MATERIALS / RECYCLING PETplanet Insider Vol. 21 No. 06/20 www.petpla.net 29 made from recycled PET. Sheets for the usage as protective packaging (lu´um) or face shield (Invemask) need to be free of any contamination caus- ing coloured spots or wholes in the sheets. Decisive for the use of recycled PET is that it must be processed in the purest form possible and optimally cleaned in the recycling process. Therefore, Invema uses a clean- ing system from its long-term partner CHT Group. The combination of an effective cleaning machine from Herbold and a powerful cleaning liquor consisting of caustic soda and Tubiwash enables Invema to reach the best transparency for the trays and face shields. Besides this, Tubifoam and Tubiwet support the separa- tion of the materials result- ing in the needed material purity of PET. CHT Group can contribute its strength from individual recipes and strong technical service to support Invema not only to make the actual process most efficient, but also to save important resources such as energy and water, thus protecting the environ- ment. Other than the recycling process the CHT Group makes further important contributions to interrupting the infection pathways of the coronavirus. Disinfect- ants for hand and surface hygiene are produced to help at various locations worldwide as well as special coatings for so-called “textile face masks” and profes- sional medical workwear partly made from recycled PET. Thus, PET provides strong assistance to make our everyday life more comfortable and safer. In times like we are in now, the advantages of circu- lar economy are obviously and the effort to give a PET bottle or tray a second life is worthwhile. www.cht.com
