Hazardous property code
HP 14 Ecotoxic
Waste that poses risks to the environment, potentially affecting ecosystems.
HP 14 covers waste that presents immediate or delayed risks to one or more parts of the environment. It is the outlier among the hazard properties: every other HP describes harm to people or animals, while HP 14 is about ecosystems — water, soil and the organisms in them.
It is recorded on the consignment note as a hazard code. Whether it applies to a load is a WM3 assessment of the substances actually present and their concentrations, and it is the producer who carries that duty.

EWC codes that commonly carry this hazard property
15 of 142 entries from the UK List of Wastes.
These are EWC entries that typically carry this hazard property, not a determination that any particular load does. Under WM3, whether a hazard property applies depends on the substances actually present and their concentrations — the producer is responsible for assessing each consignment.
- 01 05 05oil-containing drilling muds and wasteshazardousOil-containing drilling muds — residual mineral oils are flammable and ecotoxic.
- 03 02 01non-halogenated organic wood preservativeshazardousNon-halogenated organic wood preservatives — biocidal actives are acutely toxic and ecotoxic.
- 03 02 02organochlorinated wood preservativeshazardousOrganochlorinated wood preservatives (e.g. pentachlorophenol) — acutely toxic, carcinogenic and ecotoxic; PCP is a listed POP.
- 03 02 03organometallic wood preservativeshazardousOrganometallic wood preservatives (e.g. tributyltin, organo-copper) — acutely toxic and ecotoxic.

Recording HP 14 on real paperwork?
Waste carrying HP 14 is hazardous, so it moves on a Hazardous Waste Consignment Note rather than a standard Waste Transfer Note. Our free generator produces a compliant PDF in under a minute.
