Waste paper recycling and circular economy grow synchronously

when it comes to "circular economy", it is impossible not to mention papermaking. Papermaking consumes trees and discharges sewage. If the scale and pollution cannot be well controlled, the forest is difficult to maintain natural replacement, and the water source is unable to purify itself, then for the future, papermaking is a sword of Damocles. Using waste paper as raw material to make new paper can greatly reduce the consumption of wood pulp and the emission of pollutants. The production of paper products per ton can also save 400 kg of coal, 400 kwh of electricity and 300 tons of water. It is a sustainable development measure implemented by some countries using laws

at present, China is the second largest country in the world in the consumption of paper and paper products, and the largest net importer of international paper trade, and the consumption of paper is still growing rapidly. Therefore, building papermaking into a circular industry is of great significance to China's sustainable development and the safe operation of the national economy

but the current situation is somewhat worrying. Although waste paper accounts for a large proportion of China's papermaking raw materials, waste paper mainly depends on imports. While spending a lot of foreign exchange to buy waste paper from other countries such as "American waste", China produces about 14million tons of waste paper every year, but the recycling rate is very low. A comparison shows the gap. The recovery rate of waste paper in Japan is more than 78%; Germany recycles 4million tons of waste paper every year, accounting for 83% of all waste paper; The recycling rate of old newspapers and magazines in Finnish cities is almost 100%; The recycling rate of waste paper in China is only 30%

why is the recycling rate of waste paper low in China? The boss of a paper company once told the author that this company tracked the people who collected waste paper on the door and found that most of them would first send the waste paper to a certain place to mix sand and spray water... In a certain place in the suburbs of Beijing, the business of mixing sand and spray water into waste paper even developed into an underground industry. If a paper mill wants to use such waste paper, it must first dry the collected waste paper, and then shake the sand out of it. Instead, it is better to import directly from abroad

from this situation, we can see that our legal norms and policy support for waste paper recycling are not specific enough, and their main characteristics are not as follows:. Most countries that have done a relatively mature recycling of waste paper have a set of recycling legal systems that are considerate to the interests of all aspects, highly operational and strict in detail quantification. For paper-making enterprises, it is mandatory to use a certain amount of waste paper as production raw materials; For recycling enterprises, it is stipulated that the government must give certain subsidies to promote the full implementation of emission permits in the cement and glass industry to ensure that they can obtain reasonable economic benefits in their normal operation; For consumers, the administrative law enforcement department will conduct spot checks at any time, and impose a fine on those who fail to classify the waste paper and send it to the designated recycling place as required. In comparison, China does not lack attention, publicity and education to the recycling of resources, but it lacks effective measures and systems. Just imagine that some people do it to make some illegal money by mixing sand with waste paper and spraying water. To ensure the normal cleanliness of the metallographic microscope, if there are appropriate policy subsidies, some people will strive to do a good job in seriously recycling and sorting out waste paper

when people talk about environmental protection and resource recycling, they always like to emphasize that there is a gap in the concept between Chinese and foreign nationals, but in fact, the law sets rules, rules cultivate habits, habits become natural, and naturalize ideas. This is a process. The "circular economy", including the utilization of waste paper, can really grow up by reasonably standardizing the specific links of recycling. 8.
