The benefits of recycling are the recycling industry of used goods and resources, which is called as the social vein industry in Japan, which contributes to the formation of a circular economic loop of "natural resource-product-renewable resource" within the scope of the whole society.The vein industry, namely the resource recycling industry, is based on the premise of ensuring environmental safety, for the purpose of saving resources and protecting the environment, and for the purpose of using advanced technology to convert the wastes generated in the production and consumption process into reusable resources and products, so as to realize the reuse and resource utilization of all kinds of wastes.It includes two processes: waste conversion to renewable resources and renewable resources processing into products.The rise of the vein industryTalking about the vein industry also has to start from the circular economy.The so-called circular economy, compared with the traditional linear economy, can be simply expressed as the circulation of the material elements that participate in economic activities has circular characteristics.Because of its recycling of national resources and energy, recycling industry has been on the rise.Waste recycling and environmental protection to deal with the bad situation in the field of waste recycling from the source, we should take environmental protection as the focus, from strengthening the environmental protection of many small recycling enterprises to start.First of all, the policy should strengthen the "small, scattered, chaotic" pattern of waste recycling enterprises.The problems caused by the large number of small enterprises are as follows: first, the recycling channel is occupied; second, the secondary pollution of the environment is serious.In this regard, some experts suggest that special development parks should be set up in each city, and enterprises engaged in waste recycling within the region should be unified under the management of the parks. Sewage treatment, garbage incineration and garbage landfill should be unified within the zones to prevent secondary pollution.Secondly, the recycling and processing enterprises should straighten out the cost allocation mechanism.Due to the lack of unified supervision in the industry, the cost burden is often all transferred to waste disposal enterprises, which will undoubtedly reduce the enthusiasm of processing enterprises.As Li Li, a researcher at the Solid Waste Pollution Control Institute of the Chinese Academy of Environmental Sciences, said, based on mature international experience, the disposal costs of goods should be equally shared by the seller, the treatment and the utilization enterprises.A more long-term step would be to build strong policy safeguards.Waste recycling involves a wide range, if only stay in the pure industry supervision level, can not achieve a very good effect, it is necessary to strengthen supervision from a higher level, to speed up the construction of waste commodity recycling laws and regulations, waste commodity recycling into the legal track.The experience of developing waste recycling in Japan is worth our reference.Japan's implementation of the "household appliances recycling law" provisions, consumers must waste air conditioners, refrigerators, television and washing machines and other household appliances, by the seller to return to the manufacturer for recycling.Sellers recycle the old home appliances returned by consumers and hand them over to the recycling factory, which is responsible for the preliminary disintegration of the home appliances and basically categorize them according to plastic and metal categories.Home appliance manufacturers then recycle it for further use.The cost of recycling is borne by the consumer.
