Recycling Glass To Clean Groundwater Pollution
“Even though you might send all your used glass containers to the recycling center, only a fraction of them actually get remade into glass. A lot of glass gets shipped to China for processing and ends up being hard filler for construction projects.
Now a scientist in the UK has discovered a simple way to turn ground up glass into tobermorite – a compound that sucks up toxic materials from groundwater. In the future, your old wine bottles could become the key to cleaning up polluted waterways.
Heavy metal-contaminated land and groundwater are global problems, arising from industrial and military activities and also from the natural leaching of heavy metal-bearing minerals,
said Nichola Coleman of the University of Greenwich, the scientist responsible for the new material.
The tobermorite that Coleman has created currently has a rather slow uptake rate for toxic chemicals — it sucks up lead and cadmium — so she and her team are currently working on increasing the rate of absorption.”
