Overview

• Savor Foods has begun supplying pilot batches of its gas-derived butter to restaurants and bakeries as it works toward a retail debut around 2027.
• The startup captures carbon dioxide from air and hydrogen from water, thermochemically converting them into fat molecules that mimic dairy butter.
• Bill Gates and other investors have backed Savor, praising its potential to cut greenhouse-gas emissions by an estimated 60 percent compared to conventional butter.
• The American Butter Association has petitioned the FDA to enforce longstanding standards of identity for butter, challenging Savor’s product labeling.
• Unverified social-media posts alleging FDA greenlighting without safety data and human-waste origins have circulated widely but lack confirmation in mainstream outlets.
