BioPellet, LLC's BioBricks have a uniform rectangular shape which makes it easier to tightly pack a stove with the greatest amount of BioBricks. Because these "BioBricks" can be tightly packed, the fire burns longer and more uniform. A ton of BioBricks, when burned, will give as much heat as a cord of seasoned firewood. At BioPellet, LLC our BioBricks are free of the dust, dirt, bugs, vermin, and the mess that is commonly associated with burning cordwood. Request Quote & Orders
