Using old mirrors, broken windows, and porcelain from sinks, toilets, and tile, ECO solid surfacing binds furnace ash with landfill-bound scraps for a countertop made up of 75 percent recycled content. Durable and nonporous, the marblelike surface is stain-, scratch-, and scorch-resistant, says its maker. ECO—available in 10 colors and two finishes—comes in large slabs that measure 63 inches by 128 inches, as well as in standard tile sizes. Cosentino. 866.579.4326.
