2012-2-1  Most of the CDW comes from the demolition process while minor portions (around 10%–30%) are generated during the construction process (EPA, 2018; Ning, 2017). Reducing, reusing, and recycling of CDW has become an urgent and essential issue, as inappropriate CDW treatment will cause severe environmental issues and land use threats.

A STUDY OF CONSTRUCTION MATERIAL WASTE

2009-3-6  Construction and Demolition waste is a complex waste stream, made up of a wide variety of materials which are in the form of building debris, rubble, earth, concrete, steel, timber, and mixed site clearance materials, arising from various construction activities including land excavation or formation, civil and building construction, site clearance, demolition activities, roadwork, and building renovation. It also includes incidences of wastages in labour and energy used in construction works. However, material waste has been recognized as a major problem in the construction industry that has important implications both for the efficiency of the industry and for the environmental impact of construction projects (Formoso et al, 2002). Most construction wastes which were previously regarded as inert have been found to generate harmful leachates which have negative effects on the environment (Apotheker, 1992, cited in Lingard et al, 2000). As such, it is absolutely imperative for the construction
