Fewer pollutants in used sand

The restrictions placed on foundry residues sent to landfill have recently become much stricter. On the one hand, landfill space is becoming increasingly scarce. On the other, the costs for foundries are rising due to stricter legal requirements. 

With this in mind, HA has developed a low-organic Cold-Box binder system with a phenol (monomer) content <1.0%. The low-phenol binder system helps to reduce foundries’ key emission parameters. The binder system also allows foundries to reduce the pollution load of their used sand (phenol index). By reducing the proportion of free phenol and formaldehyde, the used sand is more suited for being sent to landfill.
