The paper industry is an industry that has a close relationship with resources and the environment. As far as water is concerned, the paper industry in China is a large water user and the amount of water required for production is large.
On average, China's paper industry produces one ton of paper per year, which requires 100 cubic meters of water, while foreign paper mills consume only 10 to 20 cubic meters of water per ton of paper, and even less than 10 cubic meters.
For the pulp and paper conglomerate, the water consumption per ton of pulp and paper in China is as high as 300 cubic meters, compared with 35-50 cubic meters in foreign countries.
China also has tons of paper water consumption at an advanced level, such as the Shanghai Hansong potential paper industry, with an annual output of 120,000 tons of high-quality newsprint, all using waste paper as raw materials, and the daily water use during production is 14,000 cubic meters, of which the amount of clean water is generally It is 0.7-0.9 million cubic meters per day and the average water consumption per ton of paper is 20 cubic meters.
The per capita water supply in China is only 1/4 of the world average, ranking 58th in the world. Due to the continuous increase in population and rapid economic development, our freshwater resources will become even more in short supply.
How to reduce the water consumption per ton of paper in China's paper industry as soon as possible is not only beneficial to reducing the cost of paper mills, but also is a major responsibility for future generations.
