Milk composite paper packaging turns waste into treasure

clothes hangers, table tennis rackets, garbage cans, envelopes, desks, garden guardrails, park wooden bridges, shoe soles... Can you think of and store them in dry and ventilated places? Do these items have anything to do with Tetra Pak bricks, Tetra Pak pillows and other composite paper packaging left after we drink milk? In the past, the composite paper packaging of milk and beverages was often thrown away as garbage after we used it, either because we didn't know its waste, or because no one recycled it. However, recently, good news came from Shanghai, Hangzhou, Beijing, Shenzhen and other places. With the support and promotion of Tetra Pak, many operators of a new waste composite paper neglected to check parts in the measurement process. The packaging recycling industry chain is gradually taking shape from south to north. With the help of advanced recycling technology, recycling manufacturers can turn waste into treasure and make a variety of daily necessities, building materials and production materials

since 1998, Shanghai Caile environmental protection products Co., Ltd. has cooperated with Tetra Pak to carry out research and development on the recycling technology of recycled milk and beverage composite paper packaging, and has used waste composite paper packaging to produce recycled products such as garbage cans, outdoor floors, desks and chairs, industrial trays, etc; Since 2002, Shenzhen Green Shield Environmental Protection Technology Co., Ltd. has established the R & D and promotion system of Caile board products, and successively launched peel boxes made of Caile board in Guangzhou, Shenzhen, Shanghai, Beijing and other cities. The main raw material of Caile board is Tetra Pak, which was previously discarded; In April, 2004, Hangzhou Fuyang Fulun paper factory also launched the "hydraulic re pulping and plastic granulation project of composite paper packaging materials". With the strong assistance of Tetra Pak, it uses waste composite paper packaging to produce pulp and plastic particles; In Beijing, investors have negotiated with more than 300 waste collection stations for recycling, and have received strong support from Balizhuang sub district office of Chaoyang District, Beijing. They will carry out the recycling of composite paper packaging in 7 subordinate communities

composite paper packaging, which is widely used in the milk and soft drink industry, is made of paper, plastic, aluminum and other multi-layer materials for aseptic preservation. Tetra Pak brick contains more than 70% of long fiber pulp and 20% of plastic. Previously, it was difficult to separate it from recycled pulp due to technical reasons, so it can only be burned or landfilled as garbage. Now, the new recycling equipment can effectively separate various materials of composite paper packaging, produce pulp and plastic particles from them, and turn waste into treasure

Shanghai Caile environmental protection products Co., Ltd. has found another way to directly crush and extrude waste packaging into "plastic wood". As the composite paper packaging material already contains plastics, fibers and other substances, it is the best use of materials to produce plastic wood. Indoor maximum load equipment, outdoor anti-theft garbage cans and outdoor gardening facilities are all products that give full play to the advantages of "plastic wood". The industrial pallet produced by Shanghai Caile company has also become an alternative to air transportation due to its high strength and light weight. Tetra Pak introduced the practices of Shanghai Caile environmental protection products Co., Ltd. to foreign countries while recommending foreign composite paper packaging recycling technology and experience to Chinese enterprises

recycling starts from the waste packages at the production end

recently, Yili heard good news: the recycling rate of Jinchuan factory, its flagship production base, has reached 100% through the "experiment" button on the control board, which was originally difficult for enterprises to dispose of the waste packages of milk composite paper packaging produced in the production process. This percentage is of unusual significance, which indicates that the recycling of liquid milk composite paper packaging in China has made a good start

a few years ago, the production of waste milk bags has always been a heavy burden for Yili. Yili has to pay a lot of money for the disposal of these so-called "garbage" every year. In order to fundamentally solve this problem, Yili cooperated with Tetra Pak to set up an environmental protection action team in its flagship plant, Jinchuan plant. Jinchuan factory, in conjunction with Tetra Pak China Environmental Technology Department, provided technical support to Rongxin paper factory located in the outer suburbs of Hohhot, and established a composite paper packaging recycling production line with hydraulic re pulping technology as the core in 2003

now, Yili Jinchuan factory and Rongxin paper factory have established a win-win business model. Rongxin paper factory regularly purchases the paper products at the price of hundreds of yuan, and some of the paper products produced by Rongxin are provided to Yili at a preferential price for use as packaging carton materials or building materials for waste room. With the improvement of the production line of Rongxin paper factory, Rongxin has been able to "eat" about 20 tons of waste bags at the production end of Yili Jinchuan factory every month, and the recovery rate of waste bags at Jinchuan factory has reached 100%

yangtinghai, director of Jinchuan factory, said that the production end waste package recycling project of Jinchuan factory is a successful pilot, and we hope that a single spark can start a prairie fire soon. Now, based on the successful experience of Jinchuan plant, the recycling project of Yili Baotou plant has been fully started. Other qualified factories will start similar projects as soon as possible

it is understood that Shanghai Caile company, Shenzhen lvdun company and Hangzhou Fulun paper factory also directly recycle the waste packaging at the production end from nearby Tetra Pak packaging materials factory and dairy enterprises as their important raw material sources

big appetite, not enough to eat

at present, these companies, on the one hand, directly recycle production end waste bags from manufacturers, and on the other hand, with the help of schools, street communities, waste recycling systems, sanitation systems, environmental volunteers and Youth League organizations, recycle waste bags generated in the process of consumption. However, on the whole, their production plants are still "waiting for rice to be cooked"

in April, 2004, Shanghai Caile officially started product production. What is embarrassing is that there is a shortage of raw materials and high production capacity but not enough to eat. Tianjianwei, general manager, said that the factory has set up three production lines. If it operates at full capacity, it can handle 10 tons of waste milk packaging boxes every day. But in fact, only a few hundred kilograms were handled in April. Although there was an increase every month, by the end of last year, only more than 100 tons were handled

finding "food" has become a top priority for Shanghai Caile. At present, Shanghai Caile has begun to recycle the composite paper packaging after consumption in some communities in Xuhui, Jing'an, Putuo and other districts through cooperation with the Environmental Health Institute and the neighborhood committee. Although Shanghai Caile is purchasing waste bags at the price of 800-1000 yuan/ton, the amount of recycling is still limited and can not meet the demand of existing production capacity

Hangzhou Fuyang Fulun paper factory launched the "hydraulic re pulping of composite paper packaging materials and plastic granulation project" last year to produce pulp and plastic particles with waste composite paper packaging. According to manager Yang Jun, its equipment has a monthly processing capacity of 300 tons of waste packaging, but at present it can only collect about 10 tons per month, and the remaining processing capacity can only be used to process conventional waste paper

tianjianwei, general manager of Shanghai Caile, said: we are still "very hungry". If more communities, sanitation departments and relevant government departments cooperate to establish a perfect waste package collection and sorting system, our factory should be able to achieve higher economic and social benefits

in Brazil, which is also a developing country, a garbage recycling system composed of government, non-governmental organizations, enterprise alliances, community public, scavengers and recycling manufacturers makes the recycling rate of waste beverage boxes reach 20%. Relevant experts believe that the urgent task is to form a complete chain in the recycling, classification and comprehensive utilization of packaging waste through market-oriented operation. Now, the comprehensive utilization and development technology of this industrial chain has matured. Enterprises and recycling manufacturers have done a lot of investment and work. What they need is the support of the public and all sectors of society to jointly promote the development of China's circular economy and return these "misplaced resources" to their places
