Status of Global Waste Sorting

Waste sorting has been carried out in developed countries around the world for a long time, such as Japan, Germany, and Sweden, and is currently in a relatively mature stage. Reviewing foreign experience in waste classification, we can summarize several aspects of experience: First, resource utilization is an important trend. From the development experience of countries with successful waste classification, we can see that these countries have largely turned waste into treasure by means of incineration to generate electricity or heat, compost, and recycling. Resource recovery utilization. Second, a good incentive and constraint mechanism. Economic incentives and legal constraints have an important impact on promoting residents' waste sorting. Third, a clear and clear garbage classification system. The classification is clear and operable, which helps residents to effectively classify domestic waste and reduce the cost of terminal treatment.
