Recently in the new peak cement plant learned that one end of the production line is a steady stream of domestic waste and cinder slag, the other end is cement.
"This is a new dry cement clinker production line invested 160 million yuan last year, the use of more than 1400 high temperature incineration of domestic waste and the production of clinker after harmless treatment, a year consumes 3 million tons of industrial waste, processing 80,000 tons of domestic waste." "Company waste treatment Workshop Director Yang Zhengang pointed to the production line, industrial solid waste accounted for more than 30% of the total production of raw materials."
At this stage, the market price of water slag per ton of 50 yuan to 60 yuan, cement per ton of about 260 yuan. Since last year, with the national environmental protection policy intensified, many environmental protection substandard small cement plants have been shut down, but energy-saving environmental protection enterprises by the State policy support, to achieve a benign development.
For steel, electricity, coal, coking and other resources consumption-oriented industries accounted for more than 70% of the industrial proportion of heavy industry City of Handan, processing industry "wastes" more urgent and necessary. Hanhan the head of the NDRC, the annual production of industrial waste is basically recycled into cement, new wall. Incomplete statistics, Hanhan Coal gangue storage capacity of about 60 million tons, fly ash storage capacity of about 9.1 million tons. Through the comprehensive utilization of waste gas, waste residue and waste heat, the annual use of coal gangue, fly ash, desulphurization gypsum and other solid waste 20 million tons, high (turn, coke) furnace gas 58 billion cubic meters.
