Abstract: Epoxidized castor oil (ECO) has synthesized with glacial acetic acid and hydrogen peroxide in the presence of a catalyst. Here hydrogen peroxide (H2O2) acts as an oxygen donor and glacial acetic acid acts as an active oxygen carrier. Epoxidized oils have respectable oxirane oxygen content and highly reactive oxirane rings. The formation of the oxirane ring was confirmed by Fourier Transform Infrared Spectroscopy (FTIR) analysis and Nuclear Magnetic Resonance (NMR) studies. Vegetable oil-based epoxies are sustainable, renewable and biodegradable. These Epoxidized oils can replace petroleum derived materials in numerous industrial applications

Abstract: Plastic components from waste mobile phones were sorted and characterized using visual, spectroscopic and thermal methods. The mechanical properties of the recovered plastics were investigated by comparing with commercially used reference materials. The results revealed the practical feasibility of these recovered plastics to make new products through mechanical recycling. The samples were also tested for brominated flame retardants (BFRs) using gas chromatography-mass spectrometry (GC/MS) technique and the results indicated the absence of BFR in recovered plastics, hence these can be processed without any risk of BFR toxicity.
