Mango Materials
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.
