Tire-Garden5One appropriate use for old tires is in Earthship homes. Earthships are passive solar homes that are built largely with used tires. Another common reuse application for old tires is garden bed construction, in which florae are planted in soil contained by old tires. A question we frequently receive during our free CCAT tours is if the tires used in these projects pose health risks through offgassing or chemical leaching. While the answer we offer is not the most exciting, it is a common saying that you will hear in response to many appropriate technology questions. That saying is, “it depends”.
