Directions for drying RDFs - interview with Yves Marc Schade, stela Laxhuber

Yves Marc Schade, Stela Laxhuber, discusses at World Cement Magazine the potential for operators to reduce their emissions using refuse-derived fuels and offers advice on the best techniques and machinery available to prepare these materials for efficient, sustainable combustion.

Refuse-derived fuel (RDF) is produced with municipal solid waste that has been processed to remove non-combustible materials. Belt dryers are commonly used in the RDF production process to dry the waste material before it is converted into fuel. Some of the advantages of low-temperature belt dryers for drying RDF are:

Belt dryer advantages

Overall, low-temperature belt dryers offer several advantages over high-temperature dryers for drying RDF, including energy efficiency, reduced emissions, high-quality product, improved safety, and versatility.
RDF can be used in a carbon neutral cement production process by replacing fossil fuels, such as coal and natural gas, which are traditionally used as the primary energy source in cement manufacturing. Here are some ways RDF can be utilised to achieve CO2 neutrality in cement production:

Working with RDF

The use of RDF in cement production can reduce the carbon footprint of the cement manufacturing process and help achieve CO2 neutrality. By utilising RDF as an alternative fuel and recovering its energy content, the need for fossil fuels can be reduced, resulting in lower emissions. Additionally, by capturing and storing CO2 emissions, the cement production process can become carbon neutral or even carbon negative. The use of RDF is likely to have a significant impact on cement production in the future. As the world seeks to transition to more sustainable and low-carbon energy sources, RDF has emerged as a viable alternative fuel source for cement production. Here are some ways in which the usage of RDF is likely to impact cement production in the future:


Overall, the use of RDF is likely to have a significant impact on cement production in the future, helping to improve the sustainability and efficiency of the cement manufacturing process while reducing the industry’s impact on the environment.
