Amazon-Backed Startup Wraps Pilot for Methane-Munching Microbes

An Amazon.com Inc.-backed startup has successfully tested methane-eating microbes that can reduce dairy farm emissions.

Windfall Bio has completed a pilot with Straus Family Creamery and California-based Correia Family Dairy where its microbes — known as mems — removed more than 85% of the potent greenhouse gas from the farm’s manure lagoon. The test shows a novel pathway to reduce the planet-warming impact of animal agriculture, which is responsible for nearly a third of all methane emissions.

The startup’s mems consume methane and transform it into organic fertilizer, which can help cut emissions while creating a byproduct that can ...
