The European Union’s Packaging and Packaging Waste Regulation (PPWR), which took effect on February 11, 2025, aims to reduce packaging waste and promote a circular economy.
This regulation mandates that all packaging be recyclable by 2030, with specific targets for waste reduction: a 5% decrease by 2030, 10% by 2035, and 15% by 2040, using 2018 as the baseline.
The alcohol industry, which is heavily reliant on single-use packaging, stands at the forefront of this challenge. While glass bottles are celebrated for their premium appeal and recyclability, their production and transport are resource-intensive, contributing significantly to carbon emissions.
Today, as the global push for sustainability intensifies, governments, businesses, and consumers demand innovative packaging solutions. Several pathways are emerging to minimize the environmental impact of alcohol packaging, ranging from lightweight glass to biodegradable materials.
Among these, plastic-based refillable bottles stand out as a promising solution. However, their adoption presents unique challenges that require careful navigation.
This article delves deep into the complexities of adopting plastic-based refillable bottles in the alcohol industry. From regulatory pressures to consumer perceptions, we’ll explore the obstacles, opportunities, and strategies shaping the future of sustainable packaging.
The Environmental Toll of Glass Bottles
PPWR aside, there is already a need for an alternative to glass bottles for several reasons.
Producing glass is energy-intensive, primarily due to the high temperatures required to melt raw materials like sand, soda ash, and limestone. The melting process consumes about 60-70% of the total energy used in glass manufacturing. In tests, approximately 6.8 million BTU (British Thermal Units) were required to melt each ton of glass.
To put this into perspective, producing 1 kilogram of container glass in North America consumes an average of 16.6 megajoules (MJ) energy. In comparison, the energy required to produce 1 kilogram of plastic is approximately 3.8 MJ, less than ¼ of glass.
According to a study by The Carbon Trust, transporting glass bottles can result in 40% higher emissions than lightweight alternatives like PET.
That’s why the alcohol industry needs to shift the material from glass to other materials, and plastic-based bottles are one viable alternative.
Why Plastic-Based Refillable Bottles?
Typically made from durable PET plastic, these bottles can be reused multiple times—up to 25 cycles—before being recycled. This reusability significantly reduces the demand for new packaging materials and decreases overall waste.
One primary benefit of refillable plastic bottles is their lower environmental footprint than single-use glass bottles. Studies indicate that refillable PET bottles can reduce greenhouse gas emissions by up to 50% compared to their single-use counterparts.
Additionally, their lighter weight reduces transportation emissions, further contributing to sustainability goals.
Several companies have already demonstrated the potential of plastic-based refillable bottles:
- Garçon Wines: By creating flat wine bottles from 100% recycled PET, Garçon reduced CO2 emissions by 77% per bottle. Their innovative design also optimizes logistics, allowing up to 91% more bottles to fit on a pallet than traditional glass bottles.
“The wine industry is unnecessarily hampered by a bottle that is no longer fit for purpose for the vast majority of wines,” said Santiago Navarro, Garçon Wines. “Ours is a 21st-century bottle.”
- Amcor Rigid Packaging: Amcor developed PET bottles with silicon oxide (SiOx) coatings, which offer glass-like clarity while cutting carbon footprints by 30%. These bottles are fully recyclable and retain a premium aesthetic.
Challenges in Adopting Plastic-Based Refillable Bottles
Despite their potential, plastic-based refillable bottles face several obstacles that the industry must address:
1. Consumer Perception
Recollection: According to experts, the hardest part is “the recollection” – getting bottles back from consumers. Without an effective return loop, reuse falls apart. Many consumers are accustomed to the convenience of disposable packaging and may perceive refillable options as less convenient or hygienic.
Educating consumers on the environmental benefits and safety of refillable bottles is essential. Incentive programs, such as deposit-return schemes, can encourage participation by providing financial rewards for returning used bottles.
Preconceived Notion: Many consumers associate plastic packaging with low quality and environmental harm. These perceptions can hinder adoption, especially in the premium spirits market.
Regional Variations: While U.S. consumers value convenience and lightweight packaging, European consumers prioritize recyclability and aesthetics. To address these regional differences, tailored strategies are required.
2. Recycling Infrastructure
Inconsistent Systems: PET recycling capabilities vary widely worldwide. While Japan achieves an 86% PET bottle recycling rate, many developing countries lack the infrastructure to process large-scale plastic waste.
Recycling Process: The complexity of recycling processes, especially multilayer packaging, poses significant challenges. Many beverage containers, including those used in the alcohol industry, are not designed for easy recycling, leading to low recycling rates and increased landfill waste.
3. Integration with Supply Chains
Storage Issues: Supply chain adjustments are required. Retailers need storage for empties, and brewers need bottle-washing lines. Many wine producers don’t have a local washing plant or collection system, so creating one is a huge undertaking.
Compatibility Issues: Refillable plastic systems must integrate seamlessly into existing manufacturing processes, distribution networks, and retail systems. This transition may require significant investment in supply chain adjustments.
Logistics Issues: Setting up recollection bottles involves reverse logistics (transporting empties), cleaning facilities, and possibly deposit/refund systems. Logistics must be optimized to handle the reverse supply chain efficiently. This includes developing standardized bottle designs to facilitate easy cleaning and refilling and coordinating with retailers to manage the collection process.
