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).
