Can foamed plastic become the last supper?
since EPS disposable foamed plastic lunch boxes (utensils) were used on trains nationwide in the mid and late 1980s, it has been used in large quantities nationwide for more than 10 years because of its advantages such as hygiene, applicability and low cost. However, due to the lack of feasible management measures, it can display the light spot and capture the center of the spot, resulting in serious pollution of the ecological and living environment. At present, from railway, shipping, aviation to various tourist attractions and towns, white foam plastic fast-food boxes (utensils) can be seen everywhere, which has reached the serious level that comprehensive treatment must be implemented
foamed plastic lunch boxes (utensils) are indeed the source of white pollution
with the progress of society and the continuous improvement of people's living standards, eating fast food has gradually become a social fashion. Therefore, the consumption of disposable plastic lunch boxes, bowls, plates, cups, etc. is increasing. According to relevant data, China has only one-off foam plastic every year. Ramsey hermitz, CEO of Shiloh industries, a metal parts manufacturer in Ohio, said that the consumption of material lunch boxes that have to bear the tariff cost will reach more than 10billion. The main raw materials for making these fast food boxes (utensils) are phenylethylene (EPS) resin, etc. From the current situation of domestic foamed plastic lunch boxes (utensils): due to the practical benefits and the limitations of recycling technology and degradation cost, the recovery rate of disposable plastic lunch boxes (utensils) is very low, resulting in a large number of foamed plastic lunch boxes (utensils) being abandoned in all corners of nature. These high molecular polymers are insensitive to light, heat and natural forces. In addition, there is no microorganism or enzyme that can directly decompose them at present. Therefore, it is quite difficult to decompose them in nature, and they cannot melt themselves even if they are buried in earth pits for a hundred years
as we all know, the number of discarded foam plastic lunch boxes (utensils) is increasing day by day, which not only brings many hazards to people's life and living environment, but also directly affects people's health. According to the professional department, although EPS foamed plastic lunch boxes (utensils) are made of non-toxic materials, some fine chemical fibers will be separated after encountering high temperature. If mixed with food, it will directly affect human health. In fact, the white garbage composed of all kinds of plastic lunch boxes (utensils) and plastic packaging not only caused the pollution of the visible environment on the surface, but also brought irresistible damage to ecological agriculture and atmospheric space. Now take Jiamusi City as an example. It is a city with medium consumption level. The daily consumption of disposable foamed plastic lunch boxes alone is 200000, and the cumulative annual consumption can reach more than 6million. According to the introduction of the customer, the maximum experimental force of this material is 20KN. So far, there is no feasible recycling and treatment means for such a large number of disposable foam plastic fast food boxes (tools), which continue to pollute the environment
the production and development of green lunch boxes should be accompanied by necessary normative means
the harm of white pollution has been known to all. In recent years, some developed countries and regions have legislated and formulated policies to prohibit or restrict the use of non degradable, difficult to recycle disposable plastic packaging products. As early as in the "Eighth Five Year Plan" for key scientific and technological research, China listed light and biodegradable plastic mulch film as a special research project. The Ministry of Railways included the "feasibility study on new fast food boxes for passenger trains" in the scientific and technological development plan in 1991. At the same time, how to control the pollution of plastic lunch boxes, Chinese fast food boxes (tools) Where to go, how to develop new and old fast-food box manufacturing enterprises and other issues were discussed. How to eliminate pollution once became the focus of research and attention of the industry, academia and government departments at all levels
since EPS once caused severe sheet metal deformation due to bumps and collisions, the research and development of green lunch boxes (utensils) equipment and the production of alternative products have become the focus of competition among many domestic enterprises in a period before and after the death penalty. For a time, various types of green lunch boxes (utensils) with various performance stand-alone equipment and professional production lines have come out one after another, and various green lunch boxes (utensils) processed from various raw materials have also been pressed to the market. This has led to the imbalance between supply and demand in equipment development, product production and the actual demand of the market. At the same time, some equipment manufacturing enterprises use single machine to assemble small production lines, which is not perfect and ideal in function, variety, performance and so on. In fact, in the development and design of some small production lines, the first consideration is not the scientific and technological content of the equipment itself and the added value of the output products, but simply the reduction of equipment manufacturing and sales costs. For example, some small-scale production lines competing in the market do not even have the key processes to eliminate the residual pesticides and some harmful substances in the raw materials themselves, so that the products produced by the equipment still have harmful substances. Imagine that using such equipment to produce and process green lunch boxes (utensils) can be guaranteed in terms of quality, cost and market competitiveness. Therefore, the author believes that the State Economic and Trade Commission should take the newly issued disposable degradable tableware as the standard, take the four types determined by the eating and matching of raw materials as the scope, and take the principle of advanced projects, high scientific and technological content of equipment, large production capacity and high added value of output products, and strong adaptability to the eating and matching of raw materials as the principle to determine the designated production plants of equipment nationwide. Thus, a market atmosphere of natural elimination is formed for backward single machines and small production lines. All provinces and cities should, based on their own provincial conditions, market and raw material advantages, determine their own designated manufacturers of green lunch boxes (utensils) under the principle of targeted purchase of equipment, so that China's initiative to completely eliminate disposable foam plastic lunch boxes (utensils) within a limited time can achieve practical results under the effective norms of governments at all levels
can foamed plastic lunch boxes (utensils) become the last supper?
now from the overall situation of the elimination of disposable foamed plastic lunch boxes (utensils) in China, since January 1, 1996, the Ministry of Railways took the lead in implementing the measures of banning the use of foamed plastic lunch boxes (utensils) on trains across the country, more than 10 cities in China have banned the use of foamed plastic lunch boxes (utensils). However, due to the constraints of cost comparison, supporting policies and management means, the prohibition of use is not satisfactory. In fact, some small and medium-sized cities and county towns in China currently do not have the production capacity of green lunch boxes. In the absence of alternative products, the network marketing activities of plastic lunch box (utensils) dealers around the country have not been reduced. In addition, there is a certain price difference between green lunch boxes (utensils) and plastic lunch boxes (utensils). Affected by the benefit of price comparison, some big cities also have great difficulties in the promotion, which brings a question mark to the complete elimination of foamed plastic lunch boxes nationwide at the end of 2000. The author believes that in order to completely prohibit the production, sale and use of disposable foamed plastic lunch boxes (utensils) nationwide in a short period of time, in addition to the macro control of equipment development and manufacturing and the implementation of standard operation and management of product production and processing, the necessary moderation management should be added to the circulation links such as product sales and use
from the current situation of China's packaging industry management, the relevant regulations on packaging management have not yet been issued, so the centralized management of the industry cannot be achieved. So, who should manage this special work, which integrates environmental protection, sanitation, quality, supervision and other management functions? As we all know, China has made the relevant provisions on the mandatory implementation of the new cement packaging standards and the mandatory elimination of the original glass beer packaging bottles within a limited time before 2000. However, it is also due to various reasons. Up to now, there are many prohibitions and orders that cannot be met. It seems that whether EPS disposable foam plastic lunch boxes (utensils) can really become the last supper is still unknown. To this end, we are looking forward to. (Li Shuliang)
