Paper recycling, what you should do

the impact of the printing industry on the environment cannot be ignored. Paper is the largest consumption of consumables in printing plants. In order to truly realize environmental protection printing in China, we must first start with paper. Printing plants and production plants should also make full use of their talents to improve enterprise efficiency and realize green printing through paper recycling

printing enterprises: sound paper management system

printing plants should have a complete paper system before and after printing paper. If you can make good use of waste paper instead of discarding it, you are likely to earn more income - perhaps twice as much as before. A sound paper management system includes:

(1) accurate inspection and measurement means and complete original records, which can correctly calculate and assess paper consumption and savings

(2) the paper consumption quota shall be verified by the competent department

(3) the paper used for printing books and periodicals shall be used and increased according to the requirements of the notice issued by the publishing house, so as to save all kinds of paper on the premise of ensuring the quality and quantity of products

(4) the saved paper should be checked and accepted regularly

(5) use information software to make an account of the paper residues cut out in production, which is convenient for use

and enjoy independent intellectual property rights (6) greasy waste paper, waste book pages, waste sealing paper, etc. lost in printing shall not be burned at will, but shall be collected and stored, and uniformly sent to the paper mill for recycling

(7) sell paper edges, paper heads, leftovers, etc. cut during printing and binding

in addition, in order to mobilize employees' enthusiasm for recycling paper, workers can also develop a set of incentive mechanisms, such as giving bonuses to encourage savings, which are extracted from the sold waste

in foreign countries, some powerful printing plants will establish large-scale waste recycling systems, install large-capacity self-propelled machines and conveyor belts, and cut waste collection systems as their business volume increases

paper manufacturers: improve the technical content and profit of paper

(1) enterprises with strong capital and technical force can also introduce foreign existing deinking technology and equipment, including production lines, to produce high-quality recycled pulp and high-grade products while purchasing foreign used corrugated boxes, used magazine paper and used paper

(2) when purchasing waste paper, enterprises should classify and use it in combination with their own equipment conditions, technical strength, production varieties, etc. Imported corrugated boxes and AOCC waste paper can be used to produce high-grade box board paper, high and medium grade corrugated paper and paper bag paper, or as the core pulp and bottom pulp material for the production of white board paper; Using waste newspapers and 30% old magazine paper, after deinking, paper can be produced or used as the core pulp and bottom lining pulp of white paperboard; Using imported office waste paper, such as copy paper, computer printing paper, etc., select new deinking methods, and produce high-end cultural printing paper for storage in the oil tank in the improved paper machine or the imported production line. The purchased domestic waste paper can be used to produce medium and low-grade box paperboard and toilet paper. At the same time, attention should be paid to the use of chemical additives when using waste paper to make up for the lack of physical strength and other indicators of paper products

in some developed countries, waste paper classification standards have reached 40 ~ 50. High quality waste paper makes high-grade recycled paper, such as writing paper and printing paper; Low quality waste paper makes low-grade recycled paper, such as newspapers and cartons. In contrast, domestic waste paper has only two major classification methods: newspaper and waste paper, which contain less wood pulp components and more impurities. In order to increase the weight and price, some illegal traders even deliberately watered and mixed garbage on bundles of waste paper, making it more difficult to regenerate waste paper

(3) make full use of chemical additives. We should focus on the development and research of new deinking agents, enhancers, bleaches and detergents, and form a complete application process to avoid secondary pollution and further improve the use value of waste paper

(4) domestic machinery manufacturing and chemical production wood flour infinite reduction manufacturers, together with papermaking enterprises, scientific research institutes and other relevant units, jointly develop advanced deinking equipment and deinking agents, enhancers and other chemicals, constantly improve the level of equipment and equipment for recycled papermaking with waste paper and the adaptability of paper varieties, and promote the rapid development of waste paper utilization

make good use of waste paper

if we start from the national conditions of waste paper recycling in China, domestic waste paper can be roughly divided into the following 11 categories

waste newspaper this kind of waste paper is mainly used to produce recycled paper, and can also be used to produce household paper, general cultural paper or general printing paper

white newspaper this kind of waste paper belongs to high-grade waste paper, which can be used to produce recycled paper, high-grade cultural paper or high-grade printing paper

