Cultivated Meat offers a more resource-efficient alternative to conventional farming, but its packaging must align with its eco-conscious appeal. This article reviews four packaging types that balance product protection and waste reduction:
- Biodegradable Materials: Made from plants, they decompose naturally but often require industrial composting and can be costly.
- Plant-Based Plastics: Renewable and quicker to break down than petroleum plastics but have higher costs and limited oxygen barriers.
- Reusable Designs: Durable options like glass reduce waste but increase transport emissions and require sterilisation.
- High-Barrier Compostable Films: Provide strong protection and compostability but are expensive and need specific disposal conditions.
Key takeaway: High-barrier compostable films combined with Modified Atmosphere Packaging (MAP) currently offer the best balance of product preservation and waste reduction. While costly, they meet the sterility and shelf-life needs of Cultivated Meat while reducing packaging waste. Future innovations, like hybrid systems and active packaging, could further improve efficiency and reduce costs.
1. Biodegradable Materials
Biodegradable packaging, created from renewable plant-based resources, breaks down naturally after disposal. For Cultivated Meat, this type of packaging supports its sustainability goals while still ensuring the product remains well-protected. Examples include compostable protein bags and barrier-coated solid board packaging [7][8][11].
Environmental Impact
Using biodegradable materials reduces dependence on virgin plastics and other non-renewable resources [7]. This is particularly relevant for Cultivated Meat, given that traditional animal farming is responsible for about 57% of agricultural greenhouse gas emissions and uses as much as 83% of available agricultural land [9]. By 2040, cell culture technology is expected to account for up to 35% of global meat production [9]. Sealed Air highlights the role of this packaging:
Biodegradable or compostable food packaging, derived from renewable resources like plant-based materials, contributes to enhancing the sustainable characteristics of packaging [7].
This type of packaging is especially useful in cases where food contamination prevents traditional recycling methods.
Suitability for Cultivated Meat
Biodegradable materials not only offer environmental benefits but also meet the specific protective needs of Cultivated Meat. For instance, barrier-coated solid board packaging shields the product from oxygen, moisture, and contamination, while also reducing condensation that could lead to bacterial growth [11]. This packaging maintains its strength even in the humid, chilled, or frozen conditions necessary for meat storage and transport [11]. To further preserve product quality, brands often combine biodegradable packaging with vacuum-sealing techniques to limit oxidation [7][8]. Additionally, fibre-based boards allow products to freeze faster compared to traditional materials, ensuring better quality during freezing [11].
Cost Implications
Cost remains a significant hurdle. A detailed comparison of plant-based packaging and petroleum-based polymers is still lacking [12], and the transition from lab-scale innovation to commercial production faces financial challenges [12]. To manage higher costs, manufacturers are turning to more efficient, leaner packaging designs [7]. Rick Stein, Vice President, Fresh Foods at FMI, notes:
Sustainability will become a table stake in protein packaging [8].
However, meeting stringent requirements like sterility and effective barrier protection can further increase costs [1][2]. That said, as production scales up and the global meat packaging market grows from £12.5 billion in 2024 to an estimated £18.7 billion by 2033 [10], economies of scale are expected to bring these costs down over time.
2. Plant-Based Plastics
Plant-based plastics, also known as bioplastics, are made from renewable resources like corn, sugarcane, or cassava. Unlike conventional plastics derived from petroleum, which can linger in the environment for centuries, bioplastics break down much faster under microbial action [5][13]. Judith L. Fridovich-Keil, a professor at Emory University School of Medicine, highlights this distinction:
Unlike traditional plastics, which are derived from petroleum, bioplastics are obtained from renewable resources, and some bioplastics are biodegradable [5].
The growing interest in bioplastics stems from the need for sustainable solutions and shifting consumer preferences.
