The Potential Of Co2 Torrefaction As Biomass Pretreatment Method

Malaysia is one of the world largest palm oil producer, where its processing is producing a large amount of biomass waste. There is a huge potential in its utilization as an energy source, as not only the amount of waste is reduced, the dependency on the fossil based fuel will also be reduced as wel...
