LCA confirms a lower environmental impact of the production of ceramic tiles with the use of zircon

The Zircon Industry Association (ZIA) has completed the first Life Cycle Assessment (LCA) of zircon sand production to quantify and compare zircon’s environmental credentials.

The LCA study, entitled ‘Life Cycle Assessment of Zircon Sand Production Applied to Ceramic Tiles’, examines the environmental impacts associated with the production of 1kg of zircon sand. It confirms that zircon has a low environmental impact, mainly associated with upstream mining processes (extraction, separation and drying), much like the mining of other minerals. The study provides a comparison between zircon and alumina in ceramic tiles (porcelain stoneware).

The LCA report was undertaken by Thinkstep AG in collaboration with Centro Ceramico di Bologna.
