"Actually, you may come into contact with recycled paper every day, but you don't know it." On December 17, Qi Xiaodong, deputy secretary general of the China Paper Association, said in an exclusive interview with this reporter that "Using waste paper is a cost reduction for paper companies. One way to do this is to add 10% or 50% or even 100% of waste paper, which is determined by different market demands."
Recycled paper is made from waste paper, broken, slag-removed, sifted, graded, and then paper produced by paper machine. The proportion of waste paper in raw materials is added according to customer requirements. “Aside from household paper, most of the waste paper can be used for recycled paper. About 80% of newsprint in China is made of recycled paper. Recycled paper can also be made into cultural paper, packaging paper, cardboard, etc. Paper."
"Papermaking is not a technology with high technological content. Since Cai Lunun invented the papermaking process, the process has not undergone much change. Modern papermaking technology has a high technological content due to the adoption of many new technologies. Papermaking can save a lot of raw wood, so there is a saying that more use of recycled paper is equal to planting trees.†Qi Xiaodong said.
Saving 3 cubic meters of wood with 1 ton of waste paper Internationally, the raw material for papermaking is mainly trees, and China's forest coverage rate is 16%, far below the international average of 28%. The use of 1 ton of waste paper can produce good quality recycled paper about 800 to 900 kg, can save 3 cubic meters of wood, while saving 100 cubic meters of water, saving 300 kilograms of chemical raw materials, saving 1.2 tons of coal, saving 600 degrees.
Some companies are trying to make paper from other raw materials. “All the fibers can be made into paper, but the production process may be more complicated and the quality may not be too high. For example, wicker can only be used as mid- and low-end linerboard.†Qi Xiaodong said that the principle of papermaking is very simple, but it is very difficult to seek breakthroughs on raw materials. .
There are also stone papers that once caused quite a lot of attention this year. “How many stones can be used for papermaking? More importantly, the main ingredient of the so-called stone paper is calcium carbonate, which is actually plastic. When they enter the recycling system of plant fiber paper, it will break the original recycling system because plastic and paper reuse. The process is completely different."
"To develop a recycling economy, cutting down trees is a must. In addition to inhaling carbon dioxide and excreting oxygen, trees should also have economic value, such as the production of paper, building materials, furniture, etc." He said, "But we must plant the trees and must be in different regions. Choose the right tree species and increase the annual growth of the tree."
Imported wood pulp is also one of the choices. Shandong's championship paper industry originally used straw pulp for papermaking. Due to the heavy pollution load and environmental pressure, the product quality was not improved. Therefore, the structure of its raw materials was changed and commodity wood pulp was used. The production of 1 ton of paper now uses approximately 800 kg of wood pulp. At the same time, the company's process conditions are set to be able to use waste paper deinking technology to produce, so now can use 100% waste paper to produce recycled paper.
Reduce wastewater discharge by 50%
The papermaking industry is a large water consumer. Producing 1 ton of pulp requires 30 tons (wood pulp) to 150 tons (grass pulp) of water, and China's per capita water volume is only 15% of the world average.
More importantly, the pollution caused by the paper industry accounts for more than 30% of the total water pollution, and it is one of the most polluting industries in China. Since the late 1990s, China's pollution in the paper industry has been rectified, and a large number of small pulp and small paper companies with tons of tons or less have been closed.
Recycled paper can reduce waste water discharge by 50% during the manufacturing process. In particular, the pulping process in the early stage of papermaking can be eliminated, and black liquor with the most serious pollution will not be produced.
However, Qi Xiaodong believes that “the paper industry is a large water consumer and a big emitter. There is not much room for changing this situation. If we want to develop, we need a lot of investment. From lab to pilot to industrialization is a long one. process."
"China's pollution control standards are very high, many times more than in foreign countries. Now many paper-making companies are trying to save energy and reduce emissions, but we have learned to never advocate the pursuit of zero emissions, but to advocate reasonable emissions, standards of emissions, or out of the product may not Environmental protection," he said. "Now, some companies produce only 1 ton of paper and only need 2 tons of water. Nothing left in the paper. This is the transfer of pollutants."
He once visited some paper mills known as "zero emissions" and found that "sewage water is circulated in the workshop and it smells bad in the summer."
In particular, he pointed out that most paper mills in foreign countries are far away from residential areas. The problem in many places in China is that paper mills are too close to residential areas and pollutants cannot be naturally degraded. “It is best to shut down the small plants. The big plants are built away from residential areas. Many pollutants can be naturally degraded.â€
Recyclable waste paper accounts for tens of millions of tons of data each year. It shows that China’s paper consumption in 2009 was approximately 58.69 million tons. Calculated at 1/3 of the waste paper use rate, the annual amount of waste paper that can be recycled and reused amounts to tens of millions of tons. the above.
Recycling of waste paper is much easier than recycling waste batteries and energy-saving lamps. There will be people who collect waste paper near each plot. They will sell waste paper to scrap collection stations, then to baling plants, and finally to paper mills.
Among them, the packaging plant is a link that people are not familiar with. "Packaging plants can make waste paper into standard sizes. Each container can carry 40 tons. If it can not transport 25 tons, it can carry 60 tons after the package is finished." He said that Beijing has about 40 packing plants.
"Now China's paper consumption is about 60 to 70 kilograms per person per year, while the United States' annual per capita consumption is about 270 kilograms, and Europe is about 160 kilograms. The United States' current recovery rate is about 60%, and Europe is about 65%. About 50% in Asia, about 35% in China." Qi Xiaodong said.
As with the waste paper recycling rate, China's recycled paper usage also has great room for growth. Taking Shanghai as an example, under the active promotion of the government, the use of recycled paper in the city was 8 tons in 2003 and 70 tons in 2004, of which 50 tons was used to print the government bulletin. In 2006, the consumption of recycled paper in Shanghai reached 2.2 million tons. Including newsprint, box paper, and cultural paper.
Whether at home or abroad, the use of recycled paper was initially driven by the government. According to the regulations of the paper industry in Germany, the use rate of waste paper should reach 60%; the rate of use of recycled office paper by the US government agencies has reached 98%.
Ordinary people were not very enthusiastic about such eco-friendly papers at first, and lack of knowledge was the main reason. Many people think that recycled paper is made from waste paper. The paper is not hygienic enough and not smooth enough. “Actually, as the process continues to advance, the quality of recycled paper has been greatly improved, and the appearance and use of the paper have become almost the same as those of plain paper.â€
Currently, there is a two-line stationery on the market priced at $2, recycled paper as long as 1.50 yuan, and other recycled paper office products are all one to four percent cheaper than ordinary paper. “The cost of recycled paper is lower than that of plain paper and it is also cheaper to sell in China. Otherwise, it is difficult for anyone to buy it. However, in the United States, recycled paper products are sold more expensively, because this product saves trees, so the price increases. To express encouragement for the production company."
According to the “Global Recycling Paper Market Outlook†released by the United States Resiling Paper Products Consulting Co., Ltd., the global demand for recycled paper will soar to 50 million tons in the next five years, and most of the growth will come from China. “As more people understand and understand recycled paper, as the education and publishing industries begin to use recycled paper on a large scale, the application areas and the number of recycled paper in China will continue to expand.†Qi Xiaodong said.
