Our decades of experience have taught us that our machinery and consumables go hand in hand with key support services. These include our eco-service: the collection of your vibratory finishing slurries.
In this way, we provide a sustainable Service not only for you, but also for the environment. Please feel free to contact us if you would like further information, a no-obligation quote or a consultation.


The recirculation system allows you to reuse your process water repeatedly during mass finishing over a specific period. This recirculation system works particularly efficiently when the parameters are checked regularly and the process is adjusted accordingly. Our laboratory would be happy to assist you with this – simply get in touch!
The parameters are also crucial in flow-through systems, where the treated water is discharged into the sewerage system. This is because strict, legally prescribed limit values must be adhered to. Our laboratory will be happy to analyse your effluent parameters and provide expert advice should you need to take appropriate measures.

Mass finishing produces sludge that must be disposed of properly. For you, this means high costs and a significant administrative burden due to regulatory requirements involving complicated declarations. That is why we have made it our mission to support you in this process whilst also contributing to environmental protection and sustainability – entirely in line with the guiding principle ‘Recycling takes precedence over disposal’ as set out in Sections 4 and 5 of the KrW-/AbfG (Circular Economy and Waste Management Act), which sets out the fundamental obligations of the circular economy.
A service for our customers in Germany: we take back your vibratory finishing sludge, which is produced through the use of our consumables, in a straightforward manner and recycle it in an environmentally sound way. For you, transporting the sludge to our plant in Haan does not require a permit, as we are registered with the relevant authority as the waste producer.
