Introduction

Interpretation of the core content of the standard

Evaluation dimensions	Drawbacks of traditional methods	Innovations of DIN SPEC 91466-1
Quality inspection	High error rate of manual sampling (±15%)	NIR spectroscopy automated sorting verification (error <5%)
Efficiency calculation	Only count the final recycling amount	Value stream efficiency = Σ(actual recycling amount of each sorted product) / total potential recyclable amount of input materials
Document requirements	No unified inspection list	31 mandatory inspection documents + 16 optimization indicators (such as logistics efficiency certificate)

Key points of technical implementation

Quality verification of sorted products must meet the following requirements:

• Near-infrared sorting machines must be manually inspected and calibrated every six months (100 samples/80kg)
• Mixed material objects are classified as >50% by mass
• Unidentified materials are automatically classified as "miscellaneous plastics" or "impurities"

Background of standard evolution

This standard responds to the requirement of Article 16 of the German Packaging Act - the recycling rate of plastic packaging must reach 50% from 2024. By introducing the Value Stream Efficiency Index (formula: η=ΣV_Recovery/(ΣV_Recovery+ΣV_Lose+ΣV_Mismatch)), the sorting process is driven from a "output priority" to a "quality and efficiency balance."
