Biodegradable Packaging: How It Works and What to Consider
What is Biodegradable Packaging?
Biodegradable packaging is crafted from materials that microorganisms can break down into water, carbon dioxide, and biomass [5]. Unlike traditional plastics, which can linger in the environment for hundreds of years, these materials decompose naturally through biological processes.
Today, there’s a wide variety of biodegradable materials available. Starch-based bioplastics are commonly used in food packaging, while cellulose films are valued for their effective barrier properties. Other innovative options include mushroom-based packaging grown from agricultural waste, seaweed-derived films, and bagasse, a material made from sugarcane pulp [3][2].
Two materials particularly suited for cultivated meat packaging are PLA (polylactic acid) and PHA (polyhydroxyalkanoates). PLA is known for its clarity and strength, making it ideal for display packaging. On the other hand, PHA offers greater flexibility and can degrade in diverse environments, including industrial composting facilities and marine settings [2].
The time it takes for these materials to decompose varies significantly depending on the type of material and the conditions. For instance, paper packaging can break down in 2–6 weeks, while uncoated cellulose film decomposes in 28–60 days [3]. However, some materials need specific conditions to biodegrade effectively. PLA, for example, requires industrial composting facilities - where temperatures exceed 60°C - to decompose within 3–6 months. Without these conditions, it can persist in natural environments for 80–100 years [4].
These factors highlight both the potential and the complexity of biodegradable packaging, especially when applied to cultivated meat products.
Advantages of Biodegradable Packaging
When it comes to cultivated meat, biodegradable packaging offers benefits that go beyond its eco-friendly appeal. Features like tailored barrier properties, antimicrobial additives, and active packaging technology can transform how meat is packaged, transported, and consumed [6].
The demand for biodegradable packaging is growing rapidly. Back in 2019, the market was valued at approximately £3.6 billion, and it’s expected to soar to around £9.3 billion by 2025, with a compound annual growth rate of 17.04% [3]. This growth reflects increasing consumer interest and regulatory shifts favouring sustainable packaging solutions.
For cultivated meat, bioplastics like PLA and cellulose-based films play a critical role in protecting products from oxygen and moisture, which are key to maintaining freshness during distribution [7]. Active packaging, which incorporates antimicrobial or antioxidant properties, can further enhance food safety and extend shelf life. A study in 2025 demonstrated that biodegradable poly(ε-caprolactone) films infused with antioxidants from pineapple by-products extended the freshness of burger meat by over 10% [8].
Another encouraging trend is the expansion of production capacity for biodegradable materials. Between 2023 and 2028, global production is expected to reach 4.61 million tonnes, helping to address concerns about availability and consistency [6].
Drawbacks of Biodegradable Packaging
Despite its advantages, biodegradable packaging comes with its own set of challenges. One major issue is the reliance on industrial composting facilities, which are not widely accessible across Britain. Without proper infrastructure, materials like PLA may not break down as intended, potentially adding to environmental problems [6].
The UK’s composting network is still uneven, leaving many consumers without access to facilities that can process materials like PLA or bagasse under the required conditions of temperature and humidity [2]. This limited infrastructure can hinder the effective disposal of biodegradable packaging.
Another challenge lies in the mechanical properties of these materials. Pure biopolymers often have weaker performance compared to traditional plastics, and chemical additives are sometimes used to enhance their functionality. However, these additives can undermine the environmental benefits of the packaging [7]. Additionally, more research is needed to refine these materials for specific applications, such as meat packaging.
For cultivated meat producers, these challenges can complicate production. Fresh meat, with its high water activity (above 0.95), is particularly prone to microbial growth and spoilage, demanding high barrier properties from its packaging [6]. Meeting these stringent requirements often makes biodegradable options more expensive than conventional alternatives.
Lastly, inconsistencies in decomposition times can create confusion for consumers. For example, hemp and fibre-based packaging may take 6–9 months to biodegrade under standard conditions, while mushroom packaging can break down in 30–90 days under ideal composting conditions [3]. This variability complicates disposal practices and raises questions about the practicality of biodegradable packaging in the cultivated meat industry.
Recyclable Packaging: How It Works and What to Consider
What is Recyclable Packaging?
Recyclable packaging is made to be collected, processed, and turned into new materials through established recycling systems. Unlike biodegradable options that naturally decompose, recyclable materials retain their structure and can be reused multiple times to create fresh packaging products.
Some of the most common materials used in food packaging include PET (polyethylene terephthalate), HDPE (high-density polyethylene), and recyclable paperboard. PET stands out for its high tensile strength, resistance to chemicals, and ability to remain stable across a wide range of temperatures, making it a great choice for cultivated meat packaging[9]. Meanwhile, HDPE offers excellent barrier properties and is stronger in terms of tensile and bursting resistance when compared to other plastics[9].
The recycling process involves several steps: materials are collected from recycling bins, sorted at Material Recovery Facilities (using optical sorting technology), and then reprocessed through washing, grinding, and converting back into usable materials[11][12]. In the UK, cardboard recycling is particularly effective, with over 70% of cardboard being recycled[12]. These systems provide a reliable framework for sustainable packaging in the cultivated meat industry.
