In terms of sustainability, in the past, we were concerned about wood, but we didn't have the engineering we have now.
Let me give you an example of what we are doing at Boisaco. Boisaco also has a poplar processing plant. We do not want to waste hardwood. When we harvest poplar, there is also some birch. So we wanted to find a way not to waste the birch. Since this year, we have been making birch pellets. That is proof that anything can be done. We always try to be at the cutting edge.
