This seminar provides comprehensive information about advanced plastic recycling methods. Both traditional and emerging recycling methods will be highlighted. Accumulation of plastic waste in the natural environment and the toxicology of plastics as well as their additives will be discussed. Furthermore, analytical methods and instrumentation to characterize recycled plastics, and the differences in virgin polymers and recycled polymers will be reviewed. Regulation and policy relevant to plastic waste management will also be discussed. Classroom lectures cover the basics of the advanced recycling process and provide case studies that yield inspiration and can be applied in various plastic products.


This course is appropriate for plastics recyclers, plastic resin suppliers, sales and applications engineers, new product development specialists, product marketing professionals, product designers and engineers, industrial designers and industrial engineers, mechanical engineers, materials purchasing managers, manufacturing personnel and technicians, plant managers, production supervisors, quality assurance and quality control personnel, and anyone involved in sustainability. It will also benefit chemical companies and waste managers.
