Welcome to the SAFER Research Project

Welcome to the website for the “Screening of the Irish Waste Stream for Persistent Organic Chemicals (SAFER)”

This research project is a collaborative effort between the University of Birmingham’s School of Geography, Earth, and Environmental Sciences, and NUIG’s School of Physics , and is funded by the Environmental Protection Agency of Ireland. This Project is a continuation of a previous EPA-funded research project carried out by the same research team. The preceding “WAFER” project (Identification and Treatment Options for Waste Streams of Certain Bromine Containing Flame Retardants), involved the screening and assessing of POP-BFRs in a variety of waste plastic materials in order to determine the resulting effects on the circular economy. Among the major findings of WAFER was the discovery that other, non-regulated brominated flame retardants (BFRs) were present at high concentrations alongside those which are listed under the Stockholm Convention on Persistent Organic Pollutants. This represents a barrier to the effective screening of waste plastics containing POP-BFRs as the presence of other “novel” BFRs (NBFRs) can interfere with screening processes.

Thus it is important to understand the relative contributions of the various BFRs (regulated and non-regulated) in order to optimise screening processes designed to remove hazardous chemicals from circulation. The SAFER project aims to fill this knowledge-gap by building on the findings of the WAFER project (for full details, see EPA Report #272) to determine the levels of NBFRs in waste plastics, the shifts in concentrations of POP-BFRs resulting from their regulatory restrictions, and the  implications this may have on any hazardous chemical screening processes.

SAFER will additionally build upon another project which documented the presence of certain hazardous chemicals in landfill leachate from sites around Ireland. The “FUEL” project (Furthering Understand of Emissions from Landfilled Waste Containing POP-BFRs and PFOS) discovered that large concentrations of BFRs as well as perfluoroalkyl substances (PFASs) were present in landfill leachate collected from sites around Ireland. This shows that waste containing high concentrations of these chemicals were (and in some cases still are) being disposed of in landfills and are thus eluting into leachate and potentially contaminating the environments surrounding these sites. SAFER aims to determine which waste destined for landfilling is treated with these chemicals, how much of this waste ended up at said sites, what degree of environmental contamination occurred because of their presence, and what effects this may have on leachate treatment and groundwater quality.
