 At Yale University we work a lot around resource recovery and we use electrochemical and bio-electrochemical methods to achieve that. So where does that fit? If you think about it 30 years ago or so, anaerobic digestion started really taking off. And now biogas plans are everywhere in the world. So it's been a big success, but it was also a big mind shift. People started realizing that what goes in a digester is no longer a waste. In many cases it becomes a resource for energy. So in the future we'll be able to take this water and with very innovative techniques get the plastics surrounding your mobile phone out of it. So there's a lot of opportunities there for new researchers and new developers and new engineers to enter the water sector and really do new things but really look at it from a different perspective. We're no longer treating waste. We are taking a resource and we are turning into a product. And the product in the end, that's what counts.
