Abstract
BackgroundIn 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).MethodsQuestionnaire 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.ResultsAccording to obtained results, about 82,646,051 m3 of C&D waste (average 16,529,210 m3 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.ConclusionIn 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.
Highlights
In recent years the generation rate of construction and demolition waste (C&D) has significantly augmented
C&D materials are generated from the construction industry of Canada is approximately 27% of the total municipal solid waste (MSWs) that discharged into the landfills [12], about 30% of the total materials disposed in the US landfills [14] and about half of the total waste in New Zealand are C&D wastes [15]
C&D waste generation in Tehran Based on the results obtained from MAPSA, the generated C&D waste in Tehran during the past 5 years was about 82,646,051 m3 which only about 26% has been recycled in Rigsazan factory (Table 2)
Summary
In recent years the generation rate of construction and demolition waste (C&D) has significantly augmented. When new structures like residential and nonresidential buildings, public works projects are constructed and/or existing structures are demolished or renovated According to Graham and Smithers opinion, the main sources of construction and demolition waste could be different activities during various projects. Construction wastes are included about 35% of municipal solid wastes in developed countries and 50% in developing countries which are a major amount of MSWs [13]. C&D materials are generated from the construction industry of Canada is approximately 27% of the total municipal solid waste (MSWs) that discharged into the landfills [12], about 30% (based on the volume) of the total materials disposed in the US landfills [14] and about half of the total waste in New Zealand are C&D wastes [15]. 12% of California’s landfill space are occupied by C&D waste [4]
