You’d never guess these gorgeous lamps are made from bioplastic

High-end lamps with thin elegant forms are made of metal. But a new lighting series from the London-based design studio Industrial Facility is composed of a bioplastic derived from castor oil. The lamp, called Pastille, is simple by design: just a hand-sized circle suspended from a single post. Even its insides contain only the bare essentials, with a single LED hidden inside the round disk. A mirror and plastic diffuser help that single LED do the work of a full array, while making the lamp more energy efficient.
