Waste paper market recycling

Actively and Effectively Utilizing Foreign Resources As foreign waste paper is mainly wood fiber, it can be seen from the amount of waste paper imported and used in 2000 that there were differences in total waste paper imports and waste paper imports in 1999 compared to 1999. The degree increased, with total waste paper increased by 47.6%, from 2.51 million tons in 1999 to 3.71 million tons in 2000. Imported waste paper exchanges increased from 245 million U.S. dollars to 550 million U.S. dollars, an increase of 127%. Among the 4 types of waste paper used by customs statistics, the import volume of bleached printed waste paper increased the fastest, with imports increasing by 326,000 tons. 84.5%, the import volume is the largest, including mechanical pulp waste paper (old newspapers), accounting for 1/2 of all imported waste paper, reaching 1.8 million tons in 2000. Contains mechanical wood pulp waste paper 146.1 US dollars / ton, an increase of 47.7 US dollars / ton, other waste paper 143.8 US dollars / ton, an increase of 45 US dollars / ton, in 2000 as a whole compared with 1999, waste paper prices are volatile upstream.
The use of high-tech and advanced equipment in today's world pulp and paper technology to reduce pollution, save energy, water resources and full use of fiber renewable resources and other aspects of development. In recent years, a group of enterprises with strong capital and technical strength in China have adhered to the use of advanced waste paper processing technologies at high starting points, high standards, and high levels, and introduced internationally advanced equipment, striving to keep up with the international trend of large-scale production of paper industry in the short term. . Since the reform and opening up, China has imported more than 50 sets of waste paper processing lines from abroad, including unbleached kraft paper and corrugated paperboard waste paper, waste newspapers, bleached printing paper waste paper, and other waste paper processing equipment. The largest waste paper production line has a daily production capacity. Reach 500 tons. These imported equipment are necessary to speed up the use of waste paper in China. It has greatly reduced the gap between China's waste paper processing technology and equipment and the world's advanced level. Nowadays, almost all advanced equipment for waste paper processing in the world can be used in Chinese enterprises. see.
Secondary pollution in the process Although waste paper pulp and paper can reduce pollution, the pollution of waste paper in the deinking process is still serious. In recent years, China has imported several sets of waste paper deinking wastewater treatment equipment from abroad. All of them are air flotation methods. The flocculation and sedimentation method developed by South China University of Science and Technology has been applied in papermaking enterprises in Guangdong and Shandong. The white water recovery device has many models and it is widely used and it works well.
The “classification standard for waste paper recycling” is based on the collection of waste paper, and the varieties are mixed. However, some advanced countries in the world have formulated relevant standards for waste paper recycling classification. With the strengthening of China’s awareness of social environmental protection, more and more Many paper mills use waste paper to replace some wood pulp and straw pulp to produce various kinds of paper and paperboard, in order to reduce costs and reduce the emission of pollutants. Therefore, it is imperative to formulate China's “classification standard for waste paper recycling”. With the approval of the Ministry of Science and Technology, the China Pulp and Paper Research Institute will undertake this research. The research fee will use a special fund for social charity research and it is planned to be completed within two years. The above research work has been carried out.
Strengthening the recovery, classification and supply of domestic waste paper In recent years, the issue of waste paper sorting and recycling has attracted the attention of relevant departments. Beijing Municipality will publish the “Administrative Measures on Recycling Resources Recycling Industry in Beijing”. In 1998, Shanghai imported 1.23 million tons of waste, of which waste paper accounted for 70%, that is, 870,000 tons of imported waste paper, plus about 700,000 tons of waste paper for local recycling. Shanghai already has the conditions for industrialization. In order to speed up the development of waste paper recycling and utilization and promote the conversion of waste paper into usable materials, Shanghai Paper Company has established an integrated waste paper recycling and processing plant, which is of great significance to the development of the paper industry in Shanghai.
