One of the greenest alternatives there is, cork is a naturally harvested material, mainly originating in the cork Oak forests. Because it is harvested only from the bark of the tree, it is one of the most highly renewable and eco-friendly resources on the planet. In fact, cork harvesting can help against global warming. While growing, it captures carbon dioxide from the atmosphere and each time it is harvested, the tree absorbs more CO2 allowing the bark regeneration process. Thanks to these trees lifespan, which can go up to 300 years, one tree can supply cork for multiple generations. Moreover, the thick bark acts as a protective barrier against fire and heat, bolstering the safeguard of forests and their wildlife.
