Process options for converting renewable feedstocks to bioproducts

This paper discusses the relative advantages of different process options to convert renewable feedstocks ( carbohydrates, vegetable oils, terpenes and lignocellulosic materials) into valuable chemicals and polymers. Three process options are considered: ( 1) via degraded molecules, ( 2) via platform molecules, ( 3) via one-pot processes. These routes can all be integrated in a biorefinery scheme which maximises the value derived from biomass. These process options are illustrated by selected examples underlining the green chemistry value of process options 2 and 3. Stress is laid on new value chains adapted to biomass composition and on the use of recyclable heterogeneous catalysts that lead to waste minimisation and decrease the processing cost of renewables.
