Recycling of flexible abrasives

The challenge.

The production of flexible abrasives generates waste in the form of faulty batches, punching waste and offcuts. Until now, production waste has been thermally recycled rather than recycled as material and then landfilled, which means that it is no longer possible to recover the abrasive grains.

The solution.

Together with RWTH Aachen University and an industrial partner, we have developed such a recycling process as part of a project funded by the German Federal Environmental Foundation (DBU).

Recycling solutions, preconditioning, thermal material disintegration, deagglomeration, separation, classification, FEPA-P standard

The recycling process is divided into five sub-steps:

1. preconditioning / comminution to ensure a defined particle size distribution

2. thermal material disintegration of abrasive grain and binder

3. deagglomeration (gentle separation of the abrasive grain/ash agglomerates)

4. separation/sifting (separation of the abrasive grains from the accompanying materials such as minerals and residual waste)

5. classification according to FEPA-P standard

Abrasives made from recycled abrasive grit recovered using this process meet the quality requirements customary in the industry and have comparable abrasive and material properties to conventional abrasives made from primary grit.

Recycling, abrasives, abrasive grain, primary grain

Your advantages at a glance.

Economic advantages

  • Savings in disposal costs compared to waste incineration or landfilling
  • Savings in purchasing costs, as recycled grain is marketed below the original grain price
  • Recycling of self-developed, high-quality abrasive grains

Ecological advantages

  • Material recycling of abrasive waste instead of thermal treatment with subsequent landfilling
  • Saving of primary energy andCO2 equivalents
  • Sustainable solution for abrasive waste containing cryolite
