Brazil: Cimento Apodi said that it has recorded a 20% thermal substitution rate (TSR), avoided 1500t/yr of CO₂ emissions and invested more than US$4.7m in a new 5MW solar park. The producer has targeted a 25% TSR by the end of 2025.
It says it will increase renewable energy use through its solar park and a waste heat recovery system. Together these will supply 25% of its electricity demand by the end of 2025. The implementation of the cement mill optimiser (CMO), an artificial intelligence-based system developed with the Federal University of Ceará and the Titan Group, has increased mill productivity by up to 13% and installed capacity by 10%. The company is also developing gasifiers that can reduce emissions by up to 10% per tonne of cement.
The integrated Quixeré cement plant coprocesses byproducts such as tyres, cashew nut shells, açaí seeds, carnauba stalks and industrial waste from other sectors. All materials undergo sorting and characterisation to meet the parameters of particle size, moisture and calorific value.
