I guess that presupposes anyone would be dumb enough to burn anything
green in a woodstove regardless of its kind. Be that as it may, a
non-catalytic would be the better performer; well, at least up to the
point the chimney catches on fire. ;-)

EPA compliant woodstoves have a secondary combustion system that
re-burns the combustion gases prior to their release. This is
accomplished with either a catalyst or what are called secondary burn
tubes located immediately below the top baffle (non-catalytic). The
efficiency of these stoves is nearly twice that of a conventional
airtight design (i.e., 75 to 80 per cent) and the amount of
particulate produced is extremely low -- typically in the order of 3
grams per hour.
