Trash to Treasure: Co-Pyrolysis of PET Plastic and Hibiscus Rosa-Sinensis for Sustainable Syngas Production

EasyChair Preprint 14397

Abstract

The growing plastic waste, particularly Polyethylene Terephthalate (PET), presents a signif-icant environmental challenge. Co-pyrolysis, a thermochemical method that breaks down mixed feedstocks in the absence of oxygen, offers a potential solution for converting plastic waste into useful resources. This study investigates the co-pyrolysis process by heating PET plastic in combination with Hibiscus Rosa-Sinensis (HRS), an easily accessible biomass source, to determine its potential for sustainable biofuel production. The results demonstrate that a mixture of 50% PET and 50% HRS produces higher yields of Carbon Monoxide (CO), Carbon Dioxide (CO₂), Methane (CH₄), and Hydrogen (H₂) compared to the pyrolysis of each material individually. At a temperature of 432°C, the mixture achieved peak productions of CO at 293 ppm, CO₂ at 400 ppm, CH₄ at 150 ppm, and H₂ at 120 ppm. These findings indicate a strong synergy between PET and HRS, en-hancing the efficiency of producing desirable gases for more efficient syngas production. This research contributes to the development of more environmentally friendly and eco-nomical syngas production technologies, supporting global efforts in climate change mitiga-tion and the transition towards a low-carbon economy.
