GAO’s Recycling Stream Sorting and Tracking Systems

Recycling Stream Sorting and Tracking Systems from GAO help municipalities, material recovery facilities (MRFs), waste haulers, and industrial recyclers improve material classification, collection accuracy, and downstream traceability. These systems can operate using RFID-only, BLE-only, or optional RFID-BLE hybrid architectures, depending on facility layout, container type, collection vehicle design, and required data visibility. They support automated identification of bins, bags, carts, and recyclable streams as they move through curbside pickups, tipping floors, conveyors, optical sortation lines, and baling stations. With decades of engineering and R&D experience supported by headquarters in New York City and Toronto, GAO helps organizations optimize waste diversion programs, reduce contamination, and capture detailed analytics that manual processes cannot provide. Our solutions perform reliably in harsh environments such as outdoor curbside routes, dusty MRF floors, and noisy industrial sorting lines.

Comprehensive System Description, Purposes, Issues Addressed, and Benefits

Recycling Stream Sorting and Tracking Systems developed by GAO automate the identification and monitoring of recyclable materials across residential, commercial, and industrial waste streams. RFID-only deployments rely on rugged tags affixed to bins, carts, or bundled materials, enabling precise data capture during curbside lift events, facility intake scanning, conveyor transfers, and baler output. BLE-only deployments use long-range beacons for zone-level detection, providing visibility into container movements across large tipping floors or distributed sorting stations where line-of-sight scanning is challenging. These systems support contamination reduction workflows, automated route auditing, material accountability, and throughput optimization across MRF machinery such as shredders, eddy-current separators, ballistic screens, and optical sorters. GAO engineers RF fields designed to withstand metal containers, dust buildup, shock, vibration, and variable outdoor conditions. Facility managers, route supervisors, machine operators, environmental compliance teams, and sustainability program leaders gain reliable data to improve diversion efficiency and reduce operational losses.

RFID-Only vs BLE-Only vs Optional Hybrid

RFID-Only

• Enables exact container, load, or bundle identification
• Ideal for curbside pickups, load verification, and conveyor-based sortation points
• Provides high-confidence reads despite dust, vibration, and high-speed equipment
• Supports contracting audits and detailed material tracking

BLE-Only

• Provides long-range presence and zone tracking for bins, carts, or bulk materials
• Useful for large tipping floors, multi-bay sorting areas, and extended outdoor facilities
• Supports broad environmental awareness rather than granular item-level identification

Optional Hybrid (RFID + BLE)

• Best applied when both precise bin identity (RFID) and broad zone localization (BLE) are required
• Useful for large MRFs with multiple conveyor levels and distributed processing areas
• Applied selectively based on technical advantage, not as a standard GAO offering
