FT: Recycled glass turned into tiles

The Ceramic Technology Group at the university's School of Engineering and Advanced Technology will use microwave-assisted firing to heat the glass particles to about 750Degrees C - a relatively low heat for glass-firing, which will have the additional environmental benefit of cutting fuel emissions as well as reducing costs. When the particles have fused, they can be formed into tiles, which could be produced in a variety of colours.
The same group is trying to find a use for the sludge that is one of the by-products of the water purification industry. They believe the sludge could be used as a raw material in bricks and ceramics.
