List of Disposal Codes

Also see our list of Recovery Codes

D1 Landfill


Deposit into or onto land, (e.g. landfill, etc.) - deposit of overburden, waste rock and tailings on heaps in the extractive industry.

D2 Land treatment


Land treatment, (e.g. biodegradation of liquid or sludgy discards in soils, etc.) - spreading of waste on land, often followed by the incorporation of the waste into the soil, which does not result in benefit to agriculture or other ecological improvements. Generally applies to non-hazardous sludge and liquid wastes, e.g. disposal of dredging sludge.


D3 Injection


Deep injection, (e.g. injection of pumpable discards into wells, salt domes of naturally occurring repositories, etc.) - injection of waste into natural and artificial cavities (e.g. salt domes, wells, mines), and porous formations of rock not covered by Directive 1999/31/EC.

D4 Surface impoundment

Surface impoundment, (e.g. placement of liquid or sludge discards into pits, ponds or lagoons, etc.) - the deposit of waste in natural or engineered ponds, pits or lagoons (impoundment), which is the predominant method for the management of tailings in mining operations; impoundment of dredging sludge.

D5 Engineered landfill


Specially engineered landfill, (e.g. placement into lined discrete cells which are capped and isolated from one another and the environment, etc.)  landfills for inert waste, non-hazardous waste and hazardous waste above ground.

 D6 Release to waters


Release into a water body except seas/oceans - deposit of non-hazardous dredging sludge and other non-hazardous sludge in surface water including the bed
and the subsoil.


D7 Release to sea


Release into seas/oceans including sea-bed insertion - discharge of waste at sea in accordance with the OSPAR Convention (e.g. discharge of fish processing waste and inert materials of natural origin).


D8 Biological treatment


Biological treatment not specified elsewhere in this Annex which results in final compounds or mixtures which are discarded by means of any of the operations numbered D1- D12 -biological-wastes, if followed by disposal.


D9 Physico chemical treatment


Physico chemical treatment not specified elsewhere in this Annex which results in final compounds or mixtures which are discarded by means of any of the operations numbered D1-D12 (e.g. evaporation, drying, calcination, neutralization, precipitation, etc.) physico-chemical treatment is typically deployed for: il/water mixtures; neutral aqueous organics and inorganics (production specific waste water, leachate, etc.); cyanides; acids and alkalis. Typical treatment steps are detoxification (oxidation/reduction), precipitation, neutralisation, emulsion separation, immobilisation, electrolysis and osmosis.


D10 Incineration on land


Incineration on land - municipal solid waste incineration plants for incineration of MSW, hazardous waste, sewage sludge, clinical waste, animal carcasses.


(D11) (Incineration at sea)


(Incineration at sea) This operation is prohibited by EU legislation and international conventions.


D12 Permanent storage


Permanent storage (e.g. emplacement of containers in a mine, etc.) - landfills for the underground storage of waste.


D13 Blending or mixing prior to submission to any of the operations numbered D1-D12

Blending or mixing prior to submission to any of the operations numbered D1-D12 landfilling; mixing and blending of waste (e.g. mixing of similar wastes from different waste generators); solidification.


D14 Repackaging prior to submission to any of the operations numbered D1-D13

Repackaging prior to submission to any of the operations numbered D1-D13

D15 Storage pending any of the operations numbered D1-D14


Storage pending any of the operations numbered D1-D14 Does not apply to storage of waste prior to collection at the site at which it was generated. Temporary storage of waste prior to disposal is limited to a period of <1 year. Otherwise the provisions of the Landfill Directive apply (Directive 1999/31/EC, Article 2(g)).
