Strategy Carbon Management, BASF. “The use of glass fibres and other additives with a reduced CO2
e footprint is in preparation.” Also new is Ultraform BMB, which is ISCC+ Biomass Balance certified, and which BASF says contributes additionally to the use of renewable raw materials in the production chain and allows a PCF reduction of approximately 70%. BASF, Mercedes-Benz, Pyrum Innovations and
Witte Automotive say they have successfully closed a material cycle to produce automotive compo- nents from mass-balanced plastics. A bow door handle for selected Mercedes-Benz models made from mass-balanced Ultramid PA6 reinforced with 30% glass fibre will start series production this year. To produce the plastic for the handle, BASF combined alternative raw materials in a mass balance approach: pyrolysis oil generated at Pyrum Innovations from scrap tyres, and biomethane from agricultural waste and food industry residues. The resulting compound features the same properties as a virgin compound. Mass-balanced products will be used for bow door handles for the Mercedes-Benz S-Class and the EQE this year. The jointly developed solution approach will later be transferred to a crash absorber for the Mercedes-Benz S-Class.

Bio-based Akulon PA 6 from DSM is used exten- sively in this Bugaboo stroller
On track with 2030 targets DSM Engineering Materials says it remains on-track to meet objectives it set itself at K2019 to have a complete portfolio of bio- and/or recycled- based alternatives for its range of polyamides and polyesters by 2030. This year, it launched a 100% bio-based version of Stanyl PA 46, with half the carbon footprint of regular Stanyl. At K2022, it also discussed partnerships with Schneider Electric and with Samsung Electronics on applications using, respectively, recycled ocean plastics and recovered fishing nets in Akulon RePurposed PA 6. DSM has set itself a target of cutting greenhouse gas emissions in half by 2030 compared to 2016.
At the show, the com- pany discussed a partnership with children’s stroller maker Bugaboo, Fibrant, and Neste, that has enabled the launch of an entire Bugaboo stroller portfolio made with bio-based materials. The majority of the strollers’ plastic parts are made using Akulon 100% bio-based B-MB PA 6, which in turn is made using bio-based feed-

stock from both Fibrant and Neste. DSM Engineer- ing Materials uses a mass-balancing approach with renewable waste and residue raw material to enable an approximate 75% PA 6 carbon footprint reduction compared to conventional PA 6 and up to 24% of the entire stroller. K 2022 was the first opportunity for Domo Chemicals, another leader in polyamides, to present its entire range of Technyl solutions to a global audience (Domo acquired Solvay’s Euro- pean Performance Polyamides business in 2020, and is now using the Technyl brand across its portfolio).
It showed new solutions addressing needs in lightweighting, metal replacement, thermal management and e-mobility. The Technyl 4Earth portfolio, which includes grades containing 50-100% recycled material, coming from airbags and fibre production, continues to grow. Designed for cooling applications, Technyl 4Earth A1E 218 V30 BK 34NG LP is a sustainable variant of an existing coolant resistant grade, Technyl A 218 V30 BK 34NG, for example. For E&E applications Technyl 4Earth flame-retardant polyamides, in grey and white, are based on recycled feedstock with reduced CO2
emissions.
Currently, around 10% of Domo’s product sales are from circular solutions. The company plans to grow this to 20% by the end of the decade, and to 30% by

2035. It says it is exploring technologies and solutions around depolymerisation, polyamide dissolving, and new feedstock recycling. Covestro premiered an e-mobility application for Makrolon RE, a polycarbonate
