Full Scale Experiments in the Desiccation of Biosolids and Food Waste for Biofuel Production

Abstract

Full-scale operating trials were conducted utilizing an in-vessel composting tunnel to determine if a biofuel could be produced from feedstocks of food waste and dewatered biosolids. The process utilized the heated, escaping air from the composting step via an air-to-air heat exchanger to desiccate the material to a targeted moisture content of 20% or less. The end product quality was thoroughly tested and compared to conventional compost product quality, as well as suitability as a biofuel.
