- The dynamic porosity concept was applied to the drying of 14 samples of sawdust at 50 °C, 60 % relative humidity and 87 kPa. Determination of the critical extent of drying, where the transition from constant-rate to decreasing-rate kinetic regimes occurs, indicates that Lecythis ampla sawdust is the material that allows water diffusion with the highest kinetic and energy efficiency, amongst the set of residual biomasses.
