European Union Directive on integrated approach to pollution prevention and control (IPPC Directive Integrated Pollution Prevention and Control) aims to reduce and permanently monitor the pollution derived from industrial and agricultural activities by preventing or reducing pollution emissions into the environment, including measures concerning waste, in order to achieve a high level of environmental protection as a whole. With accepting IPPC Directive in the European legislation the term BAT (Best Available Technique engl.) was introduced. This directive defines the term with a number of characteristics, one of which is the requirement to have a viable technology in the economic and technical sense, as well as 12 conditions that must be taken into account when determining BAT. BAT are listed in the document BREF (BAT Reference Document) prepared by the Commission. As regards the processing of waste, the directive provides a list of industrial activities which it embraces. Integrated approach (prevention and control of pollution) implies a change of licensing for the company. The basic principle of the Directive is that he who shall issue regulations and supervise their implementation, as well as those who carried them, they must examine each industry as a whole, and its overall (air, water, soil) impact on the environment, before taking any technological measures that are necessary to achieve the required level of environmental protection. The aim of these licenses is to avoid moving the pollution from one medium to another and to promote preventive measures to prevent formation of waste at source, primarily measures of cleaner production and application of best available technology (BAT). Spirit of the Directive encourages the waste whose formation could not be avoided, to be recycled or processed by some of the BAT technology and disposed in an environmentally sound manner. Directive and the proposed BAT technology also contribute to the rational use of energy and resources saving, reduce the risk of accidents and allows the site after the industry ceases to operate, to be brought in the original condition (repair).
