The current food waste in Chongqing Liangjiang New District is collected and transported by the Heishizi Food Waste Treatment Plant in Jiangbei District, Chongqing. After inquiries, we found out that it was this processing company. It is understood that due to the rapid development of the economy, people's living standards are getting better and better, and the catering industry is developing rapidly. With the rapid development of the catering industry, the amount of waste oil generated in the use of kitchens has naturally increased. The amount of waste oil is huge. If it is not properly disposed of, it is a huge source of pollution. It should be recycled and reused. However, recycling and reusing kitchen waste oil is simple. , but now, it seems to be very troublesome to operate. The recycling of waste kitchen grease includes the recycling of hot pot oil. However, Chongqing is the capital of hot pot and has opened a special hot pot collection and transportation line. In addition to hot pot restaurants, other catering units that produce waste grease must also sign an "Agreement on the Recycling and Disposal of Waste Kitchen Grease" with Yuying Company, and can choose to install our company's patented product oil-water separator. Each catering unit shall pour the waste edible oil separated from the oil-water separator into our company's special kitchen waste oil recycling barrel. It is prohibited to consume it again and prevent it from flowing to the food industry, illegal units or individuals.
