Lignocellulosic biomass should not be used as energy feedstock only. The extractable phytochemicals present in lignocellulosic biomass from perennial industrial crops (PIC) can be used in the pharmaceutical, cosmetic and chemical industries. A production residue, so-called “post-extraction biomass”, can be later used as energy feedstock. Therefore,...
