The Effects of Halogenated Compounds on the Anaerobic Digestion of Macroalgae

Fermentation, 2020
The urgent need to replace fossil fuels has seen macroalgae advancing as a potential feedstock for anaerobic digestion. The natural methane productivity (dry weight per hectare) of seaweeds is greater than in many terrestrial plant systems.
