Research cooperation for the utilization of Fly Ash Dan Bottom Ash at UPTE, PT. Bukit Asam

Year of research: 2019-2021

Source of funds: PT Bukit Asam, TBK.

Research on "Utilization of Fly Ash and Bottom Ash at UPTE, PT. Bukit Asam "includes the mapping and characterization of coal in the PTBA working area, characterization of existing fly ash and bottom ash (FABA) from PLTU PTBA as raw material of cenosphere and Rare Earth Element (REE) as well as the manufacture of geopolymer concrete. In addition, there is also a study of ashing against coal that has the potential to contain high REE and characterization and its REE.
