Abstract

Treatment of municipal solid wastes (MSW) yielding high value products, in this case ethanol, energy and enriched plant growth media, are the objectives of this R&D program. The process includes combined treatment and resource recovery of MSW based on dilute acid hydrolysis and alcohol fermentation. It was found that the optimal conditions for the acid hydrolysis are: temperature of 230-235°, pressure of about 30 atm., pH value of about 0.5 and reaction time of 8 to 15 seconds. Under these conditions glucose yield of about 60% can be achieved. Methods to overcome toxicity problems while achieving high ethanol yields (>85%) in high substrate concentrations (TS=25%) were developed, as well as techniques for by products utilization.
