PT Semen Indonesia (SIG) has signed a memorandum of understanding with Masyarakat Energi Biomassa Indonesia to strengthen cooperation on biomass and waste-derived fuels for cement production.
The agreement, signed on 4 November, provides a framework for cooperation as SIG seeks to increase the substitution of conventional fuels across its operations.
SIG reported alternative-fuel consumption of 501,264t in the first nine months of 2026, with its thermal substitution rate rising from 9.58 to 10.35 per cent. The rate measures the proportion of thermal energy supplied by alternative fuels.
The company announced the agreement on 10 November but disclosed no contracted supply volumes or investment commitments.
