2025 Pollution and Resource Management Performance Summary
Through the continuous implementation of its Green Process policy, the Company has consolidated the outcomes of its pollution and resource reduction initiatives across all operational dimensions, as summarized below.
| Sources of Pollution and Resource Reduction | Project Scope | Reduction Achieved / Results |
|---|---|---|
| 1. Through Advanced Pollution Control Technologies |
Air: Installed dust collection systems (Multi-Cyclone, Wet Scrubber, and Bag Filter) and odor control systems. Water: Treated wastewater using the Activated Sludge (AS) system and recirculated water within the cooling system. |
Reduced Water Intensity 31.1% Air Emissions and Wastewater Quality Complied with Regulatory Standards 100% Zero Odor Complaints |
| 2. Through Circular Economy and Zero Waste Initiatives |
Implemented projects based on the 3Rs principles (Reduce, Reuse, Recycle). Upcycling: Converted used noodle packaging into recycled composite boards. Take-back: Collected and returned film cores and sauce containers for reuse, and returned red plastic bags to manufacturers for recycling. |
Reduced Waste Intensity 0.35% Volume of Waste Recycled or Recirculated 14,437.47 tons Towards Zero Waste to Landfill by 2030 |
| 3. Through Energy Management and Climate Change Strategies |
Production Efficiency and Clean Energy Implemented frying optimization to improve process efficiency and applied a Steam Ejector system to reduce steam consumption. Generated renewable electricity from solar energy to replace grid electricity consumption. Implemented preventive maintenance practices to reduce energy losses and improve operational efficiency. |

Water Consumption Reduction Summary
Through the continuous implementation of its Green Process policy, the Company has consolidated the outcomes of its pollution and resource reduction initiatives across all operational dimensions, as summarized below.
| Water Management Strategy | Project Scope and Key Measures | Outcomes and Benefits |
|---|---|---|
| 1. Water Reduction at Source Focusing on machinery and workflow optimization to minimize water usage while maximizing purity. |
• High-Pressure Water: Replacing hoses with high-pressure water washers in the noodle production lines. • Spray Nozzle: Replacing perforated pipes with spray nozzles in the noodle conveyor and filtration systems to improve water distribution and efficiency. • Automated Systems: Installing roller soaking tubs instead of continuous spraying, and implementing automated screen washing systems (using non-hazardous chemical alternatives instead of water/steam). |
Reduction in Water Consumption per Unit of Product 31.1% Production efficiency: Reduced cleaning and maintenance downtime. Reduction in wastewater sent for treatment. |
| 2. Water Recirculation and Reuse Reusing treated water or utility wastewater to maximize cost-efficiency and value. |
• Reusing treated wastewater for non-contact activities, such as watering green spaces, flushing toilets, and operating odor scrubber systems. • RO Reject and Process Wastewater Recovery Project • Steam Condensate Recovery Project for Boiler Feedwater |
Reduction in freshwater withdrawal from natural sources Reduction in municipal and groundwater consumption Energy savings Maximizing energy efficiency by recovering high-temperature condensate, reducing the fuel required to heat boiler feedwater. |
| 3. Continuous Efficiency Improvement Systemic Management, Scaling, and Governance |
• Water Consumption Tracking: Reporting water use by category at working committee meetings and monitoring wastewater treatment system performance monthly. • Scaling successful initiatives from the pilot plant to other branches, such as implementing water recycling at the Lamphun branch and steam condensate recovery at the Rayong branch. • Future Initiative: Water reduction equipment upgrade for noodle steamers (Ban Pong 1 Plant) |
Sustainable Management • Establishing an accurate water consumption database for advanced analytics. • Standardizing practices to ensure operational consistency across all plants. |
