Brooklyn-based design studio Crème uses home-grown vegetables to produce a sustainable alternative to disposable coffee cups. The Jun Aizaki-led studio grows gourds in moulds to create the biodegradable cups, which go by the name HyO-Cup. It claims that these cups can be manufactured on a mass scale – offering a more environmentally friendly alternative to paper coffee cups, which are typically lined with unsustainable plastic polyethylene.
