Investigation on the recycling of waste milk boxes by Furen Paper Mill

First, the company profile

Zhejiang Fuyang City Foulon paper mill was founded in 1994, it is located in Fuyang Hope Bridge Industrial Zone Fuchun River, the registered capital of 5 million yuan, the existing total assets of 24 million yuan, of which fixed assets of 10 million yuan, It has 115 employees and 2 paper production lines of 3600 and 1780. It has an annual output of 10,000 tons of medium and high grade special kraft paper, 70% of which are sold in China and 30% are exported to foreign countries.

At the beginning of 2004, the plant implemented a separation and reuse project for discarded milk and beverage boxes. After nearly a year of research and development companies, successfully mastered a more complete decomposition technology (core technology has applied for Chinese patent), the waste milk, drink boxes to achieve the separation of paper and plastic in aluminum on the basis of safety and environmental protection. The separated pulp is the raw material for producing high-grade kraft paper, and the aluminum-plastic composite can be processed into aluminum ingot and industrial paraffin, which realizes a virtuous cycle of waste-recycling resources. The processing equipment and production process adopted by the company are different from the traditional papermaking enterprises. It is unique among many papermaking enterprises in Fuyang City and realizes the recycling of non-degradable waste. The production process of using waste milk and beverage boxes is shown in the following figure.

Figure Waste milk, beverage box decomposition utilization production process

Fulun Paper Mill currently processes about 3,000 tons of waste paper boxes per month, of which about half of waste milk cartons are used. It can consume more than 10,000 tons of waste milk cartons throughout the year. After the scale of production in 2009, it is expected to reach waste milk paper. The box is 20,000 tons/year, which can greatly reduce the landfill volume of solid waste, reduce the pollution of land and water quality, and protect forest and land resources. With the separation of pulp and paper, the quality of the paper is guaranteed. The high-grade kraft paper of various specifications can be produced according to the customer's needs. It is widely used in the packaging industry. It can be made into cartons, envelopes, paper bags and books after deep processing. Products such as exercise books have been well received by customers because of their excellent quality. The products are sold to other provinces in China, and are also exported to Europe, the Middle East and other places.

The wastewater recycling rate of the Fulun paper mill in the production process is up to 80%, and the other 20% of the wastewater is treated by secondary biochemical treatment, and 10% can be recycled. The water consumption per ton of paper is kept at around 10 tons, far below the national sewage discharge standards. Through continuous technological innovation, the plant has achieved good economic and social benefits. It has been awarded the title of Hangzhou Circular Economy Demonstration Enterprise, Fuyang Environmental Protection Education Base and Fuyang Clean Production Advanced Unit. The operating conditions of Fulun Paper Mill from 2006 to 2008 are shown in the table below.

Second, the establishment of waste milk, beverage box recycling system

(1) Establishing a recycling system from the school

It is not easy to cultivate the habit of recycling waste milk cartons. At the beginning, milk cartons, beverage cartons, and scavengers are not needed. Enterprises have repeatedly went to waste collection points, landfills and other places to promote, and even raise prices to encourage everyone to recycle.

In order to establish a recycling system, the plant invested a lot of manpower and financial resources, and even returned the profits of the plant to the construction of the recycling system. Because students drink milk and beverages every day, the factory asks the Fuyang Environmental Protection Bureau, the Communist Youth League Committee and the Education Bureau to give support and establish a recycling system from the school.

At the beginning of 2005, Fuyang Fuchun Second Primary School, with the help of the company, established recycling waste beverages and milk boxes. The person in charge of the factory repeatedly went to the school to explain the benefits of recycling the waste milk box to the teachers and students, and gradually made the students develop recycling habits. After several months of hard work, the results were very obvious. The company recycled about 3,000 kilograms of waste paper boxes, and the school also received more than 2,000 yuan in recycling through empty cardboard boxes. Fuchun No. 2 Primary School set up the Red Collar Love Foundation and donated the first fund to four special students, further stimulating the enthusiasm of teachers and students to recycle the discarded milk cartons.

After the successful recovery of Fuchun No. 2 Primary School, the channel for recycling the waste beverage box of the factory was greatly expanded. In order to let the schools in the city take action, with the help of relevant departments, an activity to recycle the waste milk beverage boxes was carried out vigorously in the schools of Fuyang City. Soon, this action was supported by the Hangzhou Communist Youth League Committee. More than 40 schools in Hangzhou jointly acted to promote the recycling of waste milk and beverage boxes. A steady stream of waste milk and beverage boxes were shipped from various schools to Fulun. Paper mill.

It is understood that in March 2008, Fuyang Environmental Protection Bureau, the Communist Youth League Committee, the Education Bureau, and the Small Working Committee jointly issued a red-collar environmental protection recycling company in each school in the city, and held a listing ceremony at Fuchun Fifth Primary School. The contents of waste recycling are expanded from classified collection of waste paper, waste milk, and beverage boxes to waste plastic bags. At present, 80% of schools in Fuyang City have established a red scarf environmental recycling company.

