Swisstrax, a company out of California, makes an interlocking recycled content floor tile called Ecotrax.  Made with PolyDyne Engineered Rubber Powder, or recycled rubber tires, Ecotrax — according to the company — is durable, strong, and 100% recycled.  Also, to close the loop, Swisstrax takes its products back to be recycled into future products.  It's available in gray colors, various patterns, and two sizes, 13” x 13” x ½” and 15.75” x 15.75” x ¾”.
