The Land Transport Authority (LTA) is aiming to increase the composition of recycled materials in Singapore's roads to 70 per cent, up from 25 per cent now.

Doing this will not only make Singapore greener, it will also save the authorities millions of dollars, reduce the country's reliance on imported materials, and reduce the speed at which landfills pile up.

To test the sustainability of green roads, a 200m stretch along Tampines Road towards the Kallang-Paya Lebar Expressway will be used.
