In the biomass briquettes that have 50% biomass, they started to bend at a mean value
of 2124.43 grams. Those with 37.5% biomass started to bend at 2291.1 grams. One of the test
samples cracked due to the orientation of the briquette and the surface of the briquette was
not leveled during the pressing. Most of the briquettes produced had a thin center and thick
sides. The briquettes with 0% biomass did not have any significant changes when a weight of
2291.1 grams was added.
The briquettes with 50% and 37.5% biomass acted like cardboard. Thus, when weight
was added to them, they just bent or were pressed even further. The briquettes with 0%
biomass were hard but porous and required greater weight to crack them.