(2) Establishing a national recycling network

After the school recycling system in Hangzhou gradually took shape, the factory has collected more than 40 discarded milk and beverage cartons in Guangzhou, Fujian, Jiangxi, Henan, Shanghai, Anhui, Shandong and Jiangsu. Establish recycling channels, including college students, laid-off workers, entrepreneurs, and scavengers. At present, Fulun Paper Mill has set up long-term recycling outlets for discarded beverage boxes in Zhejiang, Fujian, Hunan, Anhui, Jiangsu and other provinces. In the future, it will gradually expand the recycling network to the whole country, so that more waste beverage boxes can be recycled.

(3) Establishing incentive measures for recycling

In the acquisition of the waste beverage box, the plant was purchased at a price of 1,900 yuan per ton, and an incentive policy was introduced to launch a series of recycling incentives to encourage the recycling of the waste beverage box industry in society. If the monthly recovery of more than 20 tons is given to 300 yuan per ton, the reward funds will be settled quarterly; the annual recovery will be more than 1,000 tons, and the additional reward will be 100 yuan per ton, and the funds will be settled at the end of the year. In 2007, the company distributed a total of more than 400,000 yuan in incentive funds. This series of measures has stimulated the enthusiasm of the recycling staff, and the company has also received good results. From August 2007 to the present, monthly recycling has increased at a rate of 5%.

Third, the recycling status of discarded milk beverage boxes

The successful implementation of the plant's waste milk beverage box separation project has also opened the door for enterprises. The plant has established a long-term and stable cooperative relationship with the international beverage packaging company, Tetra Pak and Kangmei Packaging Co., Ltd. The monthly supply of scrap is more than 600 tons. The supply contract for the waste packaging box of the Fulun Paper Mill and Mengniu Group is also under negotiation, and the supply of raw materials is fully guaranteed. At the same time, the Furen Paper Mill has also taken a new path for the waste utilization of waste milk and beverage boxes in China. From January to May 2008, Fulun Paper Mill recovered 8,000 tons of waste milk and beverage boxes, produced 4,000 tons of recycled paper, recovered 1,600 tons of aluminum-plastic composites, and realized an output value of 40 million yuan.

In order to prevent secondary pollution caused by waste milk and beverage boxes in comprehensive utilization, the plant has invested more than 5 million yuan to build a secondary biochemical wastewater treatment and reuse project, which will achieve a wastewater recycling rate of 90% and a wastewater discharge of only 10 tons per ton of paper. Tons, COD emissions reached 40mg/L, and basically achieved the goal of comprehensive utilization of waste, comprehensive pollution control, economic cycle development, process clean production, and environmental and economic win-win.

The plant's current production capacity is 30 tons / day, due to the recovery of waste milk, beverage boxes, production capacity is limited, will use independent innovation of aluminum-plastic separation technology to expand production capacity. The company expects to recycle 10,000 tons of waste milk and beverage boxes in 2008 and 20,000 tons in 2009. At present, the plant is ready to launch a new paper machine production line, the production capacity will be 3-4 times that of 2008.

Fourth, enterprise technology innovation

At the end of 2005, at the high-level circular economy forum held in Beijing, the “Packaging Waste Recycling” technical report submitted by Fulun Paper Mill was appreciated by international environmental protection organizations. A milk beverage packaging box weighs 10 grams, including 8 grams of high-quality long-fiber paper and 2 grams of aluminum-plastic material. However, due to the inclusion of adhesives, plastics, aluminum foil and other materials, it is difficult for the general enterprise to separate, thus causing a large amount of packaging materials to be discarded in a white, and the recycling of discarded milk and beverage packaging boxes becomes a difficult problem. According to statistics, the annual output of beverage packaging boxes in China is about 30 billion bales, and it is still growing at a rate of 3% every year. Due to technical limitations, the recovery rate is only about 0.1%, and the rest are landfilled or incinerated. Both treatment methods can cause environmental pollution.

The purchase price of the 1 ton beverage cartons of Fulun Paper Mill is around 1,400 yuan, and 500 kg of high-grade pulp can be recycled. The aluminum-plastic part (20% aluminum, 80% plastic) is processed into plastic particles of 3,000 yuan per ton, which becomes a raw material for the manufacture of flower pots, sewage pipes and other plastic products. In 2007, Fulun Paper Factory recovered 11,820 tons of waste beverage boxes, produced 6,000 tons of high-grade kraft paper, and separated 2000 tons of aluminum-plastic composites, achieving an output value of more than 50 million yuan.

