Closed Loop Process

A Closed Loop Crushing Process ensures that the exact material (slag) that you send to Harbert’s is crushed and returned to you. At no time is material from another source mixed with your specific material. At no time is an alternate brand of flux, other than yours, mixed with your specific material.

  • Due to the use of our Closed Loop Process, Harbert’s does not accept any material from a source that is not designated to be returned directly back to that source.
  • Harbert’s does not purchase slag from one source to be crushed and sold to another customer.
  • This ensures that our Closed Loop Process can not be breached in any way.
