In recent years, large-scale packaging enterprises across the country have adopted the development of circular economy to accelerate the pace of independent innovation, promote energy conservation and emission reduction, and gradually turn from high-pollution, high-energy-consuming, and high-emission enterprises into healthy, green environmental protection companies.
Guangdong Yulong Paper Group Co., Ltd. is the country's largest manufacturer of packaging paperboard. It plans to produce 7.75 million tons this year and earn more than one billion yuan in exports. The company always adheres to the concept of “no papermaking without environmental protectionâ€. Over the past few years, investment in environmental protection and emission reduction has exceeded 1 billion yuan. For the discharge of sewage COD, the national standard is 100 milligrams per liter, and Xiaolong uses two levels of anaerobic and oxygen-consuming biochemical treatment technology. The COD discharge is less than 80 milligrams per liter, and the water consumption per ton of paper is only 8 tons. As for the emission of sulfur dioxide from flue gas, the national emission standard is 400 mg/m3, while Xiaolong has achieved 200 mg/m3. At the same time, the new CHP power plant newly put into operation last year has adopted the most advanced double Desulfurization technology + circulating fluidized bed technology, sulfur dioxide emissions up to 70 mg / cubic meter. They also built the first domestic waste incinerator in the papermaking industry and basically managed all papermaking waste independently. Moreover, the steam generated by waste incinerators can also be used for papermaking, saving energy and recycling resources.
Jiangsu Daya Science & Technology Group Co., Ltd. focuses on the production of new types of wood-based panels this year, with a production capacity of 1.8 million cubic meters. It is the largest forestry enterprise in Asia. The company made use of waste wood to make medium density fiberboard, which changed the traditional unidirectional wood consumption pattern. In addition, the oil spill from the company's aluminum foil workshop was originally discharged naturally. Now it is investing in the establishment of a recycling device, which saves 80% of its resources.
In recent years, Fujian Qingshan Paper Company has always insisted on creating resource-saving companies. In the past year, recycling of old cement bags was used for pulping, which saved 45,000 cubic meters of wood annually, increased the alkali recovery rate, and reduced the use of 360 tons of externally-purchased alkalis; the post-slag pulp and screening slag was mechanically processed and recycled. 2400 tons of pulp, 3,500 tons of coal. The water technology reform will save 3.8 million tons of water annually, saving 3.75 million kwh. The company has invested nearly 100 million yuan in advanced equipment to save resources.
Ningbo Zhonghua Paper Co., Ltd. formulated an energy-saving plan last year, established an assessment system, and vigorously promoted energy-saving and emission reduction. The company’s output value of standard coal per million yuan dropped by 4.41%, and the value-added coal consumption per million yuan decreased by 16.2%, and the standard coal consumption per ton of paper decreased. 1%. The consumption of tons of pulp decreased by 51 kWh. The Minfeng Group adopted environmental protection hardware measures, and the comprehensive utilization rate of solid wastes reached 80%. The annual recycling water consumption was 7.61 million tons. Since the energy saving and emission reduction work was in place, it received a 200,000 yuan energy saving subsidy from Zhejiang Province.
