reactivity of the sulfuric acid; providing a holding phase, said holding phase comprising an organic solvent which does not react with the aqueous acidic composition; combining said reactive phase and holding phase to form a reaction mixture; exposing a lignocellulosic material to said reaction mixture for a period of time sufficient to allow delignification of the lignocellulosic material.
