This paper presents the investigation results of specific piston pressure (45 to 113 MPa) and the addition of a calcium lignosulphonate binder effect on the compaction parameters of white birch sawdust. The experiments were performed with the use of the ZWICK Z020/TN2S universal strength tester and a closed compression assembly. An increase in pressure led to an increase in material density in the compression chamber and agglomerate density (by 18.5% on average), and it more than doubled the mechanical strength of the agglomerate. Higher compaction pressure increased the demand for compaction energy by 108% on average. The addition of binder increased the agglomerate density and the mechanical strength of agglomerate by 250% on average.
