Sigh. From another place. Isn't this the same petcoke issue that JBII must deal with?:

By the way, according to Agilyx, their big system can process 32 tons of plastic a day. It also creates 9% carbon waste per day.

How much is it going to cost Agilyx to get rid of that 2.9 tons of waste carbon every day of operation?
