For this study, briquettes were obtained from the residues released in large quantities after tomato harvest. The effects of
particle size and compaction pressure on solid biofuel properties were investigated. A redesigned hydraulic press was used
for this. With this machine, briquettes with the compression pressure adjustable in the range of 0-240 MPa and a mold
diameter of 50 mm were obtained. The briquettes obtained are at six different compression pressures 25, 50, 75, 100, 125
and 150 MPa, two particle sizes 2–5 mm, 7–10 mm and 8–10% moisture content. Shatter and tumbler tests, briquette
firmness, briquette density, capacity and specific energy consumption values were determined for the briquettes’ physical
strength and machine properties. Briquette densities on wet basis varied between 788.04 and 1333.28 kg.m− 3. The results
obtained were analysed using statistical methods, including PCA and ANOVA. The volume weights of the briquettes at
different compression pressures were significant (p < 0.01) at a compression pressure of 150 MPa and a particle size of
7–10 mm. The highest average values were obtained for briquette density 1330.40 kg.m− 3, hardness 11617.51 N, tumbler
test 98.95% and breakage test 99.22%. It was determined that the highest capacity value 5.16 kg.h− 1 obtained in the
study reached 125 MPa compression pressure and 2–5 mm particle size. The highest specific energy consumption value
of 0.70 kWh.kg− 1 was obtained at 150 MPa compression pressure and 7–10 mm particle size. The study’s results have
determined that the compression pressure and particle size affect the properties of solid biofuels of briquettes obtained
from tomato residues. Briquettes with a pressure value of 150 MPa and a 2–5 mm particle size were the strongest in solid
biofuel production.
