The current study's major issue is the transition from trash to value-added products. Eggshell waste is one of the most typical byproducts of food manufacturing. Eggshell is a calcium-rich material that can be used as an economical supply of Ca2+ for the construction of Ca-BTC MOFs. The catalytic impact of an eggshell-based metal-organic framework was explored in the Knoevenagel condensation reaction. To find the best condensation reaction setup, we looked at the effects of different solvents, such as ethanol, ethyl acetate, and toluene, as well as the effects of different temperatures, such as 30-80 degrees C, and different dosages of Calcium-BTC. Ca-BTC's recoverability, reusability, and durability were also confirmed under optimal conditions. Ca-BTC's catalytic performance in the Knoevenagel reaction for condensing various aldehydes with malononitrile derivatives yielded benzylidenemalononitrile with yields up to 99% in a relatively short period under ecologically friendly settings.
