Abstract

The paper will focus for technical plastics, which are comprised of high performing segment of synthetic plastics with excellent thermal and mechanical properties in comparison to commodity plastics. Although commodity plastics contribute to 80% of the total plastic consumed worldwide, technical plastics had seen immense development in past decades mainly due to their superior performance and their market value is predicted to reach above $90 billion by 2020. While technical plastics are generally expensive than commodity plastics, they exhibit superior mechanical strength, high heat resistance, toughness, rigidity and ease to process. Due to these exceptional characteristics, they are extensively used in electrical and electronics, consumer goods and transportation applications. This high growth and extensive usage of technical plastics had led to huge amount of waste generation especially from end-of-life waste electrical and electronic equipment (WEEE) which mainly composed of acrylonitrile butadiene styrene (ABS) and polycarbonate (PC) plastics. Generally, these materials from the plastic waste show good properties and can be recycled. The recycling of WEEE possess certain challenges such as fraction of WEEE are composed of over 10 different types of polymers, presence of different types of fillers, colorants, fire retardants and finally oxidative degradation of butadiene rubber phase in electronics products during service time which deteriorate mechanical performance. However, using methods such as melt blending had shown to improve the mechanical properties of recycled material and enabling the possibility of recycled technical plastic to make their way back into more consumer and industrial products.
