Oh Soo-young reports for Arirang News in South Korea that, while algae are damaging local ecosystems, numerous researchers in Korea are turning the crisis into opportunity. The number of patent applications for algae-based technologies has risen to roughly 50 per year – a fifty-fold increase from ten years ago.
A Korean research team claims to be the first in the world to produce biodiesel using a cost-effective and environmentally friendly method that involves placing naturally occurring algae in a special cultivation system in the sea. “With our technology, carbon dioxide in the air and algae-producing chemicals in the sea are absorbed. These substances, which are considered environmentally damaging, are taken care of through the process. With some adjustments, this technology could be applied to rivers and lakes, as well as to purify the air and waters.”
