MIRPSTitle of the Sub-Project: Mid infrared Spectroscopy for Black Plastic Sorting - MIRPS Description: The EU end-of-life vehicle directive prescribes a minimum recycling rate for cars of 95% (weight) in 2015. To realise this also the plastic parts of vehicles have to be recycled. Sorting of different kinds of black plastics is crucial for efficient recycling enabling production of quality products from the recyclate. This can be done very efficiently by mid infrared (MIR) spectroscopy. Unfortunately, today's available MIR devices have long measurement times and are not designed to operate under harsh environmental conditions. This results in low throughput rates and high maintenance costs. Since MIR measurements are highly surface sensitive, the necessity for pretreatment of the samples has to be investigated to achieve reproducible results. The aim of the MIRPS project will be the development of a black plastic identification system based on MIR spectroscopic reflection measurements. In this project new MIR - spectrometer - technology developed by UAR is advanced to perform the sorting task. The project partners will further develop this device to realise very short identification times and thus high throughput rates. Methods reducing the influence of ambient water vapour and for the detection of flame retardants used in plastics will be investigated and implemented. Illumination and light collecting optics enabling measurements under harsh conditions will be developed. Investigation of different pretreatment methods for removing surface coatings (e.g. lacquer) will lead to optimized measurement conditions. MIRPS fulfills the Regins goals as partners from Upper Austrian and Baden-Württemberg will join their experience and cooperate in a number of fields. Moreover, a long term R&D partnership is planned with the intention of realising new, so far infeasible, industrial applications in different fields based on the new IR technology. Main points of cooperation will be chemo-metric data treatment and evaluation, infrared optics and pretreatment methods. The project results will be published at press conferences, in relevant journals, public newspapers, on the web pages of the subproject partners and in adequate seminars at national and international conferences and fairs. The developed system will be manufactured, assembled, tested and partly distributed by local SMEs. For the realisation of the succeeding implementation, project cooperations with local SME's mainly in the fields of mechanical construction and automatisation are suggested.
