Green roads ahead


Last month, the Land Transport Authority (LTA) announced a pilot project to build roads with recycled material. The trial will take place over a six-month period at Tampines.

According to this Channel NewsAsia news story, roads in Singapore have used recycled materials for the last 20 years.  This time, more recycled content will be used, i.e. in all four layers as opposed to merely one. In addition, burnt and processed household rubbish will be used in the mix.

If declared successful, LTA will increase its use of recycled content from 25 per cent to 70 per cent, which will take as much as a 50 per cent burden off the Pulau Semakau landfill, extending its use by around 25 years.
