Biomethane infrastructure
Intelligent infrastructure for renewable molecules.
AVENTRA is developing its first biomethane plant for Brazil’s sugar and ethanol industry. Our model integrates development, financing, construction and long-term operation.

Integrated capabilities
What AVENTRA does in each project
We bring six capabilities under one responsibility: engineering and O&M, process biotechnology, a digital platform and data science, origination and commercialisation, logistics and distribution, and regulation, permitting and certification. They connect project development to plant operation and biomethane delivery.

Technology and process control
High-performance vertical bioreactors, process biotechnology and automation control biodigestion. The result is stable production and better use of vinasse and filter cake.
Long-term responsibility
AVENTRA is responsible for development, permitting coordination, operation and maintenance, sales contracts and distribution logistics, with responsibilities defined for each project.
Portfolio intelligence
The planned digital architecture brings together operating data, applied research and predictive maintenance to support operations and carry lessons from the first project into subsequent ones.
How it works
From vinasse to biomethane in five steps
01
Substrate reception
Vinasse and the other substrates defined for the project are received and prepared for biodigestion.
02
Biodigestion in a vertical bioreactor
Microorganisms convert organic matter into biogas in closed high-performance vertical bioreactors under controlled process conditions.
03
Treatment and upgrading
Biogas undergoes H₂S removal, CO₂ separation and treatment to meet the applicable biomethane specification.
→ Biomethane
04
Co-product utilisation
The plant is designed to recover biogenic CO₂ and return digestate to the fields as biofertiliser.
→ Biogenic CO₂ · Biofertiliser
05
Operation and optimisation
The operating model provides for 24/7 plant supervision by AVENTRA’s Operations Control Centre and support for process adjustments.

From mill to tank
From vinasse to delivered biomethane.
AVENTRA’s projects are designed to convert vinasse and filter cake from ethanol mills into biomethane to replace diesel in heavy transport and industrial applications.
Under AVENTRA’s model, the integrated production system is its responsibility: vinasse reception, biomethane production, sales contract management and logistics through to final delivery. The supply strategy considers location, production seasonality, customer demand, logistics and the supply alternatives provided for in each contract. The mill has a single partner, from production to delivery.
