Bright Renewables Expands to Brazil: Biogas Upgrading & CO2 Liquefaction Project with Bioo

19 May 2026

Bright Renewables has signed a project to construct a biogas upgrading plant including CO2 liquefaction technology in Triunfo, Rio Grande do Sul, south of Brazil. This initiative is in collaboration with Bioo: a biosolution platform and a joint venture between Sebigás Cotica and EB Capital. Funded by Bioo and a substantial credit from the National Bank for Economic and Social Development (BNDES), backed by the Climate Fund, the project aims to produces biomethane and food-grade liquid biogenic carbon dioxide (CO2) from agro-industrial waste.

Commissioning of the project is completed and will reduce CO2 emissions by 14,000 tons annually.

Technology insights

Incorporating a biogas upgrader with membrane technology, this project will upgrade 2,500 Nm³ per hour of biogas into biomethane, a renewable natural gas. It also features a CO2 liquefier, with a production capacity of up to 2,000 kg of CO2 per hour. Utilizing natural carbon dioxide as a refrigerant in the liquefaction process effectively reduces the carbon footprint. The integration of a CO2 liquefier improves the carbon intensity (CI) score, a key metric quantifying emissions per unit of energy, and the efficiency of the biogas upgrader.

The plant targets daily production of 30,000 cubic meters of biomethane for high-pressure gas grid injection, food-grade liquid bioCO2, and organic fertilizers.

“At Bright Renewables we are gratified to see our technology being utilized in Brazil, a country with substantial potential for biomethane production. Our engagement in this region underscores our commitment to leveraging technology and advancing sustainable energy practices.”

Impactful partnership

Evonik, providing the hollow-fibre membranes for the upgrading of the biogas, a technology integral to the system, shares their perspective on the project’s significance: “This project in Brazil, alongside our other projects with Bright, exemplifies our vision of building impactful partnerships across the globe. These membranes represent not just a product but a vital component in collaborative, worldwide efforts fostering a cleaner energy future,” comments Jennifer Dörper, Business Manager SEPURAN® Green at Evonik’s High Performance Polymers business line. It’s noteworthy that a previous project with Bright was Evonik’s 1000th.
