Development of bio-based and biodegradable plastics in China

Because plastic products consumers and consumption links are relatively scattered, it is difficult to supervise consumers, the focus of supervision is the source management, increase the supervision of production links; The second is to increase the supervision of merchants and increase the cost of violating the law; The third is to make merchants willing to use plastic alternatives through taxation, subsidies and other means.

First of all, the use of biological products should be promoted from large and medium-sized cities with strong government governance ability, good economic foundation, high level of public awareness, sound plastic waste recycling measures and perfect regulatory system. Secondly, these cities are also concentrated areas of consumption of non-degradable plastic shopping bags, disposable plastic knives and forks and other products, and the implementation of solid plastic reduction policies in these places is conducive to rapid achievement of results. At the same time, the consumption power of consumers in these regions is strong, which is also conducive to the government and enterprises to promote plastic substitutes, and it is also conducive to the regulatory authorities to sum up the experience and model of the ban on plastic, and promote it on a larger scale in the country.

Strengthen positive publicity and guidance

Personal consumption is the main force of the use of biodegradable and biodegradable plastics, and the change of everyone's consumption behavior can eventually make the industry change, and individuals' cognition of biodegradable and biodegradable plastic resources, as well as the awareness of plastic's environmental harm and management are lack of professionalism, and more industry professionals need to organize exchanges and activities with non-governmental organizations and educational institutions. First, strengthen positive guidance, so that the general public become a new trend and new fashion to actively use green products; The second is to strengthen the publicity of the harm of plastic waste to the environment, the ocean, animals and humans themselves, and form the feelings of reducing the use of plastic products, which is to love society and love themselves; Third, community governments can increase the use of plastic substitutes for typical events, enterprises and individuals to dig, promote the use of plastic products to reduce the method, set a typical and example, to guide consumers to consume correctly.

Strengthen the research of sorting technology and equipment and the construction of composting sites

Waste biobased and degradable plastics need to be treated in the right way or place in order to achieve the characteristics of biobased and degradable plastics, and biobased and degradable plastics need to be properly sorted to avoid flowing into the recycling system of conventional plastics. First, it is necessary to increase the research of sorting technology and equipment. The degree of automation and success rate of sorting equipment of domestic equipment manufacturers are also increasing year by year, and the most commonly used sorting means is to use the difference of plastics for classification and sorting, using vibration, air flow and liquid flow sorting. Optical sorting technology is based on the radio and television sensor to analyze the visible light, infrared, ultraviolet and other spectrum of the material, identify the material for sorting. Second, it is necessary to increase the construction of composting and other places. It is necessary to use green credit, green manufacturing and other means to increase policy support, innovation to support the research of sorting technology and equipment, and the construction of enterprises in composting and other places to reduce fees and taxes, loan discount interest, listed green channels and other policy support, and give tilt to land, electricity, water and other aspects, and increase financial subsidies.
