Abstract
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%.
