Extracting gas cylinders and nitrous oxide cartridges from sorting flows

From detection on the conveyor to removal of the object, an automated and traced process.

The operational step

Detecting is not enough: the object must leave the line

Nitrous oxide cartridges, misused as a recreational product, and camping gas cylinders reach sorting centers every day, mixed with household packaging.

These objects are incompressible: they damage sorting equipment and can explode in baling presses or furnaces. They must therefore leave the line before reaching these areas.

Wasoria links detection to action: an object spotted by the Wasoria Box triggers an alert, the information goes to the PLC and the object is removed from the flow.

How an extraction works

Each step is automated or guided, and every detected object is recorded.

1. Detection on the conveyor

The Wasoria Box identifies gas cylinders and nitrous oxide cartridges passing under the gantry in real time.

2. Immediate alert

The line indicator lights switch on and your teams receive the alert on their dashboard and mobile.

3. PLC transmission

Wasoria Pilot sends the detection to the sorting line PLC, which triggers the planned response.

4. Removal of the object

The object is taken out of the flow before the risk areas, by extraction equipment built into the line or by an alerted operator, depending on your center's configuration.

5. Traceability

Every detected object is recorded in Wasoria Pilot, for your reports and audits.

Integration with your equipment

The gantries are installed above your existing conveyors and communicate with your PLCs, without redesigning the line.

Frequently asked questions about dangerous object extraction

Why are there so many nitrous oxide cartridges in sorting centers?

Legally sold for culinary use, these cartridges are misused as a recreational product. Once empty, they are often thrown into recycling bins instead of being taken to a waste collection center, and end up on sorting lines.

What risks do gas cylinders and nitrous oxide cartridges pose?

Incompressible, they damage sorting equipment. When they still contain gas, they can explode in baling presses or furnaces, and flammable gas cylinders can start a fire.

How is the object removed from the flow?

Depending on your line configuration, the object is set aside by extraction equipment controlled by the PLC, or by an operator alerted in real time who knows exactly where to step in.

Does the system work with my current equipment?

Yes. The gantries are installed above your existing conveyors, and Wasoria Pilot communicates with your sorting line PLCs and business tools.

Can we track the number of extracted objects?

Yes. Every detection and extraction is recorded in Wasoria Pilot, which produces reports on detected and extracted objects.
