CES is a new, ecologically safe and inexpensive green catalyst obtained from renewable resources. Graphical Abstract A convenient, eco-friendly and economic method for Knoevenagel condensation of aromatic aldehydes with active methylene compounds using CES as an efficient natural catalyst in aqueous medium has been reported here. CES is a new, ecologically safe, inexpensive and green catalyst obtained from waste eggshells.
