Inliterature, yields of mono-phenolic compounds are reported that rarely exceed 5-6 %[1,2]. Consequently, the main practised option for lignin is the use as fuel forgenerating heat.LIBRA is a new Lignin BioRefinery Approach based upon bubbling fluidised bedpyrolysis technology [3] to valorise lignin in a phenolic bio-oil and bio-char forapplications such as phenol subtitutes in wood-resins, high-value phenolics asprecursors for pharmaceutical, food, and/or transportation fuel applications, soilimprover, growth enhancer and filtration material.Three lignins derived from hardwoods, from a mixture of grass and straw, andfrom annual plants as a raw residue from the production of bio-ethanol have beenprocessed according to LIBRA to investigate their potential as renewable feedstocksfor valuable products.155
