Waste gas, waste water, and waste residue not only waste a great deal of resources but also destroy the ecological environment. People have collectively called them "the three wastes" with a headache. DONGTAI city insists on scientific development, turning waste into treasure, making the "three wastes" become a resource repository. Host Xu Xiaoyan appears in the scene [Dear viewers, behind me is a new slag grinding production line of Jiangsu Leida Company. It processes blast furnace slag from the metallurgical industry into slag powder, thereby reducing the cost of cement production. This alone can increase the company's revenue by more than 20 million yuan.] According to expert calculations, the newly launched slag grinding production line controls the cost of producing one ton of slag powder for Jiangsu Leida Building Materials Company at around 150 yuan, while the market price is about 200 yuan, thus directly generating a profit of 50 yuan per ton of product. If the enterprise uses it themselves by mixing it into cement, there will be a profit margin of 70 yuan. Simultaneously, China CITIC Heavy Machinery Co., Ltd. Engineer Jiang Chunbo said [The current output, if calculated at 20 hours per day, has an hourly output of 90 tons, so each day is more than 1800 tons, which can generate benefits of 80,000 to 100,000 yuan per day, allowing the vertical mill costs to be recovered in just one year.] Slag and fly ash are used to produce cement, lignite is used for power generation, and coal slag can be used to make porous bricks. These are effective measures taken by Dongtai City’s comprehensive resource utilization enterprises to turn "waste" into "treasure". Similar to Leida Company, Xunda Building Materials Factory in Hougang Town of Dongtai City both conserves land resources and generates considerable benefits through the comprehensive utilization of the "three wastes". At the same time, the factory manager of Xunda Building Materials Factory in Hougang Town, Dongtai City, Miao Zengfa stated [Our Xunda Building Materials Factory produces 12.5 million porous bricks per year. During the production process, we utilize waste residue, saving over 10,000 tons of soil and over 2000 tons of coal, creating a profit of more than 320,000 yuan for the enterprise.] In the recently passed year of 2007, Dongtai's 26 comprehensive resource utilization enterprises utilized a total of over 1.9 million tons of fly ash, over 200,000 tons of coal slag, 150,000 tons of lignite, 120,000 tons of waste cardboard, and 180,000 tons of coal gangue. The building materials and recycled paper products produced from the "three wastes" achieved sales of over 1.6 billion yuan, with profits exceeding hundreds of millions of yuan.
