How so? Carbon disulfide is rather nasty, but it's straightforward to recover most of it. TLV is 10 ppm, while the effluent air from Teepak is 100 ppm [0], meaning you could spend hours a day with just over a 10:1 dilution of the factory exhaust. And there are lots of efforts to get those emissions way lower.

If it means less microplastics, I'm all for it.
