Suberra is made from 100% post industrial recycled cork. Cork is the quintessential rapidly renewable resource. The bark of a cork oak tree grows three to four inches thick after the first twenty years of the tree’s life. This bark can be harvested from the same tree every nine years without harming the tree, which will continue to grow for several hundred years.
Most of the world’s cork is grown in Portugal. Because of the longevity offered by the harvesting of cork from oak trees, the recurring revenue stream is highly beneficial to the people of Portugal. The bark is stripped from the tree and wine corks are the first product pressed out. The rest of the bark is mulched and used for flooring, tack board, and in the case of Suberra, countertops pressed to the same density as oak.
