Reuse and Recycling

Reuse and recycling could divert construction waste from waste stream back to the construction cycle. This can be achieved through balancing cut and fill, reusing items such as hoardings, formworks and scaffoldings and recycling materials such as metals, concrete and asphalt. Demolition waste can also be reused and recycled on-site in new construction as bricks and tiles in new fixtures. Besides, on-site crushing of concrete could also enhance use of recycled aggregates in new buildings.

On-Site Sorting

Sorting is important to recover waste for reuse and recycle. To facilitate sorting, a specific area should be allocated for on-site sorting of waste while suitable containers should be provided to temporary store the sorted materials such as metals, concrete, timber, plastics, glass, excavated spoils, bricks and tiles. If small area of the site limits detailed sorting, waste material should at least be separated into inert and non-inert portions.

Orderly Disposal

Prior to disposal, all materials should be sorted and reused on-site or off-site while recyclable materials should be collected for recyclers' reuse. Public fill should then be transported to public fill reception facilities while remaining construction waste should be disposed of at landfill. To avoid fly tipping, contractors should follow Works Bureau's practice under the Trip-Ticket System to ensure that truck drivers dispose of construction waste at proper places.
