BLoP: A Raman and μATR-FTIR Spectroscopy Library for Bioplastic Detection

31 bioplastic item spectra across 8 polymer types, collected from consumer goods to aid environmental pollution detection. The library, created by Madeleine H. Milne and updated in April 2026, validated identification for 79% of samples with Raman and 96% with μATR-FTIR spectroscopy. It is intended for use alongside other commercial and open-access spectral libraries.

Use Cases

• Identify bioplastic materials in environmental samples based on the provided spectral library.
• Validate suspected bioplastic samples by comparing spectra to the 31 reference items.
• Improve detection accuracy for biobased or biodegradable polymers using Raman or μATR-FTIR spectroscopy.
• Benchmark commercial spectral libraries against a dedicated bioplastic reference set.

Strengths

• Contains spectra from 31 items across 8 different bioplastic polymers.
• Demonstrated validation success rates of 79% (Raman) and 96% (μATR-FTIR) for identifying bioplastics.
• Top library matches for tested samples were entries from BLoP 75% of the time for Raman and 73% for μATR-FTIR.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect source bias inherent to the specific consumer goods sampled.
