Mango Materials is a biomanufacturing company that converts waste methane - the same gas that vents from landfills and wastewater plants - into biodegradable polyhydroxyalkanoate (PHA) pellets sold under the YOPP brand. The pellets replace conventional plastics in fibers, films, rigid goods, and 3D-printing feedstock, and they fully biodegrade in soil, freshwater, and marine environments.
Dr. Molly Morse is the CEO and co-founder of Mango Materials, a Vacaville, California-based startup that turns waste methane into biodegradable PHA biopolymers. Founding the company in 2010 on the back of her Stanford PhD research, Morse has spent over a decade building a circular bioeconomy solution that converts a potent greenhouse gas into a commercially viable plastic replacement — branded as YOPP pellets. She has won the Postcode Lottery Green Challenge (2012), the C3E Entrepreneurship Award (2018), and was selected as an Unreasonable Fellow in 2022.
