Techno-economic analysis shows that the process is energy-efficient with the cost of ~$21 ton−1 in electrical energy.Coal fly ash (CFA) is an attractive diluent additive in cement due to its widespread availability and ultralow cost.

The process also lets heavy metals that have evaporated be put in a vacuum chamber to keep them from entering the environment.