Environmental Impact
Conventional plastics often degrade into microplastics, which accumulate in living organisms and ecosystems. In contrast, many bioplastics decompose into natural by-products [5]. This is particularly important as global plastic production has skyrocketed, increasing from 1.5 million metric tonnes in 1950 to an estimated 359 million metric tonnes by 2018 [5]. Consumers are taking note - 70% of buyers surveyed are willing to pay more for sustainable packaging, and 55% express concerns about the environmental effects of packaging [13]. For Cultivated Meat, which already aims to address environmental issues tied to traditional farming, plant-based packaging strengthens its eco-friendly appeal.
Suitability for Cultivated Meat
Plant-based biopolymers are being developed into active packaging systems specifically designed for Cultivated Meat [12]. These materials help maintain product quality during transportation by incorporating antimicrobial, antioxidant, and antifungal agents, which extend shelf life. This is a crucial feature, as Cultivated Meat is prone to oxidation and microbial contamination [2][3]. Studies back up these benefits: for example, thermoplastic starch films infused with cinnamon or sappan powders preserved meat colour and slowed microbial growth for up to 6 days. Similarly, watermelon peel pectin films with beetroot extract kept chilled beef fresh for up to 8 days [2]. Advanced manufacturing techniques like 3D printing and electrospinning allow these materials to be shaped into various forms, tailored to meet the specific needs of meat alternatives [12].
Cost Implications
One of the biggest hurdles for bioplastics remains their cost. Producing them is still expensive, with lower yields and higher production costs compared to traditional plastics [5]. Currently, plant-based plastics can cost 20–50% more than petroleum-based alternatives [14]. However, there is a silver lining: 75% of millennials are willing to pay extra for sustainable products [13]. Additionally, advancements in production methods and scaling up manufacturing are expected to reduce costs over time. For now, subsidies and deposit schemes are often necessary to make bioplastics competitive, but as demand grows and economies of scale kick in, the price gap should narrow [5].
Shelf-Life Performance
While bioplastics offer clear environmental benefits, their performance in preserving freshness still lags behind traditional packaging. For instance, active plant-based films can keep meat fresh for 6–8 days, whereas conventional Modified Atmosphere Packaging (using PET/EVOH/LDPE layers) can maintain freshness for up to 14 days [2]. Bioplastics also face challenges with high gas and water vapour permeability, which can compromise the protective atmosphere inside the packaging [2]. Another limitation is that many bioplastics require industrial composting under specific conditions, which can complicate their disposal [5].
Despite these challenges, plant-based plastics represent an important step towards more sustainable packaging solutions, especially as technology continues to improve.
3. Reusable Designs
After exploring biodegradable and plant-based packaging, let's turn our attention to reusable solutions. Reusable packaging extends the lifecycle of materials, keeping them in use and significantly reducing waste. This approach is particularly relevant when you consider that over 40% of plastic waste comes from single-use items, often discarded immediately after use [15]. For Cultivated Meat, which is produced under sterile conditions, reusable packaging must strike a balance between environmental advantages and stringent food safety standards.
Environmental Impact
Reusable packaging offers a clear environmental advantage. Every year, more than 2 billion tonnes of waste end up in landfills worldwide, with the food and drink sector responsible for over half of packaging-related pollution [15][16]. By extending the lifespan of materials, reusable packaging reduces the need for new production, saving energy and resources. The Ellen MacArthur Foundation highlights this point:
The circular economy gives us the tools to tackle climate change and biodiversity loss together while addressing important social needs [16].
A great example of this in action is Modern Milkman, a UK-based business that launched its "return and reuse" system in March 2022. Using glass bottles that customers return for sterilisation and reuse, the company has prevented over 68 million plastic bottles from entering the environment. Each bottle can be reused around 30 times before being recycled [16]. This model demonstrates how reusable systems can work effectively for perishable goods, creating a zero-waste loop and significantly cutting a brand's carbon footprint [15].
