of Jining Conch Cement Co., Ltd.: Coal and electricity account for 70% -80% of the production cost. Enterprises must closely follow national policies to achieve transformation and upgrading and take the road of sustainable development.
In order to maximize the use of resources, enterprises aim at the reuse of solid waste and build solid hazardous waste treatment stations. Through high temperature decomposition, industrial solid hazardous waste can be converted into mineral raw materials for cement production. However, there are many kinds of solid hazardous wastes with complex components, and improper disposal can easily lead to unstable cement quality. In order to solve this problem, enterprises have carried out thousands of experiments to tackle key problems. Laboratory Director
of Jining Conch Cement Co., Ltd. Zhang Tian: We carry out ingredient testing and collocation tests on all hazardous wastes entering the site, constantly adjust the proportion of collocation, form an exclusive formula process table, realize controllable and scientific collocation of ingredients, and greatly improve the comprehensive utilization rate of waste materials.
At present, the enterprise can dispose of 600000 tons of general solid waste and 30000 tons of hazardous waste every year, and reduce the mining of limestone mineral raw materials by more than 500000 tons. Cheng Xiaojian, deputy general manager
of Jining Conch Environmental Protection Technology Co., Ltd., said that the heat energy generated in the combustion process of hazardous waste can reduce the use of raw coal and save 10,000 tons of raw coal annually. At the same time, the local government strongly supports enterprises to make full use of the spare space in the factory area, develop green energy and reduce coal consumption.
Through the development of wind power, garbage power generation, photovoltaic power generation and other five forms of green power, the enterprise generates 207.5 million degrees of electricity annually, saves 55000 tons of standard coal, and builds a green cycle demonstration enterprise to achieve zero external power purchase.
