Quercus suber (Cork Oak) bark, Portugal by Sallyofmayflower: Cork production is considered sustainable due to the fact that only the bark is stripped and the tree continues to live and grow. Trees live for about 200 years and are stripped from their trunks every 9 years, starting when the tree is about 25 years old. http://en.wikipedia.org/wiki/Cork_(material) #Cork_Oak
The images in this gallery are from a 2011 trip to Portugal, home to 53% of the world's cork supply. Sponsored by APCOR (the Portuguese Cork Council) and Amorim (the world leader in cork products), I was able to travel across Portugal to document the entire agricultural and industrial facets of the cork sector. These images were published as part of a series of galleries and articles on the design journal Core77. You can read them here .
