Your fast food burger may one day come in an algae container. Alginsulate is a packaging and insulating foam created by puffing up dried brown algae. It is biodegradable and not appetizing to mice and insects, which is a problem for packaging made from corn and potatoes. Alginates are the same seaweed derivatives that are used to thicken ice cream. There’s a pilot plant now in operation to produce Alginsulate and more applications are being considered.
