The use of recycled paper products can protect the earth and eyeballs

just as the new Harry Potter and the Half Blood Prince by British female writer J.K. Rowling is selling well in major bookstores, an environmental protection organization alliance called "market creation" recently called on American consumers to boycott the American version of Harry Potter 6 and buy the novel from Canadian Publishers. The reason is that the book was not printed on reusable paper by us publishers

environmental protection and energy conservation have become the focus of the world

recycled paper is an environmentally friendly paper product.

recycled paper is the paper produced from used paper products through multiple processes such as recycling and sorting. The proportion of waste paper pulp in its raw materials is 60%~100%, and its color is darker than that of ordinary paper. The paper is usually printed with a "recycling mark" surrounded by three curved small arrows. The whiteness of recycled paper is not high, only 82-85 degrees, while the whiteness of raw wood pulp paper can reach 95-105 degrees. At present, 83 degree natural color recycled paper is the most popular in the world, because the natural color recycled paper can protect two balls - the earth and the eyeball

as an environmentally friendly paper product, the production of recycled paper is equivalent to indirectly cutting down fewer trees and protecting the forest. It is understood that each ton of waste paper recycled can save 3 cubic meters of wood, 100 tons of water, 300 kilograms of chemical raw materials, 1.2 tons of coal and 600 degrees of electricity. Every ton of recycled paper produced is equivalent to protecting 26 big trees

China's recycled paper has not been fully recognized by the public.

at present, China's output and consumption of paper and paperboard rank second in the world. However, China's forest coverage is 10 percentage points lower than the world average, only 16.55%. Since the implementation of the natural forest protection project in 1998, the cutting of domestic wood has been more restricted. This reality determines that the domestic wood fiber supply will show a downward trend

recycled paper produced by using urban waste paper as raw material instead of commercial wood pulp can be used to replace ordinary office paper. In some developed countries, the recycling rate of waste paper is as high as 60%. However, in China, how to solve the problem of waste paper in cities has not been fully utilized, and recycled paper, especially office recycled paper, has not been fully recognized by the public

according to relevant data, China's paper consumption is about 35million tons per year. Based on one third of the waste, more than ten million tons of waste paper can be recycled each year, but the actual recycling rate is not high. Taking Beijing as an example, 1.1 million tons of waste paper are produced every year, and only 100000 tons are actually recycled, with a utilization rate of less than 10%. It is estimated that if half of the office paper used in the world is recycled, 75% of the demand for new paper can be met, equivalent to 8million hectares of forest protected from deforestation

in addition, it is understood that compared with ordinary office paper, recycled paper has the most characteristics, physical properties and food packaging in the field of film utilization. The type III sample is only applicable to the determination of the tensile strength of molded chopped glass fiber reinforced plastics. In addition, recycled paper has good stiffness, good inking effect and can be dyed into various colors and lines after treatment. Therefore, a large number of recycled paper are not only printed into business cards, It is also widely used to make student papers, office documents, bids and other written materials and book covers. In addition, there are invitations, greeting cards, clothing tags, etc
