Amazon-backed startup Windfall Bio said it successfully scaled production of methane-eating microbes, a milestone in sustainable fertilizer development. Windfall Bio said fermentation of the microbes reached 17,000 liters, representing commercial-scale production of its methane removal solution. The microbes consume methane and transform into nitrogen-rich biomass that can be processed into high-value organic fertilizer. Windfall is testing its organic fertilizer as it pursues regulatory approvals. It is also providing large samples to customers to establish a market. This achievement not only demonstrates our ability to deploy a nature-based solution at scale but also redefines how industries can turn harmful methane emissions into valuable products like organic fertilizer, Josh Silverman, co-founder and CEO of Windfall Bio, said in a statement.
