Operating parameters such as percentage composition, process temperature, and particle size affects the outcome of the co-pyrolysis of coconut husk and plastic laminates. Highest yield of 31.17% occurred at 600oC, 5cm particle size and 32% of coconut husk. The corresponding energy value was 1.89688 MJ. On the other hand, the highest HHV of 33.881 MJ/Kg occurred at 700oC, 3cm particle size and 32% coconut husk. Using RSM response optimizer, the optimum yield of 32.5% occurs at a temperature of 700oC, 5cm particle size and 50.42% coconut husk. For HHV, the temperature of 700oC, 5.0 cm particle size and 32% coconut husk will have a maximum value of 34.1142 MJ/Kg. Conversely, the energy value will have a maximum value of 1.9125 MJ. The ANOVA values for yield, HHV and energy value were (F = 4.90, P = 0.0475), (F = 556.62, P = <0.0001) and (F = 12.93, P = 0.0058), respectively indicating that the models were significant. According to the F-values, the linear term of coconut husk (C) and temperature (A), had a more significant influence on the pyrolytic oil yield, HHV and energy values than did particle size (B).
