The aim pursued by this Directive is the approximation of the laws of Member States on the controlled management of hazardous waste. Domestic waste shall not fall within the scope of the Directive. Member States shall take all necessary measures to require that on every site where discharge of hazardous waste takes place the waste is recorded and identified. Moreover, Member States shall ensure that establishments and undertakings which dispose of, recover, collect or transport hazardous waste are required not to mix different categories of hazardous waste nor mix hazardous waste with non hazardous waste. Where waste has already been mixed, separation must be effected. Article 5 concerns packaging and labelling of waste and regulates related inspective activities. In accordance with article 6, the competent authorities of each Member State shall draw up plans for the management of hazardous waste and shall make these plans public. Annex I lists out the categories or generic types of hazardous waste according to their nature or the activity which generated them. Waste may be liquid, sludge or solid in form. Annex II indicates the constituents of the wastes in Annex I B which render them hazardous when they have the properties described in Annex III.
