This book is dedicated to research in the densification processes of wood waste and its mathematical description for uniaxial densification into compact solid Biofuels - briquettes. The publication shows the experimental strategy to determine the effects of individual parameters and specifies their impact on the resulting density of the briquettes. The book also provides the results of experiments on differing types of wood biomass.
