About Aventra
Aventra is a developer and holding company for energy transition projects. We structure, develop, build, operate and finance carbon capture, transport, utilisation and storage assets and bioenergy assets, in Brazil and abroad, directly or through consortia, joint ventures and special purpose companies.
We were born out of a team that has worked together since 2012 across sugar and ethanol, energy, private equity and infrastructure. That origin defines how we operate: we understand the daily routine of a mill, the logic of an investment committee and the wording of a long-term contract with equal ease.
Prospecting and structuring projects with partner mills, from the feasibility study through to the final investment decision.
Economic modelling, engineering, permitting, fundraising and negotiation with investors and lenders.
Construction, O&M and long-term offtake agreements for biomethane, CO₂ and carbon removal credits.
Business platforms
Aventra's integrated project does not depend on a single price. It stacks complementary revenues on the same infrastructure, which underpins returns and reduces exposure to any one market.
01
Biomethane sold under 10 to 20 year offtake agreements, with inflation indexed pricing. Development of anaerobic digestion, desulphurisation and upgrading units.
Output
Drop-in renewable natural gas, compatible with existing natural gas infrastructure.
02
Mills run 170 to 210 days a year. Storage and generation units extend operation into the off-season with complementary feedstocks, removing the anaerobic digestion shutdown.
Output
Firm year-round supply, a precondition for bankable offtake agreements.
03
Integrated evaporation reduces biofertiliser volume at a 10 to 1 ratio, lowering cost and simplifying application across the mill's full area.
Output
Premium co-product, savings on chemical inputs and mitigation of the vinasse liability.
04
Biogenic CO₂ captured from fermentation and from biogas supplies the food and beverage industry and low carbon fuels such as e-methanol, and also enables permanent geological storage.
Output
Liquefied CO₂, e-fuels and permanent carbon dioxide removal (CDR).
Business model
Aventra's model starts from three real problems in the sugar and ethanol sector and answers each one of them.
Challenge
Seasonality and low asset utilisation. Mills run 170 to 210 days a year, while the biomethane buyer needs uninterrupted, contracted supply.
Aventra's answer
Integrated feedstock flexibility across vinasse, filter cake and seasonal substrates, with optional storage and cogeneration to remove the shutdown.
Challenge
Operational interruptions. The off-season forces biomethane production to stop and interrupts anaerobic digestion, which depends on constant feeding to sustain microbial activity.
Aventra's answer
A modular platform that adjusts to different sizes and harvesting patterns. Phased implementation reduces upfront investment and accelerates time to revenue.
Challenge
Environmental liability. Large volumes of vinasse pose a risk of soil contamination, water pollution and methane emissions when poorly managed.
Aventra's answer
Vinasse becomes an advanced biofertiliser, which removes the disposal problem, reduces the environmental footprint and adds a valuable co-product to the business case.
Holdings
Beyond its own development pipeline, Aventra holds equity stakes in dedicated platforms, alongside partners with a proven track record in their respective sectors.
Engineered Carbon Storage
A joint venture between Aventra and Ágil Energia for the development of permanent onshore geological CO₂ capture and storage projects in deep saline reservoirs. The combination brings together professionals with direct experience in one of the world's largest CCS projects and professionals with an established track record in bioenergy.
Cross-referencing stratigraphic, petrophysical and structural information identifies deep saline reservoirs with geological viability for CO₂ storage, with significant porous thickness, high porosity and excellent seal quality. Estimated volumes place the Paraná Basin as Brazil's largest and safest onshore environment for CO₂ storage, in the same region where the country's sugar and ethanol production is concentrated.

In development
The anchor project takes around 2.5 years from early development through to commissioning, with construction completed in approximately 18 months.
Phase 01
Partnership agreement, pre-quantification and scope definition.
Phase 02
Feasibility and FEED, engineering, environmental and construction permits, financial and commercial structuring through to the final investment decision.
Phase 03
Mobilisation, equipment assembly, pre-commissioning and systems commissioning.
Phase 04
Operating licence, assisted commissioning and operational ramp up.
Governance
We operate in a highly regulated environment, with an impact on society, on the environment and on future generations. Our decisions are therefore guided by high standards of ethics, integrity and transparency.
Clear, accurate and accessible disclosure, beyond what the law requires.
Fair and impartial treatment of all stakeholders, without favouritism.
We take full responsibility for the impacts of the decisions we make.
Sustainable practices embedded in the business model.
Decisions grounded in reliable data and technical analysis. Omitting, manipulating or distorting technical, operational, environmental or financial information is prohibited.
In projects whose effects extend over decades, systems safety and public trust come before any short-term operational or economic interest.
