7A34
- Low Activity Liquids (excluding Hg)
Contaminated liquids originate from four main sources: cutting oil from machining operations, lubrication oils, spent oil from vacuum pumps and sludge from liquid effluent treatment. Machining operations provide the most heavily contaminated wastes from the presence of swarf, whilst the other processes contain fine particulate. Other liquids include coolants, chemicals and chiller solutions.

- Pyrochemical Wastes
The waste are generated from processes used to refine metals.
