For further discussion…
What do we need to know and understand about this potential approach to collection and destruction of refrigerants?
What are the “business as usual” approaches to collecting outdated refrigerants?
Is there a compelling reason for this approach? Where does it fit in the continuum of refrigerant collection?
Are there processes - chemical or otherwise - that can turn collected refrigerants into something useful?

Hi Stet
This seems like great forum content if we wanted to cover refrigerants at one of the upcoming sessions.@Kristof Irwin@Paul Herron@Brian Johnson looping you in for reference if we can find a place for this on an upcoming agenda.

Thanks for this Stet.
I need to understand the business case, and how the carbon credit is
supposed to figure in - who owns the credit and how is it monetized. I’m
also curious to know the GHG emissions associated with capture and
“destruction” as well as the resulting molecules from that process - are
we exchanging GHGs for PFASs?
While I am happy to know someone may have figured out a process to keep these
gases out of the atmosphere, unless there is a compelling reason
(either regulatory or economic) to adopt this practice instead of
business as usual, this may simply be an academic exercise.

Hello Illustrious MEP2040’ers
I was meeting last week with a company that has created a business around
recovering the nastiest of refrigerants, destroying them, and providing
a carbon credit to fund the process. They were introduced to me by
Lindsay Baker, ILFI, because we’re good friends, grad school buddies,
and obsess all things decarb. Anyway, they are looking for a larger
audience to get out folks aware of that potential pathway for
refrigerants, instead of shipping them half way around the world to
eventually leak out. They’d be interested in offering a webinar
internally to MEP2040 folks if you think it would be appropriate. I
know we were trying to be manufacturer/supplier agnostic, etc…. so I
wasn’t sure if that was too commercial for the group. If you think it
would be worth and introduction and conversation, their contact info is
below:Ray Rieling rrieling@tradewater.us
