This document provides guidance on the best practices and technical solutions that manufacturers of electrical and electronic equipment (EEE) can consider during the design phase, to enable consistent and effective recycling of styrenics and polyolefins plastics composing the equipment, during the Waste of Electrical and Electronic Equipment (WEEE) management. NOTE This Technical Specification is intended to cover electrical and electronic equipment as listed in Annex I and Annex III of Directive 2012/19/EU [6]. This document deals specifically with the following types of styrenics and polyolefins, used for parts and components of EEE: Acrylonitrile-Butadiene-Styrene (ABS); Polystyrene (PS); Polypropylene (PP). NOTE The principles laid down in this document can be potentially applied to thermoplastics other than ABS, PP and PS.
