Natural cork is a renewable material harvested from the bark of the cork oak tree, primarily found in Mediterranean regions. The harvesting process, known as cork stripping, does not harm the tree, allowing it to continue growing and producing cork for many years. This sustainable practice makes cork an environmentally friendly choice for various applications. Cork is widely used in products such as wine stoppers, flooring, and insulation due to its unique properties. It is lightweight, buoyant, and resistant to moisture, making it ideal for sealing bottles and providing thermal insulation. Additionally, cork is biodegradable, further enhancing its appeal as a sustainable material.
