the Cork

What is cork?
Cork is the bark of the cork oak tree (Quercus suber). Every year a new periderm grows –formed by rings that grow from inside the cork oak tree outwards– over the older ones, thus forming this bark. The main component of cork is suberin.
Where are you from?
The first references date from 3000 BC in China, where it was used in fishing equipment. But its unique properties were also known to the Egyptians, Babylonians, Assyrians, Phoenicians and Persians. During the classic Greek-Latin era, it was frequently used for the construction of several kinds of buoys, hives and the soles of women’s shoes
   Is it ecological?
The cork industry promotes a non-contaminating economic activity that provides a natural, ecological, renewable, recyclable and biodegradable product to the world market: CORK. Cork is a guarantee for the future and survival of the cork oak forests and an example of sustainable economy.
How is it produced?
Cork is extracted by removing the bark of the cork oak tree, where this material is found. Once the bark is extracted, the tree “rests”, and after a few years have passed the bark is once again removed; this is mainly done for two reasons: because the quality of the bark the following year is not the same compared to that removed for the “first” time and secondly, to prevent a possible depletion of the tree’s production.
where is it produced?
Worldwide production of cork is around 340,000 tonnes, of which Portugal produces 61%, Spain 30%, and Italy 6%.

The Spanish cork sector is mainly in three autonomous communities: Andalusia, Extremadura and Catalonia. There are approximately 150 companies employing around 2,000 workers.
