From R&D to Manufacturing—Comprehensive Waste Reduction for High-Efficiency, Eco-Friendly Production

As a production base specializing in colorants and electronic chemicals, Everlight Chemical’s Plant IV not only pursues product performance and market competitiveness but also faces the challenges of pollution control and energy management.  From its inception, the plant was established with the vision of becoming a green factory.  It has adopted solvent-free raw materials, implemented material recycling systems, and continuously driven innovation in process management to develop technologies that significantly reduce pollution and energy consumption.  Whether in PUR adhesives, light-shielding adhesives, grinding fluids, or wastewater treatment, Everlight Chemical embodies the 12 Principles of Green Chemistry through tangible achievements—making environmental protection more than a slogan, but an integral part of daily operations at every stage.

Solvent-Free Formulations to Reduce VOC Emissions, and New Light-Shielding Adhesive Options for Plastic Reduction

In traditional industrial adhesive applications, commonly used PUR adhesives typically rely on organic solvents such as DMF, posing potential risks to both operators and the environment. Everlight Chemical has successfully developed solvent-free PUR systems, significantly reducing VOC emissions and dependence on petrochemical-based raw materials, while actively adopting bio-based and recycled green materials. According to statistics, this product reduces carbon dioxide emissions by 40 metric tons and lowers VOC generation by approximately 200 metric tons annually. In 2024, it was granted a Taiwan patent for its bio-based PUR formulation (TWI836831B), marking a representative achievement in combining high performance with environmental responsibility.

In the field of light-shielding adhesives, Everlight Chemical introduced two products, IBR and IPR, to replace traditional plastic masking materials, achieving both plastic and carbon reduction goals. These innovative adhesives not only reduce VOC emissions by 10 metric tons but also replace single-use adhesive tubes with a refillable supply system. By switching from disposable 30 ml tubes to 1 L adhesive bottles, the usage cycle was extended by more than 30 times, reducing discarded packaging waste by 90%. This improvement not only enhances operational efficiency on production lines but also alleviates environmental burdens. In addition to securing a patent (TW1700341B), the product was awarded the highest honor—the Gold Award—at the 33rd Taiwan Excellence Awards.

These advancements stem from Everlight Chemical’s commitment to rethinking the entire product life cycle. Beyond offering functional products, the Company incorporates environmental considerations into packaging, operation, and usage stages. This integrated design philosophy ensures that green chemistry becomes an essential part of daily production practices, embedded in every aspect of factory operations.

Grinding Fluid Recycling and Wastewater Treatment without Sludge Generation

To further enhance resource utilization, Everlight Chemical has introduced a collaborative recycling model for silicon carbide grinding fluids. Instead of disposing of used grinding fluids, the plant regenerates and processes them internally before sending them back to clients for reuse. This approach successfully reduces both water consumption and waste disposal costs. Estimates indicate that recycling and reprocessing the fluid three times can reduce waste generation by 2.5 metric tons and save approximately 500 metric tons of water resources, offering an effective solution to ease environmental burdens.

In terms of wastewater treatment, conventional processes such as coagulation, biological treatment, and chemical oxidation often require significant space, incur high operational costs, and generate large amounts of sludge. To address these challenges, Everlight Chemical implemented an “Ozone Catalytic Wastewater Treatment System” that utilizes ozone and catalysts to produce highly reactive hydroxyl radicals, effectively breaking down pollutants and increasing COD removal efficiency by more than threefold. Importantly, this system generates no sludge during treatment, requires minimal installation space, and incorporates an intelligent control system to reduce manpower demands—achieving a balance between treatment performance and operational efficiency.

These initiatives are not isolated equipment upgrades but reflect a comprehensive environmental management strategy. From water resource recycling to automated treatment systems, Everlight Chemical integrates various green technologies to build a highly efficient, sustainable manufacturing environment.

From Verification to Knowledge Sharing: Fostering a Green Production Culture

Technical innovation is never easy. Beyond internal system upgrades and material challenges, the greater obstacle often lies in securing recognition and adoption across the external supply chain. For example, when promoting its light-shielding adhesives, Everlight Chemical spent three to four years working with upstream and downstream partners in the display industry to complete product validation and substitution. This process involved repeated testing and adjustments to persuade a mature market to embrace new materials. Such persistence enabled the successful introduction of automatic coating technologies, further reducing labor demands and material waste.

Moreover, Everlight Chemical extends its green chemistry practices beyond internal applications, actively promoting cross-sector collaboration. Initiatives include producing public educational materials with the Taiwan Association for Online Education Development and partnering with Tamkang University to support the “Chemistry Truck” program, bringing environmental material awareness and green technology concepts to elementary schools, middle schools, and local communities—nurturing environmental consciousness among the next generation.

Additionally, the Company continues to support green chemistry promotion projects, research paper awards, and participates in exchanges with organizations such as the Chemical Society Located in Taipei. Through these academia-industry partnerships, Everlight Chemical seeks to inspire more scientists and industry peers to engage in the research and application of green chemistry. This diffusion model ensures that green chemistry is no longer the achievement of a single company, but a collective direction for the entire industry.
