Climeworks is doing some work with atmospheric capture and sequestration in basalt via underground water injection (I believe they site with hydroelectric plants which gives them the reinjection well infrastructure mostly for free).

You can do the same thing by grinding basalt and spreading it on fields, which... given that I live on a pile of basalt, might be useful eventually. I keep collecting the stuff to make a greenhouse with, though.

It may be better than leaving it in the air, but given all the other biological activity of plastic, I'd really rather we not use the stuff in the first place at this point.
