The gap between Chinese and foreign waste paper treatment and Its Enlightenment

waste paper recycling not only has good economic benefits, but also directly relates to major issues of the national economy and the people's livelihood, such as environmental governance and resource protection. The recycling of waste paper in some advanced countries in the world has reached a considerable level both in terms of scale and production technology. China is also striving to catch up with the level of developed countries. This paper analyzes the waste paper treatment at home and abroad

waste paper recycling and treatment methods in Switzerland

classified recycling of waste paper and paperboard has been implemented in Switzerland for decades, and most citizens have become accustomed to it. The most common collection method is that people tie up waste paper and put it by the door at a specified time, and then wait for a special organization to collect it. It is also common in some areas to send waste paper to recycling points set up in villages and towns

the collected waste paper and paperboard are either directly sent to the paper or paperboard processing plant, or sorted according to the quality level in advance in the classification organization of a new product development direction proposed by covestro. Because the quality of these waste papers can not fully meet the needs of Swiss recycling paper mills, a large number of waste papers are exported and some waste papers that cannot be collected by classification in China are imported

the collection of waste paper is mainly the responsibility of local governments, with the participation of some associations and organizations, such as the Swiss paper recycling organization, the Swiss pulp, paper and paperboard Association, the Swiss waste paper trade association, the Swiss Corrugated Paper Industry Federation, and paper and paperboard factories

the funds for waste paper collection and treatment in villages and towns mainly come from government taxes or charges for domestic waste, which is inconsistent with the principle that Swiss "polluter pays" for round specimens 1 should be tested in V-shaped grooves. Moreover, because the price of paper/paperboard in the world fluctuates greatly, it is difficult to predict the change of collection cost. Local governments bear a heavy financial burden for the collection and disposal of waste paper. At present, Swiss associations representing towns, cities and villages are promoting the establishment of a system for collecting processing fees in advance. The federal government is drafting a decree for this purpose

waste paper treatment in Germany

although Germany lacks fiber resources and imports a large amount of commercial pulp and paper every year, due to large consumption and high waste paper recovery rate, a large number of waste paper are exported every year. Germany is the second largest exporter of waste paper in the world. In 2004, the output of waste paper and paperboard was 33.253 million tons and the consumption was 35.071 million tons; 22.36 million tons of waste paper were recovered, with a recovery rate of 73%; In the same year, the net export of waste paper was 6.307 million tons, accounting for 28% of the total recovery

under the jurisdiction of EU competition regulations, the German two-way system recycling organization will be forced to open the bidding rules for packaging waste recycling contracts to EU countries. The organization gives an annual subsidy of 50million euros to waste paper collectors, and the cost is paid by the German national green dot marking system in the annual income. The EU has required it to be open to group subscribers operating packaging waste business in other EU countries. At present, relevant institutions are conducting research on the text of the new contract terms drafted by them in order to put forward opinions on the reduction of the amount of subsidies given by paper packaging recyclers

waste paper treatment in Australia

the composition of paper fibers in Australia has begun to accelerate in structure to extract fibers from waste paper

to increase the proportion of recycled fiber in Australia, including some waste paper processing enterprises, will be subject to additional pressure from the waste paper market. When the market demand is strong, it becomes very difficult to sort the mixed waste paper recycled on the street quickly to meet the sales requirements. In order to regulate the market recycling of local waste paper, the Australian Legislative Council, on the one hand, requires local residents to consciously separate packaging paper, newspapers and magazines, on the other hand, organizes personnel to screen the recycled waste paper. However, it is found that the former is very difficult to implement, while the latter is expensive. Therefore, the management department has to reconsider the feasibility of the concept of "resource regeneration and recycling" promoted by the market in reality. Due to the high cost of sorted waste paper, its sales price can not meet the cost requirements, so many people began to look for new ideas such as "garbage power generation"

current situation of waste paper treatment in China

the utilization and treatment of waste paper in China were used to make or prepare toilet paper and low-grade cardboard after simple cooking, dredging, beating and washing in the 1970s. By the 1980s, the recovery rate of waste paper had reached about 25%, and deinked pulp could be produced in many manufacturers. After the heating was interrupted in the 1990s, some large and medium-sized paper-making enterprises have successively introduced deinking equipment and technologies including production lines from abroad, and made targeted improvements and innovations on waste paper deinking agents and waste paper deinking equipment, so that China's waste paper utilization and treatment technology and equipment assembly level can be comprehensively developed

