Plastic Sorting Made Easy
Identifying Common Plastics
Using trinamiX technology, the diverse compositions of different plastics can now be precisely determined and thus distinguished via the simple use of a portable handheld device that combines trinamiX data analysis with a mobile app. As such, recycling and recyclability are improved, paying off for both the environment and businesses alike.
With the help of trinamiX NIR Spectroscopy Solutions, all common plastics can be easily identified within seconds. The spectrum ranges from classic polyolefins such as PE, PP and PVC (polyethylene, polypropylene and polyvinyl chloride), to PET (polyethylene terephthalate), which is best known as a material for beverage bottles. In addition, technical plastics such as ABS (acrylonitrile butadiene styrene) or PA (polyamide), whose distinction is particularly important for the recycling companies, can also be correctly identified in the field (especially in blends with other plastics). trinamiX can integrate additional materials according to customer requirements.

Distinguishing PA6 from PA66
PA6 and PA66 belong to the most sought-after engineering plastics. Thanks to their robustness, they are suitable for a wide range of applications – from fishing nets to resilient components. Since PA6 and PA66 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 PA6 and PA66 has gained traction in recent years in light of growing requirements within the recycling industry.
As a result, the production of high-quality single-grade plastic recyclates - including PA6 and PA66 - is becoming increasingly lucrative. trinamiX now supports the reliable differentiation between polyamide 6 (PA6) and polyamide 6.6 (PA66) with its Mobile Near-Infrared Spectroscopy Solution. Within seconds, plastic waste from the two polyamides can be sorted using a handy measuring device as part of trinamiX’s solution. With this new application, trinamiX is responding to customer wishes and expands its broad offering for plastics sorting.
Distinguishing between HDPE and LDPE - Determining the ratio of PE to PP
In addition to quickly distinguishing between HDPE and LDPE, the ratio of PE to PP in mixed plastics can be precisely determined as easy as pushing a button. Thanks to the flexibility of a handy measuring device, the process for obtaining high-quality PE and PE/PP recyclates is now significantly enhanced.
Polyethylene (PE) is the most widely produced plastic in the world and the most popular thermoplastic for foils and packaging. Depending on its density, PE can be divided into HDPE (high-density polyethylene) and LDPE (low-density polyethylene). While the similar characteristics of HDPE and LDPE lead to overlaps in their respective applications, differences in their mechanical properties have an impact on their processing and the subsequent recycling process. In the context of recycling, a separation by type has a favorable effect on the quality of the recyclate.
