Electricity generation from co-pyrolysis gas of fresh palm fruit bunches and medical waste plastic bottles for sustainable energy applications

Co-pyrolysis gas produced from the co-pyrolysis of fresh palm fruit bunches and medical waste plastic bottles using a batch pyrolyzer integrated with a downdraft gasifier was evaluated for sustainable electricity generation. Increasing the plastic fraction enhanced the gas heating value (41.43–55.53 MJ/Nm 3 ) but decreased gas yield from 22.7% to 9.0%. Electrical efficiency was calculated based on the ratio of output power to syngas energy content, achieving 8.96–9.01%. Engine tests showed a reduction in CO emissions (30,149–17,419 ppm) and comparable NO x levels to gasoline combustion. These results demonstrate the co-pyrolysis gas's potential as a renewable fuel for decentralized power.
