The Company That Turns Cow Manure and Table Scraps Into Pipeline Gas
Founded in 2017, Sevana Bioenergy builds the tanks where dairy manure and rotting food break down into pipeline-grade fuel. Then it bought the biggest one in North America for pennies on the dollar.
Divert, Inc.
Divert, Inc. is a Concord, Massachusetts impact technology company on a mission to prevent food from being wasted. Founded in 2007, it pairs data-driven prevention software with reverse logistics and a network of anaerobic digestion facilities that turn unsold and non-donatable food into renewable natural gas and soil amendment. Divert serves more than 7,800 retail and industrial customer locations - including Kroger, Albertsons, Target, CVS and Ahold Delhaize - and reached a valuation of over $1 billion following a 2026 Series C led by Mitsubishi Corporation.
ArkeaBio
ArkeaBio is a Boston climate-biotech company building the first vaccine that cuts methane emissions from cattle. The shot trains a cow's immune system to produce antibodies that travel to the rumen and suppress methanogens - the microbes that turn digestion into greenhouse gas. Livestock methane accounts for roughly 6% of global emissions, and ArkeaBio's pitch is blunt: a vaccine is the lowest-cost, most scalable way to attack that number. Backed by Breakthrough Energy Ventures and a roster of climate and ag investors, the company is moving from animal studies into full field trials, targeting a 20% methane reduction and a first product in market around 2028.
