Guangjin Group APP has always attached great importance to cleaner production, continuously improved the recycling of waste water, waste gas and waste paper, and realized the green papermaking cycle. In terms of wastewater management and recycling, the APP of Guangjin Group continuously improves the production process, reduces the generation of pollutants and improves the gradient utilization rate of water resources. In the cooking process of wood chips in papermaking, a large amount of dark brown liquid (commonly known as "black liquor") containing alkali lignin will be produced. With its strong strength, APP of Guangjin Group invested heavily in wastewater treatment and established a set of alkali recovery equipment to completely recover "black liquor" and turn it into useful pulping and cooking liquid. At the same time, the heat generated by black liquor combustion is converted into steam to generate electricity, which supplies most of the electricity and heat sources needed by the factory, thus greatly reducing the pulping cost and achieving a win-win goal while protecting the environment from pollution. In the process of pulping and papermaking, a large amount of alkaline and acidic wastewater is often produced. In order to minimize the concentration of wastewater, the pulp and paper mill under APP of Guangjin Group adopts a complete set of advanced pulp and paper technology and equipment to minimize the consumption of water and drugs, and at the same time, the water in the production process is continuously recycled to minimize the wastewater discharge during pulp and paper making, and then the discharge is far superior to the local government standards through the three-stage sewage treatment system. These three-stage treated water can be used not only for watering flowers and plants, but also for raising fish.

In terms of waste gas emission management, Guangjin Group APP strives to make all treated waste gas superior to national environmental protection standards through three major measures. The odor generated in the pulping process is sent to the alkali recovery boiler for combustion through a completely sealed conveying system, and sulfur is effectively recovered at the same time. After chemical treatment, the waste gas from pulp bleaching and preparation of chemicals is converted into air pollution-free gas and then discharged into the atmosphere. Smoke and dust from boilers and lime kilns are discharged after being treated by high-efficiency electrostatic precipitator.

In terms of waste paper recycling, Ningbo Zhonghua Company and Ningbo Asia Pulp Company, which were established by Guangjin Group APP in Zhejiang, China, are large-scale recycling industrial papermaking enterprises with waste paper as raw materials. Among them, Ningbo Zhonghua Company digests and recycles more than 200,000 tons of waste paper every year (the annual processing capacity can reach more than 300,000 tons), and Ningbo Yayi Company digests and recycles more than 400,000 tons of waste paper every year (the annual processing capacity can reach 6.5438+00,000 tons). These two factories use newspaper recycled paper, office recycled paper and magazine recycled paper as the main raw materials to produce high-quality industrial packaging cardboard. Recycling 1 ton of waste paper can produce 0.8 ton of new paper, cut down 17 trees, save 3 cubic meters of landfill space and save more than half of papermaking energy. The recycling process of waste paper is equivalent to cutting down170 thousand trees every year. The recycling of recycled paper saves the increasingly scarce limited resources on the earth, and at the same time improves the economic benefits and social image of enterprises.

While developing, Guangjin Group APP also pays great attention to the reuse of resources. While continuously optimizing the industrial chain, the achievements of Guangjin Group APP in China are obvious to all. The recycling of APP of Guangjin Group is not only beneficial to resource allocation, but also beneficial to future development.
