Wow, the leftovers that were poured in turned into fertilizer in 24 hours!

"Wow, the leftovers that were poured in turned into fertilizer!" "This machine is really good, turning waste into treasure. The plants in the ecological farm will definitely grow better if they have fertilizer." In a school's garbage sorting practice class Above, facing a "big guy" with a square metal shell, the students' eyes were bright and full of curiosity.

This "big guy" is a kitchen waste disposal equipment introduced in Nanxun District. In the novel eyes of the students, the staff in the school cafeteria opened the lid of the machine and dumped the kitchen waste. I saw the "big guy" processing tank constantly "swallowing" vegetable stems and leftovers. Then, the staff showed the students the processed food waste, which has been transformed from messy kitchen waste into usable organic fertilizer.

The main principle that Suzhou Hongben Kitchen Waste Disposer can complete the conversion from garbage to fertilizer is to biodegrade the kitchen waste by adding aerobic bacteria and other bacteria in the mixing chamber. Compared with the past, this method is more environmentally friendly, efficient and convenient. "Take the school cafeteria as an example. About 300 to 400 kilograms of kitchen waste is generated every day. It was previously transported and processed by a third-party company. Now that this equipment is introduced, the waste can not only be treated on-site, but also twice. Utilize to realize the daily production and consumption of kitchen waste.

An efficient path explored from centralized processing to on-site processing. The staff of the waste sorting office in this district introduced that we attach great importance to and strive to promote the construction of a national demonstration city for domestic waste sorting. Focusing on the work requirements of relevant departments and the city's construction goals, the grassroots level promotes the implementation of waste classification, and optimizes all aspects of it. At present, this area has gradually realized the normalization of waste classification. Throughout the entire chain of garbage disposal, the classification of the "front-end" is complete, but the problem of disposal after garbage classification is still a major constraint.

Food waste is one of the "problems". Especially in areas with high population density, a large amount of food waste is generated every day. This kind of garbage has high humidity and easily pollutes the environment. In the past, this area has always used a centralized treatment method, but this method has a single terminal disposal method for garbage, and there are still problems such as large energy consumption, large area, storage and odor, and dripping during transportation.

In order to solve the above problems, a large number of investigations were carried out in the early stage, and the opinions of relevant departments and townships at the district level were solicited. Finally, the method of on-site disposal of kitchen waste was clarified and an implementation plan was issued. Then, the district screened out 63 units suitable for promoting on-site treatment of kitchen waste, including enterprises, institutions, large banks, hospitals and other canteens, farmer’s markets, etc. Starting from the key units, they began to gradually reduce the on-site treatment of garbage to Real place.

In the implementation process, in addition to selecting appropriate equipment and determining hardware installation matters, the area also focused on the specification of operating procedures, requiring each unit to identify at least one full-time person in charge and conduct operational training for relevant personnel. Nowadays, in the Nanxun town government canteen, there are dedicated staff responsible for putting daily food waste into the on-site treatment equipment of food waste for degradation, and the organic fertilizer produced is directly used as fertilizer for the trees in the town government, or Recycling by the equipment company staff for secondary composting.

Practice has proved that this method is an excellent way to deal with food waste. The use of on-site treatment equipment can carry out closed degradation of food waste, achieving a 90% weight reduction of food waste, with a daily processing capacity of 100 kg. The water and gas produced by the degradation can meet the standard discharge after equipment treatment, and the organic matter produced meets the national organic fertilizer standard and safety testing standard. It can be directly used for planting activities or unified secondary composting to increase fertilizer efficiency and sell it to the market.

In addition to environmental protection and resource-based disposal, this method also has the advantages of economical benefits.
