Characteristics of briquettes made from various biomass resources (staghorn sumac wood, vineyard and apple tree pruning biomass, pine cones, corn stalk and corn cobs) were investigated in the present paper. The moisture content of raw materials was first determined, before compacting them in a hydraulic briquetting machine. Briquettes with diameter of 40mm and various lengths were obtained. Five replicates of each briquette type were selected for the determination of density, compression strength and calorific value. The results were compared to those of beech and pine briquettes obtained under similar conditions. Based on the experimental results, mathematical correlations between density and compression strength and density and calorific value were investigated.
