Project description

PUMA will establish an innovative platform for identification and upgrading of lignin fractions by utilizing aromatic side streams in the most efficient and economical way. Mild/catalytic methods will be used for depolymerisation and refining in order to produce synthons for resins/polymers, composites, activated carbons/carbon foam and high-price bulk phenolics of broad and high industrial relevance and scale. For this, the PUMA consortium combines the essential expertise from biorefining, process design and industrial biotechnology in order to valorize an unused CO2-neutral source for energy carriers and value-added bio-based aromatics and products.
