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
