Waste glass is crushed into powder and then mixed with a liquid chemical created by the team. The mixture is poured into a mould to form floor and wall tiles, feature walls and insulation material. It is heated up at below 100 deg C for about six hours, in a process called "curing".This causes the chemical to bind the glass particles together to form a more durable material, which looks like concrete and has the texture of marble.
The team from Ngee Ann Polytechnic - Dr Sun Xiaolong, a full-time engineer at the polytechnic's Environmental and Water Technology Centre of Innovation, and two students - took a year to develop this method, funded by the Tote Board to the tune of $70,000.
