Mazda has achieved recyclability ratios of over 90 percent. Beginning in 2005, Mazda also became the first in the auto industry to fully implement 'bumper-to-bumper recycling' that recycles material from damaged bumpers. Additionally, we have completely eliminated the use of lead, hexavalent chromium, cadmium and mercury, with the exception of exempt parts. Mazda led the motor industry by being the first to adopt a low-VOC sealer that reduces toluene emissions to less than one tenth of conventional sealers. Furthermore, all of Mazda's domestic production sites have attained ISO 14001 certification.
