Solid waste – SW: solid waste refers to solid objects, solid substances, materials or refuse which are useless, are intended to be disposed of, or require to be disposed of;
Non-hazardous solid waste - NHSW: means waste, that doesn’t represent danger for human health, animals or plants respectively like general waste from households, markets, public places, restaurants, guesthouses, hotels, parks, commercial facilities, etc. - see annex I.


Hazardous solid waste - HSW: hazardous waste refers to radioactivity substances, explosive substances, toxic substances, inflammable substances, pathogenic substances, irritating substances, corrosive substances, oxidizing substances, or other chemical substances which may cause the danger to human (health) and animal or damage plants, public property and the environment. The hazardous waste may be generated from dwelling houses, industries, agricultural activities, business and service activities, mining,....etc. The type of hazardous waste is listed in the Annex of this sub-decree no 36 ANRK.BK dated 27,
April1999. on the solid waste management.


Municipal solid waste - MSW: MSW is mainly constituted of household waste and household like waste discarded from dwellings, public buildings, factories, markets, hotels, business buildings, restaurants, transport facilities, recreation sites, etc;


Household waste: household waste is part of solid waste predominantly form private household.


Medical waste-MW: refers to waste, which is generated from all medical facilities and activities.


Market waste: waste generated from markets.


Slaughterhouse waste: waste generated from slaughterhouses.


Agriculture waste: waste generated from planting or harvesting of crops, trimming or pruning of plants, and wastes or

run-off materials from farms or fields.


Garden waste: refers to lawn mowing, leaves, branch/twigs of trees, etc.


Industrial waste: waste generated in industries, factories, etc.


Construction & demolition waste: construction debris, excavated materials and road/bridge construction debris, etc.


Laboratory waste: waste in laboratories.


Street sweeping: waste generated during street cleaning.


Kitchen waste: food scraps from preparation of meals and related leftovers after meals, such as vegetable, fruit, meat, fish, bones, skins, feathers, egg shells, including pieces of paper and cardboard made dirty because of contact with the food (e.g. wrapping materials).


Bio-waste: refers to kitchen waste (food scraps) be it of animal or vegetal origin and green waste, which can be biodegraded.


Biodegradable waste: means any waste that is capable of undergoing anaerobic or aerobic decomposition, such as food left-over, green waste, paper and paperboard.


Packaging waste: waste arising from used packaging, disposed of by final users or waste producers.


Recyclable waste: waste materials that can be reused or processed into intermediate or new products.

Definition 12 / 35


Sewage Sludge: refers to solid or semi-solid material generated by sedimentation or biological treatment at municipal or similar industrial wastewater treatment plants including sludge that has been de-watered or dried or treated in any other form.


Landfill: means a waste disposal facility for disposal of waste not capable of further processing/recycling, onto land or into land.


Landfill leachate: means any liquid percolating through the deposited waste and emitted from as well as contained within a landfill.


Landfill gas: all gases, which are generated from the landfilled waste through spontaneous
or induced decomposition.


Contaminated water: all water at a disposal facility that got in contact with waste.


Compost: refers to the final product of composting. It is basically a soil improver (or a peat substitute in potting mixes) but also provides for a supply of nutrients, thereby replacing chemical fertilizer in croplands, it makes soil fertile and improves the soil structure, biological functions and bio-diversity and water retention capacity.


Composting: biological transformation process under proper aerobic conditions, that partly degrades and partly transforms organic matter into humus-like substances; the process evolves through a thermopile phase (whereby sanitization of materials is ensured) and leads to a stabilized material, where residual fermentation is reduced to the least. Composting takes place in presence of oxygen.


Dig estate: solid or semi-solid residues after anaerobic digestion.


Anaerobic digestion: biological transformation process taking place in the absence of oxygen that generates biogas (including methane) and a residue that may be used as a feedstock for a subsequent composting step. or used directly in crops


State of the art: means proper technical approach and/or technology at present.


Waste treatment facilities: means sites hosting any physical, thermal, chemical or biological processes, including sorting, that change the characteristics of the waste in order to reduce its volume or hazardous nature, facilitate its handling or enhance recycling/recovery.


Dumping areas: located on the landfill with underground installation in which waste can be deposited without limit of time.


Intermediate storage area: intermediate storage shall be understood to be a fixed waste management installation in which waste is received, prepared for treatment, assembled for further management or stored.


Storage area: storage area shall be understood to be that part of a waste management installation where waste materials, treatment chemicals or residual material are stored for a limited period.


Entrance area: an entrance area shall be understood to be an area within a waste management installation at which waste is delivered, sorted by weight or volume and identified.


Working areas: working areas shall be understood as areas within the operating site of the waste management installations in which waste materials are handled. The working areas may be located at the entrance, in storage areas or in the treatment area of a waste management installation.
