This optical Recycling Sorting Machine is a new recycling technology that design and made by Peaks-eco, we have cooperated with each other for long times.

As the global pioneer in sensor-based sorting, our sorting technology continues to dynamically drive the development of increasingly better and newer sensors. Customers benefit from exceptional material detection that lead to optimized product yield.

Peaks-eco Sorting Solutions offers an extensive and exclusive range of advanced detection technologies for identifying and separating a wide variety of materials. Pioneers in the automation of waste sorting, Peaks Sorting's innovative sensors identify and recover recyclable materials accurately and profitably and with dramatic cost savings.

How does NIR Optical Sorting System Work?

Optical Recycling Sorting Machine recognizes and sorts Organic Material by analyzing the reflected NIR (Near Infra Red) lights from the surface of the material. Every organic compound absorbs light of its own wavelength depending on the molecular nature of the materials. Accordingly, the machine provides a function to recognize the materials by optically analyzing the wavelength of the reflecting light, and it converts the light value into an electric value by making use of a photo diode. A camera detects the light reflecting from the waste stream on the conveyor on which the light from a halogen lamp shines. The detected light is converted into an electric signal by a spectroscope, and then into computer data. The computer analyzes the data to identify the materials in the waste stream. The computer uses compressed air to move the wastes to defined locations after precisely identifying the materials in the waste stream. Optical Sorting Machine sorts wooden materials, plastics of different kinds, paper, cardboard, ferrous and nonferrous metals and can separate them according to the material and color through the advanced optical technology using near infrared (NIR), mid-infrared (MIR) and visible light. One of the advantages of the Optical Sorting Machine is the material recognition adjustment when the waste is physically composed of various materials just by adjusting the program. For example, you can pick out only PET by setting the program to hardly recognize or not to recognize PE cap or PP label of a PET bottle.
