Seaweed Cups: Food as Packaging

The New York Times: “A growing number of entrepreneurs and researchers are working to turn foods like mushrooms, kelp, milk and tomato peels into edible — if not always palatable — replacements for plastics, coatings and other packaging materials.” For example: “The United States Department of Agriculture … has developed a material from milk protein that can be used to line pizza boxes, encase cheese or create, say, soluble soup packets that can simply be dropped in hot water. The product could even serve as a substitute for the sugar used to coat cereal flakes to prevent them from going soggy too fast.”

“Over the past several years, governments have quietly bankrolled efforts to develop packaging from food. The European Union, which underwrote a project to develop coatings from whey and potato proteins from 2011 to 2015, estimates that the global market for so-called bioplastics is growing by as much as 30 percent each year.”
However: “Nestlé says it wouldn’t want its demand for packaging to reduce the food supply, given widespread hunger … Few, however, are begging to eat the peels left after tomatoes are processed. A group of researchers in Italy has used them to develop a lining for cans.”

“A British start-up called Skipping Rocks Lab is taking matters into its own hands. The company has developed a packaging it calls Ohoo from edible seaweed, and is building a machine to produce containers from Ohoo to hold water, juices, cosmetics and other liquids on the spot. A juice bar, for instance, could create a container with each order.”
