[74]. In a cascade biorefinery approach, these materials were further used for animal feed and fermentation of acetone, ethanol,
butanol, and 1,2-propanediol, all coming from the same initial
material (Fig. 8). Producing multiple products reduces the biomass
waste and thus increases exergy delivered to users in products.
