Shandong Quanlin Group is a large group enterprise with straw pulp and paper as its core, with an annual production capacity of 400000 tons of refined pulp, 700000 tons of machine made paper, 400000 tons of organic fertilizer, and 2.4 billion food and medical packaging boxes. The company has passed the international quality, environment, occupational health and safety three in one management system certification and the national AAAA level standardized good behavior enterprise certification. It has established a national level enterprise technology center and is a national innovative enterprise and the first batch of national circular economy pilot enterprises. At present, the company mainly produces natural cultural paper, natural household paper, natural packaging paper, natural food and medical packaging boxes, and green organic fertilizers as its leading products.
In recent years, Quanlin Paper Industry has applied for a total of 173 patents (132 authorized patents and 106 authorized invention patents) in the development of straw clean pulping and papermaking circular economy. The patented technology covers all fields including straw preparation, pulping, papermaking, environmental protection, fertilizer manufacturing, and industrial chain related equipment design and manufacturing. Integrated with some patents, three international leading technological achievements have been formed, namely "New Technology for Clean Straw Pulping", "Environmentally Friendly Straw Natural Color Pulp Product Technology", and "Refining Organic Fertilizer Technology for Straw Pulping Waste Liquid". Among them, the technology of clean straw pulping and its waste liquid resource utilization has won the first prize of the 2009 Technology Invention Award from the China Light Industry Federation, and has been evaluated by experts of the second prize of the National Science and Technology Ministry's Technology Invention Award.
Supported by a series of proprietary technologies, Quanlin Paper Industry has developed a circular economy development model based on the deep utilization of crop straw, known as the "Quanlin Model": using ammonium sulfite clean pulping technology to produce high-quality natural pulp from crop straw, the ammonium sulfite produced by ammonium desulfurization in power plants is directly reused for cooking, and natural pulp is used to replace some broad-leaved wood pulp to produce high-end natural cultural paper and natural household paper Natural color food packaging paper, natural color food packaging boxes and other products, waste liquid from the pulping process is recycled to produce organic fertilizer. After comprehensive treatment of water in the middle stage of pulping and papermaking, some are reused for production, while others are discharged. Organic fertilizer is reused for agricultural production. The horizontal coupling and vertical connection of various industrial chains form a virtuous cycle of resources, products, and renewable resources. The characteristics of the "Spring Forest Model" are clean production, circular utilization, complete technical system, distinctive product characteristics, strong market competitiveness, obvious economic, ecological, and environmental benefits, and broad development prospects.
Unlimited innovation, exploring the future. Today, Quanlin Paper Industry is actively utilizing its market, brand, and management advantages, focusing on environmental protection and governance, relying on technological and strategic innovation, comprehensively utilizing industrial resources, fully implementing the strategic plan of "circular economy and low-carbon development", fulfilling the corporate mission of "green Quanlin ecological paper industry innovation and development benefiting society", and creating a beautiful environment, harmonious production and nature Quanlin ecological industrial park
