Why we chose bioreactors rather than covered lagoons
Covered lagoons dominated the first generation of vinasse biogas. We explain why AVENTRA chose a different path.

The comparison between covered lagoons and bioreactors should consider initial investment, footprint, process control and costs throughout operation. AVENTRA’s choice prioritises a configuration consistent with its projects’ control and performance objectives.
Closed high-performance vertical bioreactors address these issues. The process is controlled, production is predictable and the footprint is a fraction of that of a lagoon. For a mill, this means a partner that delivers gas within specification, harvest after harvest.
