Modern forestry is the basis for the development of the paper industry

The international modern paper industry is based on modern forestry. Brazil was a papermaking backward country in the 1950s. 50% of the 150 paper mills were small and medium-sized plants with daily production of 100,000 tons or less, and domestic papers mainly depended on imports. In the early 1960s, the Brazilian government used tax to encourage paper mills and private afforestation. Tax-free special funds were earmarked, and government agencies set up supervision and implementation. In 10 years, from 1967 to 1976, a total of 2.16 million hectares of forest were planted, which increased the production of paper to 2.048 million tons, and increased the production of pulp by 1.266 million tons, which was 2.5 times and 2.8 times that before the change, ending the long-term dependence on imports for paper. . In 1976, Brazilian pulp and paper had exports. Now it is a major exporter of goods. In 1997, it exported 2.385 million tons of pulp.

Before 1950s, Spain was a paper-making country dominated by straw pulp. It had a long-term annual output of 16-18 million tons of paper, with few varieties, poor quality, and serious pollution. The average annual consumption of paper was 6 kilograms. In the 1960s, the government attached great importance to papermaking, and the state and the enterprise combined to produce a large number of eucalyptus trees and set up large-scale paper mills. It took 20 years (1960-1979) to increase paper and paperboard to 2,534,000 tons, and modernized the paper industry.

Japan has a small land area and is equivalent to only half of Heilongjiang Province in China. It has poor resources and the volume of forest area is much smaller than that of China. In the 1960s, Japan produced 4.5 million tons of paper, which was at a time when the economy was booming. There was an urgent need for the paper industry to provide paper and paperboard. Japan lost no time in developing wood-based papermaking. There are two main measures. One is to tap the potential of resources, and the other is to rely on imports. The method for tapping domestic resources is to combine paper mills, forest farmers, and wood processing plants to cut wood residues from waste wood processing in forest areas into wood chips and sell paper to paper mills.

In 1956, Japanese wood chips accounted for only 1% of wood, and since then wood chips have been rapidly developed. Later, with the development of the paper industry, the Japanese wood chip industry also developed simultaneously. Until the early 1970s, Japan produced 12 million tons of paper and paperboard, becoming the second largest papermaking country in the world. The supply of domestic wood chips has risen to more than 50% of domestic materials, or even 60. %.

Wood-based papermaking is the only way for the paper industry to grow and expand. This is true in North America and North Europe. Natural Japan is also lacking in natural forestry resources, Spain, and Spain. China is currently a country with little forestry resources, but it is still better than Japanese conditions. many. As long as we follow the example of Japan and Spain, tap existing resources, increase the overall utilization of wood, and actively plant fast-growing and high-yield forests, the wood needed for papermaking in China is promising.
