Sludge co-processing progress and prospects
China has significant potential for the development of cement kiln co-processing technologies of municipal sludge and other solid wastes. In this article, a dry sludge disposal project at a cement plant in Guangdong, China, provides an example of the impact of kiln co-processing on plant operations and air emissions, and puts forward the development direction of this technology in the country....
Buckets of flexibility
In the cement industry high-capacity bucket elevators are used to lift a wide range of bulk materials, including raw mix, limestone, coal, raw meal, clinker and cement. Gambarotta Gschwendt recently received an order...
Beyond primary measures
Under tightening emission legislation, it may be time to consider new technologies and products to remain in compliance. Denmark-based Umicore offers a variety of catalysts for the removal of NO x , NH 3 , dioxins, C...
Graphene’s future potential
Reducing carbon emissions in the cement industry is a top priority, but how to achieve that is the subject of considerable research and development. For First Graphene Ltd and Fosroc International, graphene shows gre...
LC3 in codes and standards
Reducing the carbon footprint of the concrete industry is a priority in the face of global warming. Limestone calcined clay cements (LC 3 ) provide one of the best options to reduce CO 2 emissions. For optimal imple...
Ensuring the quality of calcined clay cement
While calcined clays are fast becoming a sustainable alternative to reduce carbon emissions, ensuring the quality of calcined clay cement is key to gaining widespread market acceptance. By Prof Fernando Martirena-Her...
Asia Cement’s SWAP
