A lot of papermaking waste paper recycling progress

Nowadays, the recycling and utilization of waste paper is very important in the world to reduce the demand for fiber raw materials. For example, the United States is the country with the highest paper production in the world, with forest area second only to Russia and other countries. However, from the 1940s, the United States began to pay attention to the recovery and utilization of waste paper. By the 1990s, the United States not only used paper in large quantities in domestic waste paper, but also exported excess waste paper. In the past, the newsprint used in the United States was provided by Canada. In recent years, due to the use of waste paper to make newsprint, the output has continued to increase, reducing imports.

As the United States strongly promotes the recycling of waste paper, it promotes enterprises to use waste paper to produce cardboard and packaging materials. For example, the US stone container company uses waste paper to produce cordeck corrugated flat plates for packaging and transportation of goods; R-Tech company produces E-cubes packaging materials made of recycled waste paper, and can be packed into fragile after adding fillers. Compared with foam plastics, the articles are more convenient and quick to use in filling, can fill any shape of goods, can be recycled, biodegradable, and non-toxic. Longview Fiber Company of the United States has launched a new high-quality hand bag that is made from waste paper, biodegradable and conducive to environmental protection. For the future development, the United States has proposed that the utilization rate of waste paper should reach 50% of the paper production. Among them, newsprint reaches 60%-70%; printing paper reaches 40%-50%; toilet paper should use waste paper as raw material.

Finland is rich in forest resources. Forests account for more than 70% of the country's land area and export a large amount of wood pulp fibers each year. In spite of this, in 1990 they also began to pay attention to the recovery of waste paper, reaching 50-600,000 tons per year.

Japan's paper production is second only to the United States. In recent years, Japan's paper and paperboard production has shown a trend of increasing year by year. In 2001, its output was 30.717 million tons, which was 1.1 times that of 1990. During the 11 years from 1990 to 2001, the discretionary consumption of Japanese wood pulp remained basically the same, because waste paper has become the main raw material of the Japanese paper industry. In 2001, waste paper accounted for 58% of Japan's raw materials for paper and board production.

In addition, the annual utilization rate of waste paper in Germany, the Netherlands, and South Korea is about 50% of the output.
