We hereby invite you to the 11th SEC technology tour from 12-13 Sep 2021 in the area around Eichsfeld. The program includes a guided tour of the romantic half-timbered town of Duderstadt, a joint dinner followed by an overnight stay in the vicinity of Duderstadt. The next day, the focus is on the "Technology" part: In the morning we have the unique opportunity to get to know the processing of plastic waste that is used as fuel in the neighboring cement works. To top it off, we are allowed to visit the Deuna cement works in the afternoon. As in 2019, this trip is also associated with at least one overnight stay in a hotel. The 12 Sep 21 is a Sunday. So a long weekend would be a good idea. There are enough destinations in the area, for example Harz, Erfurt or Göttingen.
Duderstadt is one of the most beautiful half-timbered towns in Germany. The old town fortifications with the Westerturm ensemble, imposing churches, the old town hall from the 14th century and 600 colorful half-timbered houses from different eras adorn the picturesque old town.
We have reserved a one and a half hour city tour for us on the afternoon of the day of arrival, a Sunday. Afterwards we drive a little in the country (7 km to Fuhrbach), where we have dinner and spend the night together.
The next morning we have an appointment with the B + T Group in Deuna (approx. 40 minutes drive from Fuhrbach). The B + T Group (based in Alsfeld) is a supra-regional association of individual companies from the waste disposal sector under one roof. It takes on disposal, processing or supply tasks in North Hesse, Lower Saxony and Thuringia. Your strength is the associated logistics! On the premises of Deuna Zement GmbH, secondary fuel is produced from pre-sorted commercial waste in accordance with the requirements of the cement works and used there directly as fuel.
Dykerhoff GmbH's Deuna cement plant was founded in 1975 and today produces around 2 million tonnes of cement per year, especially cement for precast concrete parts. The cement works is dominated by two huge rotary kilns, in which the secondary fuel from B + T that we got to know in the morning is also burned. In the Deuna cement plant, the proportion of secondary fuels used in burning cement clinker is approx. 80%. The tour also included a bus ride to the limestone open-cast mine northwest of the cement works.
A report on the excursion appeared in the Nachrichten aus der Chemie: Nachr. Chem. 2021, 69 (12), 91.