Advantages of Recyclable Packaging
Recyclable packaging supports a circular economy where materials are reused instead of being discarded after a single use. This reduces waste, limits the need for new raw materials, and helps conserve natural resources[14]. For cultivated meat producers, this approach aligns with goals of ensuring product safety while also being environmentally conscious.
The UK has a well-established infrastructure for recycling. Unlike biodegradable packaging, which often needs specialised composting facilities, recyclable materials fit seamlessly into existing collection and processing systems. For example, more corrugated packaging is recovered for recycling than any other type of packaging material, and packaging waste recycling rates in the UK currently stand at approximately 53.9%[13][17].
Consumer preferences also strongly back recyclable packaging. According to a Bain & Company study, 50% of consumers now place sustainability among their top four purchasing considerations[14]. This growing demand means that cultivated meat brands using recyclable options can not only reduce their environmental footprint but also build a stronger, more eco-conscious brand image[16]. Additionally, recyclable plastics like PET and HDPE help cut down on landfill waste and greenhouse gas emissions compared to traditional plastics[15].
PET’s transparency enhances product display, while HDPE’s resistance to chemicals ensures safe storage and transport. Together, they offer flexibility and functionality for packaging strategies.
Drawbacks of Recyclable Packaging
Despite its benefits, recyclable packaging comes with challenges - particularly when used for cultivated meat products. One major issue is contamination from leftover food, which can disrupt the recycling process. Thorough cleaning is often needed before disposal. Adding to the complexity, different types of plastics require separate processing streams[11].
In 2005, packaging materials made up around 31% of municipal solid waste, with food packaging accounting for nearly two-thirds of that total by volume[10]. This illustrates the scale of the waste issue that cultivated meat producers must address.
While recycling systems are more advanced than composting facilities, they still face capacity limitations. Clear labelling and consumer education are essential to improve recycling rates, but many people remain unsure about how to properly dispose of packaging materials[11].
On top of these challenges, cultivated meat producers must navigate strict regulations. In the UK, all packaging materials must comply with food contact rules set by the Food Standards Agency. This means safety assessments are required before any material can be approved for use with food products.
Biodegradable vs Recyclable Packaging for Cultivated Meat
Impact Comparison
Did you know that more than half of the greenhouse gas emissions from packaging come from food waste? This highlights that the real environmental challenge isn’t just the packaging material itself - it’s how well it preserves the product. Interestingly, biodegradable packaging can actually backfire if it leads to higher food waste [18].
Compostable materials generally have a smaller carbon footprint compared to plastics made from petroleum, and they use 65% less energy during production [9]. But here’s the catch: these benefits only come into play when food waste is minimised. For instance, PHA-TPS packaging only achieves lower emissions when it either reduces food waste or aids in composting processes [18].
For brands marketing Cultivated Meat as a greener alternative to conventional meat, this adds a layer of complexity. The choice of packaging isn’t just about the material’s sustainability - it’s about how well it aligns with the product’s overall environmental goals. And this brings up some practical challenges.
Practical Differences
Packaging for Cultivated Meat isn’t just about being eco-friendly; it also has to perform. Biodegradable packaging, for example, needs specific conditions to avoid breaking down too early, while recyclable materials tend to be more stable [19]. Given the refrigeration and shelf-life demands of Cultivated Meat, recyclable packaging often has the upper hand in terms of reliability.
Take multi-layered packaging as an example. It’s typically made of 75% paperboard, 20% plastic, and 5% aluminium, and it does a great job of extending shelf life. But it’s notoriously hard to recycle [19]. On the other hand, biodegradable options rely on consumers having access to composting facilities (and knowing how to use them), whereas recyclable packaging benefits from the UK’s well-established recycling systems. Composting facilities, unfortunately, are still limited in many areas.
Then there’s the design factor. Features like resealable closures, easy-to-open designs, ergonomic grips, and clear safety indicators aren’t just conveniences - they help cut down on waste. For example, oversized or hard-to-empty packaging often leads to food being thrown away unnecessarily [19].
Cost and Scale Considerations
Now let’s talk money. Packaging decisions aren’t made in a vacuum - they’re heavily influenced by costs, especially in an industry where Cultivated Meat already faces steep price challenges. Producing it on a large scale costs around £50 per kg, compared to just £2.20–£2.75 per kg for conventional chicken [21]. With such a big price gap, every expense, including packaging, has to be carefully balanced between sustainability and affordability.
The biodegradable packaging market is growing fast - it was worth about £3.7 billion in 2019 and is projected to hit nearly £9.6 billion by 2025, growing at an annual rate of 17.04% [9]. This growth could make sustainable packaging more accessible and affordable over time.
