Identification, Quantitation and Modelling of Pollutants Formed in the Chemical Recycling of Plastics Containing Brominated Flame Retardants and Antimony Trioxide

Project: HDR ProjectPhD

Project Details

Description

The growth in technology, population, and development in various countries amplifies the volume and size of waste generated from Electrical and electronic equipment (EEE). The brominated flame retardants (BFR) present in plastics derived from EEE have attracted significant attention, because of the toxicity of the chemicals to the environment and human health. The BFRs have been identified as persistent organic pollutants (POP) and have been banned from use replacing alternative novel BFRs. These novel BFRs share similar chemical characteristics as the banned BFR, possibly transforming into trace pollutants during the recycling process. Identifying and quantifying the pollutants formed during chemical recycling (pyrolysis) is crucial for comprehensive risk assessments. Understanding the type and level of pollutants generated can help implement appropriate safety measures and management practices to minimize exposure and potential health and environmental impacts. Most studies have primarily focused on examining recycling products (fuel and feedstock) and have overlooked the pollutants that may be formed during the recycling process of wastes containing BFRs. The researcher uses experimental and theoretical methodologies to identify and quantify trace pollutants formed in processes that recover bromine and antimony from plastics containing BFRs. The researcher further employs computational methods using Density functional theory to gain atomistic insight into the formation mechanism of targeted trace pollutants.
