Footprint has snared some huge clients for its big idea: plant-based food packaging that’s biodegradable, yet durable enough to perform like plastic. Its bowls, trays, straws, six-pack rings, and other packaging are being used or tested by giants like McDonald’s, Tyson Foods, and Molson Coors. The compostable materials can withstand extremes of hot and cold, and Footprint estimates its products have diverted 60 million pounds of plastic from the environment. While it doesn’t report revenue figures, the company says it expects 70% year-over-year sales growth in 2020.
