Brian Sundberg, dairy nutritionist and cofounder of Progressive Dairy Solutions, joined the World Without Cows Podcast to discuss cows’ ability to upcycle food waste into foods we need.

Progressive Dairy Solutions is a nutrition and management consulting firm that works with dairy farms across the U.S. and internationally, formulating diets for 1.2 million cows and overseeing $4.4 billion in annual feed investments, Brian explains. What’s truly remarkable, Brian says, is what those cows are eating — and why it matters for the planet.
