To enhance the consumption of renewable energy and address the increasing volume of household
plastic waste and used cooking oil, as well as sawdust waste from the furniture industry, utilizing these
three materials into an alternative solid fuel in the form of briquettes is highly needed. This study aimed
to determine the effect of the mixture ratio of plastic waste (PW), sawdust waste (SW), and used cooking
oil on the gross calorific value and volatile matter content of the briquettes to evaluate their potential for
industrial use in Indonesia, aiming for a minimum calorific value of 5,001 kcal/kg. The research method
involved sun-drying the sawdust and plastic waste, shredding the plastic waste, and mixing them with
sawdust and used cooking oil at three PW:SW ratio variations (45%:55%, 50%:50%, and 55%:45%). The mixtures were then molded using an automatic briquette molding machine at a controlled temperature
of 152°C. The test results using a bomb calorimeter showed that the gross calorific value increased from
6,244 to 6,683 kcal/kg, while testing with a volatile matter tester showed an increase in volatile content
from 79.10% to 80.80% as the proportion of plastic waste increased. In conclusion, an increased plastic
waste ratio enhances both the calorific value and the volatile matter content of the plastic waste–
sawdust–used cooking oil composite briquettes.
