European glass plants are closing while new hybrid furnaces are opening because producers are concentrating lower demand into fewer, more efficient sites. Weak demand has left some older capacity underused. At the same time, energy costs and long-term investment plans are pushing producers to upgrade the sites they expect to keep.
These two trends do not show that Europe is abandoning glass packaging. They show that the industry is changing where and how it produces glass bottles.
The main shift is from maintaining every existing furnace to choosing which plants deserve new investment. Some sites will lose capacity. Other sites will receive hybrid furnaces, heat recovery systems and new production lines.
What Is Happening to European Glass Production Capacity?
Several large glass producers adjusted their European production networks during 2026.
Ardagh Group confirmed that its Germersheim facility in Germany will close during the third quarter of 2026. The company said the decision would address challenging demand conditions and bring its capacity closer to current market needs. The closure is part of Ardagh’s wider “Clearly Ardagh” turnaround plan, according to its second-quarter 2026 results.
The Germersheim plant is not a small warehouse or finishing site. Industry reporting states that the plant produces just under two million glass containers per day and employs around 260 people. The site mainly serves beverage bottle markets. This scale makes the closure a meaningful reduction in German production capacity.
Ardagh is not the only producer making this type of adjustment. Verallia closed its Essen plant in Germany in March 2026. The company also stopped a furnace at Châteaubernard in France and another at Knottingley in the United Kingdom. Verallia described these actions as a response to excess capacity in the European market in its 2026 first-half results.
However, Verallia restarted a more efficient furnace in Leeds while stopping older equipment elsewhere. This detail is important. Producers are not simply removing every available tonne of capacity. They are moving production towards plants that offer better efficiency, location or long-term value.
Why Are Some European Glass Plants Closing?
Some European glass plants are closing because demand has fallen below the capacity installed during stronger market periods. The decline is especially clear in wine, sparkling wine, cognac and some spirits markets.
Verallia reported that European glass packaging volumes contracted sharply in 2023 and remained below 2019 levels. The company linked this change partly to a 4% decline in European alcohol consumption since 2019. Verallia also pointed to weaker exports from its customers to the United States and Asia in its European industrial footprint announcement.
The decline is not equal across every glass packaging category. A producer can experience weak wine bottle demand while food jar or spirits bottle volumes remain more stable. Regional conditions also differ. A plant in Germany may have low utilisation while a site serving Spain or another market still needs more capacity.
Glass production also has high fixed costs. A large furnace, its forming lines and its supporting equipment require major investment and continuous operation. A plant becomes less competitive when its output remains below the level needed to cover those costs.
A producer may therefore close one site and transfer its customers to another plant. This decision can reduce unused capacity without ending supply to the affected customers.
Why Are Hybrid Glass Furnaces Opening at the Same Time?
Hybrid glass furnaces are opening because producers still need reliable production at the plants they plan to keep. A furnace closure at one location does not remove the need to rebuild aging furnaces elsewhere.
A conventional glass furnace relies mainly on fossil fuel to melt raw materials and recycled glass. A hybrid furnace uses both fuel and electricity. The operator can adjust the energy mix according to the furnace design, electricity supply and production needs.
The word “hybrid” does not describe one fixed system. Different projects use different shares of electricity, natural gas, biofuel or oxy-fuel combustion.
Verallia inaugurated its first hybrid furnace in Zaragoza, Spain, in April 2026. The company invested €63 million in the project. The furnace uses 70% renewable electricity and 30% natural gas or biofuel. It has three production lines and can produce different glass colours.
The investment will also raise the total output of the Zaragoza site, which operates two furnaces, to 1.3 million containers per day at full capacity. Verallia said the project supports demand from wine, spirits and beverage customers in the Spanish market. The company published the project details in its Zaragoza hybrid furnace announcement.
O-I also produced the first glass from its new hybrid furnace in Veauche, France, in June 2026. O-I originally announced an investment of approximately $65 million for the plant’s electrification and modernisation. The furnace can use between 30% and 70% electricity. O-I also added heat recovery and air preheating systems to the site.
The Veauche project replaced one of the plant’s existing furnaces. It did not create a completely new glass factory. This type of replacement allows O-I to keep production at a strategically located plant while changing the technology used to melt the glass. The original specifications are available in the O-I project announcement.
More hybrid projects are also moving forward in France. Verallia is replacing an existing furnace at Saint-Romain-le-Puy with hybrid technology. Verescence is working with Fives to replace an existing furnace at Mers-les-Bains. The Verescence furnace will produce up to 150 tonnes of glass per day for perfume and cosmetic bottles and can replace up to 80% of its fossil fuel use with electricity.
These projects again show that much of the investment involves replacing selected furnaces rather than adding entirely new factories.
