Process schematic of different pretreatment methods of municipal green waste. Biomass with a high lignin content is pretreated using an organosolv process to break up the recalcitrant lignocellulose structure. The residue is saccharified enzymatically before the use in cultivations. Biomass with a high moisture content is separated into a liquid press juice and a solid press cake. The press juice can directly be used for cultivations; the press cake undergoes enzymatic saccharification together with the residue of the high-lignin biomass pathway after organosolv pretreatment
