The integration of Forest Pulp and paper has become the general trend of the development of the world's paper industry

globally, the world's paper products output has maintained a growth rate of more than 3% in recent years. In 2003, the world's pulp output reached more than 400 million tons, of which wood pulp accounted for 70%, and the output of paper and paperboard was 340 million tons; Seven of the world's top 500 are paper enterprises. The development trend of the world paper industry presents new characteristics

international large-scale pulp and paper enterprises build fast-growing bases for cutting high-yield raw material forests after water cooling and finalization under the action of tractors in various forms, and combine afforestation, forest management, logging, pulping, papermaking and sales, forming a virtuous cycle of industrial chain. The wood raw materials of the paper industry in advanced countries in the world have reached 90%, and more than 95% in the United States, Sweden and other countries. The integration of Forest Pulp and paper is the basis of resource intensification, cleaner production, technology integration, functionalization and economic scale of cold drawn polymer heating branch glass transition temperature products, and represents the main trend of the development of the world's paper industry

resource intensification

at present, the world's advanced production mode of paper industry has realized the transformation from extensive utilization of resources to intensive utilization of resources. More than 90% of the enterprises in the United States, Canada, Finland and other countries, the world's paper powers, have achieved resource intensification, achieved self-sufficiency in raw materials, and production consumption has decreased year by year

cleaner production

at present, papermaking enterprises in developed countries in the world use advanced technology to vigorously implement cleaner production from all aspects of production. For example, in the international advanced chemical wood pulp production, the chemical oxygen consumption per ton of pulp in the sewage discharge of most enterprises is 30 kg to 50 kg, and the biological oxygen consumption is less than 1 kg. Germany adopts the most advanced chemical thermal grinding machinery. It is estimated that by 2025, the closed circulation system of pulping wastewater has achieved zero discharge of pulping wastewater

technology integration

the continuous improvement of the integration degree of papermaking technology is the development trend of the world's papermaking industry. At present, the research and development of cathode materials has become the key to restrict the wide implementation and utilization of such materials. The paper-making enterprises in the world's advanced countries rely on scientific and technological innovation, adjust the technical structure, optimize the allocation of scientific and technological resources, and widely use information, network, automatic control and other technologies to improve the degree of technological integration. Pulping and papermaking equipment has developed towards large-scale, automation and high efficiency

product functionalization

the demand for paper products in the world has changed from quantity to quality, and paper products have developed from single function to multi-function. The market of low-grade book paper, writing paper, packaging paper and paperboard is gradually shrinking, while high-quality offset paper, color book paper, high-grade cultural paper, high-grade production paper, kraft paper and kraft linerboard, coated paper, etc. have become the mainstream demand

economic scale

countries with advanced paper industry in the world have achieved economic scale. At present, the annual average production scale of enterprises in the international paper industry has reached 80000 to 100000 tons, and that of advanced countries has exceeded 200000 tons, with obvious economies of scale. In 2003, the world's top 50 largest paper companies accounted for more than half of the world's paper and paperboard production
