Sorting Plants for Commercial Waste

Commercial waste consists of a wide range of different products, substances and materials with variable volumes and a rather high density. This means that high demands are placed on the machinery used.
This poses no problem, thanks to our extremely high quality standards.

STADLER experience

“Almost twenty years of experience in commercial waste sorting – 15 plants constructed worldwide – makes us an expert in this segment.”

Material properties

Our commercial waste sorting plants separate all substances or products that are generated in trade and industry. With a density of approx. 150 kg/m³, commercial waste is relatively heavy.

Example process description

The process starts with material dosing via an infeed hopper or metering drum. Following initial shredding, the material is separated into different grain sizes by a trommel screen, and then into different shapes by ballistic separators (flat [2D], rolling [3D], screening). In addition, large flat films are separated from the material flows by windshifter or trommel separator. This significantly improves subsequent sorting using near infrared technology (NIR).
In combination with the magnetic and eddy current process, the desired high output qualities are achieved. If required, the fraction purity can be optimised through manual sorting. Finally, the separated fractions are collected in product bunkers or boxes and baled to reduce volume for transport.
