关于回收利用减少废物，节约资源美国的建筑业每年产生数百万吨废物。用传统方式处理垃圾，意味着用卡车将其运到垃圾填埋场或焚化炉，这对建筑商来说成本很高，最终也会对环境造成巨大的影响。回收建筑垃圾是降低建筑成本、延长垃圾填埋场使用寿命、将一些原材料重新投入生产流程的一种方法。回收利用在节约能源方面也有巨大潜力。用回收材料制造新产品比从零开始制造新产品消耗的能源要少得多。例如，回收一吨铝所节省的能源相当于36桶石油。在全国范围内，大约30%的城市固体垃圾被回收利用，每年节省大约1.5四次方的能源，或全国总能源消耗的1.5%。尽管循环利用已成为绿色建筑的核心原则，但在实践中，即使对有兴趣的建筑商也面临挑战。由于各种原因，一些类型的清洁废料的回收渠道可能很难找到。对于拆除碎片来说，这就更加困难了。 As a result, lots of construction debris is still taken to landfills or incinerators. Types of debris Major categories of construction debris include cardboard and paper, PVC and other plastics, asphalt roofing shingles, gypsum drywall, metal, and wood. Some of it is fairly easy to recycle. There’s a long recycling history for cardboard, metal and some plastics, for example. Other materials are more difficult to recycle because the material has limited value, or because there aren’t many processors capable of handling it. Opportunities vary by state Some states have very active recycling programs for construction debris while others do not. In addition, regulations on the disposal of construction waste vary from state to state. Massachusetts, for example, bans the…
