Disposal Considerations of
Chemical waste generators must determine whether a discarded chemical is classified as hazardous waste.
Additionally, waste generators must consult state and local hazardous waste regulations to ensure complete and accurate classification.
Observe all federal, state and local regulations when disposing of the substance.
Recycle if possible, but if not, then incinerate or treat in a suitable treatment plant.
Steel drums can be cleaned and re-used if in good condition, or recycle as scrap metal.
IBCs can be cleaned and re-used if in good condition, as there will be negligible odour pick up by the plastic.
If not suitable to reuse then either clean out, shred and landfill, if permitted or clean, granulate and recycle the plastic granules.
Do not reuse containers.
Dispose of as unused product.
