@Knickknack @realChem I graduated in chemical engineering back in '83 and found myself in wastewater treatment consulting. I gradually transitioned to industrial wastewater and then hazardous waste remediation. It was a good gig! Retired in 2001, so it has probably all changed quite a bit. Good luck to you!
@Knickknack I volunteer with openaircollective.cc - focused on carbon dioxide removal, speaking of emerging sectors. It is all volunteer, and a good way to follow the burgeoning climate change mitigation realm. I’m using a lot of what I learned over the years in business to develop a wiki there: https://openairforum.org Come by some time!
