Sierra Preta

At Sierra Preta, we turn problems into solutions. We process agricultural waste to produce high-quality biochar to increase the sustainability and resilience of local farmland ecosystems. We focus on developing decentralized and community-driven pyrolysis processes to create maximum environmental and social value locally. We are rooted to our local environment, and aim to regenerate Andalusian soils, working towards climate change mitigation and adaptation by stopping the progression of the desert in Southern Spain.