4. Cost
The financial feasibility of adopting refillable plastic bottles depends on various factors, including production costs, the bottles’ lifespan, and the return system’s efficiency.
The initial costs of producing durable refillable bottles and creating the necessary infrastructure can be high. Small and medium-sized enterprises (SMEs) might struggle with these investments without external support or incentives.
5. Regulatory Hurdles
Ensuring that refillable bottles meet health and safety standards, especially for alcoholic beverages, adds another layer of complexity. Regulations vary by region and affect material specifications, health and safety standards, and recycling protocols.
Achieving compliance requires a thorough understanding and adaptation to these regulations, which can be resource-intensive. Moreover, the lack of standardized practices across regions can complicate efforts for companies operating in multiple markets.
Strategies to Overcome Challenges
To unlock the potential of plastic-based refillable bottles, the alcohol industry must adopt a multi-faceted approach:
1. Material Innovation
Advanced Coatings
Enhancing the barrier properties of polyethylene terephthalate (PET) bottles is crucial for preserving the quality of premium spirits. One effective method involves applying silicon oxide (SiOx) coatings to the interior surfaces of PET containers. These micro-thin, glass-like layers significantly reduce the permeability of gases such as oxygen and carbon dioxide, thereby extending the shelf life of the beverage.
Research indicates that SiOx coatings can improve the oxygen barrier performance of PET bottles by 37 times, effectively minimizing oxidation and maintaining product integrity.

Mono-Material Designs
Simplifying packaging materials enhances recyclability. Utilizing single-material bottles with easily detachable closures and labels ensures that the entire packaging can be processed uniformly during recycling.
This approach reduces contamination in recycling streams and aligns with circular economy principles by facilitating the complete recovery of materials. For instance, PET bottles designed with PET caps and labels eliminate the need for material separation, streamlining the recycling process.
In addition to PET, polylactic acid (PLA) has also emerged as a viable alternative for creating biodegradable packaging solutions, demonstrating flexibility for applications such as the production of bottle bodies and closures. Incorporating sustainable materials reflects a broader industry trend towards minimizing environmental footprints and adhering to regulatory pressures regarding packaging waste.
Flexible Refill Formats
Innovative refill solutions, such as flexible pouches, offer substantial environmental benefits over traditional glass bottles. Broken Heart Spirits, a New Zealand-based distillery, introduced fully recyclable refill pouches that have been shown to reduce associated CO₂ emissions by more than 95%.
These lightweight pouches decrease transportation emissions and enable businesses to store 166% more stock in the same space as glass bottles.
Additionally, producing these pouches is over ten times cheaper than glass bottles, resulting in a 16.5% cost saving for consumers.
2. Consumer Engagement
Brands must communicate the environmental benefits of refillable plastic bottles to consumers. For instance, Broken Heart Spirits’ “Bottle for Life” initiative educated customers while offering cost-saving incentives.
Deposit-based systems or discounts for returning bottles can drive consumer participation in refillable programs. Deposit return schemes are a proven mechanism to improve recollection, as a high deposit will motivate consumers to bring back bottles.
3. Recycling Infrastructure Development
Collaborations between industry players and governments can facilitate the development of efficient collection and cleaning systems. Pooling resources can mitigate individual costs and promote standardized practices.
For instance, the Oregon Beverage Recycling Cooperative manages a statewide system that benefits multiple distributors through its refillable program.
Using BottleDrop Refillable Bottles, beverage companies gain valuable shelf differentiation through a uniquely eco-friendly packaging solution.
4. Collaborative Efforts
Partnerships between brands, packaging manufacturers, and recycling companies can lead to innovative solutions. Sharing best practices and technologies accelerates the adoption of refillable systems.
The Beer Store in Canada, co-owned by multiple breweries, has successfully implemented a refillable bottle system since 1927 and recovered over 75 billion beer bottles.
5. Standardization
If industry players agree to reuse a few bottle shapes, it simplifies cleaning and sorting. Brewers in the EU have an advantage here as many use the 0.33L or 0.5L Euro-bottle standard for beer. Expanding that concept across more brands and countries helps hit reuse targets faster.
Next Steps
The emergence of material innovations such as SiOx coatings, mono-material designs, refillable pouches, and RFID tracking marks a promising shift in addressing the challenges of refillable bottles in the alcohol industry. These advancements enhance product preservation, recyclability, and efficiency, making refillable solutions more viable under PPWR regulations. However, despite these breakthroughs, significant hurdles remain.
Despite advancements in PET technology, many premium alcohol brands remain hesitant to adopt plastic-based packaging due to concerns about brand image and consumer perception. Glass is still seen as the gold standard for luxury products, and shifting this mindset will require significant effort.
Transitioning to refillable plastic systems often requires substantial upfront investment in new manufacturing equipment, supply chain adjustments, and consumer education. These costs can be prohibitive for smaller brands.
And while regulations push for more sustainable packaging, they often lack clarity or consistency across regions. For example, some countries exclude alcoholic beverages from Deposit Return Schemes (DRS), making it harder for producers to meet sustainability targets.
For refillable bottles to become a mainstream solution, continued innovation, regulatory support, and consumer engagement will be key in bridging the existing gaps.
However, it requires more than just adopting new technologies—it requires a deep understanding of market dynamics, consumer behavior, and regulatory frameworks.
