Chemical and thermochemical approaches for sustainable energy production starting from waste biomasses

The present work aims the valorisation of low-cost lignocellulosic feedstocks, as natural (Posidonia Oceanica) or industrial (paper mill sludge) wastes, for bio-fuel production respectively through chemical and thermochemical processes. In particular, Posidonia Oceanica has been chemically converted through a one-pot alcoholysis reaction for the production of alkyl levulinates, on the other hand, the paper mill sludge, one of the most abundant waste produced by the paper industry, was investigated as possible feedstock for syngas production through the gasification process. In conclusion, this work proposes the valorization of natural lignocellulosic residues and industrial wastes as low-value feedstock.
