The reporter learned from the Shandong Provincial Department of Environment and Resources on February 23 that in 2005, 421 industrial resource comprehensive utilization enterprises in the province had used 34.654 million tons of industrial solid wastes, including 8.604 million tons of fly ash and 16.196 million tons of coal gangue. There are 3,922,200 tons of slag, 1.5254 million tons of coal slime, 4.679 billion cubic meters of coke oven gas and blast furnace gas.
Shandong Pentium Enterprise Co., Ltd. uses waste polyester filaments after liquefaction to produce paint, and consumes more than 300 tons of used polyester waste filaments each month. Zoucheng Tianzhuang and other dozens of gelatin factories use the production of leather garments, leather shoes, and leather scraps to produce industrial gelatin, which consumes more than 100 tons of waste.
Xinwen Mining Group uses coal gangue as a raw material to generate electricity, produce cement, and make bricks. Currently, it has achieved a comprehensive utilization rate of 105% of coal gangue, which not only can completely eliminate the coal gangue produced in the year, but also can further digest the inventory.
According to reports, Shandong Province has now identified 623 provincial-level comprehensive utilization companies, which can use more than 34 million tons of industrial solid waste annually, of which only coal gangue can digest 16.196 million tons per year. There are more than 770 coal gangue mountains in Shandong Province, and the comprehensive utilization ratio of coal gangue is over 73%. Comprehensive utilization of power plants such as coal gangue and slime power generation not only reduces pollution but also generates considerable economic benefits. At present, the province's 61 resource utilization power plants have 175 generating sets, with an installed capacity of 2.92 million kilowatts and annual power generation of 8.95 billion kwh.
