Recyclability Study of CaO Catalyst Derived from Chicken Manure in Transesterification of Waste Cooking Oil into Biodiesel

Abstract

The use of waste cooking oil (WCO) as a feedstock for biodiesel production addresses the dual challenges of waste management and renewable energy generation. However, the limitations of homogeneous catalysts, such as high costs and environmental concerns, necessitate the exploration of heterogeneous catalysts. This study investigates the recyclability and efficiency of calcium oxide (CaO) derived from chicken manure in the transesterification of WCO. The research aims to evaluate the catalytic performance across multiple cycles and its impact on biodiesel yield.
