Rather, the determining factor is whether a large combustion plant incinerates or co-incinerates any "waste", meaning any solid or liquid waste as defined in Article 1(a) of Directive 75/442/EEC (the so-called Waste Framework Directive).

[92] Council directive 94/67/EC of 16 December 1994 on the incineration of hazardous waste (OJ L 365, 31.12.1994, p.34), Council directive 89/369/EEC of 8 June 1989 on the prevention of air pollution from new municipal waste incineration plants (OJ L 163, 14.6.1989; p. 32) and Council directive 89/429/EEC of 21 June 1989 on the reduction of air pollution from existing municipal waste incineration plants (OJ L 203, 15.7.1989, p. 50)

(6) "fuel" means any solid, liquid or gaseous combustible material used to fire the combustion plant with the exception of waste covered by Council Directive 89/369/EEC of 8 June 1989 on the prevention of air pollution from new municipal waste incineration plants(9), Council Directive 89/429/EEC of 21 June 1989 on the reduction of air pollution from existing municipal waste incineration plants(10), and Council Directive 94/67/EC of 16 December 1994 concerning the incineration of hazardous waste(11) or any subsequent Community act repealing and replacing one or more of these D ...[+++]irectives.

This Directive not only applies to solid or liquid waste incineration plants, but also to co-incineration plants.

Furthermore, prior to accepting hazardous waste at the incineration plant or co-incineration plant, the operator of the plant must have at their disposal the administrative information on the generating process, the physical and chemical composition of the waste, as well as on the hazardous characteristics of the waste.

Experimental plants which aim to improve the incineration process and which treat less than 50 tonnes of waste are excluded from the scope of the Directive, as are plants which only treat:
