This looked like one for the Ignobel awards. No, not the Darwin Awards which commemorate those who improve our gene pool by killing themselves in really stupid ways. The Igs are those annual awards for 'discoveries that cannot, or should not, be reproduced'. OK stupid too. Last year, for example, Juan Manuel Toro, Josep B. Trobalon and Nuria Sebastian-Galles won the linguistics Ignobel for determining that rats sometimes can't distinguish between recordings of Japanese and Dutch played backward.
But apparently they're serious at Warwick University, whose manufacturing group has been beavering away with the research arm of plastics firm PVAXX to develop a biodegradable phone. The Ignobel bit comes when you ask how the phones biodegrade. The answer is: bury them in compost. Once well rotted down, the cases support the growth of dwarf sunflowers. You ask three questions. What interesting applications has this for Green construction? What about the battery, screen and circuit board inside the composting phone case? and, Why dwarf sunflowers?
