Management Approach

Energy Efficiency Management

GGC has implemented and achieved certification for the energy management system in accordance with ISO 50001:2018. GGC has carried out the Efficiency-Driven Roadmap across all production processes, demonstrating efficient energy utilization, continuous improvement, and strict compliance with applicable laws and regulations.

Efficiency-Driven Road Map

Efficiency-Driven 2023 2024 - 2025 2026 - 2030
Enhancing operational efficiency and reducing waste generation

1. Utilize low-carbon energy or renewable energy sources

  • Low-carbon energy such as natural gas
  • Renewable energy sources such as solar power, biomass, and biogas

2. Implement operational efficiency measures

  • Efficiency-enhancing investments
  • Real-Time Monitoring and Data-Driven Operational Optimization
  • Proactive Maintenance

Energy Action Plan

GGC has developed an energy action plan to enhance operational efficiency, reduce energy consumption, and minimize greenhouse gas emissions at each production facility in alignment with its strategy and the Efficiency-Driven Plan. The action plan consists of the following:

  1. Explore additional renewable energy sources such as solar power, biomass, and future bioenergy to support the achievement of Net Zero by 2050.
  2. Enhance production processes, including efficiency-enhancing investments, real-time monitoring and data-driven operational optimization, and proactive maintenance.
  3. Conduct research and development to reduce non-renewable energy consumption through production process efficiency projects, including reducing electricity and fuel consumption, minimizing resource losses, and reducing greenhouse gas emissions by deploying high-efficiency technologies. These measures not only reduce costs for GGC but also align with sustainable development practices.
  4. Evaluate and monitor the progress of each project regularly by comparing energy reduction performance before and after implementing efficiency initiatives to identify issues and undertake corrective actions, ultimately improving GGC’s energy performance.
  5. Provide training on energy- and environment-related topics to all employees across departments to enhance their knowledge of efficient energy use in operations and workplaces, as well as to encourage new ideas for energy-saving initiatives through training programs.

Energy Efficiency Training

GGC places strong emphasis on enhancing employees’ knowledge of energy management, with energy efficiency included as one of the training topics. In 2025, GGC will implement the following employee training programs:

Insight ISO 50001:2018 Training

GGC organized training on the energy management system in accordance with ISO 50001:2018, a standard for systematic energy management that can be integrated with other ISO systems. The training program was designed by ConicleX and delivered by experienced instructors, enabling employees to understand the content easily with minimal learning time. The program covered the following topics:

  1. Energy management planning and implementation
  2. Emerging trends in energy management
  3. Relevant regulatory requirements
  4. Integration with other legal requirements

Outcomes and Benefits

  • All employees of the company participated in the training.
  • Employees gained an improved understanding of energy management systems, industry trends, and energy-related regulations.

Energy Efficiency Project

To achieve the goals of reducing energy consumption and reaching Net Zero greenhouse gas emissions, GGC has implemented several projects to improve energy efficiency and increase the use of renewable energy. In 2025, the following energy efficiency projects were initiated:

1. Renewable Energy from Biogas

GGC increased the proportion of renewable energy by utilizing biogas to reduce fuel consumption in steam and heat generation processes. Biogas is produced from by-products generated during Glycerin production and reused as an energy source. This project can reduce energy consumption by more than 23,677 tons of CO₂ equivalent, and reduce fuel costs for steam and heat production by 10,788,181.16 baht

2. Replacement new type of steam traps for reduce steam loss

GGC implemented a project to reduce steam loss caused by damaged or leaking steam traps while extending equipment lifespan. Steam traps were replaced with types more suitable for operational conditions. The project resulted in an energy reduction of 164.43 megawatt-hours, equivalent to 24 tons of CO2e.

3. Optimize Air Blower of Wastewater Treatment System

GGC carried out a project to optimize the control of dissolved oxygen (DO) levels in the wastewater treatment system with the objective of reducing energy consumption from air blowers. The DO Control Range was adjusted for greater operational efficiency while maintaining aeration effectiveness and wastewater treatment stability in accordance with required standards. The project achieved an energy reduction of 220.85 megawatt-hours, equivalent to 74 tons of CO2e.
