Cork is an incredibly unique and naturally sustainable ecological material that has many uses outside wine bottles. The cork comes from the outer bark of cork oaks, so it is a renewable resource that can be harvested without damaging the tree itself. Cork oak forests are carefully monitored by their owners and environmental authorities to protect their health, and they themselves contribute to soil fertility and local biodiversity.
It is a 100% natural raw material, that is 100% reusable and 100% recyclable, extracted from cork oaks without harming the normal development of the species and without damaging the tree. The extracted cork is 100% harnessed. Once processed, into stoppers for example, cork can also re-enter the production process. The cork stoppers can be recycled by shredding. The granules resulting from this process can be used in other products, such as shoes, cladding panels, fishing buoys.
Over 50% of its volume is air, which makes it very light. It weighs just 0.16 grams per cubic centimetre, and it can float.
Impermeable to liquids and gases
It is totally impermeable to liquids and practically impermeable to gases, thanks to the suberin and cerin present in the composition of cork cells. Its resistance to moisture allows it to grow old without deteriorating.
Elastic and compressible
It can be compressed to around half its thickness without losing any flexibility, and it decompresses, recovering its initial shape and volume, as soon as it ceases to be compressed. This flexibility is given by its airtight cells containing a gas mixture similar to air. It is the only solid that when compressed on one side does not increase in volume on the other axis. It is able to adapt to variations in temperature and pressure without suffering variations, due to its elasticity.
Cork is resistant to wear, thanks to its honeycomb structure, which makes it less affected by impact or friction than other hard surfaces.
Cork is recognized as one of the most ecologically friendly materials available. It is completely natural, renewable in nature and easily recycled. Also, the cork oak tree is part of a very delicate ecosystem, thriving only in the Mediterranean basin, where many endangered animal and plant species have their habitat. UsingCork Oak forests for industry helps prevent desertification and deforestation, thus helping protect this biodiversity hotspot (one of the 35 existing on hearth).
Cork is 100% Vegan, there are no animals involved in its production. You could say that cork cells are plant cells since cork grows in the trunk of a tree, it is its bark.
