“…Recycling of polycondensation polymers, such as PC, via pure chemical routes can be summarised by the following technologies: hydrolysis (in acid, neutral or alkaline environment), glycolysis, hydroglycolysis, methanolysis and aminolysis [19][20][21][22][23]. These techniques have been recently reviewed [19].…”

The production of electric and electronic equipment (EEE), including personal computers, compact disks, TV sets, refrigerators, washing machines, toasters and many other daily-life items, is one of the fastest growing areas of manufacturing industry today. The rapid development in the EEE technology combined with a short life cycle and a variety of uses, at least for most of the products, poses a significant issue as far as their disposal is concerned. This has resulted in a continuous increase of Waste Electric and Electronic Equipment (WEEE) with some representative numbers: in the EU only, 9.5 million tones have been disposed in 2008 and this is expected to increase to 12.3 million tones in 2020 [1, 2]. While there is no generally accepted definition of electronic waste in most cases electronic waste consists of electronic products that were used for data processing, telecommunications, or entertainment in private households and businesses and are now considered obsolete, broken, or unrepairable (Figure 1). Despite its common classification as a waste, disposed electronics are a considerable category of secondary resource due to their significant suitability for direct reuse and material recycling. In view of the environmental problem involved in the management of WEEE, many countries and organizations have drafted national legislation to improve the reuse, recycling and other forms of recovery of such wastes so as to reduce disposal. The EU in an attempt to deal with the necessity of a meaningful recycling system and at the same time to preserve oil and fossil fuel resources has introduced 2002/96/EC directive [2], which demands 70-80% of WEEEs to be recovered in the form of energy and/or materials [2]. The directive aims at the minimization of the percentage of the solid wastes which will be landfilled or incinerated the full conversion of all waste streams (including plastics) through thermal or mechanic treatment by 2020.

The addition of small amounts of organoclays during the reprocessing of waste polycarbonates (WPCs) is a promising method for improving the properties of the recycled plastics. However, the clays can also induce the degradation of the polymer during the melt compounding and thus lower the properties of the final materials. This clay‐induced degradation of polycarbonate (PC) was examined in this study. A WPC, a virgin PC (VPC) (that served as a comparison), and two commercial montmorillonites, Cloisite 15A and Cloisite 30B, were melt compounded in a twin‐screw microextruder. The degradation of the polymer, which caused the formation of phenolic compounds and the reduction of the average molar mass, was monitored with UV spectroscopy, thermogravimetric (TG) analysis, and solution viscosimetry. The results reveal that the effect of the clays on the degradation depended on the amount of clay used and the chemical nature of the organic modification. When small amounts of the appropriate clay were used, the polymer degradation was minimized, and a net improvement of some properties of the recycled PC was achieved. © 2013 Wiley Periodicals, Inc.
