Sending waste to the landfill is, well, a waste, so the manufacturer uses locally sourced recycled materials to produce the Debris Series of tiles. The products are made using baghouse dust collected from local glass recyclers, granite dust from a quarry, and the spent abrasives from water pipe cleaning. Tiles contain over 62 percent recycled content and come in 112 colors.  Cost: from $23.40 per square foot. Fireclay Tile. 408-275-1182.
