The business club reported on July 17 that sludge produced by the printing and dyeing industry has caused many companies to feel guilty. Shangyu Stellar Machinery & Equipment Co., Ltd. has developed and produced high-tech equipment for converting waste dyestuff sludge into valuables: the entire equipment is connected to the boiler in the production workshop. After the sludge is put into the equipment's main hopper, the waste heat of the boiler flue is used first. Dry, and then mixed with coal in accordance with a certain percentage, "the mixture has become a boiler fuel, the entire process almost no scrap. A set of equipment can save more than 100 million yuan per year for the company, the economic benefits are considerable." Stellar machinery Ye Peigen, general manager, said that they had ordered four sets of equipment last month.

Shangyu local printing and dyeing enterprises have been using piles, landfills, or incineration methods to deal with the large amount of dyeing sludge generated daily. Enterprises have to pay a large amount of money, but the environmental protection effect is not satisfactory. Luan Xingxing Machinery Equipment Co., Ltd. has always been manufacturing boiler equipment. When we researched the transformation and upgrading of enterprises last year, we discussed and could we develop a "core competitiveness" project? After more than 10 engineers went to universities and scientific research institutions to inspect, they had “closed themselves” for nearly half a year, and they had finally done their work and applied for a patent.

In April this year, the local “Kunlong plush” investment of 3.5 million yuan became the first customer of the new equipment. Kunlong plush produced about 12 tons of dyeing sludge per day. Ni Jianbo, the person in charge of the company, told reporters that in the past, when they used incineration to treat dyeing sludge, the monthly sludge disposal fee was 90,000 yuan. "After launching the new equipment, the sludge disposal fee is not only saved, but also 12 tons of sludge per day can be converted into 2.5 tons of coal, equivalent to an additional 'earnings' of 60,000 yuan per month." Ni Jianbo said, originally considered There is also hesitation to invest 3.5 million yuan in equipment investment. Now that it has been reduced, "Two years will be able to recover the cost. It is a good deal!"
