Recycling of residual waste from power plants

Our residual waste material recycling plants enable the targeted recycling of residual waste material from power plants. This includes first and foremost:

  • Filter ash, fly ash
  • Wet ash, bottom ash and slag
  • FGD gypsum
  • The crude ashes available to us and the materials produced in our recycling processes are used in multiple applications in various fields:
  • direct backfilling or backfilling of thick matter in underground cavities
  • road construction material
  • material for the conditioning of liquid and highly viscous substances

The consistent high quality of all products obtained from our processes is ensured by strict quality management.

Depending on our criteria on the acceptance of waste materials, we are able to accept the following residual waste from power plants and recycle them in our treatment plants:
