Shandong Quanlin Group: Point "Grass" into Gold and Waste into Fertilizer

Our reporter Qiao Jinliang

In early autumn, in a wetland in Gaotang County, Shandong Province, koi fish swim around in the water, and reeds and other aquatic plants are particularly green. However, no one would have thought that this is an ecological wetland of an enterprise pulp and paper environmental protection treatment system.

This company is called Shandong Quanlin Group. It is a comprehensive straw utilization enterprise and the first batch of national circular economy pilot enterprises. Straw pulp and paper, is an industrial plate of the enterprise. Once upon a time, "a paper mill pollutes a river" is the impression left by the paper industry. At this time, not far from the wetland, the display board of the total discharge clearly shows the water quality index of the drainage outside the enterprise. "Our water quality indicators are not only far ahead of national and local standards, but also better than the environmental protection standards of wood pulp in developed countries such as the European Union and the United States, which can be used for production recycling and agricultural irrigation." Company deputy general manager Ren Lihua told reporters.

In recent years, the production capacity of Quanlin has been expanding day by day, but the consumption of water resources and the total amount of COD emission have shown an obvious downward trend. This is due to its unique industrial model. This industrial model, which includes 241 independent innovation technologies, 190 authorized patents and 5 international leading technologies, covers the whole industrial chain of straw collection and storage, pulping, papermaking and fertilizer production, is called "spring forest model" by the Ministry of environmental protection and the national development and Reform Commission ". This model implements the joint development of raw material and fertilizer for straw, and "eats dry and squeezes all the straw" to maximize the industrial value.

Li Hongfa, chairman of the board of directors of the Quanlin Group, said that the "Quanlin model" has achieved "one grass for two purposes". First, through independent innovation, straw cellulose is used in the production of straw pulp and cultural paper, household paper, food packaging and other high-end products, so as to realize the leap of straw pulp from low-grade product raw materials such as cardboard paper and corrugated paper to high-grade product raw materials. The second is to convert lignin in straw into fulvic acid to produce fulvic acid organic fertilizer.

In the pulping workshop, the reporter saw that the entire process from material preparation to pulping has realized control automation, inspection automation, and this is the world's first vertical continuous straw cooking production line. Jia Minghao, deputy general manager and senior engineer of the company, told reporters that Quanlin is the only enterprise in the world that extracts cellulose and fulvic acid from straw. At present, Quanlin Group can produce 0.4 tons of natural straw pulp and 0.8 tons of fulvic acid organic fertilizer from 1 ton of straw, realizing an output value of more than 5400 yuan.

According to the analysis of experts in the industry, the "spring forest model" has a long industrial chain, and the developable products of cellulose and fulvic acid are very rich, especially fulvic acid has great potential in soil remediation, water purification, breeding and other fields. According to the consumption space of fulvic acid in China, such as large-scale promotion of this model, it can form a strategic emerging industry with annual processing of 0.2 billion tons of straw and huge development space.

Straw Transformation Show Ecological "Color"

The artificial ecological wetland built by Quanlin Group using wastewater oxidation pond will become a wetland park integrating wastewater treatment and leisure and sightseeing.

In Shandong, a major agricultural province and a major paper industry province, when mentioning Quanlin Group, people will first think of two things-natural paper and fulvic acid fertilizer. From focusing on papermaking in the early years, leading the industry in the fields of coated paper and soft wrapping paper, to now focusing on the comprehensive utilization of straw and covering the products of straw natural pulp and fulvic acid derivatives, Quanlin Group has realized the green transformation from traditional paper industry to industrial and agricultural composite circular economy industry with its unique "Quanlin model.

Clean lotus-environmental protection natural color paper leading the world

The green straw natural color series paper products developed independently with natural straw fiber pulp as raw material without chlorine bleaching and whitening not only add new paper products, but also save a lot of wood consumption.

"Quanlin natural household paper adopts advanced technology that does not contain chlorine bleaching and does not produce dioxin. It has low-carbon environmental protection characteristics and food-grade safety performance. It is not only used in traditional categories such as napkins, kitchen paper, toilet paper, toilet paper, etc. In addition, it is also used as cow nipple wipe paper. This soft, water-absorbent and dioxin-free food-grade household paper has built another safety barrier for milk hygiene and safety." In the product exhibition hall, Fang Xiangyu, director of the household paper sales department of Quanlin Group, introduced.

Quanlin's original original color paper benefits from the company's independent research and development of straw clean pulping technology. Yu Yiji, a famous paper expert in China, wrote in 2014 that in developing new production processes and equipment comparable to wood pulp production, "Shandong Quanlin Paper can be regarded as an example in this respect. The straw clean pulping and the waste liquid resource utilization technology system they created have made straw fiber raw material pulping show new vitality".

Not long ago, the state announced cleaner production technologies in 11 key industries, of which 6 are in the field of papermaking, and Quanlin Group accounted for 4. Quanlin uses natural straw fiber pulp as raw material to independently develop green straw natural color series paper products without chlorine bleaching and whitening, which not only adds new paper products to the paper industry, but also saves a lot of wood consumption. Compared with the economy of wood pulping, the "spring forest model" produces 1 ton of pulp with an average of 2.5 tons of straw, which can replace 4 sides of wood, I .e. the value created by 1500 yuan of straw is equivalent to 2400 yuan of wood.

In the 100000-ton cultural paper workshop, the reporter saw a large straw paper machine, which was independently designed by the company. The head of the workshop said that papermaking is a technology-intensive industry. The biggest difference between straw pulp and wood pulp is the speed of dehydration. The dehydration speed of straw pulp is slow, and the dehydration speed of wood pulp is fast. "The world's leading wood pulp papermaking technology belongs to the European Union, but the leading straw pulp papermaking technology belongs to Quanlin."

In the Tianhe packaging workshop of Quanlin Group, all kinds of natural food packaging boxes attracted the attention of reporters. These natural color food packaging boxes can resist hot oil at 120 degrees Celsius, are stronger than foam boxes and are more environmentally friendly than plastic boxes. They have passed the tests of food-grade testing agencies such as FDA, SGS of the European Union and Japan's Ministry of Health and Welfare. They are environmentally friendly, natural and rapidly degradable. They are the best substitutes for plastic products and foam tableware. Orders are in short supply. 90% of the products are sold to dozens of countries and regions such as Europe, America, America, America, Japan and South and Korea.

Returning Industrialization to Fields -- Providing "Raw Materials" for Ecological Agriculture"

The fulvic acid produced by Quanlin Group is widely used in a variety of crops and has become a package solution to straw burning, improving soil fertility, improving the quality and production of agricultural products, and reducing the amount of chemical fertilizers and pesticides.

"Internationally, the production cost of fulvic acid is relatively high, and the spring forest model reduces it to lower than chemical fertilizer." Guo Liangjin, general manager of research and development of Quanlin Jiayou Company, said that in Quanlin, straw lignin is no longer passively treated as a pollutant, but is converted into highly active fulvic acid fertilizer through a series of independent innovation processes.

Fulvic acid is a kind of water-soluble humic acid, which is recognized as plant growth promoter, fertilizer enhancer and soil conditioner. As early as the 1980 s, there were companies that wanted to produce mineral-derived fulvic acid, but only a ton of fulvic acid could be produced due to dozens of tons of coal. The investment was large and the pollution was serious, and large-scale production could not be achieved. Spring forest through the way of straw extraction to solve these problems.

"The cost of extracting fulvic acid from seaweed in the United States is 170000 yuan/ton. The cost of extracting fulvic acid from lignite is 20000 yuan/ton, while the cost of extracting fulvic acid from straw in spring forest is less than 3000 yuan/ton. The original cost of fulvic acid is high and cannot be applied in a large area. The spring forest model has reduced the cost and made fulvic acid fertilizer more widely used in agriculture." Spring Lin Jia has company deputy general manager Yuan Yan told reporters. Nowadays, the fulvic acid produced by Quanlin Group is widely used in a variety of crops as base fertilizer, top dressing, foliar fertilizer, etc., and has been applied to 40 million mu of arable land in my country.

In the corn field of Xizang Village, Liangcun Town, Gaotang County, the reporter saw two acres of experimental fields cooperated by Shandong Academy of Agricultural Sciences and Quanlin Group. The corn seedlings that have been applied with fulvic acid fertilizer in the experimental field are casually pulled out and placed together with the corn seedlings that have not been applied with the fertilizer. The difference is obvious: the former has more root systems, which means that the ability to absorb soil nutrients is stronger and the leaves are wider, indicating better photosynthesis. The former is several millimeters thicker than the latter when measuring the stem with a ruler.

Experts from Shandong Academy of Agricultural Sciences said that if the conventional application of chemical fertilizer is reduced by 20% and 10kg of fulvic acid water soluble fertilizer is applied at the same time, the yield of wheat per mu is similar to that of conventional fertilization. In the view of Li Hongfa, chairman of Quanlin Group, fulvic acid fertilizer is a package solution to straw burning, improving soil fertility, improving the quality and production of agricultural products, and reducing the amount of chemical fertilizers and pesticides.

Market-oriented storage-to solve the problem of straw collection.

Through the straw collection and storage system of "slicing collection and storage, centralized transfer and large-scale utilization", a four-in-one collection and storage mechanism of "village-level collection points and farmers of enterprise and township collection and storage centers" has been established.

