A ground-breaking Swansea University project is using microalgae to explore how to reuse waste while increasing food production. Microalgae are microscopic photosynthetic cells found naturally in the oceans and lakes. But Swansea scientists are now using a more novel source of nourishment to grow them – unwanted nutrients from food waste. They are now about to embark on feed trials with colleagues in France to test their cultivated algae as an alternative to soya protein.
