Cement kiln co-processing refers to the use of waste materials (such as industrial waste, municipal solid waste, waste plastics, waste oils, etc.) as alternative fuels, which are fed into the cement kiln for incineration alongside traditional fuels like coal.
Solutions
Shreedding-Mixing-Pumping
Closed shredding system
Sludge
Alternative fuel-example 1
Alternative fuel-example 2
Advantages of SID solution
- Improved combustion and thermal efficiency.
- Reduced chlorine and sulfur-containing substances, extending kiln life.
- Optimized alternative fuel composition, reducing temperature fluctuations, and suppressing the generation of most harmful by-products.
- Materials such as slag and sludge, after treatment, can be used as cement raw materials, improving resource utilization and reducing dependence on natural resources.
Processed materials
Industrial solid waste, municipal solid waste, biomass, textiles, rubber and plastics, etc.

Municipal solid waste, alternative fuel disposal system
Through multiple processes including shredding and screening, waste is treated to achieve both resource recovery, and energy production. This not only efficiently handles waste but also enhances energy efficiency in cement production and reduces environmental pollution.
