A process includes calcining a high potassium carbonaceous waste product to form potassium oxide and carbon dioxide and reacting the potassium oxide and carbon dioxide to yield bio-based potassium carbonate. The process also includes catalyzing a reaction of a lignocellulosic biomass with abundant hydroxyl groups into a biopolyol using the bio-based potassium carbonate and brominating using a brominating agent a triglyceride to form a bio-isocyanate. In addition, the process includes reacting the biopolyol and the bio-isocyanate to form a polyurethane foam.

The present disclosure provides methods for generating sugars from a cellulosic biomass. The methods combine treatment of the biomass using a high-shear milling device and saccharification of the biomass to partially hydrolyze the biomass. The biomass can be saccharified either after or simultaneously with the high-shear milling treatement. The partially hydrolyzed biomass is then separated into a solids stream with saccharification enzymes, and a liquid stream with sugars. The solids stream and associated enzymes are further incubated under saccharification conditions to produce additional sugars, or are recycled and added to fresh biomass, which is saccharified under high-shear milling conditions. The methods result in improved conversion of cellulosic biomass to glucose.
