Creating renewable plastics that don't cost the Earth

Imagine a future where packaging is made entirely from waste material and biodegrades to harmless by-products. Or where your home's cavity wall insulation foam is made from captured CO2 emissions. Or where construction materials, vehicle components and engineering plastics are sophisticated biological composites comprised of tough cellulose fibres embedded in naturally derived polymers.
