Thermoplastic Recyclables

98.4% Confidence
Recommended Bin: Yellow / Commingled Recycling Bin
Latency 4.70 ms
Hardware CUDA (FP16)
Model EfficientNet-B0 (Two-Stage Transfer)

Preparation & Handling Steps

  • Rinse residue thoroughly to avoid contaminating paper and cardboard in mixed bins.
  • Crush containers and bottles to minimize transportation volume.
  • Check SPI resin identification code (#1 PET and #2 HDPE are widely recycled).
Environmental Impact

Recycling 1 ton of plastic saves ~5,774 kWh of electricity and 16.3 barrels of crude oil.

Biodegradation: 450 - 1,000 years

Probability Distribution (All 10 Classes)

Visualizing Model Decisions

Grad-CAM computes gradients at the final convolutional layer of EfficientNet-B0 to reveal which visual features influenced the decision.
