Now that the process of urbanization is accelerating, people's living standards are also improving, and at the same time, more and more domestic waste is brought. According to statistics, the annual output of urban waste in my country is about 200 million tons. Faced with such a huge amount, if this urban waste cannot be effectively and harmlessly treated, it will cause serious pollution to the environment.
At present, municipal solid waste generally adopts three disposal methods: landfill, incineration, and composting. Metal substances are separated and reused, and the rest of the garbage can be made into RDF high-density particles for resource regeneration.
Kitchen waste can be turned into fertilizer after treatment. Kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce a bad smell. After proper treatment and processing, it can be transformed into new resources. The high organic matter content makes it possible to be used as fertilizer and feed after strict treatment, and can also produce biogas for fuel or power generation. The oil part can be used to prepare biofuels.
Kitchen waste refers to the waste generated in the daily life of residents and activities such as food processing, catering services, and unit meals, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea dregs, bones, etc. The main sources are home kitchens, restaurants, restaurants, canteens, markets, and other industries related to food processing.
