Singapore is looking into using byproducts of steel making to help pave roads as part of the city-state's effort to cut the waste it leaves behind, the environment minister said.
Officials are testing ladle furnace slag - waste resulting from steel processing - for possible use as road asphalt, Environment Minister Lim Swee Say said.
Last year, Singapore used incinerator ash to build roads in another recycling experiment. Lim said the National Environment Agency is trying to get local industry to set up a plant for processing incinerator ash.
"We need to continue to take full advantage of technology and come up with new and useful ideas to broaden the scope of recycling , so that more waste streams can be covered," Lim said.
The eventual aim is to create a ""zero landfill, zero waste" city-state, Lim said. Dow Jones
