Extrusion International 6-2022

25 Extrusion International 6/2022 Ready-Made Subsystem for Industrial Shredder Control  Industrial shredders crush materials made of plastic, wood, metal, and waste to a required size. Depending on the requirements, each shredder is made up of different components, which are to be operated efficiently without damaging the machine. In addition to robust hardware, an extensive software package is needed to control the shred- der. However, the software programming requires appro- priate know-how and ties up the manufacturer’s capacities. With the Motion-Axis Shredder software template, the automation specialist Baumüller in Nuremberg is introduc- ing a template for the recycling branch to the market. It saves developers lots of time, particularly during a project’s start phase, and they can fully concentrate on the process programming. The template contains a large number of the required machine functions as well as motion modules for actuating the servo motors, templates for the machine vi- sualization, and functions such as EtherCAT diagnosis, com- missioningmode, load balancing, andwater cooling control. The already programmed subsystem contains fre- quently needed machine functions for crushing and can be easily loaded into the shredder control system. The movements then merely have to be parameterized. The machine programmer no longer has to worry about the basics during development. For the machine builder, this means a faster time to market, and significantly reduced development expenditure. The software package is suitable for single and twin- shaft crushers, with and without feeder, and can be inte- grated into different hardware concepts. Baumüller Gruppe www.baumueller.com Preprogrammed and can be integrated immediately: With the Motion-Axis Shredder software template, it is possible to control high-performance shredders with up to two crusher units, each with two dual-winding motors as well as a motor for the feed (Photos: Baumüller) Improved diagnostic options: Among other things, the user interface can be used to call up the current template status or to check the interface values Agreement on the Production and Procurement of Pyrolysis Oil fromMixed Plastic Waste  BASF has concluded a framework agreement for the pur- chase of pyrolysis oil from mixed plastic waste with ARCUS Greencycling Technologies. The two companies want to con- tribute their respective know-how to the value chain in order to return plastic waste that is not recycled mechanically in the senseof a circular economy and reduceCO2 emissions. ARCUS will supply BASF with pyrolysis oil and expand its capacities in the coming years. BASF will use the oil in its production plants as a rawmaterial for the production of Ccycled™products. The ARCUS process demonstration unit built in Frank- furt is the first of its kind on a commercial scale in Germany and produces pyrolysis oil from mixed plastic waste that is not recycled mechanically. “With the guaranteed purchase of the oil produced, ARCUS can build further plants with higher capacity and thus make a significant contribution to closing material cycles together with BASF,” said Daniel Odenthal, Chief Operating Officer of ARCUS Greencycling Technologies. The agreement foresees the take-up to be increased to up to 100,000 tons of pyrolysis oil per year. The agreement is another building block in the expan- sion of BASF’s ChemCyclingTM business, which focuses on the chemical recycling of non-recycled post-consumer plastic waste on an industrial scale. BASF will feed the py- rolysis oil supplied by ARCUS into its production network in Ludwigshafen, replacing fossil resources. The proportion of recycled raw material is allocated to products manufac- tured in the Verbund using a mass balance approach. The attribution is checked by an independent auditor. The products that bear the name suffix “Ccycled™” have exactly the same properties as con - ventionally manufactured products. Customers can therefore process them in the same way and also use them in applications that place high demands on quality and performance.
