Description

Royal College of Art graduate Tessa Silva-Dawson has used cow's milk to create a natural alternative to plastic Silva-Dawson, who studied on the institution's Design Products course, aimed to replace oil-based polymers with an organic waste material that could perform in the same way. For her Protein project, she sourced waste milk from a dairy farm in Sussex, which throws away 3,000 litres of skimmed milk each week. "That's just one farm in the UK, so 3,000 litres a week is, potentially scaled up, a really big industry," Silva-Dawson told Dezeen. The production process starts similarly to cheese-making, using heat to separate the curds from the liquid whey. The curds are then dried out in an industrial dehydrator and mixed with a natural plasticiser to turn them into pellets. According to the designer, these can be used in the same way as synthetic plastics and moulded with existing machinery.
