The invention discloses a disposal method for kitchen waste. By adding agriculture and forestry materials and kitchen slurry which are mixed to prepare a fermenting bed body in a conventional disposalprocess of resource utilization of the kitchen waste, materials become thoroughly decomposed favorably, and the recovery utilization ratio of agriculture and forestry garbage is improved. By adding cultures which degrade grease efficiently and are high in salt resistance in a fermenting process, processes of oil-water separation and water desalination are not needed in the whole flow, so that thedisposal process of resource utilization of the kitchen waste can be optimized, the steps are reduced, and use of energy sources and equipment is saved.
