Abstract

The expressive use of computer equipments such as personal computers and peripherals has greatly contributed to the formation of so-called waste electrical and electronic equipment (WEEEs). Due to the constant advancement in the development of more modern and functional equipments, devices of new generation become obsolete in a few years after use, producing post-consumer waste that cause environmental and waste management in large cities. The composition of waste is varied, corresponds to about 20% of the polymeric materials which are used as the structural part or in the setting of electronic circuits. The copolymer acrylonitrile-butadiene-styrene (ABS) and the high impact polystyrene (HIPS) are the most abundant. This research project was aimed at studying the recycling of thermoplastic polymers used in the manufacture of computer equipment through the preparation of compatibilized blends from polymeric waste with the virgin HIPS. The use of virgin HIPS aims to improve the properties of the waste that is depreciated by degradation processes without affecting the basic composition of the waste, providing a viable alternative in terms of cost and performance of these recycled materials. Besides the economic aspect, WEEEs recycling is a way to minimize the environmental and management problems caused by the irregular disposal of solid waste. (AU)
