NOVELTY - A lytic enzyme recovery sorbent suitable for use in production of renewable materials, comprises a substrate; and an enzyme binding material dispersed with respect to the substrate.    USE - As lytic enzyme recovery sorbent suitable for use in production of renewable materials; in lytic enzyme recovery unit; in lignocellulosic biorefinery; for recycling lytic enzymes suitable for production of renewable materials (claimed); and in the production of biofuels and/or chemicals. The renewable material includes substance or item that has been at least partially derived from a source or process capable of being replaced by natural ecological cycles or resources, such as chemicals, chemical intermediates, solvents, monomers, oligomers, polymers, biofuels, biofuel intermediates, biogasoline, biogasoline blendstocks, biodiesel, green diesel, renewable diesel, biodiesel blend stocks, and/or biodistillates. The renewable materials are derived from a living organism, such as plants, algae, bacteria and/or fungi.    ADVANTAGE - The enzyme sorbent has a reversible binding efficiency of at least about 60% on a molar basis. The sorbent reduces usage enzyme costs and produces renewable materials in most cost effective manner. The hydrolytic enzymes act as catalyst and are not consumed in reactions to depolymerize lignocellulosic material thereby reducing operating costs and production costs of the renewable material. The recovery and recycle of cellulase enzyme improves the economic viability of lignocellulosic conversion to renewable material. The recycling of lytic enzymes reduces the total amount of lytic enzymes needed for lignocellulose hydrolysis and conversion to renewable materials such as fuels and/or chemicals.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a renewable material made using the sorbent;    (2) a lytic enzyme recovery unit suitable for use in production of renewable materials, comprising: a feed line for receiving a feed stream containing lytic enzymes; at least one enzyme recovery device containing an enzyme sorbent for sorbing the lytic enzymes, where the at least one enzyme recovery device is in fluid communication with the feed line; a regeneration line for supplying a release material to the at least one enzyme recovery device, where the regeneration line is in fluid communication with the at least one enzyme recovery device; and a recycle line for removing the lytic enzymes from the at least one enzyme recovery device, where the recycle line is in fluid communication with the enzyme recovery device;    (3) a renewable material made in the unit;    (4) a lignocellulosic biorefinery suitable for production of renewable materials comprising: a hydrolysis unit for depolymerization of cellulose and hemicellulose to a renewable-based feedstock by use of lytic enzymes; a conversion unit for receiving at least a portion of the renewable-based feedstock and converting into a renewable material; a separation unit for receiving a conversion unit effluent and forming a renewable material containing stream and a byproduct stream; at least one enzyme recovery unit for receiving the conversion unit effluent, where the renewable contains stream, or the byproduct stream, where the at least one enzyme recovery unit sorbs lytic enzymes for recycle; a regeneration line to supply release material for release of the lytic enzymes from the at least one enzyme recovery unit; a recycle line from the at least one enzyme recovery unit to the hydrolysis unit for recycling the lytic enzymes; a product line from the at least one enzyme recovery unit or the conversion unit for the discharge of the renewable material; and a byproduct line from the at least one enzyme recovery unit or the separation unit for the discharge of the byproduct;    (5) a renewable material made in the biorefinery;    (6) a process of recycling lytic enzymes suitable for production of renewable materials, involving sorbing lytic enzymes on an enzyme sorbent to separate the lytic enzymes from a remainder of an input stream; and releasing the lytic enzymes from the enzyme sorbent; and    (7) a renewable material made by the process.
