‘Sustainable Development Research Forum’ July 19th 2007

PRIMARY DIRECTIVE:3rd-stream activities

i.e. applied R&D / consultancy which bring in •Profits•Esteem for the University•Links for teaching and research•Interactions with wider community

‘Standard’ Teaching


(Around £1,500,000 in last 6 years; self-funding Group)

•Automotive waste

•Developing new products from waste (biomass, carpets, glass, plastic, wood, textiles)

•Development of XRF spectrometer for contamination detection

•Kerbside recycling scheme development

•Waste diversion development – Green Cones

•Household incentives // Behaviour change

•Truly SD… Values Based Indicators (project level): EU

3rd- Stream Activities………….with R&D aspects:

Automotive Waste: new products

Recover more metals?Use as a fuel?

…develop a thermal process….PYROLYSIS

…only if lead contamination is not too high….

ASH or CHAR


XRF spectrometer – Heavy Metal Contamination

Excellent for on-site investigation!

Or for heterogeneous samples!

Or for multiple samples for statistical analysis!
