The glass sector produces beautiful, durable products that are recyclable forever, yet the energy‑intensive furnaces used in conventional production contribute roughly 2.6 % of global industrial CO₂ emissions. At the same time, consumer expectations are rising – a 2025 McKinsey survey found that 77 % of Americans ranked recyclability as extremely or very important when choosing packaging, and glass was rated the most sustainable materia. This tension between environmental impact and market demand sets the stage for a pivotal year. In this post I explore what 2026 will bring in the glass manufacturing industry and why GMIC members are at the forefront of change.
GMIC’s mission
As the trade association for America’s glass producers, suppliers and researchers, the Glass Manufacturing Industry Council (GMIC) advocates for technology development, workforce training and sustainability. The Council’s mission is to promote the interests of the industry through innovation, productivity and environmental cooperation. Asking “What will 2026 bring in the Glass Manufacturing Industry?” is therefore not idle speculation – it guides investments in furnaces, recycling infrastructure and workforce skills that will shape our members’ competitiveness.
Market momentum – growth drivers and forecasts
The market outlook provides some context. Research Nester projects that the global glass manufacturing market, valued at about USD 192.99 billion in 2025, will surpass USD 202.37 billion in 2026 and exceed USD 326.54 billion by 2035 with a compound annual growth rate of 5.4 % (researchnester.com). Container glass could grow by 45 % by 2035 thanks to demand for eco‑friendly packaging (researchnester.com). The research notes that the Asia‑Pacific region is expected to capture around 40 % of global demand, while North America will hold the second‑largest share (researchnester.com). Drivers include infrastructure investment, urbanization, automotive glazing, renewable energy installations, and consumer preferences for recyclable packaging (researchnester.com).
The automotive segment alone is projected to expand from USD 22.35 billion in 2025 to around USD 29.21 billion by 2030 due to electric mobility, panoramic roofs and safety glazing (mordorintelligence.com). Float glass and specialty glass will gain share as energy‑efficient windows, solar modules and digital devices proliferate (industryarc.com). Market growth, coupled with policy incentives such as the U.S. 30 % solar tax credit, means our members see opportunity – but it will hinge on adopting sustainable practices.
Decarbonizing through hybrid and electric melting
One of the most significant shifts I expect by 2026 is the rapid deployment of hybrid and electric melting technologies. Hybrid furnaces combine electric heating with natural gas to cut emissions and improve efficiency. GMIC members like Libbey and Ardagh Glass Packaging are leading the way. Libbey is replacing four regenerative furnaces with two hybrid electric furnaces at its Toledo, Ohio plant, a move expected to reduce carbon emissions by roughly 60 % and leverage up to 80 % renewable electricity. Ardagh’s NextGen hybrid furnace in Germany uses about 60 % electric heating, producing up to 350 tons/day and achieving a 64 % reduction in carbon emissions per bottle; the furnace saved 35,000 tons of CO₂ in its first year and targets a 69 % reduction as the share of renewable electricity increases (theclimatedrive.org).
. Fully electric furnaces are also emerging; Schott and Heinz‑Glas have already installed them, while Proco Group notes that regulatory pressures, growing circular‑economy demand and financial incentives are driving adoption. However, grid capacity and infrastructure remain challenges.
The U.S. Department of Energy (DOE) and GMIC are collaborating on a transformative “Advanced Electric Melting to Decarbonize Commercial Glass” project. Launched in late 2024, this project aims to demonstrate electric melting processes that can reduce scope‑1 greenhouse‑gas emissions by more than 85 %. Early results show that high levels of recycled glass (cullet) – around 70 % of the batch – reduce emissions and energy use but present technical challenges like foaming during cold‑top electric melting. Computational fluid‑dynamics modeling with CelSian’s GTM‑X software is being used to optimize furnace designs, with the ultimate goal of making electric melting viable for dark‑colored and clear glasses alike.
Energy efficiency and AI – squeezing more from existing assets
Even before new furnaces come online, plants can cut emissions through better process control. Energy costs can represent up to 14 % of total glass production expenses, so incremental savings make a big difference. CelSian – a GMIC member – offers advanced furnace modeling (GTM‑X) and training programs that help operators identify inefficiencies, optimize combustion and reduce fuel consumption. The DOE’s ISEED program is supporting CelSian’s Oxy‑Fuel and Sustainable Furnace Operations courses, which emphasize hands‑on learning and drive adoption of energy‑saving practices.
Artificial intelligence (AI) is also poised to transform glassmaking. According to GMIC’s 2025 article on AI, machine‑learning systems can optimize furnace controls, adjust parameters in real time and predict maintenance needs to reduce fuel waste. For example, O‑I Glass installed an AI‑powered energy management system in the United Kingdom that, when paired with battery storage, is projected to save 240 tons of CO₂ annually. Machine‑vision tools can inspect glass for bubbles or scratches and adjust production conditions to minimize scrap, while AI‑enabled sorters enhance recycling by identifying glass color and composition. The article notes that a 10 % increase in cullet usage can deliver roughly 3 % energy savings and 7 % fewer emissions.
