The company purchases sawdust and recycled wood. "The size of our plant is relatively small, which isn't a problem for procuring biomass. Over time, we can produce 15,000 tonnes of biocoal pellets or 30,000 tonnes per year of non-torrefied pellets," he emphasizes. Applications. There are many applications for biocoal besides replacing coal.
