Water Consumption Reduction Summary
Through the continuous implementation of the Green Process Policy, the Company has consolidated the results of its water-use 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 improving machinery and operational practices to reduce water consumption while enhancing cleanliness. |
• High-Pressure Water:
Replaced conventional water hoses with high-pressure water cleaners in the noodle production line.
• Spray Nozzles: Replaced perforated pipes with spray nozzles on rice noodle conveyor belts and filtration systems. • Automated Systems: Installed roller soaking tanks to replace continuous water spraying, along with an automatic screen-washing system. |
Reduce water consumption per unit of product
31.1%
Reduced Cleaning Time Reduction in wastewater sent for treatment. |
| 2. Water Recirculation and Reuse |
• Reused treated wastewater for applications such as watering green areas, toilet flushing, and use in odor control towers.
• Reused wastewater from the RO and water treatment systems for water production. • Recovered condensate from production lines and returned it to the boiler system. |
Reduction in freshwater withdrawal from natural sources
Reduced Tap Water and Groundwater Consumption Reduced Energy Consumption |
| 3. Continuous Efficiency Improvement |
• Monitored water consumption by type and wastewater treatment system performance on a monthly basis.
• Expanded successful practices from the pilot factory to other factories. • Plan to upgrade water-saving equipment for the rice noodle steamer at Ban Pong 1 Factory. |
Database for Analysis
• Standardizing practices to ensure operational consistency across all plants. |
