This research focuses on pertinent parameters to improve the performance of four plastic recycling plants. The method
used in this work is the overall equipment effectiveness (OEE) analysis. After assessing data collected and comparing calculated
values with global accepted standards, there was need to optimize the OEE value of 74.40% for plant P48mold which was below
the universally accepted value of 85% and for plant P72mold which is exactly 85%. Optimization toolbox is used to select values
for cycle time ranging between 0.75min and 0.73min to improve the calculated value of 74.40% for plant P48mold and 85% for
plant P72mold. Optimizing the OEE values significantly increases production by making the operation cost-effective. The OEE
value was obtained by multiplying the three factors of availability rate, performance rate and quality rate and optimized values of
87% for P48 mould and 115% for P72 mould were obtained respectively.
