The study looked at how to make a biorefinery that uses both 1st and 2nd generation ethanol production. They used a special process with oat husks and thin stillage to make products like lignin and protein-rich biomass. By adding 10 tons of oat husks to the process, they increased ethanol production from 5.2 to 7.5 tons per hour, along with making 1.6 tons of lignin and 7.6 tons of fungal biomass. Selling the fungal biomass as feed and food made the plant more profitable compared to a regular ethanol plant.
