Hainan Jinhai Pulp and paper industry: building a road to sustainable development (I)

according to Hainan reports, entering the plant from gate 3 of Hainan Jinhai Pulp and Paper Industry Co., Ltd. (hereinafter referred to as Jinhai Pulp and paper), the road is surrounded by flowers and grass, green pulp and paper forests, blue and white alkali recovery boilers, and silver autoclaves reflect each other. Koi and goldfish swim in the pond, and you can't feel the noise often seen in traditional industrial plants

this is a modern industrial picture of the forest pulp paper integrated circular economy model being depicted by Jinhai Pulp paper

Forest Pulp paper integration:

Options for protecting the ecological environment

it is understood that in recent five years, the production and consumption of paper and paperboard in China have increased by double digits. As the treatment technology of black liquor produced by traditional straw pulp papermaking has not been completely solved in the world, for the sake of environmental protection, the state adjusted the raw material structure of the paper industry in the eleventh five year plan, requiring that the paper industry be dominated by straw pulp instead of wood pulp, This action intensifies the demand for wood pulp in the paper industry. In 2006, China's wood pulp import volume has risen to 1/4 of the world's import volume

wood pulp papermaking requires deforestation to obtain wood, which is bound to cause the decline of forest coverage

however, Sweden and Finland are among the top European countries in terms of wood pulp exports, and also one of the countries with the highest forest coverage in Europe, with a forest coverage rate of more than 70%. Their experience tells China's paper industry that the implementation of the forest pulp paper integration strategy has formed a win-win situation for forest protection on the basis of the development of pulp and paper industry

we firmly believe that as long as there is a variety of artificial forests, human beings will inevitably cut down one less natural forest, promote the construction of artificial forests, and increase farmers' income at the same time, it can alleviate the tension between wood supply and demand, thus protecting the decreasing natural forests and improving forest coverage. Li Zhenlin, the associate manager of the company, passionately explained the relationship between Forest Pulp paper integration and afforestation

the so-called Forest Pulp paper integration refers to a mode in which forestry and pulp and paper enterprises build fast-growing and high-yield raw material forest bases in various forms, and combine pulping, papermaking, afforestation, forest management, logging and sales to form a virtuous cycle of industrial chain and drive the development of forestry and paper industry. The economic, social and ecological benefits of ecological forest management, environmental pulping and green papermaking will develop simultaneously. Is its goal

at present, Jinhai Pulp and paper has created one million mu of fast-growing and high-yield forests. Jinhai Pulp and paper factory has been put into operation in 2005. The paper mill with an annual output of 1.6 million tons of Jinhai Pulp and paper phase II project with a total investment of 13.6 billion will be put into operation next year. At that time, Hainan's Forest Pulp and paper integrated industrial pattern will basically take shape

environmental protection:

pollution control in the process

traditional papermaking has always been regarded as a major polluter, which is difficult to break through the dilemma of white foam but high price and bad smell of black water

it is understood that the wood in natural air drying state after cutting generally contains 50% moisture, 25% fiber and 25% lignin, but the composition of wood pulp is only fiber, and lignin is the main pollution source wood pulp black liquor. This is the material that all pulp and paper mills cannot avoid. Some pulp and paper mills with backward production technology mostly discharge it into rivers, lakes and seas without treatment, causing environmental pollution

however, beside the sewage treatment plant in Jinhai Pulp and paper mill area, I saw a pond surrounded by flowers, in which nearly 100 Koi and goldfish swam. Koi and goldfish have very strict requirements for water bodies. They cannot survive if the water quality is slightly polluted

the water in the pond is treated and discharged up to the standard, which is much lower than the national first-class discharge standard. Li Zhenlin said proudly to. According to the introduction, the water consumption per ton of pulp in the national standard is 220 tons, while Jinhai Pulp and paper factory only has 18 tons, and the indicators of BOD and SS only account for 3.51% and 5.73% of the national standard

this is entirely due to the ongoing implementation of the forest pulp paper integrated circular economy model, which puts forward a creative concept of pollution control in the process, rather than end treatment

that is, in the production process, save resources, improve resource utilization, and reduce the emission of pollution + 2, rather than end treatment. Li Zhenlin further explained. Jinhai Pulp and paper plant is by far the largest, most advanced and most environmentally friendly single pulping production line in the world. Of the total investment of 10.2 billion yuan, 2.4 billion yuan for environmental protection is mostly invested in the production process rather than end treatment

it is learned that the alkali recovery furnace of Jinhai Pulp and paper plant is the largest and most advanced alkali recovery furnace in the world at present, and it is the most important environmental protection equipment of Jinhai Pulp and paper. The alkali recovery rate reaches 98%, while the general pulp plant has only% alkali recovery rate, which is equivalent to saving about 1million tons of standard coal every year. Communication function: the storage, inquiry and output function of the experimental declaration

therefore, in the process of producing wood pulp, the pulping wastewater (liquid) containing lignin and chemical liquid is recycled by alkali, and the lignin is burned for power generation and heating, providing 80% of the power of the whole plant. At the same time, it realizes the recycling of chemical liquid, saves energy and waste, and effectively reduces the pulping cost

leading:

driving the wheel of the local economy

large industrial projects are the main support for the continued growth of the industrial economy. It has the characteristics of large investment, high output value, long industrial chain, strong driving force for local economic and social development, and large industrial projects are conducive to the rapid increase of economic aggregate

it is reported that in 2007, Jinhai Pulp and paper achieved an industrial output value of 6.4 billion yuan, accounting for about one seventh of the industrial output value of Yangpu Economic Development Zone. After the paper mill with an annual output of 1.6 million tons is put into operation next year, its annual output value will reach about 20billion yuan

at present, the Yangpu printing and packaging Industrial Park, which is attracting investment, is built on the basis of a 1million ton pulp and paper mill and a 1.6 million ton paper mill, which has attracted a large number of printing and packaging enterprises from Hong Kong and Guangdong to visit and negotiate. Hainan newspaper group has settled in the park in advance and will invest 50million yuan to build Yangpu commercial printing project. The preliminary work has begun
