SINGAPORE: In the near future, building materials, such as floor and wall tiles, insulation materials and concrete, could be fashioned from bits of waste glass at only a fraction of its current recycling cost.
Last year, more than 57,000 tonnes of waste glass was generated in Singapore.
After a year of research, a team from the Centre of Innovation in Environmental and Water Technology at the Ngee Ann Polytechnic (NP), believes it has come up with a greener alternative by converting waste glass into building materials by crushing and blending the glass with an eco-friendly binding agent.
Currently, waste glass is either dumped at the Pulau Semakau landfill or sold to recycling companies overseas where the glass is re-melted at temperatures of 1,600°C.
Not only is this method expensive, it also consumes a lot of energy and generates massive amounts of carbon dioxide and other toxic gases.
