Algal Biomass Does it save the world? Short reflections
The technical potential of macro- and micro-algae for biomass production and greenhouse gas abatement has been recognised for many years, given their ability to use carbon dioxide and the possibility of their achieving higher productivities than land-based crops. Biofuel production from these marine resources, whether use of biomass or the potential of some species to produce high levels of oil, is now an increasing discussion topic. There are multiple claims in this sector but the use of algae as an energy production system is likely to have to be combined with waste water treatment or uptake of nutrients and minerals from polluted natural resources and co-production of high value products for an economic process to be achieved.
