2018-8-13 Material waste is becoming a serious environmental problem in many large cities around the world. In the UK, the construction industry generates lots of waste which has a significant impact on the environment (i.e. demand for landfill and the depletion of natural resources) (Ferguson et al, 1995).
Read More2016-1-1 Abstract. Waste materials are a major environmental problem, which is a threat to the environment. It is important to reuse these materials and dispose of them. Waste can be used in the construction industry in two ways: by reusing (reuse components) and recycling (processing waste into raw materials used in the production of building materials).

Material waste however is a greater concern as it is extremely expensive and is made up of non-renewable resources. According to H Lau (2008), large amounts of material wastes are generated from construction sites.

These construction materials require high embodied energy resulting with large CO 2 (Carbon Dioxide) emissions. The embodied energy of steel is about 32 MJ/Kg and for cement is about 7.8 MJ/Kg (Scientific and Industrial Research Organization). The highest CO 2

This still leaves nearly 5 million tonnes sent to landfill, about which little is known.
Read More2014-9-1 The interest of researchers and practitioners on the impact of construction waste on the environment has increasingly grown, emphasizing on waste management and putting forward various measures with potential to minimize the adverse impacts of construction waste. Such efforts include waste reduction, reuse, recycling, and disposal . Waste reduction is a process that avoids, eliminates, or minimizes waste

According to the Building Material Promotion Council, India generates an estimated 150 million tons of C and D waste every year. Some existing initiatives and the significant stakeholders' involvement have created the ...
