  • Ground glass solution for cleaner water

    British science has led to a use for waste glass that cannot be recycled that could help clean up polluted waterways by acting as an ion-exchange filter to remove lead, cadmium and other toxic metals. Details are published in a forthcoming issue of the International Journal of Environment and Waste Management. Only a fraction of waste glass bottles and jars can be recycled, partly because much ...
