How do Chinese garbage be disposed of in the end? Is there a need for classification?
If there is more understanding of the final disposal of the garbage, the answer to this question is self-evident.
Although environmental protection projects for waste gas and wastewater have become hot in recent years, in reality, the most difficult to deal with is solid waste. Whether it is technical threshold, policy support or capital cost, it is a problem. According to China's solid waste treatment ideas, it is reduced, resourced, and harmless. Reduction is to reduce the generation of garbage, skip it. Recycling and harmless, all need garbage classification, and the finer the classification, the more beneficial to reduce processing costs and improve recycling.
Professional waste disposal stations will have professional garbage sorting equipment, such as magnetic separation, semi-wet selective crushing and sorting, gravity sorting, etc., sorting metal, plastic, rubber, cloth, paper, etc. from garbage. Recycling is used; if the organic content is high, such as kitchen waste, it is used as a composting material; if it is not available, it is cured and harmlessly treated, and then landfilled.
So, this is the case. The process of garbage sorting, if it can't be done in the trash can, it has to add more sorting equipment at the waste disposal station. For users who generate garbage, garbage sorting does not cost anything. For waste disposal stations, it is a large amount of investment in technology, capital and manpower.
Of course, all of the above are ideal solid waste treatment methods. The reality of skinny is that it is a cloud of recycling. Waste incineration power generation is a loss of money. It directly builds a professional landfill in the suburbs. All landfills are directly landfilled. This is already worth the taxpayer's money. This is the practice in most cities, and this is the case in developed countries.
