Leveraging the advantages of kitchen waste resources of central enterprises, rich experience in grease trade, a professional trade service team, and a strict risk control system, a resource utilization plan for the entire "collection-production-sales" industrial chain of kitchen waste grease has been constructed. This has realized the transformation of kitchen waste grease from "harmless treatment" to "resource utilization" and "productization", producing renewable green energy products such as industrial-grade mixed oil (Used Cooking Oil) and biodiesel, which are exported to large petroleum companies and biodiesel plants in many countries and regions such as Europe, the United States, and Southeast Asia, with an annual export volume of 150,000 tons.
