Received polycarbonate wastes from used optical discs chemically recycled to
Bisphenol- A by using water as the solvent, Cloisite 30B nanoclay and sodium
hydroxide as the support and catalyst, respectively at convenient, green and eco-
friendly conditions. The performances of the support in Bisphenol- A recovery
yield were examined in comparison with the unsupported as well as nano-SiO2
and nano-TiO2 supported reactions. The optimum condition by having 90%
recovery yield was found at 90 min when the reaction performed at equal waste/
solvent ratio, catalyst 1% and nanoclay 2%
