Beyond Meat and Impossible Foods are getting into the fast-growing market for plant-based chicken.

REDWOOD CITY, Calif. - Impossible Foods is partnering with a major meat processor to increase its capacity. Demand for meat substitutes like Impossible's has been growing as people try to reduce their meat intake for health or environmental reasons. Teaming up with OSI, a private company that produces food and processes meat, should help Impossible keep up with future surges in demand and allow it to scale quickly. Impossible and OSI have essentially set up a replica of the plant-based food company's Oakland production facility within the Chicago plant, explained Sheetal Shah, senior vice president of product and operations for Impossible. Others, including Dunkin' and Tim Hortons, serve meat substitutes made by Beyond Meat, Impossible's main competitor.
