1. Using recycled fiber to make paper can greatly reduce the consumption of trees, water and electricity and the emission of pollutants. According to experts, recycling one ton of waste paper can produce 0.8 tons of recycled papermaking fiber, which can cut down 0/7 trees and save 3 cubic meters of landfill space.
2. In foreign countries, waste paper is called forest resources in cities, because it is waste newspapers, books and periodicals, office paper, kraft paper, cartons, corrugated paper and so on. , is a valuable fiber raw material.
3. Waste paper papermaking has the advantages of low energy consumption, low environmental treatment cost and low unit raw material cost. In China, the production of newsprint with waste paper can reduce the production cost by 300 yuan/ton compared with that with virgin wood pulp, and also can reduce environmental pollution. Therefore, people call paper and cardboard produced with recycled fibers green products.
4. Using waste paper as a resource can achieve a win-win situation of saving and environmental protection.
What are the benefits of waste paper recycling? Most of the paper used in China's culture and industry comes from wood. Theoretically speaking, taking the total paper consumption in China in 2002 as 35 million tons, maximizing the production and use of environmentally-friendly recycled paper with cultural and industrial waste paper as raw materials is equivalent to saving a Daxinganling in 20 months. Therefore, actively participating in "recycling waste paper" and "actively using recycled office paper" are the national policies to implement sustainable development and promote circular economy.

It was learned from Beijing No.7 Paper Factory that 1 ton of recycled office paper can be produced with1ton of cultural waste paper as raw material. According to international standards, it can save 4 cubic meters of wood, water 100 cubic meters, electricity 600 kWh, coal 1.2 tons, 300 kilograms of chemical raw materials, waste residue treatment fund 150 yuan, waste residue landfill land, avoid the pollution of landfill waste residue to surrounding groundwater, and produce 3 cubic yards of solid waste and 60 pounds of industrial waste gas. According to China's standards, it will save more. Based on an annual output of 50,000 tons of recycled paper, the factory can save 5 million cubic meters of water and 200,000 cubic meters of wood.
There are many successful examples of "waste paper recycling".
A, 1993, President Clinton of the United States issued an executive order, requiring all levels of * * * to use 80% recycled office paper, and included this work in * * * procurement. By 1999, the recycled office paper used by American federal agencies has reached 98% of the total office paper. California has enacted the Waste Paper Utilization Act for recycling and using recycled paper. At present, 13 states in the United States have enacted similar laws. Germany requires the paper industry to use waste paper as raw material, and since June 2000, 65438+1 October1,it has been 60%.
B Tokyo, Japan promotes the benefits of recycling waste paper by entertaining residents to watch movies about recycling and recycling waste paper for free. Officials mobilized employees from all walks of life and primary and secondary school students to voluntarily recycle waste paper and repackage garbage. In Osaka, Japan, when recycling waste paper, a lottery ticket is given every 10 kg, and if you win the lottery ticket, you will get a generous reward. Following the promulgation of 1992 Circular Economy Law, Japan revised the Circular Society Law in 2000 and formulated a series of implementation regulations after continuous improvement.
C, France, Belgium and other countries also promulgated laws to develop circular economy in 1990s, including the utilization of waste paper resources.
D. Since 2002, Taigelin Paper has introduced the world-advanced deinking pulp production line for waste paper, and now the annual consumption of waste paper exceeds 6.5438+0.5 million tons. Waste paper recycling has become a very important part of the company's "eco-circular economy industrial chain".
E. Through unremitting efforts, American Paper Source Company has recovered and reused 65,438+0,000% of the waste, realizing the so-called "from cradle to grave" recycling. It is for this reason that in March 2005, American Flexographic Printing Technology Association awarded them the "Outstanding Contribution Award for Environmental Protection of the Year".
In fact, if you think about it, it takes many years for a big tree to grow, and it only takes a few minutes to cut it down! Paper industry is an industry that consumes a lot of natural resources. How to take the future road of paper industry is related to the construction of a harmonious society in China. We should cherish every forest resource and make our environment full of green.
What are the advantages of recycling old refractory bricks? Refractory bricks can be fully and effectively utilized, which can not only reduce the exploitation of refractory mineral deposits, reduce the production of refractory raw materials, reduce the cost and energy consumption in the preparation process, but also save the transportation cost of refractory raw materials, which is conducive to resource saving, energy saving and environmental protection.
Where is the waste paper recycling factory in Guangxi? There is a paper mill on Dongxing Old Road in Fangcheng, recycling waste paper! Just got back from Fangcheng to Dongxing (Old Road) Shui Ying intersection!
