The right way to evaluate a recycling robot is to test a defined picking task against your own baseline—not to choose the system with the highest advertised pick rate. Record the incoming stream, target fraction, belt conditions, labor and quality results first. Then compare candidate systems using the same definitions for recovery, purity, contamination, sustained throughput, availability and downtime under representative loading. Finally, verify the complete installation—vision, tracking, arm, gripper, conveyor, controls, safeguards and operators—through a site trial with written acceptance criteria.
A robot that performs well on one material stream or line position may be unsuitable for another. The following framework is designed for MRF owners, plant managers, engineers and procurement teams making that decision.
1. Start with the task, not the robot
“Robotic sorting” is not one application. A positive-picking arm removes saleable material from a residue or mixed stream; a negative-picking arm removes contaminants from an otherwise valuable fraction. Other applications may involve quality-control checks, bulky-item removal or a dedicated construction-and-demolition line. The target, line position and incoming material determine the mechanical and software requirements.
Write a precise task statement
Describe the intended operation in one sentence that a supplier can test. For example: “Remove aluminium-line contaminants before baling, while preserving cans,” or “Pick cardboard, plastics and coffee cups from a single-stream residue belt.” Include whether the robot must identify black plastics, flattened containers, wet items, bags, overlapping objects or hazardous pieces.

Document the operating envelope
Capture these conditions before requesting proposals:
- Material stream and source (single-stream recyclables, residual municipal solid waste, construction waste, commercial and industrial waste, or another defined feed).
- Target categories and minimum item size, shape and weight.
- Line location, belt width, belt speed, incline, transfer points and available mounting space.
- Loading density, item overlap, presentation quality and the proportion of unpickable or ambiguous objects.
- Contamination profile, moisture, dust, film, black plastics, bulky items and potentially hazardous objects.
- Hourly schedule, seasonal composition changes and peak-loading periods.
- Existing optical sorters, magnets, eddy-current separators, screens, manual stations and downstream quality controls.
A demonstration on a clean, lightly loaded belt is not a like-for-like comparison with a congested production line. Require the candidate to state the stream, loading and line position behind every performance figure.
Establish a matched baseline
Measure current performance using the same material definitions that will be used in a trial. At minimum, record labor hours by task, target recovery, output purity, contamination, throughput, stoppage time, residue and disposal costs, energy and maintenance. Keep the sampling period long enough to include normal variation rather than one favorable shift. If your current team hand-sorts a category differently from a supplier’s definition, resolve that difference before comparing results.

2. Demand comparable performance measures
Ask for a data sheet and test report that separate the following measures. A single “picks per minute” number cannot describe quality, uptime or economic value.
| Measure | What to request | Why it matters |
|---|---|---|
| Target capture or recovery | Percentage of the target material removed or retained, by category and output. | A fast arm that misses valuable items may reduce revenue even when its motion rate is high. |
| Purity | Composition of each saleable output, with the sampling and weighing method. | Purity determines whether a buyer accepts the bale and what price it receives. |
| Contamination | Contaminant types, allowable level and whether ambiguous items count as contamination. | “Clean” must have a defined threshold; otherwise competing claims are not comparable. |
| Sustained picks per minute | Observed rate over a stated period at your belt speed, loading density and target mix. | Short bursts hide replenishment, tracking, jams and operator intervention. |
| Availability | Scheduled time available for automatic operation, with planned and unplanned stoppage separated. | Capacity is a function of uptime as well as arm speed. |
| Fault, jam and intervention rate | Events per hour, mean time to recover and who performs the intervention. | Frequent resets can consume the labor and capacity the robot was meant to save. |
| Peak-load performance | Recovery, purity and stoppages when the belt is at expected maximum loading. | Normal averages do not reveal whether the system fails during surges. |
| Composition sensitivity | Results as target share, contamination, moisture and item presentation change. | MRF feedstock varies by route, season and supplier. |
Specify the observation period, sample size, target categories, rejected or ambiguous items, manual picks, and how stopped time is counted. Ask whether the result is a field measurement, a controlled demonstration, a simulation or a vendor-reported case-study claim. The available published cases use different definitions and conditions; they do not establish a universal acceptance threshold or standardized supplier benchmark.

