Cork-oak forests work just like carbon sinks.
A s well as its capacity to produce oxygen, feature shared by all vegetal species, the cork-oak has a special and unique cell structure that makes it capable of catching CO2, mainly responsible for global warming. The cork-oak is the only specie that can be debarked on a 9-year regular basis, necessary process for the exploitation of cork. A stripped cork-oak will capture 3 to 5 times more carbon than an intact one as the bark growing process increases considerably the photosynthesis. Thus, every time a consumer choses a wine closed with a natural cork stopper, he is directly contributing to the environment protection.
The choice of raw material
It is a natural cycle.
C ork extraction is one of the most environmentally friendly exploitation processes. Unlike a vast number of common preconceptions, no tree-cutting is needed during cork extraction.
Cork oak stands exploitation contributes to:
- Maintain the “Mediterranean lung” .
- Preserve one of the natural environments exploited which contains the greatest diversity and inestimable reserve of endangered animal species.
- Fight efficiently against desertification, pauperization of local populations and definitive loss of an ancestral know-how.
Bourrassé Group based its energetic policy on the sustainable development.Steam is used at every stage of the production. Two generators produce this steam by using cork dust from the productions.
All the sewage from the production, boiling water, rinse water, is treated on-the-spot in a dedicated processing station certified by the Portuguese Department of the Environment and regularly inspected. The efficiency of this sewage processing station enables to give clean water back to nature.