How to recycle waste paper in life? In 1970s, the utilization and treatment of waste paper in China was to make toilet paper and low-grade foil through simple cooking, defibering, pulping and washing. By the 1980s, the recovery rate of waste paper reached about 25%, and a few manufacturers could also produce deinked pulp. After entering the 1990s, some large and medium-sized papermaking enterprises introduced deinking equipment and technology from abroad, including production lines, and made targeted improvements and innovations in waste paper deinking agents and waste paper deinking equipment, which fully developed the waste paper utilization and treatment technology and equipment assembly level in China. Some large cardboard production enterprises use imported waste paper and imported deinking equipment and technology to produce high-grade products. For example, Shanghai Hong Wen Paper, Fujian Qingzhou Paper Mill, Liaoyang Industrial Paperboard Factory, Anhui Wuhu Oriental Paperboard Factory, etc. Using imported waste corrugated boxes and recycled pulp treated by thermal dispersion method or cold screening method as core pulp and bottom pulp, kraft liner board and bag paper are produced on imported production lines or original imported paper machines. Not only the quality and grade are high, but also the adhesives and impurities that affect the production and easily cause paper diseases in imported old corrugated paper can be effectively treated to ensure the normal operation of the production line. Enterprises represented by Guangzhou Paper Co., Ltd., Zhonghua Paper Co., Ltd. and Fujian Nanzhi Paper Co., Ltd. introduced deinking production lines or main equipment from abroad respectively, and used flotation-washing comprehensive method to treat old newspapers and magazines. Guangzhou Paper Mill and Fujian Nanzhi Co., Ltd. use recycled pulp to make newsprint. However, Ningbo Zhonghua Paper Co., Ltd. used recycled waste paper pulp as core pulp and bottom pulp to produce coated white board, and achieved good results. Some domestic research units and production units cooperated to develop deinking technology and equipment, and after making use of the existing conditions of enterprises to innovate, small-scale production of waste paper recycled pulp was successful. Manufacturers in Xuchang, Jiaozuo, Suixian, Xinxiang and other places in Henan Province used imported waste paper such as AOCC to make high-strength corrugated paper and paperboard, and achieved remarkable results. Small and medium-sized enterprises such as Fuzhou No.2 Paper Mill and Nanning Xinyang Paper Mill use domestic equipment and technology to process old newspapers and old cardboard to produce toilet paper and low-grade white cardboard. Henan Hebi Paper Mill slightly modified the original equipment and used old newspapers to produce recycled newsprint. Xuchang, Yanshi papermaking street, using waste paper to produce toilet paper. Some paper mills in xinmi city use domestic old cartons to produce middle and low-grade products, such as box board, cowhide linerboard and so on, and have achieved good benefits. Domestic equipment manufacturers and chemical production research units have achieved good results in equipment performance and chemical quality through cooperative research. For example, Hangzhou Institute of Light Industry has developed a small waste paper treatment process and a waste paper deinking system. The waste paper treatment equipment researched by Liaoyang Paper Machinery Factory and Fujian Light Industry Machinery Factory has formed a series of supporting equipment and has been successfully put into production. Some paper machinery factories in Shandong have also produced different types of deinking equipment, which are purchased and used by manufacturers. Various deinking agents developed by Fujian Paper Research Institute, Hangzhou Chemical Research Institute and Tianjin University of Science and Technology have also been recognized by users. The insiders put forward some suggestions on how to recycle waste paper reasonably: 1. Strictly control the procurement of waste paper raw materials. Especially imported waste paper, we should be more cautious in the current situation of more supply channels. Enterprises must conduct a comprehensive inspection of waste paper suppliers to understand the source of goods, economic strength, reputation and so on, so as not to be deceived. 2. Enterprises with strong financial and technical strength can purchase old corrugated boxes, old magazine paper and old newsprint from abroad, and at the same time, they can also introduce existing deinking technologies and equipment from abroad, including production lines, to produce high-quality recycled pulp and high-grade products. For enterprises that recycle straw pulp alkali, they can also use recycled pulp from imported waste paper, and add straw pulp and commercial wood pulp in proportion to make high-grade cultural paper. 3. For paper mills that have been shut down or have no hope of pollution control, you can invest a small amount of money to slightly improve the original equipment and use domestic waste paper to produce low-grade toilet paper, ordinary corrugated paper or recycled newsprint; You can also use domestic and imported waste paper pulp to copy medium and high-grade products, which will probably get out of the predicament. 4 enterprises in the procurement of waste paper, should be combined with their own equipment status, technical strength, production varieties and other classified use. Imported corrugated boxes and AOCC waste paper can be used to produce high-grade cartons, high-grade corrugated paper and bag paper, or used as core pulp and bottom pulp raw materials for white cardboard production; Using waste newspaper, adding about 30% old magazine paper, after comprehensive deinking by flotation-washing, newsprint can be produced or used as core pulp and backing pulp of white board. Use imported office waste paper, such as copy paper and computer printing paper. By using new deinking method, high-grade cultural printing paper can be produced on improved paper machine or imported production line. The purchased household waste paper can be used to produce middle and low grade cardboard and toilet paper. At the same time, when using waste paper recycled paper, we should pay attention to using chemical additives to make up for the lack of physical strength of paper products.
Who knows that the recycling method of waste paper is to make paper after crushing?
What are the advantages of using waste paper to produce recycled paper? The reuse of resources not only reduces environmental pollution, but also avoids asking for more resources from nature again, which has a great protective effect on the environment.
Does the discarded wallpaper have recycling value? Unless it is pure paper, it has no use value. In addition, there are few wallpaper made of pure paper.
What's the use of waste thermal paper? Is there any way to recycle it? I just produce long-lasting thermal paper consumables. A large number of thermal paper scraps and waste paper are produced every day. Waste heat-sensitive paper is useless, that is, ordinary waste paper is sold to waste collection stations. It's best not to throw it around, after all, there is a layer of chemical raw materials on it, which has certain pollution to the environment. Manufacturers who recycle waste paper must have certain pulping technology.
