Green Waste Sorting

MSS Optical Sorters have what it takes to automatically sort and clean contaminated, pre-shredded green waste streams. Our technology, used in combination with mechanical pre-processing systems (grinding, sizing, air classification, etc.), is applied to remove prohibitive contaminants (plastics, metals) from your green waste automatically, and generates a contaminant-free green waste product for composting or anaerobic digestion.

Ultra-Efficient Separation, Powerful Optical Sorters

There are two main areas in green waste processing facilities where MSS optical sorters are in a position to provide added value for our customers. The automated removal of any plastics and metals are two of the most commonly preferred applications.

CIRRUS PlasticMax

PlasticMax™ provides the most accurate separation of all plastic resins in all types of waste management facilities. All PlasticMax™ optical sorters combine high-resolution NIR, color, and metal sensors to accurately sort a wide variety of materials, using advanced algorithms. Our proprietary MaxSelect™ sequential scanning technology provides the best combination of scan rate, number of wavelengths and NIR wavelength range (up to 2,500nm). The integrated ClearLight™ technology provides the best signal-to-noise ratio of any optical sorter in the industry because MSS doesn’t use gratings or light beam splitters.


FiberMax™ provides operation flexibility and top of the line sensing capabilities to either extract fiber from mixed input streams or separate paper into the various gradesl. The integrated MaxSelect™ technology utilizes patented sequential scanning technology for the highest-definition image possible. ClearLight™ technology provides the best signal-to-noise ratio of any optical sorter in the recycling industry. MSS doesn’t use gratings or light beam splitters, so detectors receive the maximum amount of reflected light possible, allowing for the most accurate detection.


Our longest running sensor-based technology! For over 30 years, we have used our proprietary induction-based metal detection technology in many different applications. The latest generation provides maximum sensitivity at low cost and durability. As a stand-alone unit, the MetalSort™ provides for the removal of metal contaminants (ferrous, non-ferrous and stainless) at high efficiency.
