SHREDDERSORT M18 Meeting in Barcelona

The SHREDDERSORT 18 month general meeting was held on 22 and 23 of July 2015 at the Lenz Instruments, hosted by coordinator company Lenz Instruments. The consortium presented and discussed the progress made since the M12 meeting, and the actions for the next period. Project management and dissemination issues were also discussed.

The main highlights discussed have been:

  • Presentation of the new dual-pulse laser module developed by Monocrom, which provides higher pulse energy than the first laser prototype.
  • Description of the high-speed polychromator, and scanning optics, developed by Lenz Instruments.
  • Demo at LENZ: A demonstration of the high-speed LIBS polychromator is performed at Lenz’s optical laboratory. In the demonstration it is shown the ability of the system to discriminate between cast and wrought aluminum.
  • Management & Dissemination issues: already undertaken and pending dissemination actions are reviewed by the Coordinator in order to help the drafting of the Plan for the Use and Dissemination of the Foreground. Doubts about the financial reporting are solved and each partner’s Use of Resources reviewed.


The next general meeting has not been scheduled yet, as it shall be coordinated with the date for the review meeting. In the meanwhile, specific and reduced technical meeting will be held (both by conference call and at some partners’ premises).


M12 General Meeting in Manchester

The SHREDDERSORT 12 month general meeting was held on 11 Feb 2015 at the University of Manchester, kindly hosted by partner University of Manchester. The consortium presented and discussed the progress made since the M9 meeting, and the actions for the next period. Project management and dissemination issues were also discussed. The main highlights from the partners were:

  • Instituto Superior Técnico (IST) and Laboratório Nacional de Energia e Geologia (LNEG): update and conclusions of the physical and chemical characterisation of shredder scrap. This information been used in the detailed design of the novel sorting processes in the project. The characterisation work package is now complete.
  • Centro Nazionale di Ricerca (CNR): results of Laser Induced Breakdown Spectroscopy (LIBS) analysis of shredder scrap samples, along with algorithms to enable separation of cast and wrought aluminium, and concepts to allow optimization of the laser design.
  • Monocrom: design details and results of their compact, solid-state, laser development for LIBS. They are exploring various options for the laser design, and will shortly settle upon the best design for the LIBS sorting systems, and manufacture prototype lasers for integration and test.
  • Lenz Instruments: presented the design of their high sensitivity, high throughput LIBS spectrometer and signal processing electronics, with the manufacture of components underway.
  • Marwan Technology: details and results of an alternative optical method to gather the LIBS emission from the metal scrap samples.
  • University of Manchester: showed results of simulations and tests for the electromagnetic tensor spectroscopy (EMTS) method to be used for separation of aluminium, brass/bronze, and copper. They showed the built induction coils and the configuration they have designed for the system. Tests will soon begin with these coils and associated electronics on a small test conveyor in the UoM laboratory. The test setup was shown and explained to partners in a tour of the lab. Lenz also gave details of their development of the signal processing electronics for the EMTS system.
  • Jonneum Research: further results of their 2.5D vision system which provides position and shape information about the scrap pieces for the downstream sorting systems. They presented a proposal for integration of the vision system with the EMTS system.
  • The industrial partners CETRISA and Saubermacher provided recommendations from the perspective of system integrator and end-user respectively.

The 18M general meeting was tentatively scheduled for the period 22-24 July 2015 in Barcelona, immediately following the MMME’15 2nd International Conference on Mining, Material and Metallurgical Engineering in Barcelona, which some of the partners will attend.
