Styrofoam takes over 500 years to decompose—and yet we still use it for insulation. The Cruz Cool cooler, which can insulate frozen goods for 48 hours, is made out of chitin, a polymer that’s found in fungi, insects, and shrimp. But the real difference is how it’s produced. Typically, eco-friendly alternatives to styrofoam come in odd shapes and sizes that flummox supply chains. Parent company Cruz Foam compounds the chitin with other ingredients into large flat pellets that feed into a partner’s current processing plant. That’s how Cruz Foam is already partnering with Atlantic Packaging, an industry leader.
