No reduction of odour annoyance in comparison to control area
measures taken are not working sufficiently

Conclusions
Conclusions
Implement a proper complaint management and PR-strategy in time!
In most cases combined environmental stressors are in action! In such a case only comprehensive mitigation measures will bring a sufficient improvement in environmental quality.
Take in mind the diverse perceptions and expectations of technicians and residents!
Technical project management as well as annoyance reduction turned out to be a long term task!
Sometimes competing methods for mitigation are available. Apropriate testing including psychological approaches will facilitate technical expert’s decisions!