An enterprise has to "eat" nearly 2 million tons of straw a year, while 1 mu of wheat straw can collect about 0.25 tons. Then, 2 million tons of straw is the amount of straw that can be collected in 8 million mu of wheat planting area. How can so much straw be collected?

Quanlin Group has established a four-in-one collection and storage mechanism of "village-level collection points and farmers in enterprise township collection and storage centers" through the straw collection and storage system of "slicing, centralized transportation and large-scale utilization": a village-level collection point is set up in each village, which can obtain special collection and storage equipment, loan guarantee, protection price purchase and other support from the enterprise according to the contract, and is responsible for the baling and collection of straw collection in the collection in the township collection and storage center; every 30 village-level collection points set up a township collection and storage center as a decentralized storage place for straw, which is allocated in an orderly manner according to the production plan; the most important thing is pricing. Quanlin Group sets the purchase price of straw at about 600 yuan per ton, which is much higher than the purchase price of other straw utilization channels, but it still has a cost advantage compared with wood pulping, which mobilizes the enthusiasm of the purchasing and storage personnel.

Zhang Hongjiang, a villager of Sunzhuang Village in Gaotang County and Office, is the head of a village-level collection point, covering more than 4000 mu of land in seven or eight surrounding villages. He bought three balers, each of which can follow two or three combine harvesters. The baling and removal of crops can be completed on the same day of harvest, and all the straw in the surrounding 1000 mu of land can be removed from the field in three days.

Huiyu Modern Agriculture Co., Ltd. is a company under Quanlin Group responsible for straw collection and storage system. Song Zhanyong, general manager of the company, calculated an account for the reporter: based on the fact that a baler completes 250 tons of straw baling every year, village-level collection points can make a profit of 140 yuan per ton of straw and a minimum of 35000 yuan per year, excluding subsidies to farmers, short-distance transportation, fuel consumption and other expenses. Take the 5000-ton purchasing and storage center as an example, excluding the expenses of rain cloth, custody, land use, secondary pressurization and long-distance transportation, each ton of straw can make a profit from 70 yuan to 120 yuan, with an annual minimum benefit of more than 350000 yuan.

The research team of the Rural Department of the Research Office of the State Council pointed out that the collection, storage and comprehensive utilization of straw in Quanlin Group can not only increase the income of farmers in the collection and storage points, but also increase the income of at least the following two types of farmers: ordinary farmers who sell straw and employees who collect and store straw. Farmers. At present, the average price for purchasing farmers' straw at village-level purchasing and storage points is 260 yuan per ton. Based on 0.2 tons of wheat straw and 0.25 tons of corn straw per mu, farmers can increase their income by more than 110 yuan per mu by selling straw alone. The hired farmers who collect and store straw mainly obtain labor income and transportation income. It is estimated that the collection and storage of 1 ton of straw can bring 40 yuan of labor income and 30 yuan of transportation income.

 

Li Hongfa: Green development depends on continuous innovation

 

"Li Hongfa led Quanlin to create a new development model of ecological paper industry and led Quanlin to embark on the road of sustainable development." this is the award speech given by the jury when Li Hongfa, chairman and professor-level senior engineer of Quanlin Group, won the title of circular economy leader in Shandong Province. For his outstanding contributions in promoting the construction of ecological civilization and sustainable development, Li Hongfa also won the "He Liang He Li Award" and the National "Outstanding Engineer Award", and was awarded the first "China Ecological Civilization Award" by the Ministry of Environmental Protection ".

Li Hongfa's green practice is inseparable from the transformation and development of Quanlin Group. In the start-up stage of the enterprise from 1976 to 1993, the output of the enterprise-scale mechanism paper was only 15000 tons, the product grade was low, the structure was single, and it was always in trouble. Since 1993, under the leadership of the newly appointed person in charge, Li Hongfa, the enterprise has increased its investment in technological transformation and successively developed new varieties such as electrostatic copy paper and special offset printing writing paper, with output value and profits and taxes increasing year after year.

Quanlin Group has achieved obvious economic benefits under the implementation of scale expansion, but the impact of environmental bottleneck constraints has become more prominent. Faced with the gradual tightening of environmental standards, Quanlin was once faced with a choice between life and death.

Is it another way to develop imported wood pulp and paper, or insist on straw pulping to break a new path? According to the cost accounting at that time, the environmental protection treatment of pulping in Quanlin accounted for 1/5 of the total cost, and the total expenditure was higher than the wages of employees. The black liquor discharged in the process of grass pulping and bleaching is the main source of pollution in the paper industry, and the water consumption of grass pulp paper is much higher than that of wood pulp paper, "straw pulp paper to commercial wood pulp and waste paper pulping" almost became the one-sided opinion of the decision makers involved at that time. But Li Hongfa's decision: unswervingly develop straw clean paper.

