By Brazil Stock Guide – Brazil’s state development bank BNDES approved a R$85.8 million direct investment in Bioo Investimentos e Participações S.A., the circular-economy company that converts agro-industrial waste into biomethane and other high-value bioproducts. The operation, disclosed by the bank’s press office, is carried out through BNDESPAR, the bank’s equity-investment arm.
The transaction gives BNDES a 19.9% stake in Bioo and is part of the bank’s renewed strategy to deploy equity capital into climate-oriented and innovation-driven companies. Bioo operates as a biosolutions platform that processes organic waste and converts it into biomethane, biogenic CO₂ and biofertilizers for the Brazilian industrial and energy sectors.
The investment — combined with additional capital from Flying Rivers Capital — will finance the development of two new Integrated Waste Treatment Centers in regions with abundant residue supply and rising demand for renewable energy. Bioo’s first commercial plant, located in Triunfo in southern Brazil, began delivering biomethane to state-owned Sulgás in the second half of 2025 under a long-term supply contract.
BNDES President Aloizio Mercadante said the investment strengthens the country’s energy transition ambitions. “With this investment, BNDES contributes to a just ecological transition by promoting a more sustainable destination for residues. Each biomethane plant could reduce CO₂ emissions equivalent to the yearly energy consumption of up to 20,000 homes,” he said.
Bioo CEO Maurício Cótica highlighted regulatory momentum for the fuel. “Brazil’s biomethane market is at an inflection point following the approval of the Future Fuels Law and the new biomethane decree. The arrival of another reference investor like BNDESPAR — together with Flying Rivers Capital — reinforces our thesis and allows us to replicate the Triunfo model in new regions,” he said.
The project is part of the Brazil Investment Platform for Climate and Ecological Transformation (BIP), a government-led initiative connecting climate-aligned projects to domestic and international capital. BIP currently includes 16 projects with an estimated investment pipeline of US$23 billion.
