Biomethane infrastructure
Intelligent infrastructure for renewable molecules.
Aventra develops, owns and operates industrial-scale biomethane plants. Vertical high-rate reactors, continuous operation and portfolio-wide digital supervision — because renewable molecules should be engineered, not merely collected.

Three pillars
Biology, engineered for industrial performance
Biology has always been able to make methane. What it has never had is industrial discipline. Aventra builds the machinery, instrumentation and software that turn methanisation into a controlled process.
Engineered process
Vertical high-rate reactors, controlled retention, tight process windows. We design for throughput and stability, not for containment.
Continuous operation
We operate what we build. Instrumentation, maintenance regimes and central supervision keep plants delivering to contract.
Portfolio intelligence
One operating platform across every asset. Data-supported methanisation optimisation and lab-to-field R&D make each plant better than the last.
How it works
From vinasse to biomethane in five steps
01
Residue intake
Vinasse and filter cake are received directly from the mill's process.
02
Reactor biodigestion
Microorganisms convert organic matter into biogas inside controlled vertical reactors.
03
Cleaning and upgrading
H₂S removal and biogas upgrading to pipeline-grade biomethane specification.
→ Biomethane
04
Co-products
Biogenic CO₂ is captured and the digestate returns to the field as biofertiliser.
→ Biogenic CO₂ · Biofertiliser
05
Operation and optimisation
Aventra's operations centre monitors the plant 24/7 and continuously tunes the process.