Facts have proved that Li Hongfa's choice is correct. At that time, the neighboring paper mill, which was the same size as Quanlin Paper, had the fluke of "wait and see". The environmental protection project was stopped after only half of the construction, resulting in the shutdown of more than 40000 tons of pulp production line. The paper mill has been ordered by the environmental protection department to shut down. There are also other paper mills to expand the scale of wood pulp papermaking, due to the international wood pulp price fluctuations, can not afford the high cost and limit production, production, production, resulting in a huge waste of investment.

Since then, based on solving the resource and environmental problems related to the paper industry, Quanlin has carried out all-round technological innovation in the comprehensive utilization of straw resources with the realization of clean pulping and papermaking as the starting point. Under the leadership of Li Hongfa, Quanlin has developed a series of equipment in 7 major fields related to straw clean pulping and papermaking. The world's first vertical continuous digester with the highest degree of automation and the largest single-line production capacity, high-speed straw pulp paper machine and other equipment, straw baler and automatic picking equipment and other series of equipment independently designed by enterprises, not only provide enterprise technology The application carrier of the entire industry chain has also strongly promoted the development of localization of industrial equipment.

Zhang Houmin, an internationally renowned pulp and paper expert and a professor at North Carolina State University in the United States, once wrote to Li Hongfa, "We used to think that rapid replacement heating technology and liquid replacement technology were not feasible for wheat straw. Your invention proves our view wrong. You have achieved liquid displacement cooking, which is a new technology that has never been heard of in wheat straw pulping. This modern straw pulping technology is unique in the world and is extremely important for a fiber-scarce country like China".

Right now, Li Hongfa is paying more and more attention to the agricultural application of fulvic acid organic fertilizer in the "spring forest model. He believes that if a larger planting area can be covered, it will make a greater contribution to the zero growth of chemical fertilizers and pesticides in China. More importantly, the quality of crops is expected to be improved, and the quality of cultivated land will also be improved in an all-round way. Today, he is promoting the "spring forest model" in straw-rich areas across the country, exporting spring forest technology, equipment and management. At present, straw comprehensive utilization projects in Dehui City, Jilin Province and Jiamusi City, Heilongjiang Province are under construction.

Straw, paper and fertilizer integrated utilization needs to be popularized

Economic Daily, China Economic Net reporter Qiao Jinliang

China has a large population, with the economic and social development, the demand for all kinds of paper is increasing day by day. However, China's forest resources are relatively scarce, and a large amount of wood pulp for papermaking is imported from abroad every year. In recent years, the external dependence of wood pulp has been increasing, which has seriously affected the industrial safety of China's paper industry. Straw is rich in resources, and straw papermaking can effectively solve the original short-term problems. However, due to the low scale of straw pulp production in my country, it cannot be used in the production of high-end paper products. In addition, the black liquor extraction rate of straw pulp is low, which increases environmental pollution and governance. burden.

If we can break through the technical bottleneck of straw clean pulping, it will make full and effective use of the rich straw fiber raw material resources in China. Through technological innovation, the "Quanlin Model" has not only solved the three major technical bottlenecks of fiber raw materials, environmental protection and water resources that restrict the development of papermaking enterprises, but also realized a virtuous circle of resources, products, and renewable resources, with significant environmental, economic and social benefits., Formed a unique industrial competitive advantage.

Quanlin's practice has made reporters realize that innovation is the main driving force for the development of circular economy. Both the reduction of raw materials and the utilization of waste resources depend on the application of new technologies. Circular economy often involves many industries, therefore, the management innovation within the enterprise is also an important condition. Judging from the current situation of the development of circular economy, the relevant departments should improve the innovation system of circular economy, give full play to the role of large enterprises and scientific research institutes, and create a good innovation environment for green development.

At present, the utilization of straw in my country is mainly used as feed, fuel and fertilizer, and the large-scale industrialization is insufficient, resulting in a low degree of straw commercialization, little direct benefit to farmers, and great limitations in promotion. At present, the integrated utilization of straw, paper and fertilizer has mature technology and significant economic and environmental benefits, which is suitable for large-scale promotion. It is suggested that the relevant departments should take the integration of straw, paper and fertilizer as the main operation mode of the industrialization of comprehensive utilization of straw in China, implement overall planning and layout in areas rich in straw, and at the same time, support and guide social capital to invest in the construction of straw, paper and fertilizer integration projects in areas rich in straw resources, so as to promote the rapid and healthy development of the industry.
