Our Mission

To transform waste gas streams into affordable, biodegradable materials while creating a positive environmental impact.

Mango Materials will be closed on Monday, August 21 to enjoy the total solar eclipse!

Biopolymers From Waste Methane Gas

Mango Materials Featured on VOX

VOX stopped by to talk with Mango Materials about how we are going about changing the world. Conventional plastic sticks around in landfills and oceans for several hundreds of years, and is also produced using petroleum, a raw material that not only is limited, but has numerous competing uses. Mango Materials, a Larta alumnus company has developed a process that produces biodegradable plastic using waste methane, a potent greenhouse gas. Read the full story here – Planet Friendly Plastic

Mango Materials Featured in Stanford Engineering Journal

Mango Materials CEO Molly Morse is featured in this article about how harnessing methane could save our planet! Craig Criddle is on his office phone, and he doesn’t appear pleased. The Stanford professor of civil and environmental engineering responds to his interlocutor on the other end of the line in terse, clipped phrases before finally hanging up. “You know,” he says with some weariness after the call, “if you want something from somebody, it’s best not to harangue them. That’s not going to get you far.” Criddle can be forgiven some irritation with overly importunate callers. A good many people want a piece of his time these days, and he has a plentitude of irons in the fire. Among his current projects are a process that converts nitrogen waste into nitrous oxide that can “turbocharge” engines at wastewater treatment plants; a microbial battery that converts dissolved organics into electrical energy; and a facility where technologies for wastewater treatment can be tested at the pilot scale.

Changing Cities: A Lottery That Helps Save The World

ABC was covering Mango Materials as they tried to win the Postcode Lottery worth $500,000 Euros ($630,000 USD). Read the Full Article Here – Changing Cities: A Lottery That Helps Save the World As a Ph.D. at Stanford University, Molly Morse came up with an innovative way to make biodegradable plastic. She felt like she had a world-changing idea, but needed the funding to make the idea a reality. She just got a big boost to making that happen. As part of the Clinton Initiative in New York on Sept. 23,  Molly Morse and her company Mango Materials took home the 2012 Postcode Lottery’s Green Challenge, beating out more than 500 entries of projects aiming to reduce CO2 emissions entered in the world’s largest environmental innovation prize.  Thanks to the Postcode Lottery, Morse now has $630,000 to do help rid the world of petroleum based plastic. Her process utilizes bacteria to turn methane into a biodegradable plastic, a material that can be used for almost anything made of plastic, which in today’s world is almost anything. After use, Morse’s plastic offers a better alternative to petroleum based plastic, because it can be sent to a landfill or digester and and turned back into biodegradable plastic without adding any CO2 emissions into the atmosphere....

From Methane to Plastic to Methane, Without Waste

The New York Times covering Mango Materials and their winning of the Postcode Lottery Green Challenge competition.  Read the full article here. Imagine that you could go online and rent something in your neighbor’s garage rather than buy something new that you will need to use only a few times a year. Or that you could use microwave technology to transform timber residue or other waste biomass into a valuable industrial material like graphite. Those were just two of the 50-plus entries in this year’s Postcode Lottery Green Challenge, an annual competition that awards the world’s largest prize for sustainable entrepreneurship. This year’s $630,000 check went to Molly Morse, chief executive of Mango Materials, a California-based startup that makes a biodegradable plastic from methane, a powerful greenhouse gas. Dr. Morse, who recently earned her doctorate in civil and environmental engineering at Stanford, says her company uses a closed loop process to produce some of the most affordable bio-based and biodegradable plastics...
