How it works
The mill supplies the residue. Aventra takes care of the rest.
Our model is designed so the mill captures value from vinasse without diverting capital and attention from its core business — sugar, ethanol and power.
The journey
From first contact to an operating plant
01
Assessment
We analyse vinasse and filter cake volumes and characteristics, the harvest calendar, existing infrastructure and gas offtake routes (pipeline, CNG, industrial consumers).
→ Potential and revenue estimate
02
Business model
We present the most suitable structure — typically Aventra invests in, builds and operates the plant, and the mill is paid for supplying the residue and/or shares in the results. No capex for the mill.
→ Commercial proposal
03
Development and permitting
Basic engineering, environmental permits, gas and co-product sales contracts, and project financing.
→ Final investment decision
04
Construction
EPC execution with Renova engineering and Paques biodigestion technology, with process-safety management from the design stage.
→ Commissioned plant
05
Long-term operation
Aventra's operations centre runs the plant 24/7, with a lean local team and shared specialists. Regular production and performance reporting to the mill.
→ Biomethane · CO₂ · Biofertiliser

What the mill gains
Benefits for the mill
New revenue
Payment for the residue and/or a share in the results of an asset that requires no capital from the mill.
Better vinasse management
Lower organic load and odour, with a biofertiliser that keeps the potassium for fertigation.
Decarbonisation
Reduced methane emissions and decarbonisation credits (CBIOs) attributable to the biomethane.
One partner
Development, construction, financing and operation with a single party accountable for results.
And once operation begins?
This is where Aventra differs most. Our thesis is to be the sector's operator of choice: the asset is the entry point, but long-term value lies in operating it well — with a central structure serving several plants, shared maintenance, centralised control and continuous optimisation.
For the mill, that means a plant that produces steadily through the season, clear reporting, and a partner that stays present long after commissioning.
Shall we assess your mill's potential?
The initial assessment is free and without commitment.