Recycling, circularity and lighter packaging
Glass’s key sustainability advantage is its infinite recyclability, yet U.S. recovery rates hover around 30 % GMIC members are working to change that. Gallo Glass diverts nearly 175,000 tons of glass from landfills each year and buys more than 20 % of all recycled glass in California. Bottles produced at its Modesto plant contain up to 75 % recycled glass, roughly 45 % from post‑consumer sources. The company also developed lightweight 14‑ounce wine bottles that reduce material usage, shipping emissions and energy consumption. It recently designed equipment that enables reuse of “three‑mix” cullet – material previously considered unrecyclable. Gallo’s combination of local cullet sourcing and advanced predictive‑control furnaces highlights how circularity can boost both sustainability and competitiveness.
Consumer attitudes reinforce this trajectory. The McKinsey survey highlighted above found that Americans view glass as the most sustainable packaging material and expect brands to take responsibility for recyclability. This underscores the strategic importance of cullet processing technologies, deposit return schemes and design for recycling. In addition, the International Finance Corporation reports that each 10 % increase in cullet can cut energy use by about 3 % and carbon emissions by 7 %, and the recycled‑glass market could reach USD 5.5 billion by 2025 (ifc.org). I expect 2026 to see greater collaboration between municipalities, beverage companies and GMIC members to raise recycling rates and meet consumer expectations.
Collaborative programs and workforce development
The DOE’s Better Plants program exemplifies collaborative action. It provides technical assistance, peer learning and recognition for companies that commit to reducing energy intensity. GMIC members such as Acuity Brands, CertainTeed (Saint‑Gobain), Owens Corning, Vitro Architectural Glass, Imerys and Siemens participate, leveraging the program to optimize manufacturing processes and lower energy use. These partnerships help disseminate best practices across the industry and prepare the workforce for modern, digitalised glass plants.
Workforce development is central to GMIC’s mission. Through the Glass Problems Conference and GlassTrend Symposium, members exchange technical insights and explore emerging technologies. In 2025 the Council recognized leaders such as Dr. Alexis Clare for advancing glass science, Neil Simpson for his groundbreaking combustion burners, and Victor Camacho for operational excellence. Celebrating these achievements highlights the importance of mentorship and technical education as we transition to new melting technologies.
Product innovation and digitalisation
Beyond furnaces, product design is evolving. Guardian Glass recently launched a low‑carbon float glass line called “Nexa,” which uses more cullet and reduces embodied carbon by over 30 % compared with standard float glass. Vitro Architectural Glass updated its environmental product declaration and achieved a global warming potential of 1,240 kg CO₂e per tonne, making it one of the lowest‑carbon flat glass products available (usglassmag.com). Innovations like smart coating technologies, energy‑saving insulated units and architectural glass that dynamically tints in response to sunlight will gain prominence as building codes demand better thermal performance. The rise of AI‑enabled design tools and digital twins will accelerate product development and reduce time to market.
Looking ahead: What will 2026 bring in the Glass Manufacturing Industry?
By now it should be clear why I keep returning to the question “What will 2026 bring in the Glass Manufacturing Industry?” In my view, 2026 will mark a tipping point where decarbonization technologies move from pilot projects to commercial scale. Hybrid furnaces will be installed at more plants, electric melting research will mature, and AI will become a standard tool for optimizing energy use and quality. Recyclability will shift from a marketing claim to a business necessity as deposit‑return programs expand and consumers demand transparency. Collaborative programs like Better Plants will continue to spread best practices, while new training initiatives prepare the workforce for data‑driven manufacturing. Companies that embrace these trends – like Libbey, Ardagh, Gallo, Corning, Guardian and CelSian – will define the industry’s future.
Finally, the adoption of low‑carbon product lines and digital design tools will help architects, automakers and tech companies meet stricter sustainability standards. The glass sector’s growth prospects remain bright, but success hinges on the willingness of manufacturers to innovate and collaborate. As a member of the GMIC community, I’m energized by the progress we’ve already made and confident that 2026 will be a milestone year in our journey toward a resilient, circular and low‑carbon glass industr
Finding the right job in glass manufacturing requires understanding a complex industry, building practical skills and using modern job‑search tactics. The Glass Manufacturing Industry Council (GMIC) represents the U.S. glass sector and works with employers and educators to build a skilled workforce. As automation, sustainability and digitalization reshape production lines, qualified workers are in high demand. According to the U.S. Bureau of Labor Statistics, employment of glaziers—the tradespeople who install glass in buildings—is expected to grow about 3 % from 2024 to 2034, with roughly 5 100 openings per year as experienced workers retire. The broader “glass and glass product manufacturing” industry employs about 129 000 people in the United States, so there is ample room for newcomers to join.
