Dr Kerry Kirwan is an Associate Professor at WMG, University of Warwick. He specialises in sustainable materials and was recently involved in building Eco One, an environmentally friendly racing car made from recycled materials and fuelled by biodiesel derived from waste food products, including chocolate and beef fat. Eco One was featured as one of TIME Magazine’s Top 50 Global Inventions of 2009. He has developed the biodegradable "Sunflower Phone" that allows mobile phone users to grow plants from their discarded mobile phone cases through the encapsulation of a small seed in a visible window, subsequently prompting them to dispose of electronics in a responsible manner.
