State-of-the-art sorting is the goal of many recycling companies today. The topic of NIR is becoming increasingly important. The aim is to use near-infrared spectroscopy to further improve the sorting of different materials.
Our team would be happy to advise you on NIR sorting and how SPALECK technology can help you get the most out of your NIR system.
Sensor sorting with near-infrared technology is suitable for a wide range of recycling materials. NIR sorting systems are widely used today. This is because they help to increase the accuracy and efficiency of recycling. Common areas of application are almost all types of recycled materials.
These include, among others:
We would be happy to advise you on how to optimize the recycling rate of your materials using NIR sorting and our SPALECK screening technology.
We also offer to test your materials in our TestCenter. Of course, you can further process the materials prepared in this way in the test centers of the manufacturers of NIR sorting systems. This is our daily practice. We will be happy to help you with this.
Simply send us a photo of your material and the key details about the project, and we’ll get back to you right away.

More Information
NIR sorting systems are fully automated sorting systems that sort a wide variety of materials according to their near-infrared spectrum. They belong to the group of sensor-based sorting systems. In recycling, it is a modern and established technique for reliably sorting materials according to their molecular composition. This depends largely on the interaction of the recycling technologies used. For example, screening machines, feed hoppers and vibratory feeders carry out elementary preparatory work so that NIR sorting can be carried out economically.
In NIR sorting, the recycling material is fed to the NIR sorting plant via a conveyor belt. A light source installed above the conveyor belt irradiates the various recyclable materials with infrared light. This physical analysis technique uses infrared rays in the 760 – 2500 nm range. Depending on the material, more or less of the wavelengths are reflected. The NIR sorting device assigns the individual piece of material to a specific material class based precisely on this information about which wavelengths are absorbed or reflected.

More InformationThe aim and necessity of recycling is to process large volume flows in the best possible way. This is necessary so that recycling can be carried out economically. Thanks to the technical design and the screening machines and vibratory feeders specially designed for your recycling process, your NIR sorting machines are fed very consistently. This enables very high throughputs. At the same time, it enables the materials to be separated so that the NIR technology can detect them optimally. This gives you a monolayer with a feed width matched to the NIR device. This ensures optimal feeding and excellent separation results.
