Exploring the Idea of ​​Circular Economy in Polystyrene Foam Tableware (8)

4 Points of View and Suggestions

4.1 PSP cutlery is the preferred product of current disposable fast food tableware

In summary, PSP tableware is not the culprit of “white pollution”; it is non-toxic and harmless, and it is safe and safe; it can be recycled and recycled. From the comprehensive analysis and evaluation of resources, energy, application performance, hygienic performance, recycling and degradation performance and price (see Table 2), except that the raw materials are not from renewable resources, they are more difficult to recycle and degrade after use. Items are better than all kinds of one-time fast-food tableware, that is, the sex / lattice ratio is the best variety of disposable tableware. Therefore, under the current situation that the substitute technology and economic issues have not yet been completely resolved, there are still many problems in the application and sanitary performance, and there is a large demand in the market, PSP tableware is undoubtedly the preferred product of the current one-time fast-food tableware. The prospect of returning to the market is good.

4.2 PSP fast food tableware should belong to the green packaging category

At present, in the minds of many people in the society, there is a vague and narrow concept of green packaging, which mistakenly defines only packaging materials made of degradable materials as green packaging instead of the entire life cycle (LCA) of the product. From the cradle to the grave to evaluate its impact on the environment. According to the commonly used 3RID principles abroad (Reduce reduction, Reuse recycling, Recycle recycling, Degradable degradable) and LCA evaluation as a guideline, the definition of green packaging: raw materials and product production process materials, waste, waste Small quantity, energy saving, and no pollution; the use of the product does not cause any harm to human health; after the product is used, its waste can be recycled, recycled, recycled, or easily degraded, and it will not cause pollution or damage to the ecological environment. According to the definition and concept, PSP tableware should belong to the category of green packaging.

4.3 The recycling of PSP discarded tableware is a social system project. It must speed up the establishment and increase of science and technology investment.

According to foreign data reports, PSP cutlery has been recycled in foreign markets and is still a popular fast food tableware on the market. Many examples from home and abroad show that PSP tableware can be recycled. However, it must be fully realized that its recycling and recycling are quite difficult, mainly due to its decentralized application, light weight, large volume, and difficulty in collection. In particular, the characteristics of Chinese food in China are different from those of western foods. , Oil and water pollution is serious, cleaning water consumption is large, and often due to cleaning is not clean to bring great pollution to the secondary processing environment, its renewable materials can only make some middle and low products. Therefore, as soon as possible to set up PSP tableware recycling network, unobstructed recycling channels, the establishment of recycling system engineering and industrial chain, increase investment in science and technology, efficient recovery, cleaning technology, advanced recycling technology and equipment for in-depth research and development, in particular, how to effectively clean, Water conservation, recycling of wastewater, development of compatible compatibilizers, processing aids, modifiers, etc., to improve the quality of recycled materials, and the development of high value-added products, this will help enhance the market competitiveness and vitality of PSP tableware.

4.4 The combination of recycling and degradation is the development trend of the governance of disposable fast food tableware polluting the environment.

Drawing on foreign experience and strengthening the recycling of plastic packaging waste, it can not only effectively manage “white pollution”, but also achieve the purpose of resource reuse. It fully meets the concepts of resource conservation, environmental harmony, and circular economy, and is the development of packaging industry in countries all over the world. The main trend. However, in real life, not all packaging wastes are easy to collect and use effectively, and PS's main raw materials come from the shortage of limited petroleum resources, so raw materials from renewable resources are used as a supplement for recycling, namely foreign 3RID The pattern is worth paying attention to.

In recent years, China has invested a large amount of manpower and financial resources in research and development of alternative products in the PSP tableware market. Although it has made some progress, it has so far been technical, practical, hygienic, economical, and environmentally friendly. There are still varying degrees of problems that need further study to improve and improve, especially the cost needs to be greatly reduced, which is also the main reason for the prohibition of PSP tableware. However, with the advancement of science and technology and the application of practical tests, the production technology of alternative products will continue to improve, mature and costs will continue to decline. In particular, biomass plastics such as starch-based plastics, polylactide PLA, and carbon dioxide copolymers have been developed in recent years. Their raw materials are all derived from the renewable agricultural product resources or the comprehensive utilization of carbon dioxide waste gas. Their application performance and hygienic properties are close to ordinary plastics. After use can be fully biodegradable, return to natural circulation, but also easy to recycle recycling. Although the current cost is high and the market is difficult to accept, as the scale increases, the cost will become more and more reasonable, which is a development direction worthy of attention. Therefore, in the disposable fast food tableware market, recycling and degradation will complement each other, promote each other, and become a development trend of effective use of resources, protection of the environment, and prevention and control.

4.5 Starting from the actual situation, amending the decree will help promote the healthy and orderly development of the disposable tableware market.

The formulation and promulgation of laws and ordinances and decrees should proceed from reality, help to regulate the market, and promote the healthy and smooth development of the market. However, from the implementation of the 6th order over the past 6 years, since the decree has not proceeded from the national conditions, it has been unable to fully consider the current civilized and fast lifestyle without the disposable tableware, and the market has not developed the performance and price close to that already widely available. Consumers love the reality of PSP cutlery. After PSP cutlery is completely banned, how to ensure market demand has become a serious problem. Therefore, the decree does not and cannot fully play its due role. Coupled with the difficulty of law enforcement management and poor supervision, the quality and price of the fast food tableware market over the years has been confusing and the problem has become increasingly serious. In view of this, we recommend that relevant departments of the State make necessary amendments to this decree based on the principle of seeking truth from facts and the principle of the scientific development concept. The preliminary practice of recycling and recycling in Beijing in previous years, and the “source control, mandatory recovery, The gradual prohibition and encouragement of alternatives to the "16-character principle of comprehensive governance" and the "3-point project" have accumulated a lot of useful experience and have achieved remarkable results, which can be used as a reference. This will not only help ensure the effective supply of the market and improve the quality of people's lives, but also help improve the ecological environment, the effective use of resources and promote the development of circular economy.
