Abstract
Sustainable management of construction and demolition waste is very important on islands where resources are limited and transportation is not feasible. A case study was conducted for the first time to estimate the generation rate, composition of construction and demolition waste and the potential savings if construction and demolition waste could be effectively recycled in the northern part of Cyprus. The records on construction permits and the responses of the contractors obtained via a survey were used. The construction waste generation varied in different regions with the maximum amount of 21 × 106 kg in Famagusta, while the construction and demolition waste index was found to be the largest at 0.74 ton/capita/year in Iskele. Concrete (33%) and brick (31%) formed the two largest weight fraction of construction and demolition waste composition. Steel was recycled by 73% of the contractors while reuse/recovery activities varied up to 57% for gravel. Environmental benefit and the legal enforcement were the first two important factors motivating the contractors to source separate and recycle construction and demolition waste. Considering a 90% recycling scenario for general steel, 91.6 × 106 MJ energy and 8.29 × 106 kg CO2 emission could be saved. With the same scenario for aggregates, relatively smaller, 0.63 × 106 MJ energy and 0.08 × 106 CO2 emission were to be saved. An effective recycling system for construction and demolition waste can save considerable amounts of energy and resources while reducing environmental pollution.
期刊介绍：
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
