16th Joint DDBST User and UNIFAC Consortium Member Meeting Closed

The 16th joint DDB user and UNIFAC consortium member meeting took place on Tuesday, September 18th

We were very happy that we could welcome participants from a wide variety of companies and countries. We had several customer lectures together with several talks of our own people.

We would like to thank all participants for their contributions and hope we will keep in touch and see most of this year's participants also in the next year.
