Waste disposal
SOP for the disposal of non-halogenated solvent waste
generated in the School of Chemistry and Chemical Biology:
1. Collect a 10L non-halogenated solvent waste container
from Chemistry stores.
2. This container will have a numbered tag and a large red
diamond with flame (see photograph below).
3. Ensure the container tag is logged in by a Stores officer.
4. Use the waste container to collect non-halogenated
solvent waste.
5. Fill the waste container to 90% capacity.
6. Bring the waste container to stores and place it on the
appropriate pallet, lining it up as instructed on the pallet.
All waste containers returned to Chemistry Stores must have
the correct label and tag, containers without appropriate
labels and tags will not be accepted.

SOP for the disposal of aqueous extraction from organic synthesis
generated in the School of Chemistry and Chemical Biology:
1.Contact the School Safety advisor to ensure the components of the
aqueous extractions are compatible with the waste stream.
2. Collect a 10L non-regulated aqueous waste container from stores.
3. This container will have a numbered tag and will be labelled “NON
REGULATED MATERIAL – AQUEOUS WASTE” (see photograph below).
4. Ensure the container tag is logged in by a Stores officer.
5. Use the waste container to collect aqueous extractions.
6. Fill the waste container to 90% capacity.
7. Ensure the contents are pH neutral.
8. Bring the waste container to stores and place it on the appropriate
pallet, lining it up as instructed on the pallet.
SOP for the disposal of chemically contaminated glass and sharps
generated in the School of Chemistry and Chemical Biology:
1. Collect a chemically contaminated glass and sharps bin from
Chemistry Stores.
2. Carefully place all chemically contaminated glass and sharps for
disposal into this bin.
3. When the bin is ¾ full; close and seal the bin.
4. Return the bin to Chemistry Stores and place on the designated pallet.
SOP for the disposal of chemically contaminated laboratory waste
1. Place the waste in the chemically contaminated laboratory waste bin (see photograph below).
2. When the bin is 2/3 full; close and seal the bin.
3. Bring the bin to Chemistry Stores and carefully place beside the chemical waste drums.
