Solving the cow burp problem

What this episode covers

Charles Brooke, program manager for enteric methane at Spark Climate Solutions, explains that enteric fermentation from ruminants is a major source of global methane, with over 80% of emissions coming from small-holder pasture-raised animals rather than feedlots. He details current mitigation strategies, including feed additives like DSM’s Bovaer (3-NOP) and bromoform from Asparagopsis seaweed, which offer variable reductions, and emerging solutions such as vaccines from Kio Bio and selective breeding programs. Brooke highlights that while feed additives are effective, their daily administration limits them to intensive systems, whereas vaccines and breeding offer permanent, pasture-compatible reductions. The conversation concludes with the significant regulatory hurdles in the US, where these products face an 8-year approval process as new animal drugs, and the need for coordinated public education to avoid consumer backlash.

    Turning Cow Burps into Clean Energy with Griffin Cherry

    Griffin Cherry, Founder and CEO of Planet.Tech, explains how his company captures methane from cow respiration using a wearable halter and nose piece system that stores gas in a backpack for later extraction during milking. He details the engineering challenges of designing durable, cow-proof hardware for 1,600-pound animals and the business model of providing farmers with new revenue streams to offset chronic unprofitability. Cherry discusses the transition from roofing sales to climate tech, highlighting the importance of rapid prototyping with 3D printing and off-the-shelf components to achieve a functional MVP quickly. The episode covers the technical validation of capture efficiency, the economic potential of selling pipeline-quality renewable natural gas, and the company's vision to become a platform for solving planetary-scale climate problems.

    Using Methane-Eating Bacteria to Combat Climate Change: A Discussion with Josh Silverman, CEO at Windfall Bio

    Dr. Josh Silverman, CEO and founder of Windfall Bio, explains how his company uses methane-eating bacteria (methanotrophs) to remove methane from agriculture and industrial sources while producing nitrogen-rich fertilizer. He details the hardware solutions, including aerated static piles for compost and trickle-bed reactors, designed to handle varying methane concentrations from dilute barn air to concentrated digester gas. Silverman discusses the business model, which prioritizes economic value for farmers through fertilizer savings over carbon credits, and addresses the challenge of scaling production via contract manufacturing to meet potential rapid adoption.
