Co-ordinated by Professor Stuart Harrad at the University of Birmingham, the overall vision of INTERWASTE is to develop scientific understanding of issues related to environmental contamination with toxic and/or hazardous organic chemicals (specifically flame retardants (FRs) and pharmaceutical and personal care products (PPCPs)) arising from their presence in the waste stream. The central hypothesis is that the presence of such chemicals in the waste stream represents a substantial environmental hazard. INTERWASTE will test this hypothesis by evaluating the extent of environmental contamination attributable to emissions from selected components of the waste stream, and further will evaluate the efficacy of actions to minimise such environmental contamination. This will be achieved by a co-ordinated programme of collaboration between 27 leading research centres from Europe, Africa, Asia, Australasia, North and South America. The programme is centred around 87 research secondments totalling 224 researcher months between world-leading research groups both within and outside the EU. QAEHS will host 11 scientists for a total of 25 months in the coming 2 years to jointly further the aims of the INTERWASTE program.
