A few days ago, in Shanghai, we discovered that waste paper packaging "turned into" plastic wood flooring. After "Environmental Protection Travel", through the processing and processing of professional manufacturers, waste paper packaging can produce a large number of daily necessities and industrial materials such as recycled paper, floors, trash cans, hangers, table tennis rackets, trays, etc. Can produce good economic benefits. The scientific name of paper packaging is "composite paper packaging", which is composed of 75% pulp, 20% plastic and 5% aluminum to form a 6-layer composite structure. One change: high-quality paper 10% of the recycled composite paper packaging is fortunate to participate in environmental protection trips. During this trip, they can participate in a series of wonderful juggling games. High-quality kraft paper is the first trick of composite paper packaging. Kraft paper pays attention to fastness, so it needs to be produced with long-fiber pulp. The imported long-fiber pulp is priced at 5,000 yuan to 6,000 yuan per ton. According to estimates, 80,000 composite paper packages weigh approximately 1 ton and can extract 500 kg of high-grade pulp. As long as 20% -40% of the recycled pulp packed in composite paper is added to the ordinary pulp, it can be made into high-quality kraft paper, and the market price is 4500-5000 yuan. Kraft paper produced from recycled pulp packed with composite paper is 1,000 yuan less per ton compared to kraft paper produced from imported pulp. In an interview with Tetra Pak China, Yang Bin, vice president of corporate communications, delivered a business card with a "look" that was unusual: the color was yellowish, it looked rough, and it felt like a regular paper. A closer look also has a small line: "Adopt 100% Tetra Pak packaging recycled materials". She told reporters that the separated pulp in composite paper packaging can be directly made into recycled paper products such as paper, envelopes, paper bags, books, exercise books, etc. It can also be mixed with other pulp to make board paper, shoe midsole, paper towels, etc. Because the paper in the composite paper packaging is made of high-quality virgin fiber, it is much more cost-effective than ordinary waste paper. According to reports, the price of paper products made of recycled paper pulp from ordinary waste paper is 2500 yuan per ton, and the price of paper products made of recycled paper pulp packed with composite paper is about 5,000 yuan per ton. At present, the business cards of all employees of Tetra Pak China are printed on this kind of recycled paper, and most of the notebooks are made of softer recycled paper. The reporter saw that this company is still experimenting with recycled paper as printing paper. Two changes: aluminum-plastic particles The fiber, aluminum layer and plastic layer of the composite paper package are bonded together by thermal compound. Due to the different expansion and gravity of the three materials, the composite paper package is put into a professional hydraulic pulper for mixing and beating. Without heating and auxiliary chemicals, the fiber, plastic layer and aluminum-plastic layer will be automatically separated and suspended in water separately. After the aluminum-plastics and paper in the composite paper packaging parted ways, they were transformed into aluminum-plastic particles. The price of aluminum-plastic particles on the market is 3,000 yuan per ton. The particles can be used for 30% of the raw materials of aluminum-plastic panels. They are the raw materials for manufacturing flower pots, industrial trays, sewage pipes and other plastic products. According to reports, more advanced separation technologies have emerged abroad, which can separate aluminum-plastic ions into aluminum ingots and paraffin. Aluminum ingots can once again become raw materials for the production of composite paper packaging. The price per ton on the market is about 19,000 yuan, and paraffin can be used as a chemical raw material. Three changes: color music board A set of student desks and chairs, a teacher's platform ... These seemingly ordinary furniture are not ordinary, all made of waste composite paper packaging materials! According to Tian Jianwei, general manager of Shanghai Caile Environmental Products Co., Ltd., more than 4,000 tons of waste composite paper packaging is recycled into the "new home" every year in Shanghai, becoming the raw material for making environmentally friendly furniture. It is reported that these environmental protection products have been settled in some schools and factories, and will also enter the lives of citizens in the future. He remarked to reporters with relish: 20 Tetra Pak bags can be made into a small pen holder; 200 Tetra Pak bags can be made into a small stool; 2000 Tetra Pak bags can be made into a small table ... According to Introduced, they recycled the Tetra Pak packaging that was discarded at random, and then through a series of high-tech processes such as cleaning, fine crushing, heating, and pressing, magically "made" a piece of material. He told the author that in addition to furniture boards, many wooden construction materials can also be replaced with recycled materials, such as floors, handrails, baseboards, etc., not only waterproof, moisture-proof, acid and alkali resistant, the most important thing is to save a lot of wood every year. Now their company sells the best product is an environmentally friendly trash can. On the streets of Shanghai, you can see this kind of yellow and green double-bin trash cans everywhere. The appearance of this kind of trash can is not much different from the ordinary trash can, but the raw material of the barrel comes from aluminum, plastic, such as milk Tetra Pak, cans, food packaging bags, disposable fast food boxes, etc. that are randomly discarded in our daily life. , Paper materials, and then manufactured through a series of high-tech processes such as fine crushing, heating, and pressing. This material not only turns waste into treasure, but is also waterproof, moisture-proof, acid- and alkali-resistant, and washable, and its strength can reach the national standard of medium-density fiberboard. According to the person in charge, according to the conversion of the materials required for the trash can, an environmentally friendly trash bin is equivalent to saving a tree planted for 3 years, which is equivalent to saving 30 kg to 50 kg of iron ore sand, which should be full. " "Environmental protection trash". Because it is completely made of waste materials, there is no worry about the loss of similar stainless steel trash cans. According to reports, this kind of environmental protection garbage bin has just appeared, and it has already set off a boom in Guangdong, Yunnan, Guizhou, Jiangxi, Hunan, Shandong and other provinces and cities. In Guangdong alone, 30,000 environmental protection trash cans have appeared on the streets, and more than half of the street trash cans in Guangzhou have the surname “environmental protectionâ€. At present, there are about 150,000 various types of trash cans on the streets of Shanghai. It is planned that after 2 to 3 years, half of them will become environmentally friendly trash cans. At present, the number of such environmentally friendly trash cans is no less than 500. Four changes: high strength plastic wood In the Oasis Beverly Villa area, a small bridge beside Linshui is made of 80 square meters of new materials, and it is still as new as it is after 3 years of use. This new material is called plastic wood, which is crushed and extruded from waste composite paper packaging. This material has both the water-resistant and anti-corrosion characteristics of plastic and the texture of wood. It can replace wood and is a popular building material in the world. It is widely used as an outdoor building material for floors, fences, chairs or waterfront landscapes. It is estimated that using one ton of plastic wood products can reduce the pollution of 60,000 waste plastic bags, which is equivalent to cutting 1.5 eucalyptus trees less than 30 years old. At the end of its 7 to 10 year service cycle, these plastic wood products can be recycled. The effect of this two-way cycle is unmatched by other materials. Compared with ordinary wood, the price of plastic wood is slightly higher, which is equivalent to the price of high-grade anti-corrosion wood in wood. At present, the price of plastic wood per ton in the market is 6,500 yuan, the production cost is 4,200 yuan, and the economic benefits are also very considerable. The origin of environmental protection and the high price have made some manufacturers all over the country optimistic about the production of plastic wood. According to reports, the plastic-wood products produced by a company in Nanjing are not only used for the leisure chairs in Nanjing Zhongshan Mausoleum Scenic Area and the boardwalk along the Qinhuai River, but also for the Beijing Olympic Park. According to the design plan, they will provide 3,000 tons to 5,000 tons of plastic wood products for the Olympic Park, which will be used to build the original wooden structure buildings such as the plank road, chairs and flower pots in the park.
