Abstract In this study, we prepared a green heat stabilizer tannic acid–calcium oxide (TA–CaO) adduct in a green method and its efficacy was studied in a bio‐based polyvinyl chloride‐thermoplastic starch polymer matrix. The composite was prepared in a green pathway by melt mixing. CaO in the prepared complex also acted as a reinforcing filler in the composite. The addition of TA–CaO adduct in place of lead carbonate improved all the physical and chemical properties of the composite. The tensile strength and flexural strength improved to 102% and 127%, respectively, in comparison with similar percentage of lead carbonate and TA–CaO adduct. The composite with 15 phr loading of TA–CaO showed improved properties compared with other TA–CaO loaded composites.
