Rotary kilns have been in use for many decades and are proven technology. They are often used behind closed doors for the production of basic materials (e.g. pigments, foodstuffs). In the energy or waste sector, there were also plants in Germany that were in operation for more than 30 years, but were also shut down for reasons of age.
Due to the new requirement "CircularEconomy" or quite currently "Substitution of fossil energy sources", this proven technology suddenly gets completely new opportunities, which will be presented in the lecture. The participants can expect a delimitation of the possible processes, as well as opportunities and risks up to the use in Waste2Hydrogen.
