Simple plastic sorting with NIR spectroscopy


With its Mobile Near-Infrared Spectroscopy Solution, trinamiX GmbH, a wholly owned subsidiary of chemical company BASF SE, Ludwigshafen/Germany, now supports the reliable differentiation between polyamide 6 (PA 6) and polyamide 66 (PA 66). Within seconds, plastic waste from the 2 polyamides can be sorted using a handy measuring device as part of trinamiX’s solution.

Since PA 6 and PA 66 have similar properties, they are used interchangeably in numerous applications – and it is virtually impossible to distinguish them with the naked eye. At the same time, the separation of PA 6 and PA 66 has gained traction in recent years in light of growing requirements within the recycling industry.
In addition to distinguishing PA 6 and PA 66, trinamiX Mobile NIR Spectroscopy Solution can already identify all common plastics – from classic polyolefins such as polyethylene (PE) and polypropylene (PP), to polyethylene terephthalate (PET) and engineering plastics such as acrylonitrile butadiene styrene (ABS). Recycling companies as well as manufacturers, traders and processors of goods made from recyclate benefit from a flexible and mobile solution that offers user-oriented applications for the sorting of plastic components and packaging materials.
