Raw Materials Management
Raw Material Management & Circular Economy
Aluminum is the primary raw material for SAI’s products. Guided by the sustainable mindset that “Resources are finite, but circulation is infinite,” SAI focuses on resource circularity to reduce waste generation and carbon footprint. Through process R&D, we transform scrap parts, machining chips, and offcuts generated during production into high-quality secondary aluminum.
Leveraging process R&D and advanced remelting technologies, SAI’s closed-loop aluminum recycling system is strategically expanding from Post-Industrial Recycled (PIR) to Post-Consumer Recycled (PCR), steering the aluminum industry toward net-zero targets:
Post-Industrial Recycled (PIR) | RESAICAL® 100% Recycled Aluminum
By fully (100%) recovering and remelting scrap parts, machining chips, aluminum blocks, and offcuts generated during manufacturing into high-grade secondary aluminum, SAI established the certified recycled aluminum brand RESAICAL®. In 2025, SAI achieved a recycled aluminum usage rate of 36.93%, with strategic targets set at ≧50% by 2026 and ≧55% by 2030.
Post-Consumer Recycled (PCR) | CIRCULIUM Circular Aluminum Brand
To further expand environmental impact and respond to global brands’ demands for product lifecycle management, SAI is advancing into the Post-Consumer Recycled (PCR) domain with the launch of CIRCULIUM, a next-generation circular aluminum brand. By extending the recycling scope to end-of-life consumer products, SAI unlocks an infinite material lifecycle to forge a greener and more sustainable low-carbon future.

Greenhouse Gas Emissions and Energy Management
In response to the global trend of zero emissions, we produce statistics on GHG emissions with simple assessment: In 2025, various energy conservation and carbon reduction initiatives resulted in approximately 711,360 kWh of electricity savings and a reduction of 337.185 tCO2e in greenhouse gas emissions.
SAI has invested NT$66.8 million in establishing a 1,492.4 kW solar power generation facility at its Pingtung Plant to supply the facility’s internal energy needs, with an average annual generation capacity of approximately 1.85 million kWh.
Value Water
We deeply understand the importance of saving water. The water risk assessment map shows that Plant I, Plant H, Plant 2, Chuwei Plant, Pingtung Plant are not located in the high water risk areas. Our management measures for water consumption are as follows:
Check tap water consumption every day and make immediate improvement for abnormal water consumption.
Reuse cleaner rising water spill from the water tanks at the equipment washing line.
Periodically maintain the cooling towers to maintain efficiency.
Reclaim pure water for reuse to reduce tap water consumption.
Water Resource Management Targets:
1. Maintain total water withdrawal below 700 thousand cubic meters (<700 thousand m^3)
2. Achieve a wastewater recycling rate of ≧ 20% at Yunlin Plant
Use water-efficient taps and toilet flushes.
Process wastewater and employee sewage are the major sources of wastewater of Yunlin Plant and Pingtung Plant. In accordance with the Water Pollution Prevention Act, wastewater is treated at the in-house wastewater pre-treatment facilities before being discharged to the wastewater treatment plant of the industrial park through the sewerage system.
The in-house wastewater treatment equipment include the drum screen, equalization tank, pH correction tank, electrocoagulation system, sedimentation tank, aeration tank, and outfall system. Monitoring equipment is also equipped to monitor water quality each day.
Waste Management
Both general waste and hazardous industrial waste are produced from the operational process. We have established the Waste Management Procedures for effective management to achieve the goal of waste reduction. To ensure that waste is legally removed and disposed, we visit the disposal plant with the waste dumping truck from time to time and periodically audit waste disposal plants every year.
Daily
- Issue the waste disposal three-copy order
- Audit the legal compliance of the disposal process
Weekly
- Check the GPS records of the dumping trucks.
- Consolidate disposal records
Monthly
- Trace the flow and progress of waste handling.
- Report the waste storage and production records
Aluminium Stewardship Initiative
Since officially obtaining certification under the ASI (Aluminium Stewardship Initiative) Performance Standard V3 (2022) in July 2023, SAI has continued to deepen its participation in a responsible aluminium value chain, embedding “sustainability” into the core of its corporate strategy and implementing end-to-end management and
monitoring — spanning raw material procurement, manufacturing, and product output — in order to fulfill its commitment to responsible production. At the same time, in response to the trend toward vehicle electrification, SAI is actively exploring and developing diverse application possibilities for forged aluminium, while enhancing resource circularity through recycled aluminium smelting technology, in an effort to expand the application value of aluminium in sustainable manufacturing and low-carbon transition, and to maximize the contribution value of aluminium.
