MSS has been building sorting equipment for more than fifty years. The company started in 1973 when a group of engineers began working on better ways to separate metals. From those early machines, MSS grew into one of the first names in optical sorting for recycling and plastics.

Over time, the company added new tools. BottleSort® came out in the early 1990s to handle plastic bottles by type and color. Later, MSS built camera-based systems that could pick out shape, color, and even fine defects. They also kept refining their metal sorters with induction and eddy current technology. Today, artificial intelligence is built into many of their units, letting the machines adapt to changing material streams without constant human adjustment.

MSS is part of CP Group and still designs and builds its own sensors and software. That control over design is part of why the equipment has a long track record in tough environments. In 2023, MSS marked its 50th year in the business.

What They Build

MSS makes a full range of sorting machines:

• Optical sorters that separate plastics by resin type and color.
• Camera systems for fine sorting and quality control.
• Metal detection and separation equipment.
• Machines built for film, flexible packaging, and paper.
• Sorting units with AI and machine learning to handle mixed or unpredictable feed.

Why It Matters for Plastics Wash Lines

For anyone running a plastics wash line, clean input and pure output make a big difference. MSS systems can pull out metals, films, and off-grade plastics before washing, which helps reduce wear and energy use. After washing, their machines can refine material even further, sorting by polymer or color so the final product has higher value.

Because the equipment runs fast and is built to last, it helps processors move more material with fewer stoppages.
