Why Choose Us

FAVOURABLE IMPACT ON CORK FOREST:


The cork tree produce cork every 9 years (a renewable raw material).
Avoid soil desertification.
Important in maintaining biodiversity (unique in Europe).
Portuguese forests (cork oaks) trap 5 million tons CO² every year.

 

100% NATURAL INDUSTRIAL PROCESS:


Only uses cork as a raw material.
Without additives ….agglomerate of its own resins (suberin).
90% of the energy consumed is biomass (a by-product of its own industrial processing).
Any wastage from the industrial process is 100% reusable (cork and dust granules).
