Researchers in Italy have developed ceramic tiles that use difficult to recycle waste glass in place of feldspar minerals. This creates a product that can be fired at lower temperatures while providing an environmentally friendly way to dispose of the glass.
A high performance concrete designed to reduce the impact of bomb blasts is being investigated by engineers at the University of Liverpool, UK. The material is reinforced with steel fibres and has already been employed in slender footbridges and government buildings in Australia.
A brick containing 97% recycled glass has improved energy efficiency compared to clay bricks, claims UK firm Geofusion, based in Worcester. The geobrick is produced from a combination of container glass and cathode ray tube panel glass.
While glass recycling rates have risen over the last decade in the UK, the amount of recycled content in glass containers has fallen, according to a report released by WRAP. This is due to a shortage of high-quality cullet caused by the co-mingling of recovered glass during collection and processing by UK municipal councils.
Canadian company Carbon Sense Solutions Inc claims its technique to accelerate concrete curing will not only reduce greenhouse gas emissions, but will replace conventional energy-intensive steam and heat accelerated curing techniques.
Designers at the Saazs Institute, based in Paris, France, claim to have developed the first light-emitting glass, which can last for 20 years. The material could be used to create luxury lighting products for homes, hotels and retail outlets.
Researchers at the University of the West of England, in Bristol, UK, have developed an online dynamic photometric stereo system for 3D inspection of fast moving, difficult to analyse surfaces, such as glazed or textured ceramic tiles.
