The HPB Intelligent Optical Sorter integrates cutting-edge AI vision technology with high-precision sensing systems. Leveraging multi-dimensional recognition capabilities—including color, material type, labels/markings, and shape—it accurately identifies various plastic bottles and materials to achieve highly efficient and refined sorting. This solution drives the plastics recycling industry toward intelligent, high-purity, and high-recovery operations.

A premium intelligent sorting solution purpose-built for PET bottle recycling lines and municipal solid waste (MSW) treatment centers. Equipped with advanced color recognition and polymer composition detection technology, it fully automatically sorts multiple plastic types such as PET, HDPE, and PP with an overall sorting accuracy exceeding 99%. It effectively improves material recovery rates and end-product purity, reduces costs, increases efficiency, and enables resource circularity.

• Dual-Sensor Synchronized Detection – Dual-Level Precision Recognition

  • High-end InGaAs-SWIR short-wave infrared camera: identifies polymer types based on material molecular structure, rapidly distinguishing PET, HDPE, PP, and other plastic grades.

  • High-resolution RGB camera: captures subtle color differences in real time, precisely sorting clear bottles, blue bottles, green bottles, and contaminated mixed-material bottles for finer classification.

• Proprietary AI Deep Learning Algorithms – Adaptive to Complex Operating Conditions

  • Intelligently distinguishes bottle body, cap, and outer label, and accurately removes impurities such as metals and silicone.

  • Features an autonomous iterative learning system that quickly adapts to new material types, complex printed labels, and special material recognition.

  • Effectively solves industry sorting challenges including black plastics, reflective materials, and crushed/deformed bottles, with strong adaptability to varying working conditions.

• Belt-Type High-Efficiency Sorting Architecture – Modular and Flexible Configuration

  • Modular custom design: selectable belt widths of 1200mm, 2000mm, or 3000mm, with throughput from 2 to 6 tons per hour, perfectly matching small, medium, and large production capacities.

  • Precision pneumatic ejection system: equipped with 88 to 224 high-speed nozzles, millisecond-level response time, ejection positioning error ≤ ±2mm, ensuring stable and efficient sorting with minimal material loss.
