PROCESS AND DEVICE FOR GARBAGE RECYCLING AND RECYCLED PRODUCT FROM GARBAGE

摘要

PROBLEM TO BE SOLVED: To shorten the time required for piling fermentation (composing) of garbage, thereby to reduce the amount of ammonia generated in the fermentation, to enable sanitary treatment of a waste liquid discharged from the fermentation state and to produce good quality compost as a fertilizer, in a garbage recycling process using a garbage recycling device. SOLUTION: This garbage recycling process using the garbage recycling device involves performing lactic acid fermentation so as to shorten the time required for the fermentation to about two weeks and separating a liquid vessel 8 from a fermenter 3 so as to sanitarily treat waste liquid discharged from the fermentation stage, wherein further, a combination of this lactic acid fermentation and aerobic fermentation is performed so as to smoothly composting the garbage in about 30 days, raw sugar, rice bran and oil cake are added to garbage to be treated and the resulting mixture is subjected to lactic acid fermentation, to smoothly perform the fermentation, garbage containing various cells of bacteria/fungi is mixed into the garbage to be treated so as to promote the growth of yeast, and also, scale-up of this garbage recycling device to a plant scale is performed so as to treat a large amount of garbage everyday.
