Speaking of cement plants, the harsh environment of "dust flying all over the sky and noise everywhere" instantly appears in my mind. However , Taiwan Cement has successfully become a green factory, taking the lead in reducing carbon and helping "waste-free cities". How does this enterprise achieve win-win situation?
In front of the office building of Taini Cement, the slogans of "circular economy" and "sustainable development" on the stone pillars are striking, "This is the company's development concept. Economy is important, but sustainability is necessary. Yin Weiming, assistant general manager of Taini Cement, said that in 2017, the kiln tail dust collection and environmental protection upgrading technology, and in 2018, the environmental protection denitrification technology.. Enterprises actively participate in carbon emission reduction and green development with practical actions.
"The fly ash is washed, dechlorinated, dried, mixed and calcined in the kiln, and the system water quality purification treatment and MVR evaporation and crystallization are carried out synchronously to produce salt according to the quality. The whole co-disposal process is circular and closed-loop, with zero emission of pollutants, and finally the reduction, recycling and harmlessness of solid waste fly ash disposal are achieved." Yin Weiming introduced that the company also uses solid waste as an alternative raw material and fuel, which effectively solves the problem of environmental protection while reducing carbon.
The use of cement kilns to co-dispose of fly ash avoids the impact of waste incineration fly ash on the surrounding environment due to landfill, eliminates the cost of land for fly ash to enter the landfill site, the cost of landfill construction, the cost of landfill and the cost of maintenance in the later period, and reduces the secondary environmental pollution. At the same time, it can realize the resource disposal of fly ash in Zhenjiang and its surrounding counties and cities, and play a positive role in the construction of "waste-free city" in Zhenjiang.
Hard work pays off. In December 2021, the enterprise won the title of provincial "green factory", and in 2022, it won the title of national green factory, leading enterprise of green development in Jiangsu Province and three-star green wharf in Jiangsu Province; It has been rated as one of the top 30 industrial enterprises in Jurong City for many years, and has won the honorary titles of "Jinshan Award" for manufacturing industry in Zhenjiang City in 2019 and 2020. The road of green development has become clearer and clearer, and the territory has been formed.
In recent years, Taiwan Mud Cement has made bold explorations in new equipment, new technology and new technology, invested more than 500 million yuan to implement a series of energy-saving and consumption-reducing technological reforms, including the technological transformation of "second-generation kilns" and the co-disposal of cement kilns, and the energy consumption level has reached the provincial benchmark level, which has revitalized the enterprise and reduced the energy consumption relative to that before the technological transformation. The output value has increased by more than 20%. Yang Zhonghong, the head of the enterprise, said that he would comprehensively promote the construction of intelligent chemical plants, achieve energy saving and emission reduction, reduce costs and increase efficiency, and deepen the green development of mines is to keep Jinshan and Yinshan.
