Abstract

This study employed a process targeting technique to evaluate thermodynamic, environmental and economic feasibility of the synthesis of methanol and acetic acid (AA) from waste tyres and forestry waste (pinewood waste). The results revealed that the synthesis of methanol from waste tyres and pine wood produced CO2 and was constrained by the change in enthalpy whereas the synthesis of AA was constrained by the change in Gibbs energy and did not produce CO2. Additionally, the carbon efficiency, atom economy and economic gross potential (EGP) for the synthesis of methanol from waste tyres and pinewood waste co-feed were determined to be 69.17%, 62% and $ 0.245 million per year, respectively. In contrast, these metrics for AA synthesis were 100%, 100% and $ 1.878 million per year, respectively. It was further determined that 1 mole of methanol can be co-produced with approximately 1.19 mole of AA from waste tyres, while 2.719 mole of AA can be co-produced with 1 mole of methanol from pinewood waste without any CO2 emissions.
