Energy
Energy Consumption
1. Utilizing energy-efficient devices (lighting, air conditioning)
  • In 2024, WIKA Beton achieved 75% LED lighting usage in factory offices and 100% usage across all Concrete Product Plant work units.
  • Additionally, the Company utilizes B35 biodiesel for its operational vehicles, with selected units already adopting B40 biodiesel.
2. Optimizing the use of digital technology
  • Using monitoring Dashboard for Solar Power Plant (PLTS).
3. Using electric vehicles for operational activities
  • Currently, WIKA Beton operates 22 electric motorcycles for operational activities. The Company has set a target to achieve 100% electric vehicle usage across all factory areas by 2030.
  • WIKA Beton also operates one electric vehicle designated for the President Director. By 2030, the Company targets the entire Board of Directors to use electric vehicles for their operational needs.
4. Increasing the use of new and renewable energy through the installation of solar panels across strategic facilities
  • In 2024, 561 kWp of solar capacity has been installed at PPB Bogor and Majalengka. Expansion efforts are currently underway at PPB Sumut, Lamsel, and Pasuruan, with a planned total capacity of 879.2 kWp. These measures significantly support the Company's energy efficiency targets.
5. Implementing non-steam innovations to accelerate the production process, thereby reducing cycle time
  • Currently, all WIKA Beton plants no longer use boiler machines for the evaporation process. This new method replaces the steam method by using a polycarboxylate mixture to speed up the curing process and significantly reduce the use of electricity and gas.
Energy Consumption Reduction & Efficiency

To reinforce the Company's commitment to responsible energy management and support sustainability compliance, the Company organized a Sharing Session titled Energy Consumption Reduction and Efficiency on Wednesday, November 19, 2025, from 09:00 to 11:00 WIB via Zoom Meeting.

The session featured experienced environmental practitioners who provided a comprehensive overview of global climate risks, the urgency of the energy transition, and corporate strategies for emission reduction through energy efficiency and conservation. The training covered several critical concepts, including:

  • Understanding renewable versus non-renewable energy sources;
  • The background and urgency of energy efficiency, including its correlation with Greenhouse Gas (GHG) emission reduction;
  • Principles of energy management, energy audits, and the implementation of Significant Energy Use (SEU);
  • Practical approaches to enhancing energy performance through energy conservation, energy efficiency, and energy recovery;
  • Energy Consumption Intensity (ECI) as a key indicator of corporate energy performance; and
  • Opportunities for adopting renewable energy to support the decarbonization roadmap.

The training material focused on strategic approaches to reducing Scope 1 and Scope 2 emissions, ranging from production process optimization and energy management to the utilization of electrification technologies, as outlined in the presentation documents (referencing the scope concepts and energy transition roadmap).

This initiative was organized to raise employee awareness regarding the importance of efficient energy management and to drive operational behavioral changes toward energy-saving practices across all work units. Through this program, the Company is committed to strengthening its culture of sustainability, reducing environmental impact, and supporting national and global targets for climate change mitigation.

Water Consumption(m3)
Water Efficiency Management Programs

WIKA Beton implements a comprehensive Water Efficiency Management program to reduce water intensity per unit of product and strengthen responsible water stewardship across its operations. By the end of 2024, the Company achieved a total water consumption reduction of 2.63%, exceeding its 2024 target of 2%, through the integrated implementation of water efficiency and wastewater management initiatives. Going forward, WIKA Beton is committed to continuously improving its water performance by targeting an additional minimum reduction of 0.5% in total water consumption year-on-year compared to the previous year.

Key Programs:

  • Optimizing concrete mix design by adjusting cement composition and admixture usage to reduce the water–cement ratio, thereby improving water efficiency in the production process.
  • Waste water management (effluent) in factories (utilization of recycled water for production needs)
  • Reduction of domestic/RT wastewater, processing in IPAL and sanitation for watering plants and dust on the road
Water Consumption in Water-Stressed Areas
