About us

One-stop-shop for recycling and bulk material handling systems

Bulk material handling, production, and recycling systems: we design, develop, deliver, install, and maintain a wide variety of machinery, from single units to complete turnkey installations. With our expertise and experience, we have been supplying many industries in the field of recycling and handling of dry bulk goods. This experience leads us to aim for higher goals every year, to keep developing, and to help our clients meet their stringent demands. NM Heilig is proud to offer installations with:
  • over 98% continuous operation, so hardly any downtime for maintenance
  • 90%-99% of recovery and purity rates in plastic recycling thanks to optical sorting (NIR)
  • over 6000 ton/hour capacities (depending on bulk handling conveyance, materials, and density)
  • exact conveying capacity measurements up to +/- 0,5%
We pursue these numbers for every unit and every installation we supply. Not for high-capacity and complex systems, but also standard applications demonstrating a strong and efficient solution.

It all started in 1978 when N.M. Heilig B.V. was founded by Nicolaas Maria Heilig. The company started out with one welding machine, followed by the maintenance and production of various machinery. These services were the cause of an unrivaled success and, during the years, lead to specialization and acquisition of related businesses in machinery and installations for the bulk handling and recycling industry. In fulfilling our mission to offer our clients full-service in engineering, developing, manufacturing, and installing, we have extended the Heilig Group to what it is today. A group formed by individual companies offering a whole concept of solutions in recycling, waste management, bulk handling, wood processing, heat exchanging, industrial mixing, and electrotechnology. The Heilig Group companies, located in different European countries, compose a powerful and leading conglomerate serving customers all over the world.
