Ulrich Thiele, President, Dr. Thiele Polyester Technology went to some recycling process details and reported about chemical polyester recycling and its challenges and hurdles to enter industrial scale. Some of the final conclusions are. His main conclusions are process technologies of chemical recycling by glycolysis, hydrolysis or methanolysis are available and lower entrance barrier for chemical polyester recycling are having those polyester producing companies which are still possessing at site DMT/PTA production which is enabling the joint use of the existing equipment, technology and know how for chemical polyester recycling.
Xu Jian, Gneuss Shangha, Gneuß Kunststofftechnik GmbH reported about devolatilizing and filtration as key factors in the production of PET fibres. After five years of development and a successful introduction to the industry the new MRS devolatization and extrusion technology is available for a broad range of applications. Especially for fiber production the MRS provides highest degassing efficiency available in the market at moderate vacuum >25 mbar required which is efficient for most applications. Karlheinz Herbold, President, Herbold Meckesheim GmbH presented the latest design of Herbold PET bottle washing lines as state of the art in this technology. The modular design of the Herbold washing lines allows customers to start with basic process steps or to add these steps or components to existing lines.
Wang Biao, OHL Beijing Representative Office reported about Advantages of OHL batch process in “Bottle To Bottle” recycling. One major advantage of the OHL technology is the high flexible SSP which allows to produce at one and the same line pellets of lower IV in a range of 0,75 – 0,78 dl/g, in medium IV in a range of 0,80 – 0,84 dl/g and in high IV in a range of 0,90 – 0,95 dl/g.
Andreas Christel, Product Manager Thermal Processes, Buhler AG presented the latest technology features of Buhler`s solid state polycondensation for PET bottle recycling. Especially to produce food grade PET flakes at lower and medium capacity in a range of 5 000 – 20 000 t/a the so called “SSP leaN” which is providing an IV increase between 0,1 and 0,2 dl/g (optional 0,3 dl/g) provides an efficient solution for PET recycling. One outstanding highlight of the conference was provided by Andrew Noone,Managing Director, PCI PET Packaging, Resin & Recycling Ltd with his speech about the global trends in PET bottle recovery and reuse. Especially the compressed overview about the bottle collection around the world and in China and the expected market development has been presented in instructive graphics.
