Treatment of Municipal Solid Wastes (MSW) yielding high-value products, in our case ethanol, energy and enriched plant growth media, are the objectives of this R & D program. The process includes resource recovery and combined treatment of MWS based on dilute acid hydrolysis and alcohol fermentation. The hydrolysis experiments were carried out at the Technion in a batch reactor and at the New York University in an extruder type reactor. It was found that the optimal conditions for the acid hydrolysis are: temperature of 230-235°C; pressure of 30-32 atm., pH value of about 0·50 and reaction time of 8-15 s. Under these conditions glucose yields of about 60% can be achieved. Methods to overcome toxicity problems while achieving high ethanol yields (better than 85%) in high substrate concentrations (TS = 25%) were developed, as well as techniques for byproducts utilization.
