Benefits for Office Building
The substantial building cost due to
reduced waste can be lessened, since
the need to pay hauliers to dispose
of construction and demolition
debris is nullified with a proper waste
management scheme.

Benefits for Office Unit
Recycling of construction and
demolition waste reduces demand
for virgin resources and reduces the
environmental impacts associated with
resource extraction, processing and
transportation.

Building Council:
Sort Waste for Reuse and Recycling
Construction and demolition waste were sorted for reuse or
recycling. Bricks, lighting boxes and conduit were potentially
reused in the new office. Other waste e.g. paper, metals, wood
and plastic were collected for recycling.
In addition, 31.8% (by weight) of all building materials were
recycled, and more than 68% of construction waste was sorted
and diverted from landfills.
% of construction waste being reused/recycled:
(Total Weight of Construction Waste being Reused/Total Weight
of Construction Waste) X 100%.
= (1777.22 kg/5589.62 kg) X 100%
= 31.8%

Construction Waste Reduction
Overview
As waste generation by the construction industry has always been a
problem of treatment and management, strategies on waste reduction
should be well planned. During planning stage, a
which includes sorting recycling, and disposal of demolition &
construction waste should be prepared to identify waste types and waste
reduction targets.

At least 30% of construction/demolition waste is recycled.