waste magazines this kind of waste paper mainly includes books that are not issued by printing plants or bookstores and recycled after issuance, waste publications and books that do not contain or only contain a small amount of mechanical pulp. After deinking, this kind of waste paper can be used to produce glossy paper, writing paper, relief paper, toilet paper, etc. after removing color and etching ink, it can also be used to produce paperboard, or mixed in paper

white paper edge of publications this kind of waste paper belongs to post industrial waste paper, mainly the white paper edge cut by the printing plant, and a small part of it is unprinted writing paper such as organs and schools. White paper edge is an ideal substitute for pulp. It can replace bleached pulp and be used to produce high-grade cultural paper. Therefore, this kind of waste paper can also be directly used

waste kraft paper this kind of waste paper is post consumption waste paper, mainly refers to waste kraft paper and waste paper bag paper. This kind of waste paper can be recycled and recycled striped wrapping paper after stripping and selection

waste corrugated box this kind of waste paper includes corrugated board and corrugated box, etc. This kind of waste paper has the largest recycling capacity and can be used for recycling box board paper, corrugated base paper, etc. Among them, bamboo pulp waste paper and wood pulp waste paper can also be used to produce vermicelli cardboard

waste packaging paperboard this kind of waste paper includes non corrugated paperboard and cartons, which can be recycled for the production of paperboard

carton trimming this kind of waste paper is mainly used to produce cartons and paperboards

office waste paper this kind of waste paper mainly includes used printing paper, electrostatic copy paper, fax paper and other office paper. With the increasing modernization of office equipment, the number of office waste paper is increasing year by year, so office waste paper has become a new kind of waste paper with great potential

special waste paper this kind of waste paper is a kind of waste paper after special treatment, so its reuse process is different from other waste paper

mixed waste paper this kind of waste paper is the unsorted waste paper left after sorting, and it should be recycled after removing the impurities as much as possible

mixed waste paper is a kind of low-grade waste paper, including a part of garbage waste paper, which is mixed with waste newspapers, waste magazines, waste books, waste exercise books, office waste paper, advertising color pages, shredded paper and packaging items. It is mainly used for making linoleum base paper, wallpaper, moisture-proof paperboard and other low-grade paperboard

enterprises and the government coordinate with each other

in Japan, there is a company specialized in recycling waste paper, which is composed of three companies, namely, Xutian Store Co., Ltd., Daiwa paperboard Co., Ltd. and Dashan Industrial Co., Ltd., among which Xutian Store Co., Ltd. has been engaged in waste paper recycling and is a leader in the industry; Both Dahe paperboard and Daxian Xingye are engaged in papermaking. At first, the reason for their cooperation was that they had the same idea that if the generated waste could be recycled and used in this industry, it would save costs while protecting the environment. Therefore, they worked together to form the "Daiwa Daisan group" company, which specializes in waste paper recycling and recycling

first, they will collect waste paper from printing plants, newspapers, and even homes of all sizes, concentrate on Xutian Store Co., Ltd. for regeneration, and then (5) the uncertainty U5 introduced by the resolution of the calibration tensile testing machine Put the waste paper into a cleaner operated by the rotation of the washing machine, and stir the waste paper into pulp, during which the coarse substances in the pulp will be discharged through the bottom of the machine; Then the pulp is injected into the disintegrator, rotated at a high speed, the fibers in it are isolated, and then the low concentration decomposition solution is added. The fine particles still existing in the screened pulp are decomposed again to ensure that the texture of the recycled paper will not be too rough. Finally, a small amount of detergent is added, cleaned and watered, and then the treated pulp is dried to become a material that can be used for papermaking. Then these materials will be sent to Daiwa paperboard and Dashan Industrial Co., Ltd. for processing to make reusable paper

Prince paper, which accounts for one third of Japan's paper supply market, is also engaged in related work. In order to improve the quality of recycled paper, Prince paper added dip waste paper deinking pulp equipment to increase the whiteness of recycled paper. The "hoxyby nepia" series of paper made by Prince paper has different percentages of recycled paper components, including 100% recycled paper and only 50% recycled paper, which are suitable for the needs of different customers
