Generation of construction wastes has been considered as the major impact to the environment. The Hong Kong Government is pressing waste minimization in construction as an alternative strategy for reducing filling-up of landfills areas by promoting the implementation of Environmental Management System (EMS), Waste Reduction Framework Plan (WRFP) and implementing various environmental regulations.
