Examine the bottlenecks of waste home appliance recycling from a macro and comprehensive perspective
Based on previous research results and practical experience, Kowloon Machinery builds a recycling system framework for waste home appliances based on the theme of stimulating the recycling and processing of waste home appliances and on the premise of promoting the use of home appliance shredders. According to the different functions of the components involved in the waste home appliance recycling system, the system is divided into collection mechanism, processing mechanism and mechanism. The three major mechanisms are consumers, recycling and processing enterprises, and core centers. These core centers are respectively focused on finding promotion points. The breakthrough point of waste home appliance recycling attempts to examine the bottleneck of waste home appliance recycling from a more macro and comprehensive perspective.
Examine the bottlenecks of waste home appliance recycling from a macro and comprehensive perspective
To complete the incentives for recycling and processing of used household appliances, we need to have a comprehensive understanding of the recycling system of used household appliances as a whole. Viewed in isolation, recycling for the sake of recycling can only treat the symptoms but not the root cause. It can only temporarily improve the recycling efficiency of used household appliances, but cannot change the low recycling rate of used household appliances in the long term. Regard waste home appliances as a key component of the waste home appliance recycling department, find the reasons and problems of low recycling rates from all aspects of waste home appliance recycling, solve them one by one, and unblock the entire cycle chain, so that the increase in the recycling rate of old home appliances can be more sustainable. , reducing the pressure brought by electronic waste to the environment in the longer term, while also making the development of the entire home appliance industry more sustainable.
Recycling and thorough dismantling and recycling of used household appliance parts
Secondary recycling refers to the recovery and sale of old home appliance parts. Depending on the integrity of the parts and whether they can be used directly, the old home appliance parts flow to electronic and electrical manufacturers for reproduction and use, or to resource processing companies for resource processing. Basic methods for in-depth resource processing of waste household appliances include pyrometallurgy, wet leaching, processing with household appliance shredders and other recycling methods. The specific processing procedures include; manual disassembly; classification, roughly divided into chassis shells, circuit boards, mechanical transmissions, fixed mechanisms and glass; metal refining and recycling; leaded glass recycling, etc. The recycling and processing of discarded household appliances is a thorny issue, because waste plastics are difficult to recycle and need to be incinerated, which causes secondary harm to the environment. The cost of recycling leaded glass is too high and it is difficult to dispose of it harmlessly. At the same time, metal recycling The process causes serious pollution and the recycling rate of valuable metal materials is low. Therefore, complete crushing and dismantling requires high levels of recycling and processing enterprises and research and development.
Recycling and thorough dismantling and recycling of used household appliance parts
In response to the problem of high disposal costs, the Ministry of Environmental Protection issued the document “Notice on the Announced List of Subsidy Companies for Waste Electrical and Electronic Products Processing Funds”, which subsidizes home appliance recycling and processing companies based on the number of televisions, consoles, refrigerators, and air conditioners processed. A total of 43 waste electrical and electronic product processing companies in 15 provinces and cities including Beijing, Tianjin, Shanghai, Shanxi, Qianning, Heilongjiang, Fujian, Zhejiang and Jiangsu have received processing fund subsidies. In addition to companies receiving subsidies, there are also many small and medium-sized electronic waste recycling companies scattered throughout the country. Due to their limited scale, they only engage in recycling and dismantling of old electronic appliances, parts disassembly, deep processing of materials, metal refining and many other aspects. one or more of them. Small and medium-sized electronic waste processing companies purchase used electrical appliances or parts directly from recycling companies for processing. At the same time, processing companies have different business fields based on the professionalism of the links involved in their business fields. Each of them is responsible for the individual steps of clever dismantling, in-depth dismantling, and resource processing of waste household appliances.
