36 TRADE SHOW REVIEW PET planet Insider Vol. 21 No. 03/20 www.petpla.net TRADE SHOW review PART 3 Efficiency and quality in plastic recycling The machine and plant manufac- turer Herbold Meckesheim, Germany presented tried and tested process solutions for the treatment of plastic waste in Düsseldorf in addition to its wide range of machines. The solu- tions from Herbold are based on 40 years of experience and continuous developments in post-industrial and post-consumer applications. “Size reducing, washing, separating and drying and agglomeration are our main processes. Our customers value our wide range of machine options and the ability to obtain custom plant designs from a single source. With our focus on the circular economy, we are fully in line with the current spirit of the times and with one of the main topics of the K 2019 trade fair”, said Werner Herbold, one of the two general managers. At the booth Herbold presented machine innovations from the pre- shredding sector, granulators, and washing lines. Herbold machine solu- tions are for the following applications: post-industrial and post-consumer films, post-consumer hard plastics, PET bottles, PET trays, big bags and other monofilaments, Tetra packs and pulp waste. The new VWE 700 prewashing unit was presented. An important compo- nent in the Herbold film washing line is the multistage prewashing unit, which captures coarse foreign bodies and reduces the mineral fraction, both to protect the subsequent machines. The remainder is also gently prewashed. Herbold said that they have optimised this process step even further by increasing the throughput performance for films, optimising the flow of water, and integrating a baffle plate thickener into the unit to clean the process water, and therefore remove contaminants directly on the unit. With the new WS 60/210 shredder another highlight was presented. The demand for high-performance shredders that can process entire bales is increas- ing, especially when used in washing lines. Therefore Herbold presented the EWS 60/210 for the first time at the trade fair. This shredder was developed for dry operation as well as for wet operation. It has a maintenance-friendly design with a high capacity. In many plants, the crusher is the first stage in the process. In this stage, foreign bodies are often impos- sible to avoid. For this reason Herbold has taken some of the special features of this stage into account. “We focus on making a perfect wear-protected rotor that, in addition to custom knife configurations, is equipped in particular with bolted armor plating and a special grinding chamber seal”, stated Daniel Zeiler, Head of Sales. The time-con- suming hardfacing of rotors is therefore unnecessary. The two-sided belt drive is low-maintenance, and to safeguard against foreign bodies, there is a clutch that prevents damage to the machine when uncrushable feed material is encountered. The maintenance concept is tailored to ensure optimal accessibility based on ergonomic considerations. The first machines are already successfully in use at customers in Europe. www.herbold.com Clariant, PET Engineering and Husky presented the Erit bottle, a 100% rPET bottle The problem of using post consumer recycled material is that it creates an unsightly side effect like yellowing that is not acceptable by the industry and the consumer. Clariant worked on this by definding colour solutions that could be used in recycled PET. The Clariant team decided for dark black and dark green colouring. The new Cesa Nir black colour which was used for the Erit bottle is detectable in standard sorting systems and is therefore again recyclable. Two other colours were pre- sented: one green-effect colour and a translucent blue, the bottles are capped by a metallic looking plastic cap. Husky Injection Molding Systems Ltd. a leading supplier of injection moulding equip- ment and services to the PET bottle market, has developed the tooling for the preform from which the Erit bottle is blown. Husky has optimised the weight and properties of the finished bottle. Husky supported this innovation also with its tethered closure. www.clariant.com www.husky.co www.petengineering.com Mr Abdelhadi Jaga, Sales spare parts, led us over the booth.
