The newspaper La Razón has published an article highlighting a little-known application of Spanish olive stones: their capacity, once converted into biochar, to help remove CO₂ from the atmosphere for centuries.
This is precisely what we do at Carboliva. As it grows, the olive tree captures CO₂ from the air, storing it within its wood and fruit. If the stone is burned as fuel, that carbon returns to the atmosphere. However, if converted into biochar through pyrolysis—at over 500 °C in the absence of oxygen—the carbon is locked into a highly stable structure that can endure in soil or other materials for hundreds of years.
How much carbon is sequestered and for how long depends on the production process and the end use of the biochar. For this reason, we operate under EBC certification, which monitors manufacturing and establishes parameters to ensure this stability.
