Reusing MWF instead of recycling

As environmentally friendly citizens, we recycle. But when it comes to process fluid, recycling can be a waste of financial and environmental resources.

Everyone that is working with water based process fluids know that they need to be continually topped up with concentrate and water, because the liquid is lost by evaporation or comply with chips and produced components. To increase the value of the metal, the process fluid is often centrifuged from the chips and then sent to destruction, but it can still be put in use.

What are the benefits?

Destruction of process fluid is a major cost item, and to re-use a larger portion will also mean that you don´t have to buy the same amount of concentrate. In addition, most companies' today aim to reduce the environmental impact and that usually include a reduced amount of waste.

Why isn’t it done more often?

Many feel uncertain about the quality and think it’s safer to send the fluid to destruction, but with careful monitoring and a proven method, you can feel safe. Just because you've always done things a certain way doesn’t mean it’s the best way.

How to recycle safely?

  1. Focus on the fluids with the best quality. Fluids that have been standing still for a long time may not be able to save. Ensure that in the future, the fluids that’s going to be reused is quickly taken care of.
  2. Separate the process fluid from particles, tramp oil, bacteria and mold to a level at least equal to the fluid in the machines.
  3. Top up with new concentrate and additives if necessary.
  4. Test the fluid in a suitable single machine and evaluate the results during a trial period.
  5. Implement the recycling process in most of the systems and automate as much as possible. It’s often more profitable with larger volumes.
  6. As always, it’s important to regularly check the fluids’ quality.
