【防治荒漠化·库布其在行动】“点沙成金”实现治沙生态效益与社会效益双赢

2017-09-21 23:22:00   央广网

央广网鄂尔多斯9月21日消息(记者申明宽)约1.86万平方公里的库布其沙漠,横跨内蒙古鄂尔多斯市杭锦旗、达拉特旗和准格尔旗,是中国第七大、世界第九大沙漠。曾饱受荒漠化侵袭的鄂尔多斯市如今靠发展生态工业、绿色农业等产业化治沙途径,“点沙成金”实现了生态效益与社会效益的双赢。

 聚沙成砖,生态工业治沙取得绿色低碳发展

著名科学家钱学森提出,要在治理沙漠化的过程中更为积极地“用沙”和“治沙”,甚至将沙漠风积沙作为原材料发展成一系列“沙产业”,将是我们征服沙漠、利用自然的方向。而今,这一展望已变成现实。

2013年5月,鄂尔多斯市杭锦旗党政联席会议上提出“走工业化治沙之路”的构想。同年6月,鄂尔多斯市同圆库布其生态工业治沙有限责任公司成立。

“传统的治沙模式是种树种草,生态治沙,我们是工业治沙,就是吃沙用沙,直接把沙当成原材料加工出建筑材料”,鄂尔多斯市同圆库布其生态工业治沙有限责任公司总经理淖门生在接受媒体采访时说。

据介绍,以沙漠风积沙为主原料、工业园区“三废”、煤矸石为辅助原料在1040℃的高温下烧制出的环保市政砖具有较强的透水、透气、耐压、抗折、耐酸、耐碱性。

“变废为宝使得砖块原料成本远低于同类产品,煤矸石和粉煤灰来自隔壁电厂的废料,帮助其处理还会收取一定的费用。每块砖的成本为0.3元,售价为0.8元,产品销往内蒙古及周边省份。”,公司常务副总经理李光说,“目前公司年产能7500万块,预计实现年均利润总额3750万元。”

据了解,联合国防治荒漠化公约第13次缔约方大会在康巴什国际会展中心成功闭幕,而国际会展中心的场外路面就是用这种环保市政砖铺就的。