Suitability for Cultivated Meat
Reusable packaging for Cultivated Meat faces unique challenges due to the product's high perishability. Containers must be sterilised to medical-grade standards between uses and maintain high-barrier properties to prevent oxidation and contamination [2]. Temperature control is also critical, with solutions like wool liners and gel ice packs helping to keep products at fridge temperatures of 4–7°C for up to 48 hours during transit [4]. Wool, a natural byproduct of sheep farming, offers a compostable alternative to polystyrene while providing excellent temperature regulation [4].
The Wild Meat Company has shown how eco-friendly packaging can deliver results, earning a 4.8/5 rating from 545 reviews for its well-insulated, sustainable designs that maintain product quality during delivery [4]. These examples highlight how reusable packaging can meet the needs of perishable foods while aligning with environmental goals.
Cost Implications
The economics of reusable packaging depend largely on infrastructure. While manufacturers save on the cost of producing single-use materials, they must invest in systems for collecting, cleaning, and redistributing reusable containers [16]. For local distribution, these systems often prove cost-effective. However, transporting heavier materials like glass over long distances can diminish some of the environmental benefits.
Though initial investments may be steep, the long-term savings are worth noting. As Packhelp puts it:
Creating multiple uses for packaging increases the lifespan of your packaging by decreasing the likelihood it will end up straight in landfill [15].
For Cultivated Meat producers, competing with the cost of conventional meat remains a challenge. However, as the industry grows and infrastructure improves, reusable systems could become more affordable. Beyond cost, ensuring that packaging maintains product quality through repeated use is a key priority.
Shelf-Life Performance
To extend shelf life, techniques like Modified Atmosphere Packaging (MAP) or vacuum sealing can be integrated into reusable containers [2]. The real challenge lies in ensuring these high-barrier properties endure through multiple use cycles without degradation. This is critical for maintaining the sustainability credentials discussed earlier.
Cultivated Meat's sterility gives it a potential edge in shelf-life over traditional meat, but this advantage only holds if the packaging preserves these conditions during the final stages of delivery [1][2]. Reusable designs must be made from durable materials capable of withstanding industrial sterilisation processes, ensuring that every cycle meets the same rigorous food safety standards as the first use.

4. High-Barrier Compostable Films
High-barrier compostable films offer a blend of strong protective qualities and the ability to break down in composting environments. Unlike simpler materials like plain paper or basic Polylactic Acid (PLA), these films use multi-layer structures to shield products from oxygen, moisture, and light - key factors in preserving highly perishable items like Cultivated Meat.
Environmental Impact
Cultivated Meat production has the potential to cut greenhouse gas emissions by 78%–96% and reduce land use by 99% compared to traditional meat farming [17]. When paired with compostable packaging, the environmental benefits multiply. Instead of lingering in landfills, this packaging enriches the soil as it decomposes. To meet EU standards, such materials must disintegrate within 12 weeks and fully biodegrade within six months [20].
Real-world examples highlight the growing shift toward compostable solutions. In January 2022, Lidl GB replaced traditional soft plastic with compostable bags for fruit and vegetables, cutting about 275 metric tonnes of plastic waste annually [20]. Similarly, PepsiCo's Frito-Lay division introduced compostable bags for its "Off The Eaten Path" brand at Whole Foods Market in September 2021, aligning with its sustainability goals. Consumer surveys consistently show a strong interest in eco-friendly packaging options [19].
Suitability for Cultivated Meat
Beyond its environmental benefits, high-barrier compostable films address the unique needs of Cultivated Meat. Though produced in sterile environments, Cultivated Meat is vulnerable to contamination during packaging and post-processing [2][3]. These films help control oxygen exposure, which is critical for preventing spoilage, lipid oxidation, and off-flavours. They also maintain the stability of heme proteins (if used for colour) [2]. Given the product’s perishable nature, advanced packaging solutions are essential for safe transportation and storage.
