The Land Transport Authority or LTA is embarking trials to build
roads with recycled waste materials.
This is part of its larger effort to ensure long term
sustainability.
LTA is exploring the use of both processed road construction
wastes and industrial waste
Lim Bok Ngam, Deputy Chief Executive of LTA says in the future
all new roads would be made up of 70 per cent recycled materials
:
"So going forward what we intend to do is we want to increase
the amount of recycled materials in new roads. So, in the long term
our aim is to achieve about 70 per cent recycled materials in the
new roads. So, hence the term green comes in, that means
sustainability."
According to Mr Lim, it's hard to determine how much savings can
be reaped from using the recycled materials.
However, he says by using more of residue from the incineration
of wastes there will be less reliance on imported materials.
In the long run, Mr Lim also believes it will benefit Singapore
environmentally :
"The other advantage really is today many of this IBA is being
dumped at Semakau as landfill, but we think that if we can make use
of them to construct roads, the amount that is dumped everyday
could probably be reduced by half. So, I think potentially this can
extend the life of the Semakau landfill area."
First to be put on trial for six months, is part of a road
stretching 200 metres along Tampines Road, between Hougang Avenue 7
and Defu Avenue 2.
