The economics of just carbon credits (~$1,500) wouldn't seem to justify pyrolysis equipment purchase like this, but if you can sell the biochar? Definitely makes it important to use the heat for something profitable more important too.
Let's see, about 6 metric tons of biochar from 100 cubic yards of wood chips could be sold for about 20 cents per kg according to WalMart. So that's about another thousand bucks or so.
About 200 hours to pyrolysize that 100 yds. Not going to get rich. #biochar
