Eco-friendly metal separation in lignin biopolymer production: a two-stage waste-free solution (case study)

The production of lignin biopolymers places high demands not only on process quality, but also on environmental performance and sustainability. Metal impurities that enter the liquid medium during production had to be removed reliably – while also avoiding unnecessary waste that would burden the environment.

The goal was clear:

  • separate metals from the process, but do not discharge them into waste together with the rinse liquid.

Two-stage separation: a smart solution that makes sense

The answer was a two-stage magnetic separation combining:

  • MSP-AC 50 N SHARK automatic magnetic filter
  • MVS-LUX 300 N magnetic discharge roller

This system works as a closed, environmentally friendly separation loop.

Stage 1 – automatic metal separation in the MSP-AC 50 N SHARK magnetic filter

In the first step, metal impurities are captured by the MSP-AC 50 N SHARK automatic magnetic filter, designed for pressurised pipelines and liquid mixtures. The filter runs continuously and without operator intervention.

During automatic cleaning, the captured metals are:

  • rinsed with water,
  • released from the magnetic rods,
  • prepared for the next separation step.

And this is where the crucial environmental difference comes in.

Stage 2 – no waste, only clean metals thanks to MVS-LUX 300 N

Instead of being discharged into waste together with the rinse liquid, the metals are conveyed by compressed air to a separation vessel fitted with the MVS-LUX 300 N magnetic discharge roller.

This roller:

  • is fitted with the strongest neodymium magnets,
  • separates metal particles from the rinse liquid,
  • ensures that the outlet contains almost dry metals.

As a result, the metals do not end up in waste, but where they belong – ready for further use or environmentally responsible disposal.

Results: a clean process and a truly eco-friendly solution

After commissioning the system, the customer recorded:

  • reliable separation of metals from the production process,
  • zero metal leakage into the waste liquid,
  • a significantly greener operation,
  • the ability to handle metal waste separately,
  • stable, automatic and unattended operation of the technology.

Why this solution is truly ECO

  • metals are not discharged into waste,
  • the rinse liquid is not contaminated with metal particles,
  • waste load is minimised,
  • metal waste is separated, dry and controllable.

It’s not just about separation. It’s about a responsible approach to production and the environment.

Conclusion

The combination of the MSP-AC 50 N SHARK magnetic filter and the MVS-LUX 300 N magnetic discharge roller shows that even demanding industrial production can be clean, efficient and eco-friendly at the same time.

This two-stage metal separation does not only solve a technological problem – it delivers a real environmental benefit without compromise.

This is separation that thinks ahead.
