Hyperspectral AI sorting technology precisely separates 12+ plastic types from household and industrial mixed waste plastics — sorting purity ≥98%, single-machine throughput 3-8 tons/hour
Global annual mixed waste plastics exceed 150 million tons; advanced sorting technology is the key to unlocking this value
China alone produces 60+ million tons of waste plastic annually, with over 40% being mixed household plastics — currently most are incinerated or landfilled
EU requires 55% plastic packaging recycling rate by 2030; China's "Waste-Free City" initiative drives mandatory sorting — mixed plastic sorting is becoming a required capacity
Mixed plastics sell for 500-1,000 CNY/ton; after sorting, single-material streams (PE, PP, ABS, etc.) fetch 3,000-8,000 CNY/ton — a 3-10x value increase
Household waste contains PE, PP, PS, ABS, PVC, PET, PA, PC and more — often 8-15 types in a single batch, with widely varying physical properties
Composition varies significantly by season, region, and source — a sorting setup that works today may fail tomorrow, requiring constant parameter adjustment
Traditional sorting struggles to balance high purity with high yield — pushing purity to 95%+ often causes yield to drop below 70%, undermining economics
"Coarse-to-fine" multi-stage sorting architecture — from mixed waste to pure single-material streams
Remove metals, glass, stone, and other non-plastic contaminants; size classification to ensure uniform material size for downstream sorting
First-pass hyperspectral sorting, broadly separating into PE/PP group, PET group, PS/ABS group, and PVC — throughput 5-8 tons/hour per unit
Second-pass hyperspectral sorting on each group, precisely separating individual plastic types — PE from PP, ABS from PS, etc. — purity ≥98%
Optional color sorting for high-value applications — separating clear, light blue, green, and other colored fractions within each material type
224-band SWIR hyperspectral captures unique molecular spectral signatures — distinguishing PE from PP, ABS from PS with >99.5% accuracy, far beyond NIR
Conventional NIR cannot detect black plastics (carbon black absorbs NIR). Our SWIR hyperspectral penetrates carbon black to identify the base polymer — a critical advantage for automotive and electronics recycling
AI model automatically adjusts to batch composition changes — no manual recalibration needed when feedstock varies. Model continuously improves with operational data
Modular units can be configured for any capacity from 3 to 30+ tons/hour. Add or rearrange modules as your business grows — no rip-and-replace needed
Multi-stage progressive sorting achieves >98% purity while maintaining >90% yield — breaking the traditional purity-yield trade-off
Real-time monitoring of sorting performance; automatic parameter optimization across all units; production analytics and batch quality reporting

Sorted from municipal solid waste — packaging containers, household items, toys — typically 8-15 plastic types mixed together
Plastic housings from waste electronics — ABS, HIPS, PC, PP — high-value materials requiring precise separation
End-of-life vehicle plastics — PP bumpers, ABS interior trim, PA engine components — large volumes with good recycling potential
Production rejects, purgings, and post-industrial waste — cleaner than post-consumer but still requires material-type separation
6-unit hyperspectral sorting line: 2 coarse sort + 4 fine sort, with automated feeding and conveying system
"We went from a waste transfer station to a high-value material recovery facility. Baicheye's system paid for itself in under a year."
4-unit hyperspectral sorting line with black plastic detection capability and flame retardant identification
"The ability to sort black plastics was the deciding factor. No other technology on the market could do this reliably."
Extended Producer Responsibility (EPR) schemes expanding globally — producers will be required to fund and achieve recycling targets, driving demand for high-purity sorting
Deep learning models will continuously improve sorting accuracy and adapt to new material streams without hardware changes — software becomes the key differentiator
Mechanical sorting + chemical recycling will form closed-loop systems — sorted streams feed both mechanical and chemical processes for maximum value recovery

With a two-stage fine sorting configuration, we consistently achieve ≥98% purity for target materials. For applications requiring >99.5% purity (e.g., food-grade), a third sorting stage can be added. The exact configuration depends on your feedstock characteristics and target specifications.
Our SWIR hyperspectral technology (900-1700nm) penetrates carbon black pigmentation to identify the base polymer. This is a unique capability — conventional NIR (800-1100nm) is completely absorbed by carbon black and cannot detect black plastics at all.
Our AI model is designed for this exact scenario. It continuously monitors spectral patterns and automatically adjusts classification thresholds. No manual recalibration is needed for normal compositional variations. For significant changes (e.g., new material types), we can remotely update the model.
Yes. Our modular architecture supports easy expansion. You can start with a 2-unit system and add more units as your capacity grows. All units connect to the same cloud platform for unified management.
