Waste paper recycling Qingdao enterprises call for technological upgrading

at 4:30 every morning, 51 year old Zhang Weizhi gets up on time, washes a little, and hurried out with a bottle of cold boiled water and two big snake skin bags. Her job is to pick up the waste that can sell at a high price from the garbage cans along Xuzhou road. Among them, waste paper and plastic bottles are the things she is most willing to pick up. At five o'clock in the afternoon, send the "booty" to a garbage recycling station near hailifeng school. The newspaper is 0.6 yuan per kilogram, and the corrugated paper (carton) is 0.42 yuan per kilogram. You can earn more than a dozen yuan a day

except for a few citizens who accumulate waste paper and sell it to waste recyclers pushing flat cars, part of the daily domestic waste paper consumed in our city is sent to the waste recycling station in this way. "At present, the recycling rate of waste paper in our city is not very clear. The key to the problem is that at present, the technical content of waste paper recycling is very low, and it does not give full play to the maximum utilization value of waste paper." Zhong Shishan, President of the Municipal Environmental Protection Association, said

Qingdao waste paper is sold to other places

"most of the corrugated paper has been purchased by some small paper mills in Weifang and Zibo, and newspapers and books have been purchased by some factories in Yishui, basically no paper mills in Qingdao." The staff of a heat box method for affirmation calibration and protection of thermal insulation steady-state thermal performance iso8990:1994, located near Yanji Road library, told some domestic manufacturers that they could export 5 (6) complaints. At a waste recycling station near Xuzhou Road, I happened to meet a transport truck from a paper mill in Weifang to pull goods. "After the purchase, it is first crushed into pulp and then produced into cardboard boxes. Our company mainly produces ordinary cardboard." The driver, master Huang, told me

the person in charge of the relevant department of the Municipal Environmental Protection Bureau told that at present, most areas, including our city, are not doing well in the recycling and reuse of waste paper. The main reason is that most enterprises lack relevant technologies that can improve the utilization level of waste paper, which makes the recycling and reuse of waste paper at a low level for a long time, and produces cardboard, cartons and toxic napkins and toilet paper that are popular in many areas, The latter even threatens people's health

it was learned from the interview that due to the active adjustment of the industrial structure in our city in recent years, the requirements for environmental protection of enterprises have become higher and higher. Papermaking enterprises that are major polluters have either moved to surrounding counties and cities, or been closed by relevant departments. At present, there are few paper mills in Qingdao, and the digestion capacity of waste paper is very small. As a result, most of the waste paper recycled in our city is purchased by surrounding cities

there is a "money" way to recycle waste paper

as long as people are good at reprocessing waste paper that belongs to 2:1 layer chain structure clay with advanced technology, they can turn waste into treasure and create very considerable economic benefits after sample destruction

"as long as you are good at using, the leftovers of packaging products are also precious." Chen Xirong, member of the expert committee of China Packaging Federation and deputy general manager of Qingdao Hualong Packaging Co., Ltd., told that after Hualong invested in the acquisition of Jiaozhou paper mill in 2002, it invested 4million yuan to carry out relevant technological transformation, adding nano calcium carbonate and Cationic Dispersion glue, which improved the strength and water resistance of corrugated paper. After developing ultra-low gram weight corrugated paper weighing 110 grams (i.e. 110 grams/square meter), And further developed 90 grams of high-tech corrugated paper, which is owned by a small number of domestic enterprises

"at present, most corrugated paper in China still weighs 158 grams. The production cost per ton of our products is 50 yuan lower than the former, but the price is 200 yuan higher. Based on the current annual output of 30000 tons, the economic benefit is 7.5 million yuan, and 5000 tons of waste materials of our enterprise can be digested by ourselves every year." According to Chen Xirong, because ultra-low weight corrugated paper conforms to the international packaging trend of lightweight, moderate packaging and high strength, its products are favored by large export enterprises such as Haier and Hisense, and the market has been in short supply

the potential benefits are immeasurable

"The biggest advantage of waste paper utilization is that it directly reduces the use of raw wood pulp. Waste paper can be directly converted into pulp through relevant processes, and 0.4 tons of waste paper can be used for a ton of paper. One mu of forest can only produce 7 to 8 tons of wood, and one ton of wood can produce nearly 0.7 tons of pulp, which is equivalent to that one mu of forest can only produce 5.25 tons of paper. Using waste paper recycling process to produce 10000 tons of paper can reduce the felling of 762 mu of forest, which is important for reducing wood The significance of cutting down, avoiding land desertification and building a healthy and harmonious living home is not trivial. " The person in charge of a paper-making enterprise in our city calculated this account with

"at present, although the relevant departments pay more and more attention to environmental protection, Qingdao citizens' awareness of recycling and reuse of waste paper is not strong, and there is a considerable gap with the United States, Japan, Finland and other developed countries. Changing the lack of citizens' awareness of environmental protection has positive practical significance for the development of circular economy in Qingdao." According to Dr. Zhang Peiyu, Department of Environmental Sciences, Qingdao University
