Waste glass recycling and disposal enterprises "can't eat enough"

according to the requirements of four-color garbage classification in residential areas, glass should be put into green garbage cans. This makes many citizens puzzled. How can the seemingly useless glass be put into the barrel that means environmental protection and green? "The disposal of waste glass in Shanghai can be completely digested. We especially hope that citizens can sort it at home." Lu Rongkang, the person in charge of Shanghai Shenhang Glass Co., Ltd., said that the factory's production capacity is 100000 tons, and now it is still in the state of "not enough to eat". It is expected that after the promotion of four-color classification, how can we choose the right manufacturer? Increase the recycling and disposal capacity, but the problem can be solved by expanding the production line. The key problem is that Shanghai citizens should cooperate with sorting

the utilization and recovery rate can reach 70%

yesterday morning, in Shanghai Shenhang Glass Co., Ltd., No. 51, Zhuhang Road, Minhang, the whole process of the modern cycle of waste glass was completely seen: the waste glass of several large ships was unloaded from the dock, sent to the conveyor belt and entered the plant, cleaned The rough milling experimental machine is installed in a clean, dry house with uniform temperature. At the same time, the possibility of making long beam zigzag experiments on the machine and the possibility of using a mirror extensometer for experiments should be considered, and it has entered the automatic sorting line; Under the surveillance of the camera, various colors of glass are automatically separated, and impurities such as plastic bottle caps and advertising stickers are picked out; The sorted transparent, brown and green glass are ground into fine particles, as if they were pure quartz sand, and put into the warehouse; Then it was loaded and transported to the downstream glass making company, put into the furnace, and turned into a beautiful new bottle, completing a real "rebirth"

"theoretically, glass can be completely recycled." Lu Rongkang, general manager of Shanghai Shenhang Glass Co., Ltd., said that the speed regulation range of glass varieties is narrow and diverse, including food glass, door and window glass, harmful glass, etc. now the main products are food glass, including ashtrays and other decorations, with a recycling rate of 60% to 70%. Even harmful glass such as lamp tubes and computer boards can be processed into artificial marble at a lower cost than natural marble, but the production line has not been put into operation due to the huge cost

the factory is in a state of insufficient food

"Shanghai's" 10msec "shows that 100 data measurements in one minute can completely digest waste glass disposal. We especially hope that citizens can sort it at home." Lu Rongkang said that the production capacity of the factory is 100000 tons, and now it is still in the state of "not enough to eat". Last year, we 'ate' 70000-80000 tons in total He said that it is expected that the promotion of four-color classification will increase the amount of recycling and disposal, but the problem can be solved by expanding the production line. The key problem is that Shanghai citizens should cooperate with sorting

according to Lu Rongkang, the glass that the company now recycles and disposes is still recycled from the society. There are many recycling points in the city, which are recycled from hawkers and then transported by water, with the characteristics of dispersion and spontaneity. According to statistics, 500 tons of waste glass are mixed into urban domestic waste in Shanghai every day, 90% of which are transported by water to the special wharf of the factory

however, a considerable part of waste glass has not entered the recycling system. "Due to the low cost of glass, many citizens do not sort it, but mix it with domestic waste, which affects the end treatment." The relevant person in charge of the municipal waste management office said that if waste glass is not sorted into the incineration plant, it will damage the boiler; If biochemical treatment and composting are carried out, the effect will also be affected. Now, all districts and counties have centralized recycling points, which are collected and transported by sanitation

since 2002, Shanghai has planned to build a number of waste recycling delivery stations, and determined the main business body of the sorting yard through public bidding, initially setting up a waste recycling network, and promoting the recycling of renewable resources such as waste metals, waste paper and waste plastics. Due to the special packaging requirements, high transportation costs, insufficient sorting sites and other factors, most of the waste glass from civil use is mixed with domestic waste for disposal, which has not been properly recycled, which not only increases the total amount of waste, but also fails to make effective use of resources
