Challenges in Treatment of Plastics from Electronic Waste

RoHS Substances in Mixed Plastics from Waste Electrical and Electronic Equipment

With the contribution of the LIFE financial instrument of the European Community. We are grateful to the WEEE Forum and the European Community for having supported this project. A special thank goes to all those members of the WEEE Forum who provided laboratory samples. Finally, we would like to express our gratitude to the Swiss WEEE system operators SENS and SWICO, who initiated this project ...

The characteristics of plastics - rich waste streams FROM END - OF - LIFE ELECTRICAL AND ELECTRONIC EQUIPMENT

The results from numerous studies on the plastics fractions obtained from waste electrical and electronic equipment have been analysed and an assessment made of their suitability for recycling or other forms of recovery. In view of the challenge to ensure the suitability for mechanical recycling by removal of various substances, it is concluded that it is prudent to explore the benefits or othe...

Electrical and Electronic Plastics Waste Co-Combustion with Municipal Solid Waste for Energy Recovery

Study on chlorine removal from mixture of waste plastics.

The recycling of waste plastics that include plastics that contain chlorine, such as polyvinyl chloride, is difficult because the chlorine leads to the corrosion of equipment. Then, the dechlorination method of waste plastics containing chlorine (CCWP) that consists of a series of melt process and hot water process was examined. CCWP was put into the melt process with coal tar (HOB) and convert...

Voc Emissions from Waste Plastics during Melting Processes

Hazardous compounds emitted during the plastic melting process were analyzed to indicate potential air pollution issues associated with recycle plants for waste plastics. These hazardous compounds might be not only from polymer degradation but also from additives and print ink. To confirm what are emitted from them, melting experiments were conducted (150, 200 and 250°C, in air or N2) and volat...
