Expertise

Bio2E expertise covers a range of biomass, bioprocesses and environmental applications.

Biomass

• Agricultural residues and animal waste
• Food industry waste
• Household waste
• Effluents: vinasses, urban and industrial wastewater...
• Sludges from wastewater treatment plant
• Macro and microalgae

Bioprocesses skills

Fermentations:

• Anaerobic digestion

Bioconversion of biomass with high organic content into biogas (methane) and a residue called digestate, through the action of microorganisms in the absence of oxygen.

• Biomethanation

Bioconversion of gases (CO2, H2) into biogas (methane) through the action of microorganisms. It allows for example to valorize the non-CH4 gases produced by anaerobic digestion into an additional quantity of renewable energy without using additional biomass, and without emitting CO2 into the atmosphere.

• Purple phototrophic bacteria

Fixing of CO2 by purple phototrophic bacteria, able to use a range of gaseous electron donors, such as H2 or H2S (contained in fermentation liquid residues), under anaerobic-illuminated conditions, while producing biomass and proteins.

• Biological pretreatments

Others:

• Composting

Biological conversion of fermentable matter that occurs in an oxygenated environment.

• Photobioreactors

Depollution by phototrophic microorganisms.

• Aerobic treatments

Wastewater and effluents purification by microorganisms.

Environmental applications

• Renewable energies (biomethane, biohydrogen)
• Bio-based molecules (VFAs, proteins)
• Amendments (digestate, compost)
• Water purification and reuse
• CO2 Sequestration
