Mango Materials’ Vacaville production facility will host a new state-of-the-art gas fermentation pilot unit acquired by BEAM Circular, integrating with the company’s pioneering methane-to-PHA biodegradable polymer platform and expanding access to scale-up capabilities for gas fermentation technologies.

Mango Materials is tackling plastic pollution by using a microbial process to convert waste methane, such as biogas from wastewater treatment, into biodegradable, often carbon-negative polyhydroxyalkanoate (PHA) under its YOPP™ brand, with a goal to scale up production to compete in the global plastics market.

By converting waste methane into biodegradable PHA polymers, Mango Materials is paving the way for a circular textile future—offering a bio-based alternative to conventional polyester that can enter a soil- or landfill-friendly life cycle.

Mango Materials is developing an innovative biomanufacturing process that converts waste methane from sources like wastewater treatment plants into biodegradable plastic (PHA), tackling both plastic pollution and potent greenhouse-gas emissions simultaneously.

Molly Morse was recognized in Biofuels Digest’s Bioeconomy 500 for 2025, celebrating global leaders shaping the future of sustainable innovation. The acknowledgment highlights Mango Materials’ pioneering work turning methane emissions into biodegradable PHA materials that support a circular, low-carbon economy.

Mango Materials CEO Dr. Molly Morse joined U.S. Energy Secretary Chris Wright at Berkeley Lab to share the company’s vision for a sustainable plastics future, featuring biodegradable YOPP pellets and product prototypes. The visit highlighted Mango Materials’ role in advancing the bioeconomy through collaborative, science-driven innovation.

Molly Morse, founder of Mango Materials, transforms methane into biodegradable plastics, turning a greenhouse gas into a sustainable resource. This episode explores her journey from research to building a climate-tech startup with real-world impact.

In the podcast “From Gas to Glam,” Molly Morse, CEO and co-founder of Mango Materials, details how her company turns methane into PHA bioplastics, discusses partnerships with wastewater facilities and brands, and lays out the challenges and opportunities of scaling biodegradable polymer production

Mango Materials is developing a process to convert methane from waste (e.g. biogas at a wastewater plant) into the biodegradable polymer PHA at scale, aiming for a distributed manufacturing model to rival petroleum plastics.

Mango Materials is heading a BioMADE-funded project (running through June 2026) to scale a methane-to-PHA biomanufacturing process, aiming to enable decentralized, low-resource production of biodegradable plastics.
