Seaweed-biofuel idea gets airing

Turning seaweed into a biofuel and using it to reduce greenhouse gas emissions is one of the ideas under discussion by experts in Wellington this week.

About 250 scientists, resource managers and others from around the world are at the fifth Asian-Pacific Phycological Forum.

One technique being discussed is how macro-algae - or seaweed - can be used to battle climate change.

Ik Kyo Chung from Pussan National University in Korea is studying the potential of marine algae to sequester carbon dioxide as a way of mitigating climate change.

He says seaweed can absorb carbon dioxide. He says people should cultivate marine forests of seaweed to help provide a solution to climate change.