In order to further improve the recycling rate of discarded milk and beverage boxes, the factory cooperated with famous universities to tackle the problem. At the beginning of 2007, the Fulun Paper Mill participated in the research on the “Key Technology and Demonstration of Cleaner Production and Circular Economy – Packaging Waste Resource Utilization Program”, which was officially listed as the National Science and Technology Support Program (2006-2011) by the Ministry of Science and Technology. The project was jointly studied by the Chinese Academy of Environmental Sciences, Tsinghua University, China Packaging Federation, and Fulun Paper Factory. The supporting funds for the project will be 100 million yuan from the China Academy of Environmental Sciences and 300,000 yuan from the China Packaging Federation. The equipment and materials needed for the construction and operation of the supporting demonstration project of the Fulun Paper Factory will be 17.67 million yuan, and 14.4 million will be in place in 2008. Yuan, the state supporting 10 million yuan. In order to achieve the goal of comprehensive utilization of waste milk and beverage boxes, the project has invested a total of 18.45 million yuan (excluding project inputs) since its implementation.

Five, there are problems

(1) Low amount of recycled products and low quality

The factory collects waste milk boxes in 13 to 14 provinces, and the small number of recycling points are directly packaged. The number of the plants is funded by the plant to assist them in packaging. But in fact, the recycled milk box is still less than 1% of the national total milk bottle. The main reason is that the garbage is not classified, the residents are not separated from the dry, wet, kitchen and toilet garbage; the second is that the recycling is difficult, the residents sell the good waste, the cleaning staff takes a part, and the remaining waste contains the waste milk box. However, the sanitation is poor and the added value is low. No one wants to recycle it alone.

(2) Profit margin

Since there is no classification of waste recycling, the cost of classification is increased, and most of the profits of the plant are consumed in the recycling of waste.

(3) Lack of expanded reproduction funds

In 2009, the two projects to be launched by the plant will require a total of 40 million to 50 million yuan. The funds are limited and the funding gap is large. The main reason is:

1. The land approval procedures of the plant are not perfect, and it is difficult to obtain the legal right to use the land. The 11 mu of land currently used by the plant has not been approved by the Ministry of Land and Resources, so there is no land available for mortgage. Calculated according to the mortgage 1 mu land loan of 150,000 yuan, the factory is far from being able to raise the funds for this expansion.

2. The factory guarantee loan requires an additional 2.5% interest, even if there are few units and individuals who are willing to provide guarantee.

3. The capital supply chain of the plant is tight. Most of the liquidity is occupied by raw material purchases. At present, the short-term funds for research and development and new project construction are at least 15 million. The plant is now in the most needed financial support stage. If the funds are in place, the output value of the plant will reach 200 million, which can increase the employment of 300 people. It can process 80,000 tons of discarded milk cartons per year (if it is used for landfill, it will take about 100%). Mu land), producing 40,000 tons of high-grade kraft paper, 8,000 tons of recyclable plastics (plastics accounted for 10% of milk box components), and 4,000 tons of recycled aluminum (aluminum accounts for 5% of milk boxes). If 17 trees are required for the production of 1 ton of paper, 680,000 trees can be reduced. One worker can collect 80,000 people for one ton per month.

(4) Restricted technical transformation projects

In the environmental protection and energy-saving technological transformation projects, the government generally gives priority to large enterprises and limits the number of enterprises declared. For example, a 5 million technology project allows only three large-scale enterprises to declare, and it is difficult for small enterprises to declare, so it is difficult to enjoy preferential policies.

Sixth, countermeasures and suggestions

(1) Improve the laws, regulations and policies for resource recycling, and give preferential treatment to renewable resources utilization enterprises that protect the environment and help them expand production scale. We will improve the land approval procedures, reduce the land approval process, and have certain preferential treatment for the approval of production land for renewable resource utilization enterprises, and encourage them to become bigger and stronger.

(2) Recycling of discarded milk and beverage boxes is a cause of public welfare and is still in its infancy. Hundreds of millions of people in the country are drinking milk and beverages. The recycling of these discarded milk and beverage boxes will be a huge project. It is a major waste and pollution. From this perspective, the Furen Paper Mill has only opened. There is still a lot of work to do in the future. Waste recycling requires the participation of the whole society and needs to be cultivated and supported, especially in terms of policy support. Therefore, the whole society should actively support and participate in this cause, making the recycling of discarded milk and beverage boxes a whole society.

(3) It is necessary to intensify publicity and law enforcement, so that the sustainable concept of energy conservation, environmental protection and effective use of resources is deeply rooted in the hearts of the people, integrating conservation and environmental protection into the school's teaching system, cultivating children's awareness of resource conservation from childhood; creating waste separation and recycling in society. The atmosphere to cultivate the habit of household garbage classification. At present, the government can formulate standards for the distribution of garbage, and distribute the wastes of dry, wet, kitchen and health, that is, a package of kitchen and toilet garbage (wet), and the rest of the package, gradually making the residents develop the habit of sorting garbage. .

(4) Reforming the reporting standards for technological transformation projects. In the declaration of environmental protection and energy-saving technological transformation projects, the fate of the project should be determined by the merits of the project, so that small enterprises can also receive preferential policies. At the same time, multiple companies should be allowed to declare projects and increase the chances of small businesses.