some large-scale cardboard production enterprises use deinking equipment and technology imported from imported waste paper to produce high-grade products. For example, Shanghai Hongwen Paper Co., Ltd., Fujian Qingzhou Paper Mill, Liaoyang industrial Paperboard Factory, Anhui Wuhu Dongfang Paperboard Factory, etc. use the imported waste corrugated boxes and the recycled pulp treated by the thermal dispersion method or the cold screening method as the core and bottom pulp to produce Kraft linerboard and papermaking bag paper on the imported production line or the original imported paper machine, which not only has high quality and grade, Moreover, the imported old corrugated paper containing adhesives and impurities that affect production and are easy to cause paper diseases can also be effectively treated to ensure the normal operation of the production line. The enterprises represented by Guangzhou Paper Co., Ltd., Zhonghua Paper Co., Ltd. and Fujian Nanping Paper Co., Ltd. respectively introduced deinking production lines or main equipment from abroad, and adopted the comprehensive flotation washing law to deal with old newspapers and magazines. Guangzhou paper mill and Fujian Nanzhi Co., Ltd. make paper with recycled pulp. However, Ningbo Zhonghua Paper Co., Ltd. used recycled waste paper pulp as core pulp and bottom pulp to produce coated white paperboard, which achieved better results

some domestic research and production units have cooperated to research and develop deinking technology and equipment. After innovation with the existing conditions of the enterprise, the production of small batch of recycled pulp of waste paper has been successful. Manufacturers in Xuchang, Jiaozuo, suixian, Xinxiang and other places in Henan Province use imported OCC and other waste paper to prepare high-strength corrugated paper and carton board with remarkable results. Fuzhou No. 2 paper mill, Nanning Xinyang paper mill and other small and medium-sized enterprises produce toilet paper and low-grade whiteboard by using domestic equipment and technology to dispose of old newspapers and cardboard. Hebi paper mill in Henan Province has slightly reformed its original equipment to produce recycled paper from old newspapers. The paper street in Xuchang and Yanshi uses waste paper to produce raw paper worth more than 100billion yuan by 2020. Some paper mills in Xinmi City have made good profits in using domestic old paper to produce medium and low-grade products such as carton board and kraft face paper

domestic equipment manufacturers and chemical production and research units have achieved good results in equipment performance and chemical quality through cooperation. For example, Hangzhou Light Industry Research Institute has developed a small waste paper treatment process and waste paper deinking system. The waste paper treatment equipment researched by Liaoyang paper machinery plant and Fujian Light Industry Machinery Plant has formed a supporting system and has been successfully put into production. Some paper machinery factories in Shandong have also produced different types of deinking equipment, which have been purchased and used by manufacturers. In addition, various deinking agents developed by Fujian paper research institute, Hangzhou Institute of chemical industry, Tianjin University of science and technology and other units have also been recognized by users

some inspirations

(1) strictly control the purchase of waste paper raw materials. In particular, the import of waste paper, in the current situation of more supply channels, we should be more cautious. The enterprise must conduct a comprehensive investigation on the waste paper suppliers to understand the source of supplies, economic strength and reputation, so as to avoid being cheated

(2) enterprises with strong financial and technical strength can also introduce foreign existing deinking technologies and equipment, including production lines, to produce high-quality recycled pulp and high-grade products while purchasing foreign old corrugated boxes, old magazine paper and old paper. For enterprises that have already recovered straw pulp alkali, they can also use imported waste paper recycled pulp to add straw pulp and commercial wood pulp, and prepare cultural paper in proportion

(3) for paper mills that have been shut down or have no hope of pollution control, a small amount of money can be invested to slightly improve the original equipment, and domestic waste paper can be used to produce low-grade toilet paper, ordinary corrugated paper or recycled paper. Domestic and imported waste paper can also be used to copy high-end products, which will be possible to get out of the dilemma

(4) when purchasing waste paper, enterprises should use it by classification in combination with their own equipment conditions, technical strength, production varieties, etc. The imported corrugated boxes and AOCC waste paper can be used to produce high-grade carton board, high and medium grade corrugated paper and paper bag paper, or used as the core pulp and bottom pulp for the production of white paperboard; Using waste newspaper and 30% old magazine paper, after flotation washing comprehensive 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 to produce high-grade cultural printing paper on improved paper machines or imported production lines. The purchased domestic waste paper can be used to produce medium and low grade cardboard and toilet paper. At the same time, attention should be paid to the use of chemical additives to make up for the lack of physical strength of paper products. Through the above analysis, it is not difficult to see that although China's waste paper treatment capacity has been greatly improved, there is still a big gap compared with developed countries. Relevant departments should take effective measures to make waste paper more efficient in utilization
