Cork is a completely natural raw material, originating from the bark of the Cork Oak tree. This extraordinary species plays an essential role in preserving biodiversity and contributes significantly to maintaining ecological balance. Cork oak forests form unique habitats, especially in semi-arid regions, and act as powerful carbon sinks — absorbing large quantities of CO₂ and reinforcing their critical importance for the environment.
Recognizing the unique advantages of cork and the ecological value of cork oak forests, R.CORK proudly operates with a negative ecological footprint, fully aligned with circular-economy principles and renewable natural resources.
