Biotransformation is an effective way to realize the deep resource utilization of food waste. How can Chengdu, which produces over 2000 tons of kitchen waste every day, efficiently "turn waste into treasure"?
On May 19th, the Chengdu Kitchen Waste and Waste Oil Resource Utilization Association issued an initiative to implement a parallel collection of "oil and residue" separation lines, improve resource utilization, and create a "Chengdu model of oil residue separation".
As the City of Gastronomy, Chengdu is also one of the first national pilot cities for recycling and harmless treatment of food waste. Wang Jinhua, secretary-general of Chengdu Food Waste and Waste Oil Recycling Association, said that at present, Chengdu has established the technical route of 3L biotransformation of food waste. "3L refers to fuel, feed and fertilizer. The cooking waste is separated from oil and water at the front end, and the waste oil is processed into biodiesel; the meal residue at the middle end after oil and water separation is used for biotechnology transformation, and becomes Hermetia illucens fly larva, which is the protein raw material in the feed; and the end residue is digested by Hermetia illucens, and produces insect dung, which becomes high-quality bio organic fertilizer, allowing resources to flow back to the field."
On May 19th, the third council of the association was elected and established. We will focus on promoting advanced technologies and establishing a 'Chengdu model' for separating oil and water from kitchen waste, "said He Zhongming, the president of the association. We will serve as a bridge and link between the government and enterprises, improve the intelligent collection and transportation system, implement grid based management of" production collection and transportation ", implement" four fixed "management (fixed point, person, vehicle, and route), clarify relationships, implement responsibilities, establish accounts and trace sources, and ensure the reduction of kitchen waste and waste oil The harmless and resourceful disposal work proceeded smoothly.
On the same day, the association also issued an initiative to promote the benchmarking of Shanghai's advanced model, implement parallel collection of "oil and residue" separation lines, promote the implementation of an integrated business model for the collection, transportation, and disposal of kitchen waste oil, and create the "Chengdu model of oil residue separation".
