New England Pellet may have bought or licensed the Greene Team name however the Greene Team web site still lists Pennsylvania:

So probably a license agreement with NE Pellet.
We burned Greene Team for 2 winters, a few years ago. Those came from Penn and were very good. When Lowe's jacked the price way above the price for the Green Supreme blend (New England Pellet), I made the switch.
I do keep records of dates the P-43 was cleaned and cumulative # of bags burned. With Green Supreme my average is 18 bags between cleanings with a range of 15 to 22. I clean when the ash pan is full or close to it which is usually 18 bags. Works out to about once every 2 weeks.