3. Evaluate the integrated line
The “robot” is only one part of a sorting cell. Vision must detect an object, classify it, track its position on a moving belt and deliver coordinates to the motion controller. The arm must reach the item in time, the gripper must hold it without damaging or dropping it, and the output route must place it in the correct bunker or conveyor. Controls must coordinate all of those actions with existing equipment and safety circuits.
Vision and tracking
Ask what lighting, camera height, belt speed and item spacing the vision model requires. Require examples of performance when objects overlap, rotate, deform or appear partly hidden. Confirm how the system handles an item that is classified late or whose tracked position is lost at a transfer. Recorra’s project manager described retrofitting a sorting arm as a complex process of identifying a moving object and relaying coordinates to the arm: “This was a big team effort, especially since retrofitting the sorting arm into our existing facility brought extra challenges. We’d like to thank the team who enabled the vision system to work with the arm – a complex process of correctly identifying a moving object and relaying coordinates to the robotic arm to grab it as it passes on the conveyor.” (Recorra, July 24, 2025).
Recommended Free Tools
Gripper and item handling
Compare suction, mechanical jaws or hybrid tooling against your actual material. Suction performance can change with dust, holes, wet surfaces and porous cardboard. Jaws may handle irregular or heavy objects but require clearance and can crush fragile packaging. Ask for rated payload, allowable object dimensions, changeover time, spare tooling and the procedure for a failed pick. A gripper that works in a clean demonstration may need different consumables in a dusty MRF.
Conveyor, routing and controls
Confirm belt speed range, usable pick window, tracking accuracy, reject timing and bunker capacity. Identify every required modification: guards, camera mounts, lighting, belt changes, transfer chutes, electrical panels, network connections, compressed air or vacuum supply, and fire or dust controls. Include maintenance access so technicians can clean cameras and service the arm without creating an unsafe reach-in condition.
Commissioning and support
Obtain a project schedule with design review, fabrication, installation, dry commissioning, wet testing, operator training and performance tuning. Recorra reports that its installation was optimized over time; use such accounts to ask who owns model updates and tuning after handover. Panda Ireland’s case study says its vision and robotic sorting installation was completed over two weekends outside production hours. That is one project example, not a guaranteed outage duration for another MRF.

Run a controlled trial before committing to a full deployment, or make production acceptance contingent on measured results. The protocol should be agreed by operations, engineering, safety, finance and the supplier before testing begins.
- Define representative feed. Select samples or live operating windows that reflect normal composition, seasonal variation and expected peak loading. Document source, tonnage, belt speed and loading density.
- Freeze the baseline. Record the current line’s labor, recovery, purity, contamination, downtime, residue and operating cost using fixed definitions.
- Specify target categories. List included and excluded items, minimum size, ambiguous classes and hazardous or unsuitable objects that operators must remove.
- Set measurement rules. State how items are counted, how outputs are sampled and weighed, how manual interventions are logged, and whether planned cleaning or changeover is included in availability.
- Run long enough to expose variation. Measure multiple shifts and, where practical, different feed compositions. Record every jam, reset, missed pick, dropped item and safety stop.
- Calculate separate results. Report capture, purity, contamination, sustained picks, availability, downtime and labor impact independently. Do not combine them into a single score unless the weighting is agreed in advance.
- Review exceptions. Explain results affected by unusual bulky items, wet loads, upstream failures, temporary lighting or manual pre-sorting. Keep those exceptions in the record rather than silently excluding them.
- Sign acceptance criteria. Identify the minimum recovery and purity, maximum contamination, required availability, allowable stoppage and training completion needed for payment or final acceptance.
A 2024 simulation paper models input composition, separation coefficients and robot/conveyor configurations and evaluates simulated purity and recovery (Procedia CIRP/Elsevier, 2024). Simulation is useful for narrowing configurations and designing a trial, but simulated outcomes are not field measurements.
5. Review safety and work design at the site
Require a documented, site-specific risk assessment before installation. It should cover robot reach, pinch and crush points, conveyor access, stored energy, unexpected restart, dropped objects, vacuum failure, sharp or contaminated materials, fire risks and interaction with existing equipment.
Safeguarding and intervention
- Define fixed guards, interlocked gates, light curtains, scanners, emergency stops and safe speeds.
- Map every authorized access route for cleaning, jam clearing, inspection and maintenance.
- Write lockout/tagout steps for electrical, pneumatic, hydraulic and vacuum energy.
- Specify who may reset a fault, what diagnostic information is required and when a supervisor must be called.
- Provide a method for removing bulky, wet, tangled, pressurized or otherwise unsuitable items without reaching into a moving cell.
People and job changes
Document which repetitive picks disappear, which inspection or replenishment tasks remain, and what new work—cleaning cameras, changing grippers, monitoring faults or validating quality—appears. Train affected workers for those duties and plan redeployment before the line is commissioned. Panda Ireland’s Head of Project Management Office, Liam Dunne, said: “Robotics and automation are key to the future of waste management, bringing efficiency repeatability, and to reduce the manual labour we need to sort the materials.” Treat that as an organizational objective, not proof that a particular installation removes every hazard.

