This episode features Philip Ehrhorn, Co-Founder and CTO of The Great Bubble Barrier.

The Great Bubble Barrier uses bubbles to catch plastic over the full width and depth of rivers, preventing plastic from ending up in the ocean. Their system creates a bubble curtain diagonally across the river, pushing plastic to the surface and directing it into a catchment system. Great Bubble Barriers do not interfere with regular river activities, are safe for fish and other marine life and operate continuously. 

Philip and Michelle discuss why plastic pollution in our waterways is problematic, how Philip and his Co-Founders discovered that bubbles could help catch the plastic and the challenges of installing their technology on rivers around the world.
