Definition of ‘hazardous waste’Waste containing any of the hazardous constituents listed in Annex 2 (51 constituents)Waste showing any of hazardous properties listed inAnnex 3 (14 properties), orWaste containing substances classified as hazardous and in total exceeding a threshold level
What are What are ‚‚hazardous hazardous constituentsconstituents’’??
Main hazardous constituents of Waste Wood areC 3 hexavalent chromium compoundsC 6 copper compounds C 8 arsenic compounds C 20 inorganic fluorine compounds C 34 biocides C 42 organochlorinated compounds C 43 aromatic, polycyclic and heterocyclic compounds
What are What are ‚‚hazardous propertieshazardous properties ’’??
Main hazardous properties of Waste Wood areH 5: harmful, or containing one or more substances
classified as harmful at a total concentration ≥ 25%E.g. Copper
H 6:very toxic, or containing one or more substances classified as very toxic at a total concentration ≥ 0,1%E.g. Arsenic, Chromium (VI)toxic, or containing one or more substances classified as toxic at a total concentration ≥ 3%
H 14: ecotoxic (regulation not specified)

The general principles are
To AVOIDTo REDUCE To REUSE or to RECYCLETo ELIMINATE
What is What is ‚‚WasteWaste‘‘??
For the purposes of the Closed Substance Cycle and Waste Management Act
"Waste" shall mean all movable property … which the holder discards, or intends or is required to discard"Waste for recovery" is waste that is recoveredWaste that is not recovered is "waste for disposal"
Ordinance on the Management Ordinance on the Management of Waste Woodof Waste Wood
The Ordinanceentered into force 1 March 2003shall guarantee a nationwide standard for waste wood managementshall lead to greater equality of competition for the small to medium waste management companiesensures that pollutants are eliminated from the economic cycle
Ordinance on the Management Ordinance on the Management of Waste Woodof Waste Wood
The Ordinanceis considered a pilot project for material-specific ordinances
It is a significant volume flow for waste recovery,It is suitable for both substance recycling and energy recovery,The environmental compatibility of some of the recovery paths for waste wood currently in practice is questionable, andThere is an urgent need for standard nationwide regulation in view of the different regulations of the German Länder
Ordinance on the Management Ordinance on the Management of Waste Woodof Waste Wood
The Ordinanceapplies to both residual wood from industry and wood products that have become wastewaste wood
includes residues from the working and machining of wood and derived timber products (> 50% by mass)wood packaging, palettes, furniture and waste wood from demolitiondoes not include wood chips from saw mills or forest thinning
Ordinance on the Management Ordinance on the Management of Waste Woodof Waste Wood
The Ordinanceidentifies and covers all the common methods of waste wood management
such as preparing waste wood for the production of derived timber productsthe production of active carbon or industrial charcoal and synthesis gasthe energy recovery of waste wood as a substitute fuel
If waste wood cannot be recoveredit must be disposed of using thermal processesland filling is not permitted since 2003

Waster Timber CategoriesWaster Timber Categories (I)(I)
A I:Waste timber in its natural state or only mechanically worked which, during use, was at most insignificantly contaminated with substances harmful to woodA II:Waste timber which has been bonded, coated, painted, lacquered or treated otherwise without halogenorganiccompounds in the coating and without wood preservatives
Waster Timber CategoriesWaster Timber Categories (II)(II)
A III:Waste timber with halogenated organic compounds in the coating, without wood preservativesA IV:Waste timber treated with wood preservatives, s.a. sleepers, poles, hop-poles, vineyard-poles and other waste timber which cannot be classified in one of the classes A I – A IIIIrrespective of the kind of wood preservative and retention !Including antibluestain chemicals and fire retardants !
What areWhat are ‚‚Wood Wood PreservativesPreservatives‘‘??
For the purposes of the Ordinance on the Management of Waste WoodW/P are substances used in woodworking and machining having a biocidal effect against hylophagous insects and fungi as well as fungi which discolour the wood, as well as substances for reducing the flammability of wood
