Waste for dehydration treatment is immersed in heated oil at a predetermined temperature under two-step depressurization conditions: mild depressurization at the beginning and strong decompression at the end, and dehydration and drying of the waste is performed. The waste for methane fermentation is used as feed, and the waste is subjected to methane fermentation treatment under anaerobic conditions, and the generated methane gas is used as an energy source for oil temperature dehydration treatment, etc., and the digested sludge is dehydrated and made into compost. The aim is to provide a method for recycling kitchen waste.

By applying oil-temperature dehydration treatment using heated oil as a heating medium under two-step depressurization conditions, high-quality feed that can be stored for a long time can be produced by drying the raw materials. By methane fermentation of waste and using the methane gas as an energy source for the above-mentioned oil-temperature dehydration treatment, there is no need to supply energy from other sources.Furthermore, the digested sludge from methane fermentation can be dehydrated and composted. By doing so, the above-mentioned kitchen waste can be fully utilized as a resource, and moreover, there is an effect that energy supply from other sources is not required.
