- “incineration plant”: each technical establishment used for the incineration of waste by oxidation, including pre-treatment, pyrolysis or other thermal treatment processes (for example, the plasma process), to the extent the products of this are incinerated with or without the recovery of the incineration heat produced. This definition covers the premises and the whole installation with the incinerator, the systems for the supply of waste, fuel and air, provisions for waste gas and waste water treatment as well as the equipment and systems for the regulation of the incineration process and for the continuous registering and monitoring of the incineration conditions.






- “ash”: the ash from the incineration of waste, including bottom ash and grate ash, with the exception of fly ash;

- “fly ash”: the fine ash from the incineration of the waste, which is accumulated during the dedusting or other treatment of waste gases;

- “landfill”: means a waste disposal site for the deposit of the waste onto or into the soil (i.e. underground), including:


internal waste disposal sites (i.e. landfill where a producer of waste is carrying out its own waste disposal at the place of production), and


a permanent site (i.e. more than one year) which is used for temporary storage of waste, but excluding:


facilities where waste is unloaded in order to permit its preparation for further transport for recovery, treatment or disposal elsewhere, and


storage of waste prior to recovery or treatment for a period less than three years as a general rule, or


storage of waste prior to disposal for a period less than one year;

- “mono-landfill”: any landfill where a certain waste originating in large quantities is separately deposited;

- “landfill section”: numbered part of the total available landfill volume;

- “landfill zone”: zone in the landfill where the deposit and compression activities take place and where the waste does not have to be covered in the course of the working day;

- “working face”: width of the landfill zone where the unloading activities for waste take place;

- “barrier layer”: layer on the bottom and walls of the landfill which is to prevent leachate from seeping through to the soil and groundwater;

- “sealant layer”: layer applied on top of a landfill section where the depositing activities have definitively been completed to prevent the penetration of water into the deposited waste;

- “cap”: layer applied on a landfill section on top of the sealant layer upon the definitive completion of the depositing activities;

- “leachate”: any liquid percolating through the deposited waste and emitted from or contained within a landfill;

- “semi-solid” (in relation to sludges): sufficiently dewatered so that the accessibility to and the stability of the landfill are never in jeopardy;

- “solidification”: physicochemical treatment whereby dangerous substances in the waste are immobilised by chemical or physicochemical rearrangement;

- “public landfill”: any landfill which by virtue of the Waste Materials Plan has a public function;

- “landfill dikes”: dikes that skirt the landfill;

“dike slopes”: inclined sections (slopes) of the dikes;

inner slope: slope on the side where depositing takes place;

outer slope: slope on the side of the surrounding parcels;

“dike crown”: top horizontal part of the dike between inner and outer slope;

- “operational phase”: period during which the landfill is operated, including the final finishing work on the landfill;

- “after-care phase”: period following the operational phase;

- “inert waste”: waste that does not undergo any significant physical, chemical or biological transformations. Inert waste will not dissolve, burn or otherwise physically or chemically react, biodegrade or adversely affect other matter with which it comes into contact in a way likely to give rise to environmental pollution or harm human health. The total leachability and pollutant content of the waste and the ecotoxicity of the leachate must be insignificant, and in particular may not endanger the quality of surface water and/or groundwater.

- “landfill gas”: all the gases generated from the landfilled waste;

- “eluate”: the solution obtained by a laboratory leaching test;
