2025 Pollution and Resource Management Performance Summary
Through the continuous implementation of the Green Process Policy, the Company has consolidated the results of its efforts to reduce pollution and resource consumption 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%
Waste Recovered for Reuse or Recirculation 14,437.47 tons Towards Zero Waste to Landfill by 2030 |
| 3. Through Energy Management and Climate Change Strategies |
Production Efficiency and Clean Energy
• Production Process: Improved frying efficiency through Frying Optimization and the use of Steam Ejectors 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. |
Reduced Energy Consumption
18.4%
Greenhouse Gas Emissions Reduced 3,858.8 tCO2e / Year (Equivalent to planting 385,880 trees)* |
