Bill Gates has joined a slew of billionaires investing in an Australian climate technology startup that has plans to disrupt the methane-emitting animal agriculture industry with a lab-grown feed additive. 

Breakthrough Energy Ventures LLC, led by the Microsoft Corp. founder, and Andrew Forrest’s Harvest Road Group took part in a $12 million Phase 2 seed funding round for Rumin8 Pty, according to a statement Monday. The Perth-based firm is developing a supplement for livestock made from synthetically-replicated bromoform, the active ingredient found in a red seaweed.
