According to a CNBC report, shrimp-shell-based packaging could be  the latest bio-plastic material to enter the market via a California-based  startup called Cruz Foam.
“What we’ve done is really built a process which allows us to  take this waste and essentially manufacture and turn it into large-scale  replacements for plastics,” John Felts, CEO of Cruz Foam, told CNBC.
Made from chitin, a material found in shrimp shells, insects, and  fungi, it is biodegradable, easily compostable, or it will just degrade quickly  in a landfill. Felts calls it “earth digestible.” Since it is made from waste,  the costs are lower than other biomaterials. 
“We scale with existing manufacturing, and that has allowed  us to reach economies of scale and cost very quickly,” added Felts.
The company already works with Rivian and Whirlpool, and investors see significant  opportunities.
                        
But this is a big field, with other companies producing packaging  from natural materials like seaweed, mushrooms, waste wool, and recycled pulp,  among others.
