Odour assessment now available in the plastic recycling market

Oct 19 2023

A fresh wind is blowing through the plastic recycling market. Thanks to a new collaboration between plastship, the procurement service provider and platform operator, and 3S GmbH, a specialist in gas measurement technology. This sales cooperation makes 3S's odour assessment technology more directly accessible to a broader group of plastic recyclers and processors, marking an important step towards improved quality assurance standards in the industry. 

At the heart of the collaboration is the OdorCheckerSpot (OCS) from 3S, a test device for odour assessment tailored to the needs of the plastics and recycling industry. The OCS allows for an objective and reproducible assessment of the material quality of recyclates to meet the industry's rising quality demands.   

The flexibility of the 3S OdorCheckerSpot and the use of Artificial Intelligence (AI) allow for efficient odour assessment of various materials. For example, odour assessment of recyclates at different process steps becomes possible - either for continuous verification of process quality or for process optimization. Compared to conventional odour panels, the OCS offers higher reproducibility of measurement results. This is a significant advantage, especially in close alignment with the requirements of VDA 270. Moreover, the OCS scores with significantly lower investment and operating costs compared to sensory panels and analytical solutions. Its user-friendly design encourages easy handling, thus contributing to cost efficiency. All in all, this makes the OCS an attractive solution for the industry. 

"The introduction of 3S technology on the plastship platform opens up new avenues for quality control in plastic recycling," says Andreas Bastian, Managing Director at plastship. "The OCS allows for a quick and reliable odour assessment, a crucial step for the development and acceptance of quality assurance standards." 

Thorsten Conrad, Managing Director at 3S GmbH, adds: "This cooperation elevates quality assurance in plastic recycling to a new level, increasing efficiency and reliability in the production of recyclates."
