What are sludge and sediment?
Sludge and sediment are the settled, oily fractions that build up in tanks, oil/sludge separators, pits and IBCs — classified as hazardous waste. They require separate removal, dewatering and processing. IAM pumps them out, dewaters on site where possible and processes them with documentation.

How does it work?
1
Assessment & sampling
We assess the composition of the sediment and determine the right route.
2
Dewatering & pumping
Pumped out and dewatered on site where possible, removed ADR-authorised.
3
Processing & documentation
Processing at certified facilities with watertight chain documentation.
4
Documentation & completion
You receive the full chain and processing documentation, so the chain is demonstrable and audit-proof.
Regulations & certification
Responsibly processed, fully documented
Oily sludge and sediment are hazardous waste and require the right permits and watertight paperwork — from removal through to processing.

Frequently asked questions
Are sludge and sediment hazardous waste?
Yes, oily sludge and sediment are classified as hazardous waste and are removed and processed separately, with watertight documentation.
Can the sediment be dewatered on site?
Where possible we dewater on site, which reduces the volume to be removed and lowers costs.
Is sediment part of the oil-water collection?
Sediment is the settled fraction that remains after removing oil water and is disposed of as a separate stream.
Do you also clean out the separator or pit?
Yes. We pump out and clean separators, sludge traps and pits, and remove both the oily water and the settled sediment in one visit.
Do I receive documentation when sediment is disposed of?
Yes. With every collection you receive watertight chain documentation, so the chain is demonstrably compliant.
