The Official Journal of the European Union published the Best Available Techniques (BAT) conclusions for Common Waste Water and Waste Gas Treatment/Management Systems in the Chemical Sector. These BAT conclusions address a number of issues relevant for all chemical installations covered by the Industrial Emissions Directive: environmental management systems; waste water management, collection, and treatment; waste gas management and collection; diffuse emissions of volatile organic compounds to air; odour emissions; and noise emissions. BAT conclusions are the technical basis for national authorities in EU countries to set permit conditions for producers in the relevant field and aim at achieving a high level of protection of the environment under economically and technically viable conditions.
