In 2004, the apparent consumption of plastic raw materials nationwide was 38.133 million tons, and the total output of plastic products of enterprises above designated size nationwide reached 18.846 million tons, an increase of 12% over the same period of the previous year; of which the main products in plastic packaging products (including films, sheet bars, The output of plastic wire and woven products, plastic containers and containers, daily use, and other products is over 6 million tons. Foam (excluding polystyrene disposable lunch boxes, which was 50,000 tons before being banned in 1999) was 859,500 tons, an increase of -0.22% year-on-year, accounting for 4.7% of the total.
Plastic packaging is the largest proportion of the plastics industry. The average annual growth rate is higher than the average growth rate of other plastic products, reaching over 15%, which is nearly twice the annual average growth rate of China's GDP, highlighting its strong social demand and economy. The objective needs of development. Various foam plastics have excellent properties such as thermal insulation, heat insulation, shock absorption, corrosion resistance, etc., and can be adjusted according to the need to adjust the foaming ratio to effectively reduce the cost characteristics. They are widely used in construction, packaging, heating, transportation, furniture, etc. industry.
1 The Cause of "White Pollution"
Discarding plastic bags, mulches, and disposable lunch boxes is the main cause of “white pollution†rather than the responsibility of the plastic material itself. After the plastic film was used, it was difficult to recover and the plastic film pieces were abandoned in the fields, resulting in so-called “white pollution.†Afterwards, the disposable lunch boxes were discarded on both sides of the railway to form people’s visual pollution. Since then, they have joined this rank, followed by ultrathin plastics. bag. In Japan, after use, the mulch film has to rely on manpower to clean up the abandoned film in the field. The main body of this work is women. Nowadays, Japan has successfully developed a biodegradable plastic film. Although the price is high, it has saved the labor costs of manually picking up the mulching film and is being applied in large areas.
It is undeniable that the use of plastic mulch film has made great contributions to farmers' increase in production and income, known as the "White Revolution," and it is still in use. It is an important production material for agricultural production and an effective means to solve the problems of agriculture, rural areas and farmers. In 2004, the output of agricultural film reached 728,700 tons, an increase of -3.28% over the previous year. Polystyrene-foamed disposable lunch boxes have made outstanding contributions to the convenience of people and the saving of meal time due to their high quality, low cost, and hygienic characteristics and their extremely competitive characteristics in the industry. Polystyrene disposable lunch boxes are still used around the world. The use of these materials has shown great vitality from the very beginning and is an environmentally friendly material.
As an important part of the national economy, China's plastic products industry has been developing in a sustained, rapid, healthy, and stable manner in recent years, making great contributions to the rapid development of the national economy. Any evaluation of plastics should respect science and follow the principle of seeking truth from facts. Regarding the statement that "plastic bags are poisonous", all plastics were considered non-toxic at the EC Basel conference. The reference to "refusing to use plastic bags" is unrealistic and does not meet the national conditions. Refusal to use or disable plastic bags is not in line with economic development and people's lives.
2 Recycling waste plastics is the main way to solve plastic environmental problems
The widespread use of plastic inevitably brings about environmental burdens. It is estimated that China will produce at least 5 million tons of waste plastics each year. Most plastics are recycled as much as possible after they have lost their use value due to its high recycling value and the highest calorific value of waste. In China, most plastics are recycled after use, and the outlook for the recycling of waste plastics is very attractive. Disposable plastic products, though account for a small proportion of the total amount of plastics, can also be recycled and reused. However, they are easily discarded because of their low recovery value after use. Due to their excellent corrosion resistance characteristics, plastics are not easily rot and lighter in weight. If it is not dealt with in a reasonable and timely manner, it will be easily discarded and unfavorable to the environment.
The current high oil prices, plastic raw materials significantly increased prices, plastic processing companies difficult to follow, if you take reasonable measures to make disposable plastic lunch boxes are recycled, not only to protect the environment, but also to achieve renewable resources, waste plastic recycling Can be. Furthermore, environmental protection and resource regeneration are also the goals of China's 21st century vision. For example, the selling price of calcium carbonate-filled polypropylene lunch boxes in September 2004 was as high as 4,500 to 5,300 yuan/ton.
3 To deal with waste plastics environmental issues and "white pollution" to take a comprehensive approach to governance
What kind of disposable tableware made of materials can be accepted by the society without polluting the environment is actually a problem that we should seriously explore. The material used first should be non-toxic or non-polluting. Dishware made of any kind of material must be properly disposed of in the environment if it cannot be completely absorbed by the environment within a certain period of time.
At present, fast food boxes used in the market include pulp molded, calcium carbonate-filled polypropylene, and other materials. According to relevant media reports, the hygienic and quality qualification rate of snack boxes currently used in Beijing is only 60%. The condition is not present before the polystyrene snack box is forbidden. In other words, the fast food boxes using the above-mentioned materials not only cannot solve the problem of environmental pollution, but also have new problems such as poor quality and unsatisfactory hygiene. At this stage, the fast-food box used by our country has a very poor market and will directly affect the image of Beijing during the 2008 Olympic Games. How to solve the fast food box problem, the country's eyes are looking at Beijing.
It is not difficult to solve this problem. Biodegradable plastics are now widely used in many fields. If you use this material as a fast food box, you can solve the above issues of hygiene, quality, and environmental pollution. However, the material is expensive and it is difficult to accept the market.
Another solution is to learn the practice of Shanghai and re-use polystyrene materials. Establish fast food boxes to recover effective operating mechanisms and systems, strengthen legislation, encourage recycling, strengthen publicity and education, and engage the entire community to develop good habits.
