Cardboard might not strike you as the most practical material for roofing, especially in a country that sees monsoon rains, like India. But a team that includes Canadian chemist Dr Heather Buckley, the Associate Director of International Partnerships at the Berkeley Center for Green Chemistry, at the University of California, Berkeley, may have found a way to make it work.
Dr. Buckley, working with entrepreneurs in India, has found a simple additive that can be added to cardboard-like panels made from a pulped cardboard mixture, that makes them sufficiently water-resistant that they can be used in roofing tiles for simple dwellings.
The tiles are robust, durable, and superior to the corrugated steel sheeting or asbestos-concrete panels that are most often used in many parts of India now.
