In the transition from fossil-based to renewable energy
sources, the use of fuel pellets created from leftover biomass
from the industry for energy production has gained popu-
The pelleting process is an established technology, where
the main optimization focus in recent studies is based on
the material used in the process. The focus in this study
is the entire pelleting process, with an investigation of both
material parameters and process parameters.
Design Of Experiment was used to determine the experi-
mental variations to test at each run, from which an op-
timization equation with: total energy consumption of the
process, maximum pressure used in the process and dura-
bility of the produced pellets as response variables.
A statistical analysis using signicance was conducted on
the design variables to determine the signicance of the ef-
fect they have on the responses resulting in reducing the full
model of terms.
Optimized settings for the pelleting process at the four dif-
ferent durability limits of EU regulations are present in the
results along with a discussion and conclusion of the results.
