Cork is tan, but also very green

Cork is the bark of the cork oak tree. This tree produces a layer of cork every 9 years, so taking the bark off does not kill the tree. The bark is then used to make wine corks. The process of manufacturing wine corks results in corks and cork waste. 70% of the bark ends up as cork waste. Granulated cork is made from only the waste by-product of industrial cork production. We also buy used wine corks to grind and thereby re-cycle them.
