Leveraging food waste is a massive food innovation and profit opportunity
Back when she lived in California, Katrina Cornish found herself wondering about those open trucks she saw carrying big loads of ripe tomatoes. Why, she thought, weren’t the tomatoes on the bottom crushed into big red puddles.
The reason, she would later learn, is that the tomatoes were bred to have tough skins that allowed them to withstand all that weight from above.

Recently, she and her research team discovered that not only those tough tomato peels, but also crushed eggshells, can be effective replacements for the petroleum-based filler used in car tires.
“What you want in a filler is something really tough and strong,” she says. “That was why we looked at the tomato peels.”
