Semen Indonesia Transitions from Diesel to CNG to Reduce Carbon Emissions

PT Semen Indonesia (Persero) Tbk (SIG) has taken a concrete step towards reducing carbon emissions by adopting Compressed Natural Gas (CNG) as the primary fuel for its cement milling machines at PT Semen Gresik Pabrik Rembang, one of its subsidiaries.

This transition is part of the company's efforts to contribute to lowering carbon emissions and promoting environmental sustainability. According to Corporate Secretary SIG Vita Mahreyni, the use of CNG is not only more environmentally friendly but also improves gas combustion efficiency, thus helping to reduce fuel consumption and CO2 emissions. The shift from diesel to CNG in all cement milling machines at PT Semen Gresik Pabrik Rembang is expected to decrease the carbon emissions from the combustion process from 74.1 kg CO2 per GJ to 56.1 kg CO2 per GJ.

In addition to the transition to CNG, the company has also increased the use of solar panels and biomass at PT Semen Gresik Pabrik Rembang to further reduce emissions. Currently, the subsidiary has 30 solar panels with a capacity of 14.55 kWp installed, and the use of biomass from rice husks, corn cobs, plastic packaging, and leather waste for heat energy substitution has reached 1.5% in 20231.Vita highlighted that these environmentally friendly innovations have helped PT Semen Gresik Pabrik Rembang achieve the Good Mining Practice and Tamasya (Mining that Benefits the Community) Award from the Ministry of Energy and Mineral Resources, as well as the Green PROPER (Program for Environmental Performance Rating) award.
