Carbon Black is one of the most important components in neoprene. It is extracted from old, scrap tires at Quiksilver. The Carbon Black that Quiksilver now uses in all wetsuits drastically reduces energy consumption and saves 200 g of carbon emissions per wetsuit. Quiksilver recycles waste generated during production and they have received bluesign certification for their fabric factories.
