NETZSCH Launches AI-Powered Polymer Qualification Tool for Recyclate Quality Control

Why It Matters

Accurate, rapid recyclate qualification removes a key barrier to higher recycled content, helping manufacturers meet tightening EU regulations and cost pressures while preserving product performance.

Key Takeaways

• AI quantifies polymer mix from single DSC measurement.
• Detects contamination down to 1% with 3‑6% RMSE.
• Supports PP, HDPE, LDPE, LLDPE; database expanding.
• Enables faster, data‑driven recycling decisions.
• EU 2030 rules demand documented recyclate composition.

Pulse Analysis

Recycling plastics at scale has long been hampered by a lack of transparent material data. Traditional checks such as melt‑flow index or FTIR provide only qualitative insights and often fail on dark or multilayer films, forcing manufacturers to over‑engineer products or reject batches. As circular‑economy targets tighten, the industry needs a robust, quantitative method to assess polymer blends and contaminants quickly, ensuring that recycled content can be trusted throughout the supply chain.

Proteus Now Quantify meets that need by marrying DSC thermal fingerprinting with machine‑learning algorithms trained on a wide spectrum of virgin polyolefin grades. The software deconvolutes overlapping crystallization peaks, delivering composition percentages with 1% detection limits and 3‑6% root‑mean‑square error. Integrated directly into NETZSCH’s DSC hardware, the workflow requires a 10‑mg sample and standard 10 K/min heating rates, after which analysis completes in seconds. For composites, users can supplement the DSC data with filler fractions derived from TGA or burn‑off tests, enabling precise polymer‑only assessments.

The timing aligns with upcoming EU legislation that, from 2030, will obligate recyclate suppliers to provide documented origin and composition for market entry. By offering a fast, repeatable, and auditable qualification tool, NETZSCH positions itself as a critical enabler for automotive, electronics and construction sectors seeking certified recycled inputs. Ongoing expansion of the material database to include engineering polymers such as PET, PA and ABS, coupled with partnership programs for data sharing, promises to broaden the tool’s applicability and accelerate adoption across the global plastics value chain.
