This single-use barbecue is the winner of the 2017 Danish Design Award and is protected by several patents. It is made entirely from biodegradable materials, including bamboo, lava stone, recycled cardboard and compressed bamboo charcoal. It is ready to use in five minutes and can cook food for around an hour. CasusGrill is a more sustainable alternative to traditional disposable barbecues, as it reduces the use of charcoal and the associated carbon dioxide emissions.
