New Ideas on Environmental Protection of Plastic Packaging

First, corn starch resin is promising for replacing plastic packaging materials. Green Environment At present, many countries in the world are conducting research on replacing bio-degradable resins with existing plastic packaging. The corn starch resins that have been successfully researched in Japan and Taiwan in the near future have broad prospects for development. This resin is made from corn and plasticized. The packaging material made from it can be disposed of by burning, biochemical decomposition, insect feeding, etc., thus eliminating the "white pollution" hazard.
According to recent information from Taiwan, the number of plastic bags produced per ton of corn resin at the present level is almost the same as that produced by plastic pellets.
According to statistics from the plastics industry in Taiwan, the world produces approximately 100 million tons of plastic products each year, including 30 million tons of disposable packaging materials. Addressing the pollution caused by these materials requires a large social cost. If corn resin can successfully replace some of the packaging plastics, it is estimated that there will be a market worth US$10 billion annually.
Second, the commodity "over-packaging" is not desirable. The elimination of excessive packaging not only significantly reduces the source of plastic packaging waste, but also greatly saves the earth's resources. For example, under the conditions of reasonable choice of sports packaging, it is entirely possible to reduce the multilevel of sales packaging. The reuse of plastic packaging is also a way to reduce the source of packaging waste.
Third, adhere to the reuse of plastic packaging. In fact, the reuse of packaging is already an effective method for transport packaging. There is also a possibility of implementation in sales packaging, especially in the case of consumer goods that have a large sales volume and are widely available, and are likely to be packaged for reuse or refilled. For example, the foreign detergent industry is rapidly turning to concentrated products and related heavy-filling forms. Fabric softeners have been supplied in Europe and North America in the form of heavy-filled, concentrated products for many years, gaining widespread consumer acceptance.
Fourth, recycling of plastic packaging waste must take a comprehensive approach. Because not all plastic packaging wastes have the value of material recycling, especially large quantities of mixed plastic packaging wastes and packaging materials that contain toxic substances (such as medicine bottles, pesticide bags, and medical plastic waste), they are not suitable for use. Material recycling methods to deal with, but rely on chemical recycling or energy recycling law.
Fifth, the potential for biodegradable plastic packaging is unlimited. At present, the country has included degradable plastic packaging as a priority area for development. Degradable plastic packaging has a large market potential in fields such as agriculture, daily chemicals, medicine, and food. It is estimated that in 2000, the output of plastic packaging in China was more than 3 million tons, of which disposable plastic packaging, which was difficult to recycle, accounted for about 30%. The amount of plastic garbage generated was more than 1 million tons, and the plastic film production was over 400,000 tons. With only about 400,000 tons of authentic products and nearly 2 million tons of plastic waste generated, the prospects for degrading plastic materials are far-reaching. However, it should be pointed out that degradable plastics cannot be regarded as a panacea for solving plastic packaging wastes, and there are limitations in the application performance of the packaging, especially whether it can adapt to a variety of food packaging, and efforts must be made.
