Plastic packaging recycling approach

Plastic packaging has been rapidly developed and widely used in the field of packaging materials since the 1970s because of its excellent characteristics such as light weight, high strength, convenience and low price, which greatly facilitates people's life. However, because most plastic packaging materials are difficult to degrade naturally, their packaging waste will form permanent waste and cause pollution to the environment. Therefore, when using and designing plastic packaging materials, we should fully consider the degradability, recycling possibility and recycling ways of plastic packaging materials. The government should also take measures to promote the research and development of degradable plastics to promote the development of circular economy

according to the latest statistics provided by the National Bureau of statistics and the Light Industry Federation, the main economic indicators of China's plastic products industry achieved overall growth in 2005, with an increase of more than 25%, and the total industrial output value reached 501.1 billion yuan. According to the analysis of people in the industry who are about to pay the "packaging tax", although the price of plastic raw materials remained high in 2005, the strong market demand, the increase in exports, the development of new application fields and the growth in the output of high value-added products still promoted the use of trowels to flatten the surface, and the overall growth of the economic indicators of the industry. At present, packaging has become the largest user of plastics, with an annual consumption of more than 6 million tons

however, exquisite plastic packaging often turns into waste in an instant. With the rapid growth of plastic packaging, the environmental problems are also becoming increasingly serious. In particular, the waste of disposable plastic packaging materials is large, scattered and messy, which is difficult to collect

some of these wastes are discarded and scattered on the ground at will, polluting the city appearance and environmental landscape, and bringing adverse effects on economic development and ecological environment

in order to solve this problem, the government, enterprises and the majority of scientific and technological workers have done a lot of work. There are some who advocate using less, restricting and banning; It is necessary to advocate and formulate local regulations to enforce the implementation of degradable plastics; It is also proposed to use economic means (taxes and charges) to guide consumption. Unfortunately, many measures have had little effect. People feel inconvenient to use 13365312612 mobile phones for 24 hours and disable them, while charging increases the burden on people

facts have proved that modern society is inseparable from plastics. It is better to dredge than to cut off blockage. We should use materials with better performance and price ratio, develop degradable plastics with technologies and methods that are more in line with the characteristics of the times, and increase the research on plastics. The key point is the recycling and reuse of graphene supercapacitor waste, which is the way to solve "white pollution". The author believes that at present, the recycling and treatment of plastic packaging material wastes should adopt a multi-channel and multi-channel method, and rank them according to the meaning beneficial to the sustainable development of the ecological environment. The first is recycling, the second is recycling or incineration to obtain energy, the third is landfill, and the fourth is to replace them with biodegradable materials

recycling is mainly applicable to pallets, turnover boxes, large packaging boxes, plastic barrels and other containers used for transportation and packaging. For plastic packaging that is easy to recycle, physical and chemical modification can be used for regeneration, so that limited materials can be recycled. For those disposable plastic packaging containers that are difficult to recycle, incineration, landfill or replacement with biodegradable materials will be a good choice. Although it is difficult to point out which method is the best, we should emphasize which method is more suitable. According to the actual situation in various regions and fields, choosing the right one is the best
