JAKARTA - Successfully reducing consumption and achieving energy cost efficiency with the implementation of ISO 50001 implemented since 2019, PT Semen Tonasa, which is a subsidiary of PT Semen Indonesia (Persero) Tbk (SIG), was selected as one of two companies in the world that won the Award of Excellence in Energy Management from Clean Energy Ministerial (CEM) at the 2023 CEM's Energy Management Management Awards.

The award was handed over by the Minister of Energy & Mineral Resources, Arifin Tasrif, to the President Director of PT Semen Tonasa, Asruddin who was accompanied by the Director of Operations for SIG, Reni Wulandari in Goa, India, on Friday, July 21, 2023.

PT Semen Tonasa consistently implements an ISO 50001-based energy management system that is in line with the SIG sustainability road map to ensure sustainable company operations and consider Environmental, Social and Governance (ESG) issues.

Within four years of implementing the ISO 50001-based energy management system in 2019, PT Semen Tonasa has proven successful in recording energy cost savings with a total of 16.1 million US dollars or equivalents with energy savings of 4.3 million Gigajoule (GJ), as well as reducing CO2 emissions by 436 thousand metric tons.

One of the initiatives carried out by PT Semen Tonasa in energy management is by utilizing biomass sourced from agricultural waste as alternative fuel. The level of biomass thermal substitution (TSR) in PT Semen Tonasa's production activities was recorded to have increased significantly from 1.17 percent to 8.13 percent in the period between 2019 and 2022 with a total amount of agricultural waste utilized by 157 thousand tons.

The increase in the use of biomass has gone through an adjustment process on the raw mix design and critical operating parameters (COP) to maintain product quality.

CEM is a high-level international forum that unites the world's largest and leading countries, international organizations, and companies, to achieve missions to accelerate the clean energy transition through the implementation of ISO 50001.

In 2023, the CEM's Energy Management Leadership Awards award the Award of Excellence in Energy Management to two companies and the Energy Management Insight Awards to fifteen other organizations, which are considered to have implemented an energy management system and raised global awareness of economic and sustainability benefits.

GIS President Director, Donny Arsal said, this award is an appreciation as well as an acknowledgment of SIG's sustainability commitment, especially in the pillars of Environmental Protection which is manifested through five priority topics, namely Climate and Energy Risk Management, Circuit Economic Management, Air Emission Management, Water Management and Biodiversity Management.

"SIG is proud of the achievement of PT Semen Tonasa which won the highest award for the Award of Excellence in Energy Management at the 2023 CEM's Energy Management Awards. This achievement further motivates us at the GIS Group to increase the application of sustainability principles in all operational activities. Because sustainability is the key to creating a good life for all living things on earth and maintaining the resilience of the Company in the future," said Donny Arsal.

Furthermore, Donny Arsal said, the Sustainability Road Map GIS includes various strategic initiatives that contribute to decarbonization through a decrease in the peak factors, the use of alternative fuel for urban waste managed to refuse-derived fuel (RDF), hydrogen injection and thermal energy efficiency (STEC).

In addition, SIG supports the development of renewable energy through the use of solar panels for electricity substitution in its operational units, as well as optimization of hot gas exhaust from the cement production process (Waste Heat Recovery Power Generation).

"Through this strategic initiative, GIS succeeded in reducing energy usage from 108.5 million GJ in 2021 to 94.2 million GJ in 2022. Emission intensity was also successfully reduced to 590 kg of CO2/ton cement equivalent in 2022, or decreased 16.67 percent from the 2010 baseline of 708 kgCO2/ton cement equivalent," said Donny Arsal.
