Hyperspectral Fluorescence Images of Black Plastic Particles for Recycling

Florian Gruber provides imaging fluorescence measurements of black plastic particles in the spectral range from 500 nm to 900 nm. The data contains measurements for approximately 400 particles each of 14 polymers, including HDPE, PP, PA6, and TPU, obtained from a recycling plant. The objective is to train classification models for recycling black plastics.

Use Cases

• Train polymer classification models based on hyperspectral fluorescence signatures.
• Develop computer vision systems for recycling plants based on imaging fluorescence data.
• Analyze material properties of cryogenically ground plastics based on spectral measurements.
• Benchmark hyperspectral data analysis methods for industrial process monitoring.

Strengths

• Data covers 14 distinct polymer types, including variants with additives like glass fiber and flame retarder.
• Approximately 400 particles were measured per polymer type, providing multiple samples for analysis.
• Measurements were made with a dedicated lab system using a 2000 mW 450 nm diode laser and an 870 nm LED for illumination.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
