06 09 02 Phosphorous slag

EWC / List of Waste code · Last checked 21 October 2026 · Applies across the UK (England, Wales, Scotland and Northern Ireland)

Not hazardous Absolute non-hazardous entry

Official description: “phosphorous slag”

Where it sits: chapter 06 (wastes from inorganic chemical processes), section 06 09 (wastes from the MFSU of phosphorous chemicals and phosphorous chemical processes).

What the hazard status means

Waste that matches this description is not hazardous waste. Check that nothing hazardous has been mixed in: a load that contains hazardous waste needs a different code.

Using this code

Write the code on the paperwork when waste is passed on: a waste transfer note for non-hazardous waste, or a consignment note for hazardous waste (called special waste in Scotland).
Choose the code from where the waste came from first (the chapter), then what it is. If a load is mixed, you may need more than one code.
The waste must go to a site whose permit allows that code. A registered carrier can tell you which codes they accept: check a waste carrier.
Businesses have a duty of care to describe their waste correctly.

Other codes in section 06 09

06 09 03* Calcium-based reaction wastes containing or contaminated with hazardous substances Hazardous
06 09 04 Calcium-based reaction wastes other than those mentioned in 06 09 03 Not hazardous
06 09 99 Wastes not otherwise specified Not hazardous

This page explains the code in plain English. It is not a classification of your waste. The official List of Waste and the classification guidance decide which code applies, and you are responsible for the code you use.
