Bottom Ash Utilization


The government encourages the company to implement a 3R (Reduce, Reuse and Recycle) program on hazardous waste independently, because it provides more value to the company itself. In 2016-2017 the ratio of FABA (Fly Ash and Bottom Ash) utilization by PT Semen Indonesia was 51.78%. Due to low ratio utilization of FABA, it is necessary to make additional eforts to increase the ratio. With the increasing utilization ratio of FABA, it is expected that it will extend the life of landfills (stage II). In addition, the efort of utilizing hazardous waste internally has also become a standard for ‘’beyond compliance’’ assessment to obtain Green PROPER rating.

In 2018, Paiton Energy utilized FABA for brick and paving with an investment value of Rp. 1,700,000,000 for procurement of paving machines, construction of workshops, and production capital. This program was expected to reduce FABA by 10%.
