Resum:	Anaerobic digestion is a biological process running under anaerobic conditions in which a consortium of microorganisms breaks down complex biodegradable organic matter mainly to methane (50 to 80%) and carbon dioxide (30 to 50%): biogas. The hypothesis of the SQUEEZER project is that it is possible to further improve the process of anaerobic digestion: i) by increasing the methane content in the biogas through the addition of nanomaterials in the anaerobic digester and ii) by the catalytic conversion of part of the carbon dioxide present in the biogas to methanol. Therefore, the main objective of the project SQUEEZER is to maximize the energy that can be obtained from an anaerobic digestion process by means of nanotechnology. The methodology used in this project includes, on one hand, batch and continuous lab scale studies of anaerobic digestion of sewage sludge and source-selected organic fraction of municipal solid waste amended with nanoparticles, coated nanoparticles and combination of them to explore synergic effects of these nanomaterials to improve methane content or biogas production and a scale-up process to pilot plant (100 L) with selected nanoparticles and waste. On the other hand, the conversion of carbon dioxide to methanol through green hydrogen using pressurized packed bed plug flow reactors with nanocatalysts will be optimized. Initially, a systemic gas will be used to avoid interferences, but SQUEZEER aims to finally test catalytic conversion by using real biogas. Finally, a preliminary environmental and techno-economical assessment will be presented. Energy and mass balances will be prepared to define a complete Life Cycle Inventory and perform the greenhouse gasses accounting of the whole process. In summary, project SQUEEZER is scientifically sound and is based on previous results from our group, being aligned with the current strategies of the European Union related to ecological transition, sustainability, climate change and Circular Economy.
