An extruder-feeder biomass liquefaction process under DOE-sponsorship was developed at the Univ. of Arizona in the 1980s to produce liquid fuels as an alternative energy source. Since 1988, the work has been redirected toward organic solid wastes, particularly MSW, but with the production of by-products to enhance the economics. The technology is being transferred to the private sector, with emphasis on major reductions of wastes to landfills. Modular liquefaction plants can reduce wastes to landfills by 70 to 80 percent, compared to about 20 percent by recycling and some local composting alone. The process lends itself for small to medium-sized packaged plants that can be expanded from the basic 200 ton per day unit to 400 tons per day, and then later on to 800 tons per day. Some economic advantages can be achieved by (a) integration with a mini-MRF (materials recovery unit), and (b) modest amount of composting. Current research involves (a) the use of a light fraction of these oxygenated liquefaction products as a diesel fuel additive and (b) the formulation of a heavy fraction with recycled rubber and plastics for pavement asphalts. The overall economics appear attractive.
