According to this system behavior, the biogenic broth was heated to specific temperatures and characterized in terms of its morphology, surface chemistry, and crystallinity. The elemental and organic composition of the treated samples was also evaluated and compared to the reference material. The presented results were acquired in an effort to exploit pretreatment scenarios for such a biogenic system that would improve and support a separation process.}, language = {en} } @article{ChairopoulouSchreiberKratzeretal.2020, author = {Chairopoulou, Makrina A. and Schreiber, Alex and Kratzer, Fabian and Wolf, Sebastian and Teipel, Ulrich}, title = {Recycling von marinen Sekund{\"a}rrohstoffen}, series = {Chemie Ingenieur Technik}, volume = {92}, journal = {Chemie Ingenieur Technik}, number = {4}, publisher = {Wiley}, issn = {0009-286X}, doi = {10.1002/cite.201900128}, pages = {405 -- 413}, year = {2020}, abstract = {Austernschalen stellen als Abfallprodukt eine große Umweltbelastung dar und die Wiederverwendung des Materials gewinnt zunehmend an Bedeutung.
