On Indonesia's Sulawesi Island, young engineers from PT DSSP Power Kendari have collaborated with local universities to develop fly ash from the power plant into a new material—fly ash geopolymer artificial reefs—while simultaneously carrying out coral transplantation. This innovative practice has successfully converted thermal power solid waste into marine ecological substrates, boosting the survival rate of transplanted corals to 89% and effectively improving the ecological environment of the local waters. It truly achieves the transformation of "turning industrial waste into an underwater oasis."
