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
　　一項供收集的時間序列有關的，數(shù)據(jù)總結廢物產(chǎn)生的調查方法，它描述的是蘇格蘭的垃圾填埋和回收，數(shù)量估計是從一個1999年的試驗性報道調查得出的。數(shù)據(jù)報告關于的是建筑及拆卸材料的，還有工業(yè)廢料和副產(chǎn)品和瀝青脫落和分解;附加的還有有關此方面報道。提到估計10，200kt的廢棄物和一些5200kt的被填埋和5500kt再利用（額外500kt的是現(xiàn)有庫存的工業(yè)廢消耗和副產(chǎn)品的損耗） 。一些有關回公用事業(yè)用的骨料回收數(shù)據(jù)的報道，是關于將來對骨料再生的回收為主題的。

　　1.導言
　　政府現(xiàn)正致力于可持續(xù)發(fā)展。蘇格蘭行政院（ 1994）告知骨料循環(huán)再造正在在減少主要骨料的需求。通過增加使用循環(huán)再造碎石料，通過增加使用循環(huán)再造碎石，新的采石場的需求應減少，與相應的好處而言，就是保留農(nóng)村未受污染的的這一好處。新的建議往往產(chǎn)生強烈的地方反對，這可以避免的。
　　此外，建筑及拆卸廢物占約50 ％的受管制廢物在蘇格蘭和，因此，采取重大的堆填區(qū)空間?，F(xiàn)場技術，以重用這些廢物可以減少進口材料。一增加，在回收和再利用此類廢物的，可以在適當時候，降低要求堆填區(qū)。在此背景下，蘇格蘭行政院開發(fā)署（ sedd ）委托的研究提供資料的規(guī)模和目的，其中循環(huán)再造碎石料目前正付諸表決。
　　該項目組成的兩個主要目標，即：
