A few days ago, she met a friend who said that the current media has been advocating the concept of recycled paper. She is very concerned about this matter and has consciously kept the used waste paper, but until she resigned, no one came to recycle these papers. I believe many people have encountered this situation. My friend's words have led to a heavy topic in the paper industry. On the one hand, we are vigorously promoting the concept of regeneration, on the other hand, no one has effectively implemented it. What is the problem? What are the bottlenecks in the promotion of recycled paper

the paper industry calls for "recycling"

waste paper refers to the waste of paper products that are more popular than people after consumption (including a small amount of printed publications). This kind of waste has a characteristic, that is, after people consume, the essence of the main fiber has not changed, and it can still be used for papermaking. Therefore, recycling waste paper is recycling fiber. The paper industry calls this recycled fiber "secondary fiber"

according to statistics, every ton of waste paper used in the paper industry is equivalent to saving 3 cubic meters of wood, 1.2 tons of coal, 600 kilowatt hours of electricity and 100 cubic meters of water. Faced with such amazing figures, the United States virtue "The development of PU materials is to create a wide range of properties. Countries such as China have legally enforced that paper enterprises must use a certain amount of waste paper raw materials. Germany recycles 4million tons of waste paper every year, accounting for 83% of the total waste paper volume; Japan and Switzerland have the highest forest coverage in the world, but more than half of the waste paper in the country can be recycled; the annual waste paper recycling in the United States is as high as 42million tons, which has been used since 1992 for the upgrading of the industrial structure Recycled office paper. According to Ms. liyuhua, Deputy Secretary General of the China papermaking association, the consumption of secondary fiber in China's paper industry currently accounts for about 50% of the raw materials of the paper industry, which is far behind that of developed countries

the pollution of the paper industry is mainly caused by the structure of papermaking raw materials. The problems are mainly concentrated in small and medium-sized enterprises, especially those with wheat straw pulp as raw materials, which is a major obstacle to the development of the paper industry. Due to the lack of rich forest resources, non wood fibers account for 48% of China's papermaking raw materials, most of which are wheat straw pulp. If waste paper is used, the pollution problem can be greatly alleviated

China's paper industry imports millions of tons of waste paper from abroad every year, and it is growing every year. In 2000, the import of waste paper reached 3.71 million tons, an increase of 47.6% over the previous year, with a total cost of 245 million US dollars. While importing waste paper at such a large cost every year, a large number of waste paper to be recycled in China has not been used. Taking paper as an example, Beijing now has hundreds of newspapers distributed, with at least dozens of tons distributed every day, of which 70% - 80% of the waste paper can be recycled, but the actual amount of recycling is far from reaching this standard, and a large amount of waste paper is wasted

who hindered the promotion of recycled paper

paper mills are in urgent need of investment: due to serious pollution, the state has recently closed a number of small paper mills, and the huge cost of pollution control has also forced some paper mills to close themselves. If the recycled waste paper is used as the raw material of papermaking, the degree of pollution can be greatly reduced, and the material cost can be greatly reduced. Ms. Li Yuhua believes that if conditions permit, these small factories can avoid the fate of closure and alleviate the current situation that China's paper production cannot meet the demand and imports a large number of foreign paper products. However, the problem is highlighted: after the waste paper is recycled, a series of process operations such as pulping, screening, purification... Deinking, bleaching, etc. need special equipment and liquid medicine, especially for the reuse of some high-grade paper, more advanced equipment and liquid medicine are also needed, and what problems should be paid attention to in the maintenance of an imported deinking system electro-hydraulic servo universal testing machine will cost millions of dollars, which for some small factories, It is undoubtedly a heavy burden

there is no unified classification standard: Waste brings confidence to extruder enterprises. After paper recycling, there should be a classification problem, and then the paper mill will deal with it in different ways according to the length of paper fiber. At present, the way of waste paper classification in China is relatively vague, which is only divided into simple categories, and there is no specific classification standard in the industry. This limits the reuse of waste paper to a great extent. Foreign waste paper classification standards have been quite perfect. According to Ms. Li Yuhua, now the printing standards committee is preparing the classification standards of waste paper and the formulation of relevant standards, including the classification standards of waste paper recycling, the determination standards of the content of stickies in waste paper and the determination standards of ink residues in waste pulp. The implementation of this work will be of great significance to the classification of waste paper recycling and imported waste paper in China

lack of effective recycling channels: at present, China's waste paper recycling channels also rely on waste recycling stations to a large extent. Due to the inability to take the initiative to facilitate the masses, even with the advantage of price, these traditional recycling points are also shrinking. Another group of people, outsiders of ring carts, is gradually becoming the main body, and the stability of this group is relatively poor, so waste paper recycling is in an unstable situation. The channel of waste paper recycling has not been fully opened, especially the channel of large industrial institutions that produce professional waste paper has not been fully opened

in the transportation sector, the waste paper recycling industry is also facing another embarrassment. The consumption of paper products in big cities is relatively large. These cities have made various restrictions on the models and weights of transportation vehicles on the main roads, and the paper mills are mainly located outside the city or in relatively remote areas, so the recycled paper faces the problem of being unable to be transported out, which fundamentally limits the amount of waste paper recycling. According to reports, many units or individuals put forward the primary condition for recycling manufacturers is that "the manufacturer is responsible for door-to-door transportation". However, Beijing's large trucks are restricted in the city. At present, the seventh paper mill can only rely on five minivans to rush around day and night, and many government agencies and organizations have to queue up for waste paper transportation

it will take time for the concept to change: the woman mentioned at the beginning of this article is actually only a few. Although the media has hyped the concept of recycling, the application of recycled paper is far from reaching its due level. Beijing No.7 paper mill is the only paper mill in Beijing that specializes in the production of recycled paper. Its daily output of recycled paper can reach more than ten tons, but now the daily sales volume of the mill is only dozens of tons. There is still a lot of work to be done to promote recycled paper. A key problem is that people's ideas have not changed. At present, the application field of recycled paper in China is relatively narrow. In addition to postcards and business cards, recycled paper for office use is even less. In foreign countries, office paper is the main application of recycled paper. People refuse to accept recycled paper because of its own defects: insufficient whiteness, insufficient surface fineness and so on. Experts stressed that there is a certain limit to the whiteness of paper accepted by the human eye. If the whiteness of paper is too high, it will cause certain damage to the eyes. In this sense, using recycled paper as office paper can even strengthen our vision health care. The state stipulates that the whiteness of book paper with high attention intensity, such as teaching books, shall not exceed 70%. Therefore, many people are not picky about the low whiteness of recycled paper

in the interview, we learned that at present, there is no special organization in China to manage waste paper recycling and coordinate the application of recycled paper. Therefore, in addition to investing funds, establishing standards, unblocked channels and changing ideas, we must first solve the management problems. Only when someone takes care of them, can the problems that restrict the promotion of recycled paper listed by us be effectively solved
