• Greensand moulds are mostly created with silica sand, bentonite and coal dust (sea coal)

  • Coal dust contaminates the greensand with cracking products from seacoal and it causes emissions.(CO, BTEX ..... and complex components, aromatic 

  • In general coal is more and more abandoned for energie production and provides  a bad image to users 

  • We indicate emissions from sea-coal and in consequence  greensand contamination of benzene, toluol and many aromatic components mostly toxid

  • Working without  coal dust increases sand adhesion and mould expansion defects.

  • We can help you to minimise the use of coal dust or other organic additives and apply new developed inorganic  minerals to compensate  coal dust 

  • It is a long process to get away from coal dust in a running foundry process, and casting quality and productivity should not be influenced by the change.

  • Using no or less organic additives in greensand reduces emissions, greensand waste contamination and no CO2 regulations

We have developed inorganic  minerals to compensate / replace   coal dust
