New ways to recover polyamide from vehicles


BASF presented two new technolo- gies at K2025 – to recycle polyamide 6 from end-of-life vehicles. The first is based on depolymerisation – in which the PA6 is broken into monomers – while the second is a solvent-based process. Both are running as pilot projects. BASF says that metals have long


been recovered from vehicles, but around 200 kg of plastics per vehicle often end up being incinerated. The new technologies aim to change this, in view of upcoming regulatory requirements of the End-of-Life Vehicle Regulation (ELVR). The chemical recycling project


allows recycling of contaminated parts such as used oil pans supplied by ZF Group. In the first step, polyamide chains are broken down into their original building blocks. Next, the mix is purified to obtain the monomer caprolactam. The material is


SI realigns its sales structure


SI Group is to align its sales structure with specific markets. The US-based additives supplier will focus on five key markets – one of which is plastics and rubber. At K2025, Paul Tilley, senior vp of sales and business development, said the group is aiming to improve sales intensity by strengthening customer relationships and provide a more unified approach to market coverage. � www.siigroup.com

ZF made this stabiliser link for Mercedes-Benz, using polyamide recovered using BASF’s chemical recycling technology


then repolymerised into polyam- ide. ZF has processed the recycled material into a complex chassis component, called a stabiliser link, for Mercedes-Benz. “What was considered non-recyclable is now the starting point for new products,” said Martin Scheuble, team leader of circularity for engineering plastics at BASF. The second project extracts polyamides from automotive shred- der residue (ASR) – a mix of various materials. The polyamide fraction obtained in this way was used as the starting material for a solvent-based recycling process as part of the pilot project. Here, the polymer chain is selectively dissolved with the aid of a


suitable solvent, then purified and reprocessed into PA6 compounds. The technology was validated using a chain guide rail in series production at Mercedes-Benz. The components were made and tested under near- series conditions by project partner Pöppelmann. “This shows that solvent-based recycling is a practical alternative for plastics that are difficult to recycle mechanically,” said Steffen Meyer, team leader for production technol- ogy at Pöppelmann. �www.basf.com


Nissei Plastic and RWTH start research project in recycling


Nissei Plastic has begun a research project with RWTH Aachen University in plastics recycling technologies. This research, which uses


Nissei’s moulding machines, is also likely to involve other


European manufacturers of moulds and control equip- ment. It aims to develop high-precision moulding technologies for recycled plastics, raise energy efficien- cy and reduce the output of defective products using AI.


The project will focus on four main themes: moulding technologies for recycled materials; sandwich mould- ing; expanding the use of recyclates, through better understanding of their properties; and using AI image inspection.


Nissei will use an all-elec- tric injection moulding machine from its partner Negri Bossi. The 180-tonne machine incorporates a hot runner valve gate system that facilitates sandwich moulding with recyclate. �www.nisseijushi.co.jp
