Implementing Green Chemistry Principles

Everlight Chemical implements the 12 Principles of Green Chemistry throughout the product life cycle to minimize adverse environmental impacts and prevent harm to human health.

▍Product Life Cycle – Applying Green Chemistry Principles at Every Stage

Raw Material Selection and Usage

Target
Select sustainable, environmentally friendly, and legally compliant materials.

2024 Case Study
1. Bio-based solvents used in polyimide photoresists.
2. Plant- and E. coli-based adhesives reduce petrochemical reliance.
3. Low-temperature resins selected to save energy.
4. Low-VOC resins used in toner to cut emissions; rice bran wax applied in development.

Compliant Green Chemistry Principles
●Low toxicity  ●Renewable  ●Waste-Prevention  

Raw Material Transportation

Target
Ensure safety and proper handling of materials during transportation.

2024 Case Study
Manage the storage and safe use of chemicals within the plant in accordance with Safety Data Sheets (SDS).

Compliant Green Chemistry Principles
● Hazard Awareness

Manufacturing

Target
Maintain product quality while minimizing environmental impact.

2024 Case Study
1. Low-temperature baking reduces energy use in electronic chemical production.
2. Dual-feed system enables in-process material recycling.

Compliant Green Chemistry Principles
●Exhaustive ●Renewable ●Energy Saving ●Low Toxicity   ●Waste Preventing

Product Packaging

Target
Use recyclable packaging materials and reduce the use of single-use packaging.

2024 Case Study
1. Packaging is labeled with internationally recognized recycling codes to support customer sorting.
2. Promoted packaging reuse with domestic customers and bulk deliveries, cutting material use – e.g., large-capacity toner packaging reduced plastic waste over 30 times.
3. Adopted FSC-certified cartons with 100% recycled inner liners and up to 70% recycled outer layers.
4. Optimized packaging selection and encouraged customers to reuse packaging through active communication.

●Renewable  ●Waste Preventing

Product Transportation

Target
Ensure safe transportation, reduce carbon emissions, and achieve on-time delivery.

2024 Case Study
1. Replaced diesel forklifts with electric models for loading operations to reduce energy use and emissions.
2. Improved transport efficiency through cargo consolidation and maximized loading.
Marine Transport:
-Maximized container loading to fully utilize space and improve efficiency.
-Consolidated goods from different business units for joint shipments, reducing carbon footprint.
-Selected the nearest container yards and ports to shorten transport distance.
-Centralized bulk shipments to further enhance efficiency.
Land Transportation (Taiwan):
-Optimized delivery routes in northern Taiwan based on customer location to minimize distance.
-In central and southern Taiwan, worked with carriers to use return trips and avoid empty runs.
-Used recycled pallets from raw material suppliers to reduce the need for new pallets.

●Renewable  ●Energy Saving  ●Waste Preventing

Product Use

Target
Offer high efficiency UPE products that reduce environmental impact during use.

2024 Case Study
The Everclear series dyes reduce dye usage by 40%, save 40% of water resources, and lower carbon emissions by 72%.

Compliant Green Chemistry Principles
●Energy Saving  ●Waste Preventing

End-of-Life Management for Products and Packaging

Target
Minimize environmental impact through proper disposal and product recycling.

2024 Case Study
1. Dispose according to the SDS instructions or applicable national regulations.
2. Increase packaging recycling rates and reduce waste generation.

▍Chemical and Packaging Material Recycling

To align with Green Chemistry’s principles of regeneration and maximum resource utilization, the Company has tracked chemical and packaging material recycling over the past four years. In 2024, the pharmaceutical business unit significantly improved its solvent recycling rate from 8% to 48%. However, the overall Company chemical recycling rate remained between 0.5% and 1.1%, reflecting challenges in other business units.

Packaging recycling has been more stable, with recovery rates exceeding 80%, especially for bulk bags, one-way drums, and plastic bags – demonstrating real progress in circular economy practices.
