A method of depolymerizing a biopolymer in a biomass is presented, the method comprising the step of contacting the biopolymer with a reaction system comprising at least one catalyst, at least one electron source, and at least one solvent. A second method of depolymerizing a biopolymer in a biomass is presented, the method comprising the step of contacting the biopolymer with an electrochemical cell comprising at least one catalyst, at least one solvent, at least one electrolyte, an anode, and a cathode. A third method of depolymerizing a biopolymer is presented, the method comprising the steps of providing a biopolymer; adding a photoredox-active functional group to the biopolymer to form a modified biopolymer; and irradiating the modified biopolymer with light in the presence of a reaction mixture; said mixture comprising a photoredox catalyst.
