The production of hydrated lime, a key ingredient in the CFBFA composite gravels, remains the most energy-consuming step in the entire process. Despite this, the overall energy demand for CFBFA composite gravels is much lower than traditional materials, largely due to the reduction in energy required for other stages of production.
