Biography Jan Groothoff

• Jan Groothoff (60 years of age) is a Dutch mining engineer (University of Delft, The Netherlands) and served 17 years in one of the largest steel slag processing companies in the world, Heckett Multiserv. During this period
  he managed as regional director and local manager large slag recycling operations in the Netherlands (Corus), Luxemburg (Arbed), Scandinavia (Fundia, SSAB, Nirosta), Russia (MMK), Slovakia (USX) and Czech Republic (Nova Hut). These operations were mostly at carbon steel producers.
• At the Corus works in IJmuiden he developed the licensed coolant scrap production, which converts slittings from the hot and cold rolling mills into high quality coolant nodules for the vacuum degasser.
• In 2003 he started his own consultancy company RecCo BV, specialized in the recovery of ferrous and non-ferrous metals from waste streams. RecCo BV worked together with a client in the Netherlands, which has a 20 year experience in recovery of non-ferro mix metals from shredder waste and incinerator slag. In their works, hightech technologies are used to recover and seperate the non-ferrous mixed metals into seperate base metals. One of these techniques is sensor separation. A semi-mobile and a fully mobile sensor machine were developed to carry out extensive pilot plant test to recover stainless steel scrap from slag streams.
• In 2005 S3R BV was then established to further develop, market and sell turnkey dry recycling proposals to potential clients in the stainless steel/non-ferro producing industry.
• Mr. Jan Groothoff is the managing director of S3R BV, with Recco BV as major shareholder. He developed for S3R BV the now license applied for Recco-Marilyn dry recycling concept for the recovery of stainless steel/ferro alloys from slag.
• First project was sold in 2005 to a Taiwanese customer for a 75 t/hr single shift/day plant.
• Second project was sold february 2006 to Tisco (China) for a 150 t/hr 2 shift/day plant in taiyuan.
