6. Conclusions. The construction industry has made considerable progress in its management of waste since the 1990s, when disposal in landfill was common. However, the now-prevalent system of ...

Strategies to reduce waste during construction fall into three broad categories: Designing for Material Optimization. Reduce the amount of materials within the fabric of the building, as well as the waste produced during construction. Design for deconstruction of materials and components at the end of their useful life. Material Selection

The construction and demolition (C&D) waste can be defined as waste material produced in the process of construction, renovation or demolition of structures (Statistics Canada 2000).The C&D is often a significant component, representing 20–30 % and sometimes more than 50 % of the total municipal solid waste.
