Abstract Nowadays, plastic products are closely related to human life. While it brings convenience to human beings, there are also great health and environmental threats. Most of the plastic products are polymer compounds obtained by addition polymerization or condensation polymerization. It will cause chronic poisoning to humans if long-term use plastic products are used. In addition, due to the relatively low production cost and short service life of plastic products, a large amount of waste plastics is discarded every year, which causes serious environmental problems. Traditional disposal technologies such as landfill and incineration not only waste a lot of resources but also accompany serious secondary pollution problems. In order to meet the needs of sustainable development and green environmental protection, various recycling methods have been explored for waste plastics, which have been used to develop economic and environmentally friendly value-added products. This paper reviews a range of management methods for the increasingly severe problem of discarded plastics and briefly summarizes the advantages and disadvantages of some methods, lists some examples of more valuable recycled products and materials, and finally puts forward the improvement direction and challenge to solve this problem. Keywords Waste plastics . Recycling . Management methods . Value added products . Challenges
1 Introduction As a member of three major synthetic materials, plastics have the characteristics of light weight, high strength, good insulation, and corrosion resistance and have brought a huge material civilization wealth to human beings. Plastic is called one of the greatest inventions in modern times [1–4]. With the continuous development of manufacturing technology, plastic products are gradually replacing traditional materials in various fields. Continuous updated data shows that global plastic

production has grown at an average rate of 2.7 times per year since 1950. As of 2018, global plastic production is about 359 million tons (MT) [5], as shown in Fig. 1. Among them, China’s total plastic product is about 60 MT, which has been the world’s largest producer and consumer of plastics. The development experience of countries around the world shows that the more developed the economy, the greater the consumption of plastic products. Acc
