3R Gap Analysis and Findings
From the amount disposed, 57% was generated
from residential premises, food centers and
markets. Commercial and industrial premises
accounted for the remaining 43%. The per capita
waste generation in 2006 was 0.89 kg/day.
The efforts of the Singapore Government in
promoting recycling as a means of reducing the
load on incinerators and landfills has proven to
be fruitful. This has resulted in a decreasing rate
of waste reaching the incinerators and landfills
in recent years. The figure below presents
information on recycling rates and waste
disposal in Singapore.

In Singapore, 90 % of the waste is incinerated at
the four plants (Ulu Pandan, Tuas, Senoko and
Tuas South) and the remaining 10% of noncombustible
waste are disposed at the Semakau
Offshore Sanitary Landfill. Incinerating waste
has reduced the volume of waste to 90% and
has satisfied nearly 3% of electricity demand
for Singapore through energy recovery.
About 980 million kWh of electricity is
generated/year and 22,800 tons/year of scrap
metal is recovered for recycling from the
incineration facilities. About 600 tons/day of
non-incinerable waste and 1,400 tons/day of
incineration ash is disposed of at Semakau
landfill. The waste treatment facilities found in
Singapore are four waste-to-energy plants, one
landfill, one biological treatment facility and 10
recycling units for paper and plastic.

Findings
The public waste collection scheme is built on
a collective platform where pre-qualified
waste management companies compete to
provide refuse collection services for the
designated domestic and trade premises in the
island’s nine geographical sectors. They also
need to provide door-to-door collection
services for recyclable materials from the
households in their sectors under the National
Recycling Program. Presently, four public
waste collectors are providing the collection
services in the nine sectors.
The National Recycling Program for
households was introduced by the National
Environment Agency (NEA) in 2001 to provide
a convenient means for the public and private
housing estates to recycle their waste.
