Methane based biodegradable bio plastics for synthetic fibre replacement

Mango Materials focuses on the production of PHAs from methane and biopolymer formulation. Typically, plastic pellets (also known as chips) are melted down to make something — film for plastic bags, or fiber for yoga pants, for example. At Mango, biodegradable PHA serves as the backbone for an alternative plastic pellet, which is optimized for biodegradability while preserving optimal mechanical characteristics.

Highlights and sustainability benefits

The products naturally biodegrade back to methane, thus creating a circular system. Use of biodegradable plastics significantly reduce the need for fossil based plastics in textiles, thus protecting the environment from the impacts of their production and disposal.


In 2019, Mango Materials was named one of the Next 50 Companies to Disrupt the World by Biofuels Digest The company is also listed on the Global Cleantech 100.

About the Work

Mango has its own fermenter design that can handle the explosive mixture of methane and oxygen used to produce PHAs. Mango Materials' bioplastic naturally biodegrades back to methane; thus, the process is a closed loop, cradle-to-cradle solution.

About the Innovator

Mango Materials, a California-based startup company, produces biodegradable plastics from waste biogas (methane) that are economically competitive with conventional petroleum-based plastics. Mango Materials uses excess methane gas from wastewater treatment plants or landfills to produce pellets of polyhydroxyalkanoate (PHA), a valuable polymer that is converted into a variety of high-margin or high-volume, eco-friendly plastic products such as children’s toys, electronic casings, water bottles, and food packaging containers.
