Hydrothermal Liquefaction Of An Industrial Biomass Waste: Brewer’s Spent Grain (Bsg)

This research examines the use of hydrothermal liquefaction (HTL) process for a treatment of biomass industrial waste. Brewer’s spent grain (BSG) is a source of lignocellulose that has a potential to be used for chemicals and fuels production, thereby reducing the reliance on fossil sources. There...
