Abstract:

Rising costs of nonhazardous solid waste SW disposal, along with strict environmental regulations, limited landfill capacity, and the difficulty in siting new incinerators and landfills make SW disposal a costly, complex problem for Army installations. Converting SW to alcohol is one proposed way to lessen the SW disposal burden. This study evaluated and compared two different proposed processes for converting municipal solid waste MSW and waste paper to fuel ethanol and other byproducts. To convert the cellulosic fraction of MSW to fermentable sugars, the first process uses a single stage of dilute acid hydrolysis, and the second process uses enzymatic hydrolysis. Both processes promise to minimize the amount of waste material that would otherwise be landfilled or discarded. Ethanol-a byproduct of these processes-will continue to increase in value and market share as a fuel, fuel extender, or octane enhancer that can help reduce U.S. dependence on imported oil. The study concluded neither process is presently ready for a single-step expansion to an economically viable, commercial-scale application. However, with continued development, both processes can serve as bases for detailed engineering and technology development studies leading to the design, construction, and operation of a commercial demonstration plant.
