Abstract
A method is disclosed for producing a mechanically stable, energy dense and water-resistant biomass product. By utilizing a unique two-step heating process in combination with mechanical compression, the resulting biomass product retains its physical shape and strength after immersion in ambient water for many hours. The treatment is effective for a variety of cellulosic biomass materials including forest slash wood.
