Silica Waste

Silica Waste

Silica gel is commonly used in synthetic laboratories for column chromatography. The waste silica is typically contaminated with organic solvents and research chemicals and is collected for disposal by an external waste contractor. Whenever possible, silica waste should be collected in empty 5-litre solvent containers.

Disposal Procedure

When the container is full:

  • Replace and tighten the lid of the container.
  • Wipe down the outside of the container to ensure it is clean and free of silica dust.
  • Add a “waste silica” label to the bottle, ensuring the research group name is added
    (labels can be obtained from stores).
  • Place the silica bottles in the special waste store.
    E-mail [email protected] to arrange access to the special waste store.
