In China, Guangdong Jiangmen Ganhua (Group) Co., Ltd., which is the first to implement comprehensive utilization of sugarcane in China, not only made almost all the waste generated from its own use of sugarcane sugar be comprehensively utilized, but also largely digested other regions of the Pearl River Delta and Guangxi, Hainan, and the cane system. The wastes such as sugar cane bagasse and waste molasses have emerged from a new path of developing circular economy.
Affected by equipment, process and other factors, Ganhua has for a long time discharged a large amount of pollutants such as papermaking wastewater, boiler dust, and pollute the surrounding water and atmosphere. In order to achieve full compliance with industrial pollution sources, Ganhua has invested a total of 240 million yuan in pollution control and process renovation since 1998. In order to treat the middle-stage wastewater, 30 million yuan was invested, and a wastewater treatment center with an area of ​​16,000 square meters and a daily treatment capacity of 25,000 tons was constructed. Biochemical plant yeast and alcohol wastewater were also introduced into the center for treatment. The company also invested more than RMB 1.6 million to transform and match the original air floatation white water recovery unit in the papermaking workshop. The treated white water was partially recycled as paper machine spray net water and dilution water.
The concentration of red liquor produced in the production process is high and the pollution is large, and it has always been a key difficulty in the governance of Ganhua Group. Through repeated argumentation, Ganhua Company introduced clean production, a new environmental pollution control strategy, into the red liquid treatment. In 2000, they invested 190 million yuan to build a process using red liquid as raw material, red liquid extraction-concentration evaporation-spray drying-finished products, to prepare lignin salt with good market prospects, so that the utilization of red liquid Up to 95%, it can produce 30,000 tons of lignin sulphonate, 60,000 tons of water agent, and annual net profit of more than 10 million yuan. It not only completely solves the problem of red-liquid pollution, but also becomes a new profit growth of Ganhua Group. point.
At present, Ganhua Company not only uses all its wastes in a comprehensive manner, but also digests waste generated from sugarcane sugar in the surrounding areas including Guangxi, Hainan and Zhanjiang.
