Nov 01, 2019  Briquetting is a densification process in which loose biomass are compacted under pressure so that the density of biomass residues could be increased up to about 1000–1200 kg/m 3 and the volume be increased by 8–10 times of the loose biomass [13], [14]. Briquetting process can be categorized base on binder usage or not.
