I received my BSc in industrial chemistry and MSc in environmental science from the King Fahad University of Petroleum and Minerals (KFUPM), Saudi Arabia, in 1995 and 2002. Then, I worked as a research scientist at the KFUPM Research Institute on material characterization.

In 1996, I worked as a chemist in Gulf Ferro Alloy research and development division, and then I became the head of the division. In 2002 I joined SABIC Technology Center in Jubail, Saudi Arabia, as Sr.Scientist in the metal analytical lab working on material characterization and identification. After six years, I moved to the SABIC Corporate and Research center at KAUST, working under the catalyst department involved in several catalyst studies and development projects.

Short description about presentation:

Plastics have occupied an essential part of life. Their usage pattern in daily life in furniture, housewares, mechanical, engineering, aviation, floor sheet, lamination, biomedical are only a few examples. However, inappropriate disposal and utilization of recycled plastic products are significant sources of environmental pollution. In addition, packaging material has many toxic heavy metals such as cadmium, chromium, lead, and mercury. Thus, it contaminates the environment and causes public health problems.

Nevertheless, until today, limited data are available on detailed polymer composition and elemental quantities of municipal plastic waste, which is the essential information for mixed plastic waste recycling to produce a stream of valuable chemicals. Here, we use the virgin polymers (PE, PP, PS, LDPE, HDPE) that are the major components of the MPW to prepare the uniformly mixed samples. The virgin polymers' FTIR and DSC spectrum features are used to prepare the standard calibration curves (SCC), which are then used to quantify the MPW. In this work, we also performed the elemental composition analysis of the MPW by XRF and ICP, including C, H, N, S, O.
