Capturing World's Attention, SIG’s Green Energy Initiative at Semen Tonasa Awarded in the Energy Management Leadership 2023 Event

Successfully reducing consumption and achieving energy cost efficiency based on ISO 50001 since 2019, PT Semen Tonasa, a subsidiary of PT Semen Indonesia (Persero) Tbk (SIG), is named one of only two companies in the world to win the Award of Excellence in Energy Management from the Clean Energy Ministerial (CEM) at the 2023 CEM's Energy Management Leadership Awards. The award was presented by the Minister of Energy & Mineral Resources, Arifin Tasrif, to the President Director of PT Semen Tonasa, Asruddin accompanied by SIG’s Director of Operations, Reni Wulandari in Goa, India, on Friday (July 21^st , 2023).  

 PT Semen Tonasa has been consistently implementing energy management system based on ISO 50001, which aligned with SIG sustainable roadmap that covers the Company’s measures to ensure sustainable operations by considering issues on environmental, social and GCG (ESG).   

Over the course of four years since the ISO 50001 implementation in 2019, PT Semen Tonasa achieved $16.1 million of the total energy savings, or equivalent to 4.3 million Gigajoule (GJ) of energy savings with a total CO₂ emission reduction of 436 thousand metric tons.  

In terms of energy management, PT Semen Tonasa utilized in total 157 thousand tons of biomass from agricultural waste as alternative fuel that contributes to significant increase of Thermal Substitution Rate (TSR) from 1,17% to 8,13% between 2019 and 2022. While securing alternative fuel, the Company made sure the biomass utilization undergone adjustments in raw mix design and critical operating parameters to maintain product quality.  

CEM is a renowned global forum facilitating the largest and leading nations in the world, international organizations and companies, to promote policies and programs on clean energy technology advancement, to share lessons learned and best practices, as well as to encourage the transition to a global clean energy economy through ISO 50001 implementation. This year, two organizations/companies worldwide are awarded Excellence in Energy Management and fifteen organizations/companies are awarded on Energy Management Insight, for energy management systems implementation and increasing the global awareness of economic benefits and sustainability.  

President Director of SIG, Donny Arsal stated that, this award is an appreciation and well-recognition for SIG’s sustainability commitment on the Environment Conservation pillar that cascaded down to five priority subjects namely Energy & Climate Risks Management, Circular Economy Management, Air Emission Management and Biodiversity Management.   

“SIG is beyond proud of PT Semen Tonasa’s achievement in winning the Award of Excellence in Energy Management at the 2023 CEM's Energy Management Leadership Awards. This motivates us even more to improve the implementation of sustainability principles in all operational activities. Sustainability is the key to securing the future for all as well as the Company's resilience in years to come”, said Donny Arsal.  

Furthermore, Donny Arsal added that SIG's Sustainability Road Map encompasses various strategic initiatives for energy conservation and efficiency in company operations. These initiatives include reducing clinker factors, utilizing alternative fuels from industrial waste, biomass, and municipal solid waste converted to refuse-derived fuel (RDF), hydrogen injection and thermal energy efficiency (STEC). SIG also supports the development of renewable energy using solar panels to substitute electricity in its operational units and optimization of waste heat from cement production processes (Waste Heat Recovery Power Generation).   

“Through these strategic initiatives, SIG succeeded in reducing energy consumption from 108.5 GJ in 2021 to 94.2 GJ in 2022. Emission intensity was also successfully reduced to 590 kg CO2/ton cement equivalent in 2022, it is a 16,67% decrease from the 2010 baseline of 708 kgCO2/ton cement equivalent”, said Donny Arsal.
