SIG Using Renewable Energy to Support Net-zero Carbon Goal

TEMPO.CO, Jakarta - State-run cement corporation PT Semen Indonesia / Semen Indonesia Group (SIG) said it is supporting the government's efforts towards realizing net-zero carbon emissions by 2060 through the use of new and renewable energy (EBT).

"Since 2021, we have carried out several programs as part of SIG Sustainability Initiatives to support the reduction of carbon emissions," SIG corporate secretary Vita Mahreyni said in a statement released here on Saturday.

The initiatives have included reducing the clinker factor, increasing the use of alternative fuels, as well as improving electricity and thermal energy efficiency, she informed.

In addition, the company has intensified the utilization of renewable energy by installing solar panels, she said.

SIG's commitment to realizing the 2060 Carbon Neutral Program has been underlined by the inking of a cooperation MoU with state-owned classification bureau of Indonesian-flagged vessel PT Biro Klasifikasi Indonesia on February 2, 2022, she added.

The MoU was signed by SIG president director Donny Arsal and BKI president director Rudiyanto, and was witnessed by First Deputy Minister of State-owned Enterprises, Pahala Nugraha Mansury, Mahreyni said.

"We have completed a pilot project for the installment of 10-kilowatt (kW) solar panels in a number of plants, such as at Group Head of Plant Operation (GHoPO) at the Tuban factory complex, Semen Padang production site, and Semen Tonasa manufacturing site,” SIG's corporate secretary informed.

The solar panels have been operating well and producing electrical energy for running factory equipment at each site, she noted.

Furthermore, the company is also controlling emissions generated during the production process through the use of electrostatic precipitator system technology, conditioning towers, and bag filters at the factory sites to manage dust emissions, she informed.

SIG is also utilizing waste heat recovery power generation (WHRPG) technology, which turns the exhaust heat from the combustion process into renewable energy at the Tuban and Indarung factory sites, she said.

"In addition, we are processing the waste collected from nearby cities into refused derived fuel (RDF) as a substitute for coal at the Narogong and Cilacap factory sites as a solution for better community environmental management," Mahreyni added.
