| Summary: | There are plentiful experimental studies on biomass as heterogeneous catalyst and its reasonable cost, it can be a
potential catalyst feedstock for biodiesel production. This study presents the life cycle assessment (LCA) of waste
cooking oil biodiesel production catalyzed by waste chicken eggshell derived CaO catalyst to validate the suitability of waste chicken eggshell as a green catalyst in biodiesel field. To the best of our knowledge, LCA was first
performed for the heterogeneous catalyst, CaO preparation as a subsystem in a biodiesel production. Comparative studies were performed to evaluate the difference of environmental impacts contributed by waste cooking
oil, WCO biodiesel production catalyzed by waste chicken eggshell derived CaO with the two different production processes via Jatropha oil as the oil feedstock and potassium hydroxide, KOH as the homogeneous
catalyst. Utilization of WCO as the oil feedstock for biodiesel production has lesser environment impact than the
Jatropha oil as the WCO biodiesel production does not involve agriculture phase. Likewise, utilization of waste
chicken eggshell derived CaO catalyst (heterogeneous catalyst) has less contribution on the overall impact
categories than KOH (homogeneous alkali-based catalyst) as the production of KOH required addition of
chemical and additives, plus complex purification and neutralization processes are required during the production phase. The overall impact results clearly indicated the best environmental performance of waste chicken
eggshell derived CaO of 1.17 Pt was over the traditional KOH catalyst and implementation of Jatropha oil but
also identified some bottlenecks that should be addressed for more sustainable solutions. |
