Green Revolution: Biomass

6 minutes 52 seconds

Now Playing As: Captioned (English) (change)

Researchers explore how different types of biomass can be used to produce fuel. One researcher is building reactors to grow algae used to create biofuel. A different study examines how leafcutter ants break down biomass in order to convert cellulose in plants to a fermentable sugar used to make ethanol. Finally, an engineer uses chemistry and heat to turn sawmill waste into bio-oil and gasoline.
