We tested bulk samples from all around the world
We conducted all of the tests under the supervision of Halle University in central Germany. The materials were thoroughly analysed in a standardised way (sieve analyses according to DIN 66165, light-microscopic and scanning-electron-microscopic analyses of both input and output materials, quantitative chemical analyses of all sieve fractions (using a mobile XRF scanner). The results were assembled and interpreted in standardised factsheets. Here we display only summaries of the main results. More detailed factsheets with comprehensive results and data are available on request.
