Methane-based biodegradable PHA biopolymer pellets for sustainable plastic substitution
Mango Materials produces polyhydroxyalkanoate (PHA) biopolymer pellets from waste methane gas, offering a biodegradable plastic substitute for food and beverage companies. The proprietary platform delivers injection-molding, fiber, film, and 3D printing grades that enable carbon sequestration and circular end-of-life through biodegradation or recycling.
Overview
Mango Materials has developed a proprietary platform that converts waste methane gas into polyhydroxyalkanoate (PHA) biopolymer pellets, providing a sustainable alternative to conventional plastics. This solution is designed for food and beverage companies seeking to reduce their carbon footprint and address plastic pollution. The methane-based PHA formulations enable carbon sequestration and support a circular end-of-life through biodegradation or recycling.
The technology offers multiple product grades including injection-molding, fiber, and film formulations, with a 3D printing grade currently in development. By leveraging cheap waste methane as a feedstock, the platform aims to make PHA cost-competitive with traditional plastics while delivering superior environmental benefits.
Technical specifications
Key features:
- Proprietary methane-to-PHA conversion platform producing biodegradable biopolymer pellets
- Multiple formulation grades available: injection-molding, fiber, and film, with 3D printing grade in development
- Carbon sequestration capability through waste methane utilization
- Circular end-of-life options through biodegradation or recycling
- Drop-in compatibility with existing supply chains
Environmental performance based on life cycle assessment:
- Total energy requirement of 37.4 MJ/kg PHA from waste methane, compared to 41.9 MJ/kg PHA from corn feedstock
- Global warming potential as low as -6.06 kg CO2 equivalent when using waste methane feedstock
- Global warming potential of -0.1 kg CO2 equivalent when using corn feedstock
- Demonstrated superior environmental benefits versus corn-based PHA production methods
Technology readiness level
The technology has progressed from lab scale to pilot scale, with successful trials completed across injection-molding, film, and fiber formulations. Mango Materials is actively seeking brand partners to expand prototyping and launch products using YOPP+, their methane-based PHA formulation. The company is working to determine optimal formulations for food and beverage applications and to identify the best route for market entry. Off-take agreements with industry partners represent the next step toward commercial deployment.
