Abstract
  A survey methodology for the collection of time series data relating to aggregate waste arisings, recycling and landfill in Scotland is described, and the quantities estimated from a pilot survey for 1999 are reported. Data are reported for construction and demolition waste, industrial waste and by-products and bituminous planings and breakout; additional categories are reported within these as appropriate. Of an estimated 10,200 kt of arisings, some 5200 kt were landfilled and 5500 kt recycled (the additional 500 kt are accounted for by the consumption of existing stocks of industrial wastes and by-products). Data for recycled quantities are reported in terms of the utility of the application to which the aggregates are put. Targets for the recycling of aggregates in the future are also given.

  1. Introduction
  The Government is committed to sustainable development. The Scottish Executive (1994) signalled the role and contribution of recycled aggregates in reducing the demand for the production of primary aggregates. By increasing the use of recycled aggregates, the need for new quarries should be reduced,with consequential benefits in terms of retaining the countryside in an unspoiled condition. New quarryproposals often generate strong, local opposition, which could be avoid
摘要
  一项供收集的时间序列有关的,数据总结废物产生的调查方法,它描述的是苏格兰的垃圾填埋和回收,数量估计是从一个1999年的试验性报道调查得出的。数据报告关于的是建筑及拆卸材料的,还有工业废料和副产品和沥青脱落和分解;附加的还有有关此方面报道。提到估计10,200kt的废弃物和一些5200kt的被填埋和5500kt再利用(额外500kt的是现有库存的工业废消耗和副产品的损耗) 。一些有关回公用事业用的骨料回收数据的报道,是关于将来对骨料再生的回收为主题的。

  1.导言
  政府现正致力于可持续发展。苏格兰行政院( 1994)告知骨料循环再造正在在减少主要骨料的需求。通过增加使用循环再造碎石料,通过增加使用循环再造碎石,新的采石场的需求应减少,与相应的好处而言,就是保留农村未受污染的的这一好处。新的建议往往产生强烈的地方反对,这可以避免的。
  此外,建筑及拆卸废物占约50 %的受管制废物在苏格兰和,因此,采取重大的堆填区空间。现场技术,以重用这些废物可以减少进口材料。一增加,在回收和再利用此类废物的,可以在适当时候,降低要求堆填区。在此背景下,苏格兰行政院开发署( sedd )委托的研究提供资料的规模和目的,其中循环再造碎石料目前正付诸表决。
  该项目组成的两个主要目标,即:
