Objective
The project’s overall objective is to develop CO₂ capture technologies based on synthetic zeolites from real gas streams derived from anaerobic digestion processes, as well as biotechnological strategies for the bioconversion of carbon dioxide (CO₂) and methane (CH₄), the main components of biogas, into high added-value biobased products, such as polyhydroxyalkanoate (PHA), microbial protein (SCP, Single Cell Protein) and biomethanol. In addition, the project will assess the application of bacteriophages as a biocontrol strategy for in situ biogas upgrading, in order to reduce microorganisms that produce interferents in CO₂ capture processes.
Activities
- Biogas upgrading with bacteriophages and CO₂ capture
- Accumulation of PHA from gases
- Bioconversion of gases into proteins
- Biological production of methanol from methane
- Technology transfer
- Dissemination and communication
- Management and coordination
Results
- Selective capture of CO₂ versus CH₄ using synthetic resins, together with 80-100% regeneration of the adsorbent material.
- Validation of PHA accumulation with HOB bacteria from gases derived from acidogenesis (CO₂ and H₂) and organic acids, using Cupriavidus necator.
- Validation of a DES, deep eutectic solvent, biobased, as a sustainable alternative for the effective recovery of PHAs.
- Valorisation of 100% of CO₂ and 50% of CH₄ in the process of bioconverting biogas into protein through the use of an adapted coculture (cyanobacteria + methanotroph).
- Validation of protein production from CO₂ and H₂ with HOB bacteria.