Why Are Plant Closures and Furnace Investments Not Contradictory?
Plant closures and hybrid furnace investments are two parts of the same industrial strategy. Producers are reducing capacity where demand no longer supports a full plant. They are investing where production is expected to remain useful for many years.
A new furnace does not always mean that the company expects a large increase in total European glass bottle demand. Many furnace projects replace equipment that has reached the end of its operating life.
The location also matters. A plant near key customers, recycled glass supplies and suitable energy infrastructure can be more valuable than an older plant with weak local demand. Producers may move bottle production between sites even when their total European capacity falls.
The available announcements suggest that European glass production is becoming more concentrated. The industry will probably operate fewer low-use assets while directing more capital towards selected modern plants.
This change can improve efficiency, but it also makes individual production sites more important. A delay, repair or supply problem at a major plant may affect more customers when production is concentrated into a smaller network.
How Do Hybrid Furnaces Affect Carbon Emissions?
Hybrid furnaces can reduce emissions when electricity replaces part of the fossil fuel used for melting. However, each reduction figure applies only to a specific furnace, energy mix and calculation boundary.
Verallia expects its Zaragoza furnace to reduce Scope 1 and Scope 2 CO₂ emissions by around 50%. The company states that the reduction could reach 60% depending on the energy mix.
O-I expects its Veauche hybrid technology to reduce on-site CO₂ emissions by approximately 43% when the furnace operates at an average electricity level of 50%.
These figures should not be applied to every hybrid furnace. A plant that uses low-carbon electricity may achieve a different result from a plant that relies on electricity generated from fossil fuels. The percentage also changes when a calculation includes raw materials, recycled glass, transport or other parts of the bottle’s life cycle.
Bottle buyers should therefore check what a carbon claim covers. The buyer should ask whether the figure refers to the furnace, the complete plant, Scope 1 and Scope 2 emissions or the full life cycle of one bottle.
Bottle weight and recycled glass content can also affect the final footprint. Furnace technology is only one part of the packaging calculation.
What Do These Changes Mean for Glass Bottle Buyers?
The closure of one plant does not automatically create a European glass bottle shortage. Large producers can transfer some bottle production to other plants in their networks.
However, a transfer may still change lead times, transport distances and production schedules. A customer may also need to approve bottles made on a different line or at a different plant.
Buyers should confirm the actual production site instead of relying only on the supplier’s company name. The buyer should also ask whether the supplier has another plant that can produce the same bottle, glass colour and neck finish.
Custom bottles require closer review. A custom mould may be stored at one factory and may not be ready for use on another forming line. The buyer should confirm mould ownership, transfer conditions and backup production options before a supply problem occurs.
Buyers who need environmental data should request the calculation method as well as the percentage. A general statement such as “made in a hybrid furnace” does not provide enough information for a formal packaging report.
These checks are especially important for wine, sparkling wine and spirits brands because several recent European capacity changes involve plants that serve alcoholic beverage markets.
الأسئلة الشائعة
Are European Glass Bottle Shortages Likely?
The current closures do not prove that Europe will face a general bottle shortage. Producers are transferring some production and investing in other sites.
Certain bottle types, colours or regional supply routes may still face tighter capacity. Custom bottles can carry more risk because another factory may not have the required mould or production setup.
Is a Hybrid Glass Furnace Fully Electric?
No. A hybrid glass furnace combines electricity with another energy source, such as natural gas, biofuel or oxy-fuel combustion.
The electricity share depends on the furnace design. Verallia’s Zaragoza furnace uses 70% renewable electricity, while O-I’s Veauche system can operate with an electricity share between 30% and 70%.
Does a Hybrid Furnace Produce Better Glass Bottles?
A hybrid furnace does not automatically produce a stronger or clearer bottle. Bottle quality still depends on the glass composition, melting control, forming process, annealing and inspection system.
The main advantages of hybrid technology relate to energy flexibility, efficiency and reduced dependence on fossil fuels.
Will Hybrid Furnaces Make Glass Bottles Cheaper?
Hybrid technology does not guarantee a lower bottle price. These furnaces require large investments, and electricity prices can vary by country and time.
The technology may improve long-term energy efficiency. However, bottle prices still depend on order volume, bottle weight, colour, mould requirements, decoration, packaging and transport.
الخاتمة
European glass plants are not closing because the glass bottle market is disappearing. Producers are closing underused sites, moving production and replacing selected furnaces with more flexible technology.
The result is a smaller or more concentrated production network in some regions, combined with major investment at sites expected to remain competitive. Bottle buyers should watch production locations, backup capacity, mould arrangements and lead times rather than judging the market from one plant closure.
