In a modern plant the machines do most of the work. But there are always objects the automation does not catch: a black plastic the sensor cannot read, a hazardous item that has no business being in the flow, a textile that slipped in among the recyclables. This is where the manual sorting cabin comes in.
It is not a table with people standing around it, it is a designed space. Enclosed, brightly and evenly lit, continuously ventilated so dust and odour are extracted, climate-controlled so the temperature stays stable year round, with stations at a height calculated to reduce physical strain. See the full range of waste sorting equipment and where each machine sits in the flow.
Key Advantages of a Manual Sorting Cabin
• Decent working conditions, an enclosed cabin, properly lit, ventilated and climate-controlled, because manual sorting in a dusty, smelly hall cannot be done well or for long.
• It catches what the machines miss, textiles, hazardous waste, black plastics the optical sensor cannot reliably read, composite packaging: this is where they leave the flow.
• It raises final purity, a human check at the end of the line is the difference between a fraction the buyer accepts and one rejected for contamination.
• Shadow-free lighting, material recognition depends directly on how well the operator can see, and poor or shadowed light dramatically reduces accuracy.
• Filtered air, dust extracted, the ventilation system continuously removes dust and odour and supplies fresh filtered air, which is a health requirement rather than a luxury.
• Considered ergonomics, station height and belt width are calculated so the operator reaches the material without excessive bending or stretching.
Technical Specifications, Manual Sorting Cabin
| Parameter | Configuration |
|---|---|
| Construction | Fully enclosed cabin, thermally and acoustically insulated |
| Lighting | Strong, shadow-free, along the whole belt |
| Ventilation | Continuous dust and odour extraction, filtered air supply |
| Climate control | Air conditioning and heating, stable temperature |
| Work stations | Configurable number, on one or both sides |
| Ergonomics | Height calculated to reduce physical strain |
| Fraction discharge | Dedicated chutes or containers per material |
| Belt speed | Slow and adjustable |
| Protective equipment | Gloves, safety glasses, high-visibility vest, mandatory |
Cabin dimensions, the number of stations and the chute configuration are set from line throughput, from how many fractions are picked by hand and from the space available in the hall.
Applications for the Manual Picking Station
• Final check on fractions, verifying an automatically sorted fraction before baling and sale.
• Removing hazardous waste, pulling batteries, aerosols and other items that have no place among recyclables out of the flow.
• Materials the machines cannot distinguish, black plastic, composite packaging, objects with labels that fool the sensor.
• Partially automated plants, combined with mechanical separation, an efficient solution where labour cost is lower.
• Pre-sorting at the inlet, removing large and hazardous objects before the flow reaches the machines.
How It Works
The cabin is integrated into the automated line, it does not work separately. Once the waste has passed the mechanical stages, pre-shredding, bag opening, screening by trommel or ballistic separator, a targeted stream is directed to the manual sorting area. This stream is deliberately slower than the rest of the line and contains the material that needs a human decision. The belt runs past the work stations, and each operator is trained to look for a particular material type or contaminant. As the belt advances, the operator quickly scans the material, reaches in and removes the items assigned to them. These are placed into chutes, bins or secondary belts leading to separate collection points, for example a container for film and a chute for non-recyclable contaminants. The cleaned stream then continues to the next automatic stages or to baling. The key to a cabin that works well is belt speed: too fast and the operators miss items, too slow and you lose capacity.
Selection Guide
The number of stations is calculated from the throughput reaching the cabin and from how many fractions are picked by hand, not from the total line throughput. An operator has a realistic limit, and overloading them translates directly into lower purity. The second aspect is placement: the cabin usually goes at the end of the line as a final check, but in plants handling very mixed waste a pre-sorting station at the inlet is also justified, for removing large and hazardous objects. The third, and the one most often underestimated: the indoor environment systems. Ventilation and climate control are not optional, because in a dusty, smelly space performance drops quickly and staff turnover becomes the main problem.
Frequently Asked Questions
Do I still need manual sorting if I have an optical sorter and a robot?
Yes, as a final check. There are always materials the automation cannot reliably distinguish, especially black plastics, which reflect poorly in infrared, and composite packaging. There is also hazardous waste, which needs to be removed by someone who understands what they are seeing. The difference is that people stay for difficult decisions, not for volume.
Why not just a simple sorting table?
Because an operator's performance depends directly on the conditions they work in. In poor light they cannot recognise the material, in dust and odour they tire quickly and make mistakes, and in extreme summer or winter temperatures in an unheated hall the pace drops sharply. An enclosed, climate-controlled cabin is not a luxury, it is what separates sorting that works from sorting that only appears to work.
How many work stations do I need?
It is calculated from the throughput actually reaching the cabin and from how many fractions are picked by hand, not from the total line throughput. An overloaded operator misses material, so purity drops and the benefit disappears. We size the cabin from your real flow, not from a general formula.
What belt speed should it run at?
Slow and adjustable. Too fast and operators have no time to recognise and grab objects. Too slow and you lose processing capacity. The optimum is found in the first weeks of operation, with the real operators and the real material, which is why the adjustment matters.
Is the equipment supplied new?
Yes. We supply new units only, made to order for your application, with complete technical documentation.
What maintenance does it need?
Periodic replacement of the air filters, cleaning the ventilation system and the light fittings, checking the climate control installation and maintaining the conveyor and the chutes. The filters are the critical point: a clogged filter cancels out the whole benefit of the cabin.
