Abstract

Background Between 2005 and 2006, the IZT carried out a research project funded by the BMU. The background was, on the one hand, the adaptation of the subsidy to current market developments and the review of technical requirements and environmental standards required by the market incentive programme, and, on the other hand, conformity with European environmental subsidy law, which only allows environmental subsidies if the existing technical standards are exceeded. A particular focus of the project was to determine the extent to which the environmental impacts of selective coating can be used to develop environmental standards. Approach The entire project was divided into five work packages: 1.) Market analysis, 2.) Analysis of the environmental impacts, 3.) Life cycle assessment of the coating processes including an individual life cycle assessment of the emissions of hexavalent chromium (Cr 6+) in the upstream chains, 4.) Durability test according to Task 10 of the IEA including a life cycle assessment and 5.) Derivation of environmental standards. Intermediate and final results of the project were discussed in the context of a scientific and an industry workshop and adapted accordingly on the basis of the resulting new findings.
