Cork is a truly renewable resource. Unlike solid wood, composite wood products, paper and other “renewable resources”; no trees are cut down to make cork products. In fact, Cork Oak trees in Portugal and most other producing countries are protected by law.

 

The product that we know as cork consists of the bark of the Cork Oak tree. The bark is stripped from about 1/3 of the tree every 9 to 12 years. This process enhances the life span of the tree. Without being periodically harvested, the life span of a Cork Oak would be considerably shorter than the 150 to 200 plus years seen in cultivated trees. The manufacturing process of cork products also produces a near zero waste stream and results in no toxic emissions.
