[Explanation] Recently, at Wuhan Institute of Business and Technology, a "black technology" that specializes in dealing with kitchen waste can be used to convert useless waste into regenerated fertilizer, which can "eat" 5 tons of kitchen waste every day and "spit it out" "The cost of 500 kilograms of fertilizer and 1 ton of garbage is only 70 yuan.
[Explanation] On September 10, the reporter saw at the garbage disposal site of Wuhan Institute of Business and Technology that after the operator pressed the button of the "Integrated Organic Waste and Biochemical Treatment" equipment, the special bucket filled with kitchen garbage slowly rose to the conveyor belt to remove the garbage. Pouring out.
The pretreatment system first screens all the garbage, and the solid materials enter the "aerobic fermentation system", and then undergo aerobic fermentation and compost to produce organic fertilizer.

Our current organic waste disposer has a design scale of 5 tons. This part of the organic waste in this school can be transformed into high-quality organic fertilizer through a high-temperature and aerobic fermentation process, which will then serve the school’s landscaping. And the high-quality organic fertilizers that can be used on the market, supporting fruit (planting).
[Explanation] Dong Jun, the person in charge of equipment research and development, introduced that through biological means, we can convert solids in organic waste into organic fertilizers and liquids into biofuels to realize the recycling of organic waste.
The whole system realizes automatic control, automatic data transmission and storage and remote monitoring through the'electric control system', and reduces the kitchen waste by more than 90% within 24 hours. Through the comprehensive treatment of water, gas and slag, the kitchen is truly realized. Reuse, harmless, and reduce garbage.

What we produce in our lives is that it has a high moisture content and is easy to rot, and its characteristic is that it is rich in organic matter.
For example, we eat leftovers from the kitchen and cut the unwanted rotten leaves from the kitchen, as well as the leaves and branches of our tree, and the aquatic plants in our lake. These are rich in organic matter and can be used. To turn it into organic fertilizer.
[Explanation] It is understood that this "integrated organic waste biochemical treatment" technology was jointly developed by the teachers and students of the School of Environmental Sciences of Wuhan Business School and the technical staff of the partner company Hubei Junji Water Treatment Co., Ltd., and was the first to be applied in Wuhan Business School. It has played a good exemplary role in promoting the effective treatment of organic waste and building a green campus circular economy.

Previously, there was no recycling of food waste, and the main purpose was to do a simple recycling before, mainly for a simple treatment of recyclable waste.
Then most of the other garbage is transported to the landfill or incineration plant designated by the government along with ordinary garbage for processing.
So we used to spend about 300,000 yuan every year on garbage removal.
After the food waste is treated, it becomes organic fertilizer, which can then be used for the greening of the school and the fertilization of flowers, plants and trees.
[Explanation] According to the introduction, the equipment can also accurately process different types of organic waste. Food, kitchen waste, urban manure, garden waste, straw, livestock manure, sludge, etc. can all be used for aerobic fermentation and production Into organic fertilizer.
