Directional methanolysis of kitchen waste for the co-production of methyl levulinate and fatty acid methyl esters: Catalytic strategy and machine learning modeling

•ML and FAMEs were synthesized synchronously from real kitchen waste.•C/Si composite and Zr/USY catalyze the formation of esters synergistically.•This strategy has applicability to kitchen waste with different constituents.•Machine learning models were built for prediction and feature importance analysis.
