As a high-performance inorganic nonmetallic material, glass fiber has been deeply integrated into key sectors of the national economy—such as construction, transportation, and electronics—thanks to its core advantages of high strength, lightweight properties, corrosion resistance, and electrical insulation.
As a high-performance inorganic nonmetallic material, glass fiber has become deeply integrated into key sectors of the national economy—such as construction, transportation, and electronics—thanks to its core advantages of high strength, lightweight properties, corrosion resistance, and electrical insulation. With the global energy transition, the upgrading of high-end manufacturing, and the advancement of the “dual carbon” goals, the glass fiber industry is moving away from traditional scale‑expansion models and entering a new phase of high‑quality development centered on high‑endization, green practices, and intelligent technologies, driven by emerging applications as its growth engine.
Green Transformation: Low-Carbon Across the Entire Lifecycle, Driven by Both Policy and Technology
The global “dual carbon” goals and green policy directives are driving the glass fiber industry toward a low‑carbon transformation across its entire value chain, from manufacturing to end‑use applications. On the production side, energy‑saving and consumption‑reducing technologies are being widely adopted; China’s newly issued energy‑consumption limit standards for the glass fiber sector are 22% stricter than the 2020 version. Leading companies have reduced kiln energy use by more than 12% through measures such as biomass fuel substitution, oxy‑fuel combustion, and AI‑driven optimization of combustion parameters. Carbon capture, utilization, and storage (CCUS) technologies convert CO₂ from kiln exhaust into calcium carbonate, enabling “negative‑carbon production”; one domestic zero‑carbon smart manufacturing facility, powered by green electricity, achieves annual carbon reductions exceeding 400,000 tonnes. At the recycling end, challenges in managing glass fiber waste are gradually being overcome: a thermoplastic glass fiber blade‑recycling process uses microwave heating to depolymerize resin, preserving up to 92% of the original fiber strength; while supercritical CO₂ extraction can achieve a 98% resin removal rate, allowing recovered fibers to be remanufactured into wind‑turbine blade cores and reducing life‑cycle carbon emissions by 60%. On the policy front, glass fiber and related product manufacturing has been included in the “Green Finance Support Project Catalog (2025 Edition),” and the European Union’s Carbon Border Adjustment Mechanism (CBAM) is prompting 50% of leading firms to pursue product carbon‑footprint certification, thereby accelerating the industry’s green transition.
Intelligent Empowerment: Upgrading Manufacturing and Services to Enhance Industrial Efficiency and Value
Intelligent technologies have been deeply integrated into the fiberglass industry, driving all‑round upgrades across both production and service models. On the manufacturing side, the scaling up and intelligent optimization of tank furnaces have yielded significant cost reductions: China Jushi’s 600,000‑ton‑per‑year tank furnace, leveraging AI to fine‑tune combustion parameters, has extended the service life of its platinum–rhodium alloy bushings to 18 months. Meanwhile, Shandong Fiberglass has deployed an AI‑based quality‑inspection system that achieves a defect‑detection accuracy of 99.5%, boosting efficiency by a factor of 20 compared with manual inspection. At the product level, “smart fiberglass” is emerging as a key innovation trend. By embedding sensors or conductive fibers within fiberglass fabrics, it becomes possible to monitor in real time the structural health of bridges, wind‑turbine blades, and other critical components, reducing wind‑turbine blade maintenance costs by 30%. In terms of service models, leading industry players are transitioning from mere product manufacturers to comprehensive system‑service providers that integrate materials, processes, and data. By integrating industrial Internet platforms, they enable end‑to‑end traceability throughout the production process; meanwhile, digital twin technology shortens product‑design cycles, allowing them to deliver customized solutions to customers. Furthermore, the standards framework is being rapidly refined: seven new international test standards for fiberglass performance have recently been issued, and China has spearheaded the development of three global standards. Product certification timelines have been cut to 45 days, thereby accelerating the commercialization of new technologies.