But it’s not just about material costs. Scaling up Cultivated Meat production requires significant investment. Neta Lavon, Chief Technology Officer at Aleph Farms, explains:
"To expand the technology [required to produce cultivated meat], we need investments in capex [capital expenditure], which are very expensive for this type of tech. Governments should take part [in fundraising], as currently it is mostly led by private investors." [22]
Jung Han, Senior Director of Food Science at Eat Just and Good Meat, also stresses the importance of thinking like a consumer brand:
"When producing cultivated meat products, the most important thing is to have a CPG [consumer packaged goods] mindset." [22]
In short, packaging for Cultivated Meat has to strike a delicate balance. It needs to align with the product’s eco-friendly image, meet practical retail and distribution needs, and fit within tight cost constraints. Transitioning from pharmaceutical-grade to more affordable food-grade nutrients could help lower costs [20]. Ultimately, the right packaging choices will play a key role in helping the industry move from niche production to mainstream success, all while keeping sustainability at the forefront.

New Technologies
The global meat packaging market is poised for substantial growth, expected to rise from US$16 billion (around £13 billion) in 2024 to nearly US$24 billion (approximately £19.5 billion) by 2033 [23]. This growth is being driven by cutting-edge technologies that are redefining how Cultivated Meat is delivered to consumers in the UK. Smart packaging, for instance, now includes QR codes that provide traceability, allowing consumers to access detailed product information with a simple scan. Meanwhile, moulded fibre MAP trays are reducing plastic usage by up to 85%, and APET containers are slashing costs by 70%.
Other innovations include biodegradable films and materials derived from algae and mushrooms, offering eco-friendly alternatives to traditional plastics. Mono-material packaging designs are also simplifying the recycling process, making it easier for consumers to dispose of packaging responsibly. These advancements don’t just protect the product - they transform packaging into an interactive, sustainable tool that aligns with modern consumer values [23][25]. Hybrid materials are also gaining traction, striking a balance between sustainability and functionality [24].
Regulatory and Consumer Changes
In the UK, regulatory frameworks are adapting to accommodate the rise of Cultivated Meat. The Food Standards Agency (FSA) has been working on new regulations, focusing on the term "cellular products" rather than calling it "meat." This distinction has implications for packaging, particularly in terms of labelling and consumer information.
Scarlett Swain, a lecturer in law at Northeastern University, explains: "It is interesting reading through the Food Standards Agency's regulation - they're very much focused on calling it 'cellular products.' They don't use the word meat because they make it very clear that, at the moment, this wouldn't pass under the definition we have legally of meat." [1]
These regulatory updates not only shape labelling practices but also encourage the use of sustainable packaging solutions. Consumer preferences are shifting too, with 82% of people willing to pay extra for packaging that is environmentally friendly [25]. UK supermarkets are responding by setting ambitious goals, such as halving plastic usage or ensuring that all own-label packaging is recyclable, reusable, or compostable at home [26]. The pandemic further accelerated these trends, with Asda reporting a 32% increase in vegan product sales and Waitrose noting a 30% rise in vegan purchases [26].
Role of Educational Platforms
As both regulations and consumer expectations evolve, the need for clear, accessible information becomes more critical. Educational platforms play a key role in bridging this gap. Polling data reveals that between 16% and 41% of the UK population is open to trying Cultivated Meat [1].
Platforms like Cultivated Meat Shop are stepping in to educate consumers not only about the product itself but also about its packaging and sustainability benefits [27]. With Boston Consulting Group projecting that Cultivated Meat could capture 6% of the global alternative protein market by 2035, and 80% of consumers in the US and UK expressing some interest in trying it [28][29], these platforms are essential. By connecting the dots between sustainable packaging and the environmental advantages of Cultivated Meat, they empower consumers to make informed choices. Ultimately, the success of Cultivated Meat packaging will depend on collaboration across the supply chain, with informed consumers driving the demand for both the product and its eco-conscious packaging [28].
Conclusion: Making the Right Packaging Choice
Selecting the ideal packaging for Cultivated Meat goes beyond simply protecting the product or extending its shelf life. It’s about striking a balance between functionality and reducing environmental impact, especially when deciding between biodegradable and recyclable options.
Consumer preferences play a significant role here. Research shows that 84% of consumers consider sustainability when making purchases, and 81% show a preference for eco-friendly packaging. However, confusion over disposal remains a challenge - 42% of consumers, unsure about packaging labels, resort to guessing how to dispose of them [32]. This underlines the importance of clear labelling and consumer education to bridge the gap between intention and action.
Cost is another factor. Sustainable packaging can cost around 25% more than conventional options [30]. Yet, with the compostable packaging market forecasted to double between 2023 and 2031, and 82% of consumers willing to pay extra for compostable solutions [30], this added expense seems increasingly justifiable. Clear labelling also plays a key role in reducing consumer hesitation [48,50]. The most effective strategy combines sustainability with functionality, ensuring freshness and shelf life, while providing straightforward disposal instructions [31].
Whether opting for biodegradable materials that naturally decompose or recyclable ones that can be reused, the packaging must align with the product's specific requirements. Equally important is educating consumers on proper disposal methods, ensuring the sustainability message is clear and actionable.
As the Cultivated Meat industry moves closer to commercialisation, packaging decisions will leave a lasting impression on consumers. Platforms like Cultivated Meat Shop can play a vital role in educating buyers about the environmental benefits and disposal processes of packaging, reinforcing the thoughtful approach behind these products.
