Abstract: Embodiments of the present disclosure pertain to methods of removing lignin from a material by associating the material with a deep eutectic solvent (DES) that includes at least one hydrogen bond acceptor (HBA) and at least one hydrogen bond donor (HBD). The methods of the present disclosure may also include one or more steps of heating the solvent-associated material, separating the material from the solvent, drying the material, washing the material, and/or processing the material. Additional embodiments of the present disclosure pertain to delignified materials that are formed in accordance with the methods of the present disclosure.

Abstract: The present invention includes a bioplastic and a method of making a bioplastic comprising the steps of: dissolving a low quality cellulose biomass in a solvent, wherein low quality is defined as having little to no textile value; regenerating cellulose fibers by removing the solvent; plasticizing the cellulose fibers in the presence of a polyol into a plasticized film; and hot pressing the plasticized film into the bioplastic.
