Dumping the waste – reusing ceramics

Ceramic tile manufacturer Johnson Tiles, Stoke on Trent, UK, has found ways to reduce water consumption and waste. Fifteen manufacturers deliver waste to the company where it is used in the production of new items. This saves over 20,000t of waste ceramics from landfill each year.
