Biogas production from food wastes, sludge, or agricultural residuals is easy to produce. The bacteria eat these materials in an oxygen-free vessel and produce biogas or biomethane. But, what to do if the materials are not degradable such as wood or plastics? Our PhD student Konstantinos Chandolias worked on this topic, where the materials first gasified (burned with little oxygen) to produce syngas that is mixture of hydrogen, carbon monoxide and CO2. He gave this syngas to the bacteria to eat it happily and to produce biogas or hydrogen. He studied details of this process, using membrane bioreactors and to develop many technical factors. He nailed his PhD thesis today that is about "Enhanced Methane and Hydrogen production in Reverse Membrane, Bioreactors via Syngas Fermentation" and will defend it on 29 Nov. We wish him good luck.
His thesis had these papers:
1- Rapid bio-methanation of syngas in a reverse membrane bioreactor: Membrane encased microorganisms
2- Syngas Biomethanation in a Semi-Continuous Reverse Membrane Bioreactor (RMBR)
3- Effects of heavy metals and pH on the conversion of biomass to hydrogen via syngas fermentation
4- Protective effect of RMBR against syngas impurities
5- Floating Membrane Bioreactors with,High Gas Hold-Up for Syngas-to-Biomethane Conversion
