Energetic insights into the thermochemical conversion process of CO2-mediated polyethylene terephthalate waste to para-xylene via tandem reactions

Key Points

• Para-xylene production was achieved from polyethylene terephthalate waste using CO2 in tandem reactions.
• Yield reached 80% within a defined reaction time frame, demonstrating a significant energy recovery.
• Analysis of CO2-mediated thermochemical conversion identified key intermediate processes for para-xylene synthesis.
• This approach offers insights for sustainable waste management, yet requires further validation in industrial settings.
