Generally speaking, transfer stations only perform rough classification, because most of the current garbage is directly landfilled and does not need to be subdivided. In fact, a lot of garbage can be used for other purposes, such as composting to produce biogas, incineration to generate electricity, etc.
1. Almost half of the domestic waste is food waste. In addition, food processing plants, food supermarkets, slaughterhouses and other corporate institutions also produce a large amount of similar organic waste. These food wastes need to be shredded before further processing, and can be processed with biological methods for composting or biogas generation in the next step. Since food waste can be large or small in size, hard or soft, the processing effect of a general-purpose garbage crusher is not good enough. Based on the introduction of German technology, Thred has developed a low-speed, high-torque shearing crusher specially used for crushing food waste. The successful development of the food waste crusher has made my country's technology in the crushing of solid food waste The level has reached the world's advanced level. Currently, garbage production biogas projects are being implemented in Hainan and other places. But Baidu "China's first vehicle biogas project will be settled in Hainan this year to alleviate the gas shortage."
2. my country produces 150 million tons of garbage every year. The output of urban garbage increases at a rate of 8-10% every year. The cumulative amount of urban domestic waste is close to 8 billion tons. There are 80 million tons of accumulated garbage in the landfills around Beijing alone. It is not an exaggeration to say that the city is besieged by garbage. After years of accumulation, these wastes have very little moisture content and their calorific value is comparable to coal. This is a huge energy treasure house. It would be a waste not to use it. Like Japan, due to its advanced incineration technology, a lot of garbage is used for incineration and power generation.
Using these wastes can be used for power generation, steam production, cement manufacturing, etc. The problem now is that these garbage must be crushed to be evenly distributed in the furnace and fully burned. Since the garbage contains glass bottles, bones, fabrics, plastic films, bamboo and wood and other soft and hard materials, a professional garbage crusher is needed. There is SID abroad and Thred in China, both of which are doing well. Give me some points /
