Reuse world

Former worthless gangue are competing to buy the one side had been abandoned, polluting the environment tailings “valuable commodity”, a time of fly ash of power plants has become a headache, “instant hit.” Through the development of recycling economy, the introduction of foreign advanced technology, Changxing vigorously promote recycling of waste of resources, resource use through a “chain” becomes longer, industrial transformation and upgrading of the increasingly rapid pace. According to preliminary statistics, Changxing County, the comprehensive utilization of industrial waste has reached 99.67%, air quality improved markedly.

Changxing is a coal and quartz mines and other mineral resources are very rich in the county for many years after mining of coal gangue waste reached 600 million tons, while the quartz mining tailings left over after several millions tons, and annual 30 million tons annually.

To this end, Changxing through the development of recycling economy, turning waste into treasure, and promote industrial restructuring and upgrading. Changxing County, will be looking eye on the most advanced emerging environmental protection industry, to vigorously promote the recycling of waste resources. Through unremitting efforts, the world’s top 500 enterprises in Germany Haniel Shanghai “Yitong,” have settled in Changxing. “Yitong” investment 30 million U.S. dollars in Changxing set up a new wall materials company that specializes in using an abandoned quartz mine tailings production of high-grade aerated concrete wall. Alone, a year consumed quartz mine tailings reached nearly 13 million tons, almost ready to eat, Changxing County, an annual increase of quartz mine tailings half.

through the unremitting efforts, a number of circular economy projects have settled in Changxing. A Portuguese overseas Chinese invested 150 million yuan, in the Changxing County, has established a shale fired brick production line project; Taiwan Chemical Board Co., Ltd., Suzhou Taiwan Wing Building Material Co., Ltd. invested 17.5 million U.S. dollars, in the Changxing County, built a quartz mine tailings as raw materials, annual output of 21 million square meters of the calcium silicate board production line; domestic enterprises are a Changxing built a coal waste as raw materials, 80 million bricks per year of new wall materials factory, one year consumes more than 120,000 coal gangue t.

Currently, Changxing County, only the new type of environmentally friendly wall materials up to 30 enterprises. Productivity through technology to take the recycling economy, the county recycling for one year more than 1 million tons of fly ash, coal gangue more than 500,000 tons of quartz ore tailings more than 300,000 tons.

It is understood that, in addition to the use of tailings, gangue waste to make new wall materials, Changxing County, have also introduced many other new environment-friendly enterprises, such as an abandoned power plant fly ash with cement to do with the abandoned power plant Gypsum plaster board to do, using slag concrete admixture to do so. LAU Kwok Fu Changxing county party secretary, said: “the spirit of the scientific outlook on development to guide economic and social development, we must abandon the practice expense of the environment, out of a path of sustainable development.”

飞入对长兴发展循环经济，促进转型升级的高需求灰

前毫无价值的煤矸石竞相购买一方已放弃，尾矿污染环境“有价值的商品”，一个飞行电厂粉煤灰的时间已成为一个头痛，“抢手货”。通过发展循环经济，引进国外先进技术的引进，大力推进长兴通过“链”越拉越长，产业转型和升级的步伐越来越快的资源回收，资源利用。据初步统计，长兴县，工业废物综合利用率达到99.67％，空气质量明显改善。

长兴是一个煤炭和石英矿等矿产资源十分丰富，全县多年后的废弃物煤矸石开采达600万吨，而石英矿尾矿离开数百万吨以上，年每年3000万吨。

为此，长兴通过发展循环经济，把废为宝，促进产业结构调整和升级。长兴县，将会寻求在最先进的新兴环保产业的眼睛，大力促进垃圾资源回收利用。经过不懈努力，世界500强企业德国哈尼尔上海“伊通”落户长兴。 “伊通”投资3000万美元的长兴成立一个新型墙体材料公司，利用废弃尾矿石英专业生产高档加气混凝土墙。仅消耗石英尾矿去年达到近1300万吨，差不多可以吃，长兴县的石英尾矿每年增加一半。

通过不懈努力，循环经济的一些项目在长兴解决。阿葡华侨投资1.50亿元，在长兴县建立了页岩烧结砖生产线项目;台湾化学板有限公司，苏州台荣建材有限公司投资一千七百五十零点○○○万美元，在长兴县建立了为原料石英矿尾矿，21万硅酸钙板生产线，年产平方米，国内企业是长兴县建立了为原料，8000万，每年砖的新型墙体材料煤矸石工厂，一年多消耗煤矸石12万吨

目前，长兴县，只有环保墙体材料的企业多达30个新的类型。通过技术生产力采取循环经济，一年超过100万吨的粉煤灰县循环，煤矸石50多万吨石英矿尾矿超过30万吨。

据了解，除了使用的尾矿，煤矸石废弃物作新型墙体材料，长兴县，也推出如废弃的电厂粉煤灰与水泥灰其他许多新的环境友好企业与电厂废弃的纸面石膏板做的，用矿渣混凝土外加剂这样做。刘国富长兴县委书记，说：“关于科学发展观的精神指导经济和社会发展，我们必须放弃出了可持续发展的道路环境为代价的做法。”08.10.30
