Description
Íthalo de Abreu and a team of co-authors test food waste as a biofuel source in Brazil in a study from two thousand twenty-four. Food waste pollutes soil and water and releases greenhouse gases, but it also holds sugars that can ferment into bioethanol. The team compared acid and enzyme routes to free those sugars.
Waste was pretreated by removing fats, then hydrolyzed with enzymes or with sulfuric acid under varied heat, time, and load. The best sugar yield came from strong acid at high load and temperature for one hour. Acid treatment was slightly more efficient than the enzyme route. Fermentation with yeast gave the best ethanol yield from the acid-treated raw waste. Fat removal did not change the breakdown steps.
