In recent years the generation rate of construction and demolition waste (C&D) has significantly augmented. The aim of this study was to assessed the quality and quantity of construction and demolition waste in Tehran (capital of Iran).
Questionnaire methods were used for estimating the amount of generated C&D wastes national statistical data and typical waste generation data. In order to defining the composition of C&D waste, trucks were randomly selected and their wastes were separated and weighted.
According to obtained results, about 82,646,051 m of C&D waste (average 16,529,210 m per year) were generated during 2011 to 2016 which only about 26% of them has been recycled. Mixing sand and cement, concrete, broken bricks and soil have the highest amount of the composition of C&D waste in Tehran that was 30, 19, 18 and 11%, respectively. Based on the results, about 2,784,158 t of the waste will generate in 2025 and this is approximately 122% higher than wastes generate in 2016. Based on MAPSA's data, 360 teams of personnel cruise and control the illegal disposals, but due to the expansion of Tehran this number of teams is inadequate and can't be effective in controlling the situation.
In general, the overall condition of C&D waste management in Tehran seems undesirable and needs to be updated based on the experience of successful countries in this field.
近年来,建筑与拆除废物(C&D)的产生率显著增加。本研究的目的是评估德黑兰(伊朗首都)建筑与拆除废物的质量和数量。
采用问卷调查法估算C&D废物的产生量,利用国家统计数据和典型废物产生数据。为了确定C&D废物的成分,随机选择卡车,将其废物分离并称重。
根据所得结果,2011年至2016年期间产生了约82,646,051立方米的C&D废物(平均每年16,529,210立方米),其中只有约26%被回收利用。沙子和水泥、混凝土、碎砖和土壤在德黑兰C&D废物成分中占比最高,分别为30%、19%、18%和11%。根据结果,2025年将产生约2,784,158吨废物,这比2016年产生的废物量高出约122%。根据MAPSA的数据,有360个人员团队巡查和控制非法处置行为,但由于德黑兰面积扩大,这个团队数量不足,无法有效控制局面。
总体而言,德黑兰C&D废物管理的整体状况似乎不理想,需要根据该领域成功国家的经验进行更新。
