A New Method for Comprehensive Utilization of Kitchen Garbage

The paper discusses the disposal of kitchen garbage by means of comprehensive utilization. The method includes four steps: pretreatment of kitchen garbage; preparation of biodiesel from oil-phase by transesterification; Rhizopus oryzae TZY1 and Saccharomyces cerevisiae TZY0 were co-inoculated into water-phase for fuel ethanol production; preparation of protein feed from solid residue of fermentation. Advantage of the method is to make good use of the kitchen garbage, simplify the disposal process, with good prospects for industrial utilization.
