Based on the Industrial Emissions Directive (2010/75/EU), the European Commission started 2014 an information exchange on best available techniques (BAT), aiming at the revision of the BAT Reference Document for Surface Treatment Using Organic Solvents” (STS BREF 2007). Germany participates actively in the information exchange to promote an ambitious level of environmental regulation in Europe. The research project evaluated and documented best available techniques in plants in Germany. Technical information and emission data were documented and assessed for these plants, either applying process-integrated measures or end-of-pipe techniques for emission reduction.