Typically combining PLA with PBAT, these films offer the flexibility and durability needed for techniques like Modified Atmosphere Packaging (MAP) or vacuum sealing. Such methods can extend shelf life to 14 days while keeping the packaging fully compostable [2]. For example, China’s PBAT production surged from 150,000 tonnes in 2020 to an estimated 400,000 tonnes by 2022, reflecting the growing demand for such materials [20].
Cost Implications
High-barrier compostable films strike a balance between performance and affordability. As Kate McCauley, Marketing Manager at Law Print Pack, points out:
"For many food products using paper alone cannot preserve the product for the time now expected by many retailers" [18].
To enhance barrier properties, manufacturers often add bioplastic laminations like PLA, which can make these films pricier than basic paper alternatives. However, this extra cost can be offset by reduced food waste. Vacuum packaging with high-barrier films, for instance, can double shelf life to 14 days at 4°C [2]. Rick Stein, Vice President of Fresh Foods at FMI, notes:
"The industry will balance cost and responsibility" [8].
For Cultivated Meat producers, already contending with high production costs, this type of packaging represents an additional expense. However, with 75% of millennials willing to pay more for sustainable products [19], the investment could help brands appeal to environmentally conscious consumers.
Shelf-Life Performance
To compete with conventional plastics, high-barrier compostable films must deliver comparable protection. A key factor is the oxygen transmission rate (OTR) - lower OTR values help prevent oxidation, which can cause off-flavours and discolouration. Multi-layer laminates made from PLA and PBAT achieve the low permeability needed to keep products fresh throughout the supply chain [21].
Emerging technologies are pushing the boundaries of shelf-life performance even further. Active packaging, for example, incorporates natural antioxidants like green tea extract or oregano essential oil to combat microbial growth and lipid oxidation, extending shelf life by an additional 2–4 days [2]. Shahida Anusha Siddiqui, a researcher at LWT Journal, explains:
"The sterility of the cultured meat promotes its use as safe meat with long shelf life and reduces food loss" [2].
However, ensuring these films maintain their high-barrier properties while also breaking down in composting facilities presents a challenge. Brands must clearly label whether the films require industrial composting or are suitable for home composting, as proper degradation often depends on specific conditions [21][18].
This packaging innovation is a vital part of the broader sustainability strategy for Cultivated Meat, combining effective protection with eco-conscious design to meet the demands of both producers and consumers.
Advantages and Disadvantages
Eco-Friendly Packaging Options for Cultivated Meat: Comparison of Environmental Impact, Cost and Suitability
This section outlines the main trade-offs for each packaging option discussed earlier, focusing on how they balance protecting Cultivated Meat and reducing environmental impact.
Biodegradable materials break down naturally, which helps reduce landfill waste. However, their decomposition often relies on industrial composting facilities, and in some cases, they can degrade into microplastics. On the plus side, they are typically free from harmful chemicals like phthalates, and active additives can enhance shelf life.
Plant-based plastics, such as PLA, are made from renewable sources and use 52% less non-renewable energy during production compared to petroleum-based plastics. They can biodegrade within six months in industrial composting facilities [22]. However, they are more expensive than traditional plastics and sensitive to heat - temperatures above 35°C can weaken them. Additionally, PLA alone may not provide sufficient oxygen barriers to prevent colour loss in Cultivated Meat [2][22].
Reusable designs, especially glass containers, offer a low environmental impact over time if reused consistently. However, their weight increases transport emissions, and they require thorough sterilisation. While reusable packaging aligns with the sustainability values of UK consumers, the upfront costs and logistical challenges can be significant [6].
High-barrier compostable films are specifically designed for perishable goods. Their multi-layer structure helps prevent oxidation and preserves the meat's colour, extending shelf life to about 14 days when used with Modified Atmosphere Packaging. However, this is the most expensive option available [2][21].
Here’s a quick comparison of these packaging options in terms of environmental impact, cost, and suitability for Cultivated Meat:
| Packaging Type | Environmental Impact | Cost | Use for Cultivated Meat |
