Construction and Demolition Waste Recycling
In Singapore, about 1.69 million tonnes of construction debris was generated in 2013 and the recycling rate is 99%. Construction and demolition (C&D) waste is usually sorted for the recovery of materials such as wood, metal, paper and plastics, and processed into aggregates for use in construction activities.
Let’s take a closer look at C&D waste recycling:
C&D Waste Recycling in Singapore
There are several recycling companies that collect and sort construction and demolition waste to recover useful materials from the waste such as ferrous metals, plastics, paper and wood. Sorting is done manually and by machines such as magnetic separators. The recovered materials are sent to local recycling companies for further processing. Some of the recovered wood can also be reused for construction activities.
The remaining waste after sorting contain materials such as concrete, bricks, gravel and stones, which are then crushed and screened to produce aggregates of different sizes for reuse in construction activities. These aggregates are also used to make recycled concrete products such as precast concrete blocks, drains and road kerbs.
