BHS names managing director of Max-AI

Bulk Handling Systems (BHS), Eugene, Oregon, has appointed Matthias Erdmannsdoerfer to serve as the company’s managing director of Max-AI.

Prior to assuming this role, Erdmannsdoerfer served more than six years as president of Nashville, Tennessee-based National Recovery Technologies (NRT), a developer of optical sorting technology and a subsidiary of BHS. In his new position, Erdmannsdoerfer will be responsible for BHS’ Max-AI product line, including sales, business development and product and application development.

“Matthias has been instrumental to the development of both NRT’s technology and its global footprint,” says BHS CEO Steve Miller. “Matthias’ expertise and success working with all of our companies and systems, including with Max from the beginning, will accelerate our deployment of Max.”

Max-AI technology uses artificial intelligence (AI) to recognize materials in a manner similar to how people recognize materials. The company launched Max-AI in 2017 as a tool to power robotic sorters, optical sorters and reporting systems. The company says it will continue to integrate the tool into new and existing equipment at material recovery facilities (MRFs).

Since its inception, more than 50 Max-AI AQC (autonomous quality control) robotic sorters have been sold into quality control applications for fiber and containers.

“[Max-AI] has entirely changed the way we look at processing waste,” Erdmannsdoerfer says. “I’m currently building out Max’s human team to work with me as we continue to help our customers benefit from all that Max is capable of.”
