Gaojia Optics integrates environmental protection into every step of its production process—selecting low-pollution materials that meet RoHS and REACH standards, with some products made from recyclable or biodegradable materials. Our Vietnam facility features advanced wastewater recycling and multi-stage exhaust gas treatment systems to ensure 100% compliant emissions. By adopting energy-efficient equipment and intelligent management systems, we are driving a green transformation in manufacturing—proving that sustainable development and high-quality production can go hand in hand. We offer optical products that deliver both performance and environmental value.
In the optical manufacturing sector, “environmental protection” is not just a slogan—it’s a commitment to the future. At Gaojia Optics, we view environmental responsibility as a core competitive advantage. From material selection to process design, from equipment upgrades to workflow optimization, every step of our production follows a green manufacturing philosophy, making sustainability an integral part of lens quality.
1. Rigorous Material Selection: Safeguarding a Greener Future at the Source
We believe true environmental protection starts with materials. Our procurement process follows stricter criteria than industry norms:
Compliance with international standards: We use 100% low-pollution materials that comply with RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals), eliminating harmful substances like lead and mercury to ensure product safety.
Sustainable innovation: For high-end projects, we prioritize the use of recyclable optical glass and biodegradable coating solvents—reducing long-term environmental impact while maintaining high light transmittance (≥97%@550nm) and optical stability.
2. Zero-Tolerance Emissions: Building a Closed-Loop Green Production System
At our Vietnam manufacturing base, we have implemented a comprehensive pollution control framework:
Wastewater recycling: With advanced triple filtration and reverse osmosis systems, we recycle 95% of wastewater, reducing water consumption by approximately 50,000 tons per year. Discharge quality consistently exceeds national environmental standards.
Efficient exhaust treatment: Our facility is equipped with multi-stage activated carbon absorption and catalytic combustion units, keeping VOC (volatile organic compound) emissions below 10mg/m³—well below industry averages and ensuring clean air in the production area.
3. Smart Energy Efficiency: Empowering Sustainability Through Technology
Through technological upgrades and management innovation, we continuously lower our energy consumption:
Equipment upgrades: We deploy energy-efficient injection molding and coating machines that consume 30% less power than conventional models. Smart climate control systems optimize production conditions and reduce energy waste.
Process optimization: With MES (Manufacturing Execution System) for real-time monitoring, we improve production scheduling and equipment utilization. Simultaneously, we drive waste classification and reduction initiatives—cutting over 20 tons of solid waste emissions annually.
Upgraded Customer Value: Full Lifecycle Green Solutions
We offer comprehensive environmental solutions for ESG-focused clients—covering product design, production, and end-of-life recycling—to help them achieve sustainability goals throughout the product lifecycle.
