Cork is the outer bark of the cork oak tree (Quercus suber L). Over the course of its lifetime, which on average lasts 200 years, it may be stripped around 17 times, acquiring a smoother texture after each harvest. This makes it a 100% natural, sustainable, reusable and recyclable material. Harvesting cork is also beneficial to the environment. Cork oak trees that are stripped of their bark, absorb and store larger amounts of carbon dioxide and also release more oxygen into the atmosphere.
