Oak trees are native to southern Mediterranean countries like France & Italy and North African countries like Tunisia & Algeria. They can produce bark throughout their lifetime. However, once the trees are fully grown, the bark is harvested, and a mark is made on the tree. This mark signifies that the tree has already been stripped of its bark, eventually allowing it to recover its layer of bark. Scientific studies have shown that oak trees stripped of their bark can live up to 150 times longer.

As you already know, the oak trees are not cut down to extract the bark. This makes cork an nature-friendly and sustainable material.

As Sustainable As They Come: Since cork is produced from the bark of the oak tree, it does not require them to be completely cut down. It makes cork very sustainable and nature-friendly. Furthermore, cork is harvested after an extended period, between 9 to 25 years, and thus, the procedure does not harm the population of oak trees. In addition, the material is reusable and used in flooring and insulating homes.
