Disposal code

D12: Permanent storage

Waste is stored for good, with no plan to move it on. Containers placed in a mine are the annex's example.

The legal wording

Permanent storage (e.g. emplacement of containers in a mine, etc.)

From Annex I to the Waste Framework Directive, which the Digital Waste Tracking (England) Regulations 2026 point to for every D code.

Disposal in the waste hierarchy

D12 is a disposal operation, the last step in the waste hierarchy. A business that passes waste on has to take the reasonable steps open to it to put prevention, re-use, recycling and other recovery first.

On a Digital Waste Tracking receipt

For each EWC code (the six-digit code from the List of Wastes that says what a waste is) on a receipt, the site that takes the waste in records the D code or the R code, or both, for what it will do with it, and the weight each code covers.
