Summary: Construction waste is a significant environmental problem due to its landfilling/incineration treatment, which increases the risk of releasing microplastics, leachates, air pollutants, and toxic gases. However, there is still a lack of sustainable disposal methods for building plastic waste. This study proposes a cleaner and safer disposal platform for building insulator waste (BIW) by using CO2 as a detoxifying agent. Through catalytic pyrolysis, toxic chemicals in BIW can be transformed into syngas (H2/CO), and CO2 facilitates the conversion of toxic compounds into CO, reducing their hazardous effects. This research confirms the technical feasibility of catalytic pyrolysis under CO2 as a promising disposal method for BIW.
