About us

Geo was born from the vision of a team of entrepreneurs, driven by the advancement of biodigestion technology, particularly in the European territory, and aware of the vital potential of biogas in the green and renewable energy production chain in Brazil, and consequent reduction of carbon emissions worldwide.

Since then, we have combined the concept of efficient gas generation with the potential of the Brazilian agribusiness, adapting the technology to Brazil and establishing the first industrial-scale biogas plant in the sugarcane sector.

With about two decades of experience, our technology continues to evolve constantly, with scale and competitiveness. Today, Geo stands out as a company committed to solutions using renewable carbon, including biogas production, clean electricity generation, and advanced biofuels production, designed to meet the needs of our partners.

Additionally, we are committed to providing renewable and biogenic carbon as high-quality raw material for other high-value-added products, such as Sustainable Aviation Fuel (SAF) and biomethanol.

We are driving the future of energy through renewable sources, contributing not only to the reduction of carbon emissions but also to the development of innovative solutions.

We are the energy of the future, today!
