where is the kitchen waste from the restaurant

and

located on the second floor of the basement? How to avoid gutter oil flowing back to the dining table? How to reduce the pollution caused by kitchen waste? In the

and

shopping malls, kitchen waste treatment is a “test”. In addition to advocating “small bowl dishes” and “half dishes” and other saving methods, Chengdu is also experimenting with the on-site disposal of kitchen waste to reduce kitchen waste from the source.

and

are the first distributed kitchen waste disposal demonstration project in Wuhou District of Chengdu. Yesterday, a reporter from Chengdu Business Daily Red Star visited the kitchen waste treatment station at Jinnan Tianjie commercial complex in Longhu. He found that the project covers a small area and “sewage” can be reused. It will be promoted in other areas of Chengdu, especially in commercial complexes and school canteens.

are small and big appetites.

and

wastewater can be treated and reused. If there is no sign at the door, it is difficult to pay attention to this kitchen waste treatment station in the corner of the parking lot. The reporter saw at the scene that there was no sewage on the ground of the treatment station, and there was no peculiar smell around. It was difficult to connect the appearance with “garbage treatment”.

“the whole processing station is only 43 square meters, and the floor area of the machine is smaller.” Wang Yanjun, the project leader and deputy general manager of Sichuan Tianfu Oasis Environmental Protection Technology Co., Ltd., told reporters, “the daily processing capacity of this machine is 3 tons. In fact, at present, the daily garbage generated by catering businesses in Jinnan Tianjie commercial complex in Longhu is about 1.5 tons. This machine can fully meet the kitchen waste treatment needs of the whole commercial complex.” Where does

and

come from? Where are we going after we’re done? The reporter learned at the scene that the catering businesses in the shopping mall will send kitchen waste to the treatment station twice a day. After 10-24 hours of transformation, the kitchen waste will be converted into oil substances and water meeting the class III discharge standards. Among them, oil can be used to produce biodiesel, incineration power generation, water can be directly into municipal sewage pipes or used to irrigate green space. How does the process of

transform from kitchen waste to up to standard discharge water? It mainly depends on “microbial enzymolysis technology of food waste”. “After entering the machine, kitchen waste is separated from oil and water, and then digested by biological enzymes in the machine. This process is normal temperature, no odor, no noise, because this process does not need to be heated alone, greatly reducing energy consumption. ” Wang Yanjun said, “the direct recycling of kitchen waste, easy to run in the transport process, causing secondary pollution. Kitchen waste contains salt and oil, so it is not suitable for direct landfill treatment or incineration power generation. At present, the best treatment scheme is to adopt distributed treatment, that is to build treatment stations in the places where kitchen waste is generated, so as to reduce waste and pollution from the source

and

kitchen waste treatment efficiency improvement

and

will gradually promote the source treatment of kitchen waste

reporter learned from the comprehensive law enforcement bureau of Wuhou District that in 2019, the comprehensive law enforcement bureau of Wuhou District, in accordance with the “Chengdu kitchen waste distributed treatment work plan”, coordinated the cooperation between the third-party kitchen waste disposal service enterprises and the property management Party of shopping malls, and adopted the commercial mode to build this distributed kitchen waste on-site disposal project. The relevant person in charge of the comprehensive law enforcement bureau of

and

told reporters that this mode is led by the government to coordinate, organize and provide policy support. The third-party service enterprises invest funds and equipment and are responsible for construction and operation. The property management party is responsible for providing venues and organizing catering businesses to carry out classified collection and centralized disposal. Catering businesses pay the disposal fees to the third-party service enterprises.

Wuhou District Comprehensive Law Enforcement Bureau, said that from October 1, 2019 to now, Longhu Jinnan Tianjie commercial complex has reduced the garbage by 90%. After biological enzyme treatment, the main products are carbon dioxide and sewage, and the remaining 10% inorganic substances (such as plastic bags, disposable tableware, etc.) are put into other garbage and transported to Nanqiao domestic waste compression station for harmless treatment.

and

reporters learned from the commercial complex of Jinnan Tianjie in Longhu that more than 80% of catering businesses in the commercial complex choose to treat kitchen waste innocuously on site. Take Haoke restaurant as an example. The restaurant produces about 50-100kg of kitchen waste every day. The kitchen waste treatment station comes to the door to collect it every day, and the restaurant pays the garbage treatment fee to the treatment station. In this way, the cost of self-treatment of kitchen waste is reduced, and the treatment efficiency of kitchen waste is improved.

Wang Yanjun also told reporters that at present, there are different types of kitchen waste treatment equipment, with processing capacity from 100 kg to 10 tons or even more, which can be flexibly arranged according to actual needs. It is expected that the cost will be recovered in two to three years through the mode of collecting garbage treatment fee from cooperative merchants, and a virtuous circle of benefits can be realized at present. “In the future, we plan to promote such kitchen waste treatment stations in the city, especially commercial complexes, school canteens and other units, so as to realize the on-site treatment of kitchen waste as far as possible, and reduce the pollution of kitchen waste from the source.”

and

at the same time, we also advocate to save food, put an end to waste, and reduce the production of kitchen waste from ordering dishes.
