32、All of these materials have been</p><p>　　produced from existing natural resources and may have intrinsic distinctions that damage the</p><p>　　environment due to their continuous exploitation.

33、In addition, the cost of construction materials is</p><p>　　incrementally increasing. In Turkey, the prices of construction materials have increased over the</p><p>　　last few years (Fig. 1). Th

34、erefore,it is very important to use excavation and demolition wastes</p><p>　　(DW) in construction operations to limit the environmental impact and excessive increase of raw</p><p>　　material pr

35、ices. Recycling ratios for excavation waste (EW) and DW of some countries are in</p><p>　　shown Table 1 (Hendriks and Pietersen 2000). The recycling ratio for Turkey is10%.Every year,</p><p>　　1

36、4 million tons of waste materials are generated in Istanbul. These waste materials consist of 7.6</p><p>　　million tons EW, 1.6 million tons organic materials and 2.7 million tons DW (IMM 2007). The</p>

37、;<p>　　distribution of waste materials, according to listed sources, can be seen in Figs. 2 and 3.</p><p>　　Approximately, 3.7 million tons of municipal wastes are produced in Istanbul every year. How

38、ever,</p><p>　　the recycling rate is approximately equal to only 7%. This rate will increase to 27%, when the</p><p>　　construction of the plant is completed. Medical wastes are another problem,

39、 with over 9,000 tons</p><p>　　dumped every year. Medical wastes are disposed by burning. Distributions of municipal wastes</p><p>　　are given in Fig. 4.</p><p>　　目前，包括沙子、石頭、砂礫、水泥、磚

41、;<p>　　在建筑工程中循環(huán)利用開挖廢料和拆遷廢料是非常重要的。一些國家的開挖廢料和拆遷廢料</p><p>　　的回收利用率見表 1（Hendriks and Pietersen 2000），土耳其的回收利用率是 10%。每年伊斯</p><p>　　坦布爾會(huì)產(chǎn)生 1400 萬噸垃圾，其中包括 7600 萬噸開挖廢料，1600 萬噸有機(jī)材料，2700 萬</p>
