  • Disposal of waste-based fuels and raw materials in cement

    2020-1-1 · 1. Introduction. The use of wastes in cement manufacturing, either as a supplementary fuel or substitute for other raw materials, provides an option for simultaneously eliminating waste and recovering energy and materials [1,2].This concept has been developed and used for co-processing problematic waste such as municipal solid waste (MSW), sewage sludge, Waste materials co-processing in cement industry,2013-3-1 · Waste materials used for co-processing are referred to as alternative fuels and raw materials (AFR) . Before this waste is put into clinker (the main raw material for cement) furnaces, there are pre-treatments to ensure that waste characteristics remain constant and it will not cause adverse effects to the cement produced or to the environment.

  • Innovative reuse of concrete slurry waste from ready

    Concrete slurry waste (CSW) is generated from ready-mixed concrete plants during concrete production and is classified as a corrosive hazardous material. If it is disposed of at landfills, it would cause detrimental effects for our surrounding environment and ecosystems due to its high pH value as well as heavy metal contamination and accumulation.(PDF) Alternative Fuels from Waste Products in Cement ,The main alternative fuels used in cement industry are. residue oil and solvents, contaminated wood and process waste from wood, used. tires and rubber waste, plastic waste, thermal fraction of
