Converting Nutritious Soil into Flower Fertilizer Piques Residents’ Interest in “Sorting”
Outside the northwest gate of Xiaonanzhuang community, Haidian Street, there is a soil nutrient conversion station that specializes in processing food waste, which can “eat” various perishable food waste such as leftovers and leaves. After “digesting”, you can “spit out” organic fertilizer, which can be used to grow flowers, plants and fruits. Kitchen waste is turned into nutritious soil on the spot, reducing further links in transportation and storage and realizing the resource utilization of the waste.
Recently, a reporter from the Beijing Youth Daily visited this working “artifact”. According to the site staff, a set of biochemical treatment equipment is installed in the soil nutrient conversion station, consisting of five main parts: a device for lifting a garbage can, a garbage sorting platform, a device for crushing and squeezing, a high temperature degradation device and a deodorization detection system. Next to the soil nutrient conversion station there is a smart waste sorting station. Residents put food waste here every day first. The smart system can record the weight of residents deposited in food waste and issue the corresponding points to residents’ accounts.
“Every morning and evening, we will help the staff to transfer the drained kitchen waste from the smart waste sorting station. After fixing the trash can to the machine, press the start button and the machine will automatically remove the waste from food in the trash can. Send it to your own mouth for digestion. ” Volunteer Mei Gang at the conversion station told the Beiqing Daily reporter that because the biochemical treatment equipment is installed in the conversion machine, the microorganisms in it will degrade kitchen waste and convert kitchen waste. in high efficiency granular organic fertilizers. The fertilizer has complete nutritive elements, which can not only improve the soil, but it is also non-toxic and harmless, and does not have unpleasant smell. It is a rare “flower food”.
Mei Gang said that the “journey” of kitchen waste did not end here. To encourage more community residents to actively participate in sorting garbage, they came up with a trick: exchanging points for “flower food”: residents can use the kitchen Points earned from waste are replaced with a corresponding amount of organic compost, which is used for planting flowers, plants, fruits and vegetables, in order to truly recycle and reuse kitchen waste in the community. At present, the processing station in Xiaonanzhuang community can process more than 500 kitchen waste cats every day and produce more than 100 nutritious soil cats.
Today this transformation station has become a “moving textbook.” According to Liu Chunying, secretary of the Xiaonanzhuang Community Neighborhood Committee, many community residents, especially children, have great interest in the working principle of the Soil Nutrient Processing Station. Volunteers We take the smart waste sorting station and the soil nutrient conversion station as teaching and advertising points on the site, and regularly conduct waste sorting advertising and educational activities, inviting residents to visit the site, learn on waste reduction and sorting knowledge, master waste sorting methods and demonstrate on site The garbage disposal process, understand the use of products after garbage disposal.
Liu Chunying said that since learning that the community uses biotechnology to treat kitchen waste, community residents have also been more motivated to sort the waste. They take the initiative to place sorted kitchen waste in smart waste sorting stations and pay particular attention to the biochemistry of kitchen waste. When dealing with progress, ask volunteers when organic fertilizer can be exchanged and there is often a situation where it is difficult to find “fertilizer”.
“This nutrient soil conversion station has also become a brilliant calling card for our street garbage sorting.” Li Xin, deputy section chief of the Haidian Subdistrict Urban Management Bureau, told the Beiqing Daily reporter that since the start of operations in May this year, the soil nutrient transformation station in Xiaonanzhuang community has also attracted staff and volunteers from other streets to visit and learn. In the future, Xiaonanzhuang community volunteers will continue to promote residents to do a good job of source sorting, raise awareness of environmental protection, increase the utilization rate of kitchen waste, and allow residents to community members are actively involved in sorting garbage.
