Many companies are often guilty of investing large sums of money in order to control pollution. However, a paper mill in Wugang City is not only capable of treating pollution through the use of high-tech methods but also turning waste into treasure.
Recently, the author saw at the paper mill of the Haiming Group in Wugang City that two trucks from other provinces had stopped waiting for goods on both sides of the gate of the plant. Workers were busy turning the yellowish liquid produced by the papermaking waste black liquor. Powder bags shipped. Sun Haiming, general manager of Haiming Group, said: “This kind of fine powder is called sodium lignosulfonate, which is an important additive for cement, coal water slurry and pesticides. In just half a month, our group's paper mill sold this kind of fine powder. More than 1,000 tons."
According to the person in charge of the Pingdingshan Environmental Protection Bureau, the Haiming Group Paper Mill is the only chemical pulp and paper manufacturer in Pingdingshan City. The factory mainly produces stationery paper and cover board, 2000 tons of paper production. Papermaking often requires sewage disposal. The factory is no exception. Since 1998, the plant has been plagued by environmental compliance issues, and its production capacity has been less than 50%, resulting in poor overall efficiency. This year, after the restructuring of Haiming Group, Haiming Group first solved the problem of pollution control in paper mills. In the face of the black liquor processing focus, they invested 5.5 million yuan under the guidance of relevant experts to build a "black liquor resource project." The project can be matched with an annual output of 24,000 tons of wheat straw pulp to dispose of all black liquor and ensure that the corresponding output of papermaking outside the drainage meets the standard discharge. At the same time, they used high-tech means, adding a small amount of additives to the black liquor modified, turned waste into treasure, evaporated to become lignosulfonate. At present, the sales volume of sodium lignin sulfonate is priced at more than 1,000 yuan per ton, and the sale of sodium lignin sulfonate has become a new economic growth point for the plant.
