Construction waste represents a large fraction (44%) of the solid waste stream in Hong Kong. Research is being conducted to explore the technologies and practices that reduce the construction waste of commercial and multi-unit residential buildings.

The construction industry in Hong Kong has been relying heavily on traditional building technology. Buildings are usually constructed by the conventional cast in-situ method. Not surprisingly, recent research indicates that cost is the most important factor in selection of construction methods or technologies for building projects. The reduction of Construction and Demolition (C&D) waste is the least important factor in the minds of the contractors. This can be attributed to the availability of relatively inexpensive (currently free) means of waste disposal and the generally low environmental awareness of the construction industry in Hong Kong.

Architects, engineers and buildings managers can minimize the production of waste in commercial, industrial and multi-unit residential buildings through the use of the technologies and practices described in this web site. These technologies are illustrated under these categories:

This  web site offers an assistance to building designers, contractors and other concerned parties regarding the use of low waste building technologies to minimize the building waste.

New technologies are added to the site during our updating process. If you would like to submit a technology description, please contact us.
