Stark Resources partners with Optimum sorting

Hasselt, Belgium — Exciting news! STARK and Optimum have joined forces to push the boundaries of mineral processing 

Geoffrey Madderson
 Chief Executive Officer 

We will leverage our collective expertise, with decades of experience in the sensor based sorting.

We are pleased to announce our partnership with Optimum Sorting that has proven expertise in optical sorting on both Food and Non-Food products. Integrating our respective strengths and collaborating closely, we’ll bring even more innovative mineral recovery solutions that will help our customers stay ahead of the curve.

We believe that our new partner brings invaluable knowledge and experience to the table, and we are excited to work with them to continuously develop new and improved sorting technologies. Together, we will continue to push the boundaries of what is possible in mining and mineral processing, and help our customers to achieve even greater success.



Optimum nv was founded in July 2017 by Paul Berghmans and Steve Raskin, together with investment company Pentahold - three partners with years of experience in the development, production and sales of optical sorting machines using sophisticated camera and laser technology. Their ambition: to put a better and reliable alternative on the market as quickly as possible.

Some of the world's most successful companies have started in the proverbial garage. However, no matter how strongly such heroic examples appeal to the imagination, in a rapidly growing and changing sector, starting from scratch isn’t the best option. In order to make a flying start, an acquisition candidate was sought.

Coincidence or predestined? At the time, the Dutch Concept Engineers, who specialized in optical sorting systems for the food industry, were looking for fresh capital and also wanted to attract additional experience, management and new technology, such as laser inspection. The rest is history: Optimum acquired Concept Engineers and opened a new office in Hasselt, Belgium under the Optimum Sorting trade name.

Today, the group has 100 employees spread across branches in Eindhoven (NL), Hasselt (BE), Denver (USA), Turlock (USA) and Chiang Mai (TH). Development and production take place in Hasselt and Eindhoven. Optimum Sorting Inc. provides the sales and service for the American continent from Denver and Turlock. Sales and service for EMEA takes place from Belgium and the Netherlands, and is done in collaboration with local partners.