Case studies from Bjorstaddalen and Recorra report reduced fatigue or improved safety, but those are operator or vendor statements rather than independent safety evaluations. Applicable requirements depend on your jurisdiction, machinery configuration and installation; use the relevant local regulations and a qualified assessor. The WRAP Materials Recovery Facilities (MRFs) Sorting Guide landing page is a useful reference point, but its linked document contents were not available in the retrieved material, so it should not substitute for a site review.
6. Build a whole-life business case
Compare the robot with the cost of operating the current line and with realistic alternatives, such as adding or reassigning manual sorters or modifying upstream separation. Use your own commodity contracts and disposal charges rather than generic prices.
| Cost or value item | Questions for the model |
|---|---|
| Capital and integration | What are the arm, vision, gripper, controls, guarding, conveyor changes, electrical work, engineering and commissioning costs? |
| Installation downtime | How much production and revenue are lost during construction, testing and ramp-up? |
| Labor | Which positions are removed, changed or redeployed? Include supervision, quality checks, cleaning and fault recovery. |
| Recovered material | How much additional saleable material is captured, at what purity and price, and with what rejected fraction? |
| Residue and disposal | Does improved separation reduce disposal tonnage or change residue classification and charges? |
| Energy and utilities | Include robot power, cameras, lighting, compressed air, vacuum and any new dust-control load. |
| Maintenance and consumables | Budget gripper cups or jaws, filters, belts, camera cleaning, lubrication, spare parts and technician time. |
| Software and service | Identify recurring licenses, remote support, model updates, cybersecurity work and training refreshers. |
| Financing and end of life | Include financing cost, expected useful life, refurbishment, resale or disposal and replacement downtime. |
Sensitivity-test the result for lower input volume, more contamination, lower recovered-material prices, reduced availability, higher maintenance and longer commissioning. Report a range rather than a single payback promise. The cited sources do not establish a generally applicable payback period or independently comparable total cost of ownership.

Case studies are valuable for generating technical questions, not for ranking suppliers or predicting your plant’s result. Keep the stream, configuration, unit and attribution attached to every number.
| Published figure | Context and limitation |
|---|---|
| 55 successful picks per minute | Reported by the International Federation of Robotics in a March 10, 2022 account of FANUC and Recycleye modular systems at MRFs. The account is a reported deployment claim, not a universal guarantee (International Federation of Robotics). |
| 35–60 items per minute | Recorra’s July 24, 2025 post describes the capability of a sorting arm installed at its Purfleet MRF, targeting cardboard, plastics and coffee cups. The post says optimization would continue (Recorra). |
| 98% robot availability | Stated in the Panda Ireland case-study PDF for four AI-powered robots performing negative picking on an aluminium line. The retrieved document has no publication date or sufficient method detail for comparison (Recycleye Panda Ireland case study). |
| Up to 24,000 picks per hour across twelve robot arms | Terex/ZenRobotics’ Remeo case page describes the figure for a Finnish facility handling construction and commercial/industrial waste. It is a case-specific vendor statement (Remeo case study). |
| 5 tonnes per hour of residual municipal solid waste | The Bjorstaddalen case page describes this operating context and dual-action arms using mechanical jaws and vacuum grippers. It also reports 150,000 tonnes per year for an existing construction-and-commercial/industrial plant at the site; those capacities are site-specific statements (Bjorstaddalen case study). |
GFL Environmental describes optical sorting and AI robotics across its facilities and presents company-reported capacity and pick-rate examples (). Treat those figures the same way: ask for definitions, operating conditions and raw measurement records before using them in a business case.

8. Questions to put in every procurement request
- Which exact stream, target categories and line position were used for each quoted result?
- What were belt speed, belt width, loading density, item spacing, contamination and moisture?
- How were recovery, purity and contamination sampled, weighed and calculated?
- Are rates gross or net of cleaning, planned maintenance, fault recovery and manual intervention?
- What happens to missed, dropped, ambiguous, hazardous and oversized objects?
- What availability and fault data are available for a continuous operating period, not just a demonstration?
- Which line modifications, utilities, guards and civil works are included in the price?
- Who tunes the vision model after composition changes, and what is the response time?
- What spare grippers, cameras, filters and critical controls should be held on site?
- What training, documentation, remote access and cybersecurity controls are supplied?
- What acceptance test will be run on our material, and what happens if the criteria are not met?
- Which safety assessment, lockout procedures and worker consultation are included before start-up?
9. Common evaluation mistakes and corrections
Choosing by the highest headline rate
Problem: A peak pick figure ignores missed items, purity, belt loading and downtime.
Correction: Require sustained, net performance and separate quality and availability results under your conditions.
Comparing unlike streams
Problem: A construction-waste result is used to predict performance on residual household waste, or a clean demonstration is compared with a congested line.
Correction: Match stream, target, line position, loading and composition; otherwise label the result as directional only.
Budgeting only the arm
Problem: Vision, belt timing, guarding, controls, utilities, commissioning and spare parts appear later as “extras.”
Correction: Request a complete integration boundary and a line-modification drawing before approval.
Free tools Windows power users keep installed
One-click scans. No signup required.
Ignoring changed work
Problem: Manual sorting labor is removed from the model while cleaning, monitoring and interventions are left unassigned.
Correction: Map every old and new task, train workers and cost the resulting staffing pattern.
Accepting a vendor case study as proof
Problem: A successful reference site is treated as a guarantee.
Correction: Use it to form questions, then verify performance in a documented trial with your material and your acceptance criteria.
Decision rule
Proceed only when the candidate demonstrates the defined task on representative feed, meets separately stated recovery and purity requirements, sustains the required rate at realistic loading, and provides credible availability and intervention data. The proposal must include a complete integration design, site-specific safety review, trained operators, service and spare-parts support, and a whole-life economic model that remains acceptable under adverse sensitivity cases. If any of those conditions is unknown, the next step is to collect the missing evidence—not to infer suitability from a headline pick rate.
