Baghouse dust from glass recyclers, granite dust from quarries, and spent abrasives from water pipe cleaning usually end up in a landfill. But Fireclay Tile uses these materials to produce its Debris Series of tiles. They contain more than 62 percent recycled content and come in 112 colors. At about $24 per square foot, the tiles aren’t cheap, but you can use them sparingly, on your backsplash for example, to great effect. www.fireclaytile.com.
