Half-timbered, cement works and RDF

We invited to the 11th SEC technology tour from 12-13 Sep 2021 in Eichsfeld. The program included a guided tour of the romantic half-timbered town of Duderstadt, a joint dinner followed by an overnight stay in the Duderstadt area. The next day, the focus was on the "technology" part: in the morning we had the opportunity to get to know the processing of plastic waste, which is used as fuel in the neighboring cement works. To top it all off, we visited the cement works in Deuna in the afternoon.

Duderstadt

Duderstadt is one of the most beautiful half-timbered towns in Germany, which we visited on the afternoon of our arrival day, a Sunday. We then drove to Fuhrbach, where we had dinner and stayed the night together.

plastic processing

The next morning we had an appointment with the company B+T Group in Deuna. The B+T Group (based in Alsfeld) is a supra-regional association of individual companies from the waste disposal sector. It takes on tasks in northern Hesse, Lower Saxony and Thuringia. Your strength is logistics! On the premises of Deuna Cement GmbH, secondary fuel is produced from pre-sorted commercial waste according to the requirements of the cement works and used there directly as fuel.

Cement plant Deuna

The Deuna cement plant of Dykerhoff GmbH was founded in 1975 and today produces approx. 2 million tons of cement per year, especially cement for precast concrete parts. The secondary fuel from B+T is burned there in two huge rotary kilns. In the Deuna cement works, it has a fuel share of approx. 80%. The visit also included a bus ride to the open pit limestone mine northwest of the cement plant.

A report on the excursion appeared in the Nachrichten aus der Chemie: Nachr. Chem. 2021, 69 (12), 91.
