An emerging rise in investment in from petrochemical majors and
governments in Asia, Europe and the Americas aims at extracting sugars
from seaweed for ethanol, advanced biofuels, drop-in fuels, biochemicals
and biopolymers.
For more than 100 years, China and Asian nations have grown seaweed
also known as macro-algae for food, animal feed, pharmaceutical
remedies, and cosmetic purposes.
Why Macro-Algae? A new study, Algae 2020, Vol 2
(October, 2010 update) finds experts from Korea, the Philippines,
Norway, the US and Chile agree seaweed grows faster than terrestrial
crops, has a high sugar content for conversion to advanced biofuels and
ethanol, absorbs more airborne carbon than land-based plants, has no
lignin, can be easily harvested compared to microalgae, requires no
pretreatment for ethanol production, can be harvested up to six times a
year in warm climates. The Algae 2020 study details emerging projects in macro-algae driving increased investment in projects around the world, as highlighted below.
