Reference screening machines for Municipal solid waste
This recycling project in Sweden shows the positive, important influence that the right Classification screening has on the overall sorting performance of the plant.
SPALECK screening machines process municipal waste in such a way that downstream sorting systems can exploit their full potential.
One of the most modern sorting plants for Municipal Solid Waste (MSW) in Europe – designed for fully automated operation with high throughputs and maximum recovery of recyclable materials.

The Vibrating screens Classify the Municipal solid waste into the defined Particle sizes. The aim is to provide the sorters with optimum input material.
Mixed household waste is one of the most challenging Material flows in recycling. Composition, moisture and particle sizes vary greatly and require high-performance and reliable recycling technology.
Several challenges need to be solved for efficient sorting:
The new plant in Linköping was developed with clear objectives in mind:
The video shows the concept of the system and the interaction of the process steps – and the influence that classification by Particle size has on sorting performance.

TRANSFERABILITY for your preparation
The Tekniska verken project example shows the central role that sorting plays in the Recycling process. Precise sorting of the Material flow according to material size improves the efficiency, Throughput and sorting quality of the downstream Magnetic sorters, eddy current sorters and NIR Sorting Machines/Sorters.
The solutions used can be transferred to many other applications:
Would you like to find out more about our screening machines for Municipal solid waste and municipal waste? Or do you have a specific project in mind? Then let’s talk about your material and your MSW processing. I would be happy to show you further references and applications.
In practice, existing MSW recycling plants are regularly optimized through adjustments. The aim is to continually optimize the sorting process. For us as a Screening machine manufacturer, what counts here is the close, partnership-based exchange with our customers. For example, we pass on our latest technical developments in Screening technology to our customers. In addition, our screening machines are highly customizable thanks to the ModularDESIGN+ concept. You can see exactly how this works in this video “How the right screening technology improves sorting performance in MSW recycling plants.”: https://youtu.be/8IE1C85Ca4c
The design of an MSW recycling plant is very individual. Among other things, this is determined by the material composition, particle size distribution, density and moisture of the material. The required throughput and the recycling targets of the processor are also important. These factors influence the selection of shredding, Screening technology and sorting systems as well as the overall process control. Test centers such as the SPALECK Test Center help with the selection of screening technology, where recycling companies can get to know the material in detail through extensive screening tests and determine the optimum setting for the screening technology even before the system is planned. The results of these screening tests are also very helpful for determining and designing the downstream sorting technology.
Precise classification of the material by size improves the Efficiency of MSW recycling plants by increasing sorting accuracy and recovery rates. More recyclable materials can be recovered thanks to defined grain bands. At the same time, downstream units are relieved, which reduces maintenance costs and downtimes.
Different screening technologies are used in MSW recycling plants. These include recycling screens for classification, such as the SPALECK Recyclable Material Screens or Flip-flow screens. Special screening technology helps not only to sort the material by size, but also to remove unwanted long parts from the target grain.
Fines are critical in the MSW material flow because they have a negative impact on sorting performance. They attach themselves to larger particles or spread uncontrollably in the material flow. This results in carryover between the fractions and makes detection by sensor-based systems more difficult. If this fine fraction were not screened, e.g. with the help of SPALECK Flip-flow screens, the cleaning effort on the sorting devices would also increase and their efficiency would decrease.
Mixed municipal waste is processed in an MSW recycling plant. This includes everything that is disposed of by private households as Municipal Solid Waste. This includes, for example, plastics, metals, paper and organic components. The material is generally very heterogeneous and places high demands on processing and sorting.
