Development and evaluation of an integrated waste to energy system based on polyethylene plastic wastes pyrolysis for production of hydrogen fuel and other useful commodities

•Plastic wastes are accumulating each year without an effective solution.•Plastics are energy-dense material that could be used to produce synthetic fuels.•A multigeneration system is developed in this article to utilize plastic wastes.•Parametric studies are performed to identify optimum operating conditions.•The developed system produces five useful outputs.
