Overview
Screening- / Test-Methoden für polymere Verunreinigungen in Kunststoffen sind für die Verwirklichung der Kreislaufwirtschaft unerlässlich. Insbesondere im Umfeld Rezyklat-verarbeitender Unternehmen besteht Bedarf nach einer robusten Analytik, die gleichzeitig möglichst repräsentative Aussagen liefert. Im Folgenden werden chromatographische und thermische Methoden hinsichtlich ihrer Eignung für diese Aufgabe, mit besonderem Fokus auf dem Machbarkeitsnachweis einer neuartigen thermischen Analytik verglichen. Ihre jeweiligen Vorteile und Grenzen werden am Beispiel von Polyolefin-Neuwaremischungen mit bis zu 1 Gew.-% PP in HDPE untersucht. Mit dem Machbarkeitsnachweis wird eine Quantifizierung von bis zu 10 Gew.-% PP in HDPE (High Density Polyethylen) erreicht, während kleinere Konzentrationen bis zu 2 Gew.-% nachweisbar sind. Ungewöhnlich große Probenmengen von bis zu 2 g werden für diese Analyse verwendet, ohne dass eine Probenvorbereitung erforderlich ist, was zu einer hohen Repräsentativität führt. Darüber hinaus ist die Quantifizierung der Polymerverunreinigungen ohne große Schwierigkeiten möglich.

Overview
Screening methods for polymeric impurities in plastics are indispensable in pursuing circularity. Especially for recycling companies, there is a need for robust analytics with as much representability as possible. The suitability of chromatographic and thermal analysis methods for this problem was compared, and a novel thermodynamical testing method for compositional analysis and material identification was introduced. Their respective advantages and limitations are explored using the example of model virgin polyolefin mixtures down to 1 wt% PP in HDPE (High-Density Polyethylene). With the novel method, a quantification down to 10 wt% of PP in HDPE is achieved, while smaller concentrations are detectable down to 2 wt%. Unusually large sample sizes of up to 2g are used in the analysis without the need for sample preparation, resulting in high representativeness. Moreover, quantification of the polymer impurities is realized with little difficulty.

Abstract
A crucial issue in the plastic recycling industry is the loss of quality in recycled materials due to cross-contamination, which leads to excessive material losses. Determining cross-contamination levels in recyclate batches fills a crucial gap in quality control, helping to identify suitable applications and enhance the value of the material stream. A key challenge lies in selecting a sample size that accurately represents the large variability within the tons of batches processed daily. This work presents a data analysis framework to accurately estimate cross-contamination levels in plastic recyclate batches and determine the sample size required to meet industry demands, while accounting for both analytical and sampling errors. Additionally, this work introduces MADSCAN®, a novel, scale-free thermal analysis technique that allows for the analysis of the sample sizes identified by the framework. Objectives include providing crucial information to industry stakeholders, assisting regulators in establishing quality control processes, and guiding technology providers in advancing measurement techniques for the circular economy, with a focus on meeting sample size and accuracy requirements.
