Abstract

Recent research into conversion of organic wastes at Murdoch University is reviewed to highlight interlinkages, insights gained and potential future research. Central to the research underpinning the success of the one vessel sequential aerobic (to bring temperature to thermopilic)-anaerobic (to extract methane)-aerobic (to produce compost) thermophilic process is utilising the concept of electron transfer, which links aerobic and anaerobic phases through electrons as a common currency. This concept is consistent with our ability to produce electricity from the process liquor using a microbial fuel cell. Management of the liquor has been found to be critical as it is a carrier of micro-organisms that perform all the biological processes in the reactor and assist with start up. Start up has also been facilitated by the presence of grass clippings in MSW. Linkages to nitrogen removal, unusual properties of liquor, grass clippings and possible pre-treatment of cellulose wastes using fungus are highlighted.
