Luonnonkorkeista

Luonnonkorkeista is a Finnish term that translates to "natural cork" or "raw cork." It refers to cork material harvested directly from the bark of the cork oak tree (Quercus suber) in its natural, unprocessed state. This raw material is the foundation for all subsequent cork products. The harvesting process, known as stripping, is carefully managed to ensure the sustainability of the cork oak forests, primarily found in Mediterranean regions like Portugal, Spain, and North Africa.

The process involves skilled workers who meticulously peel the outer bark of the trees without harming the living tree itself. This bark, composed of dead cells, regenerates over time, allowing for repeated harvesting every 9 to 12 years. The harvested raw cork is then sorted and processed. Initial processing often involves boiling or steaming to soften the material, making it more pliable and easier to work with, while also cleaning it.

Luonnonkorkeista can be used in various forms. It might be cut into sheets, granulated for use as filler or insulation, or further processed into specific shapes for applications like wine stoppers, flooring, insulation boards, fashion accessories, and decorative items. The inherent properties of natural cork, such as its lightness, elasticity, impermeability to liquids, and insulating capabilities, make it a versatile and sustainable material. Its ecological benefits are significant, as cork oak forests play a crucial role in biodiversity and carbon sequestration.
