WSU Scientists Crack the Code to Low-Cost Biofuel Production
2025-05-06

Scientists at Washington State University (WSU) have developed a novel method for producing low-cost sugar from corn stalks and other crop waste, paving the way for sustainable biofuel production. Their process utilizes ammonium sulfite-based alkali salts to pretreat corn stover at mild temperatures, enabling enzymes to break down cellulose into fermentable sugar without chemical recovery. By offsetting production costs through byproduct sales (including fertilizer), the resulting sugar could cost as little as 28 cents per pound, competing with imported sugar. This breakthrough promises to significantly improve the economic viability of biofuels and advance sustainable energy solutions.
