Environmental Management
Ratch Pathana Group & Affiliates have defined environmental objectives committed to continual develop the environmental management system to ensure the effectiveness and meet the internaltional standard, as well as running business with environmental and social responsibility.
Water Management
Ratch Pathana Group places the importance of the effective water management throughout all production processes, from the source of water for production input until the preservation of the environment after production process. The company therefore strictly adheres to regulations of water management and considers the impacts of water consumption to the nearby communities. On the other hand, Ratch Pathana Group also plans to prevent the risk of water shortage which may interrupt the power plant operations.

Target for Reducing Raw Water use in the Energy Production Process in 2023
Air Emission Management
Strictly implement air pollution management measures as follows:
- The emission monitoring system is installed at the stacks of the power plant for measuring the amount of TSP, SO2 , and NO2 emitted to the atmosphere. The results indicated that the amounts of those pollutants are within the legal limits.
- Installed the emission monitoring system in the communities’ area nearby the power plant, composing environmental monitoring reports in every 6 months for the related sectors and public to ensure that the air qualities are according to the standards and regulations.
- The Electrostatic Precipitators (ESP) with 99.5% of particulate-collecting efficiency was installed at the biomass power plant of Sahacogen Green and Sahagreen Forest to prevent the dust pollutions. This makes the quality of the air emitted from the power plant’s stacks be according to the standards and regulations, as well as safety and environmental friendly.
Key Performance
Noise Pollution Management
- Appropriate design and install the machines and equipment that may cause the noise pollution including eplanning inspection and preventive maintenance. Plant bushy trees surrounding the power plant as green belt for buffering sound and wind that help to control noise level within the standards and regulations.
- Appropriate design and install the machines and equipment that may cause the noise pollution including eplanning inspection and preventive maintenance. Plant bushy trees surrounding the power plant as green belt for buffering sound and wind that help to control noise level within the standards and regulations. Designate 3 check-points for measuring the noise level; the sources of noise in the power plant, the control room of the power plant and the boundaries of the power plant. The noises are controlled within the standards and regulations, with routine measuring the noise level in every 3 months. Provide ear muffs for employees to wear when working in areas with noise level exceeding 80 Decibels. Employees are required to wear the ear muffs when working in that areas which warning signs were installed to remind them of this regulation.

Waste Management
Ratch Pathana Group is dedicated to manage waste according to the legal standards and the policies of each power plant. Wastes are divided into two categories: hazardous waste and non-hazardous waste. The company’s waste management practices are as followings :
- Hazardous wastes are those that can be harmful to the environment, such as transformer oil, lubricants and chemical containers. These wastes are disposed according to the approved procedures to the agencies authorized by the Department of Industrial Works.
- Non-hazardous wastes are general wastes such as leftovers, wood, paper, wires, plastic bags, and constructionmaterials. These wastes are classified before disposing to bury according to the standards and regulations or appropriately recycling. The waste bank project was established to purchase recyclable wastes from employees in order to foster employees to utilize resources effectively.

Water Related Risks
Water is an essential resource in electricity generation. As climate change increases water risks, either drought or food, this presents a challenge for new and existing power plants. In 2024, Ratch Pathana Energy prepared the water risk assessment process as part of the ESMS, using it as a decision-making tool and the basis for control or management measures to minimize risks. The assessment process will be deployed in 2025 onwards.
Measures to tackle water shortage
Operating power plants have assessed water risks from shortage based on the criteria of Water Risk Filter (WWF) and World’s Resources Institute (WRI) Aqueduct. Taken into account are legal requirements, financial aspects, raw water volume, water quality, utilization balance and relevant stakeholders. The results are used as the basis for water management planning.
Water stress assessment and production management
There are 3 sources of water for Ratch Pathana Energy Power Plant are Nong Kho Reservoir Dok Krai Reservoir and Bang Phra Reservoir.
In 2023, the Bang Phra Reservoir is primary source (0.00342% of 100% Reservoir) and the Nong Kho Reservoir and the Dok Krai Reservoir are second source of Ratch Pathana Energy were found to have high water stress level (at 40-80%)
Power plants’ measures and approaches to tackle water risks
- Ratch Pathana Energy Power Plant in Chonburi Province used raw water from the Dok Krai Reservoir, the Nong Kho Reservoir and the Bang Phra Reservoir under 5-year and 10-year supply contracts, respectively.
- Each power plant required tap water producers to prepare secondary and emergency water sources in case of drought or water shortage, to ensure sufficient resources for power generation.
- Reserve ponds or secondary storage system were in place for at least 30 days of internal use.
- Water quality improvement systems were installed.
- Water cycles in the cooling system were maximized, to reduce water withdrawal.
- Water reuse cycles for internal use were optimized, e.g. reusing RO-treated water in the production process or using rainwater or treated wastewater in the production, cleaning and tree watering.
- Water pipelines were regularly inspected to prevent water leakage and loss.
