As someone working in carbon removal, this milestone is a big deal. Congrats to the Charm team on hitting this milestone!

I hosted an interview at AirMiners with Shaun, Charm's Chief Scientist, last June right after they received the purchase order from Stripe here: https://www.youtube.com/watch?v=Lk0k0ioXqkM

The conversation included 3 of the other Stripe finalists (Vesta, Climeworks, and CarbonCure, who just won the Carbon XPRIZE), plus Ryan from Stripe.

For those of you interested in more details, Charm has a blog post about their process here: https://charmindustrial.com/blog/2019/3/17/making-grass-flow...

Congrats again, and cheers to many more.

One thing I've been curious about -- I've got a few hundred acres of forest land, and I'm maintaining it in a natural state, but that still involves regular thinning/removal of biomass. I've wondered if there's a way to connect with someone like Charm (or any other company) to figure out how to supply biomass for their processes.

Maybe it's too small scale -- a few hundred acres doesn't produce that much timber. Or too distant. Or something. But I have no idea how to even start reaching out about it.

I'm looking at doing something similar (in Scotland) and am investigating the possibility of a small, on-site bio-char reactor.

Without a huge amount of research so far my high level plan is to convert waste bio-mass into biochar to sequester the carbon and then use the biochar as a fertiliser; for drainage etc. As long as it doesn't get burned then it should also work as a carbon sink.

I've considered this too, and honestly considered exiting the software industry to dive into this space. But I haven't really sat down and done the legwork yet.

I like it, curious to see what kind of options come up over the next few years. I don't have an answer for you though, asking around.

Here's a few answers from folks so far: - Check out Takachar, might be along these lines: https://www.takachar.com/ - Distance to transport the biomass matters a lot as well, so need to find something that makes sense closer to you than shipping biomass around the world

Interesting. Looks a long ways away (I'm in the Seattle/Pacific Northwest neck of the woods.) I wonder if the universities around here have any ideas though.
