What is cork?

Cork is the bark of the cork oak. It is a 100% natural plant tissue consisting of a hive of microscopic cells containing a gas identical to air and coated primarily with suberin and lignin. It has a range of applications associated with its attributes that no technology has yet managed to emulate, match or exceed.

Transformation process

The life cycle of cork as a raw material begins with extraction of the cork oak bark, which is called harvesting. Cork enters the manufacturing process after it is extracted, to produce the myriad of products that we can find: stoppers, construction and design materials, among many others.

Cork stoppers are a natural, recyclable and reusable product. To take advantage of and preserve this valuable resource, a growing number of countries have taken measures to implement recycling initiatives, in order to raise awareness of the importance of this material among local populations.

For example, corkboards, place mats, coasters, flooring, coverings, components for the motor vehicle industry, and insulation material, among others.
