When choosing a bioreactor for cultivated meat production, single-use systems and reusable systems each offer distinct cost advantages and challenges. Here's the key takeaway:
- Single-Use Bioreactors: Lower upfront costs (50–66% less than reusable systems), reduced labour, and no cleaning requirements. Ideal for startups, small-scale production, or facilities needing flexibility. However, they have higher consumable costs (e.g., ~£6.4M annually at 2,000-litre scale) and generate plastic waste.
- Reusable Bioreactors: Higher initial investment but lower long-term costs for large-scale, stable production. Cleaning and validation increase running costs, but reusable systems become more cost-efficient after ~30 batches. Best for high-volume operations exceeding 8,000 litres or consistent production schedules.

Your decision depends on production scale, cost priorities, and operational needs. Single-use systems suit agility and lower upfront costs, while reusable systems excel in long-term savings for high-volume setups.
Cost Structure Breakdown
Let’s dive into three key cost categories: upfront investment, running costs, and labour/validation expenses. Each plays a unique role in shaping the overall cost of ownership, depending on whether you choose single-use or reusable systems. These factors form the foundation for a thorough cost comparison.
Upfront Investment Costs
The initial capital outlay is one of the most striking differences between single-use and reusable bioreactor systems. Single-use bioreactors require less upfront spending because they eliminate the need for complex infrastructure. On the other hand, reusable stainless steel systems demand significant facility upgrades, including clean-in-place (CIP) and steam-in-place (SIP) systems, additional utilities for steam generation, and advanced waste management setups. These requirements push capital costs much higher.
For perspective, single-use skids typically cost about 50–66% less than stainless steel systems [4]. This makes them an attractive choice for startups or smaller-scale operations with limited budgets. For a 2,000-litre production setup, facility-related costs for single-use systems amount to roughly £21.5 million annually, compared to around £30.3 million for their stainless steel counterparts [9]. That’s a substantial difference of £8.8 million, which can significantly influence cash flow and return on investment (ROI). While single-use systems are ideal for emerging businesses, the infrastructure investment in reusable systems often pays off for high-volume production facilities.
Running Costs
Operating expenses also vary between the two systems. Reusable systems come with ongoing costs for cleaning and maintenance - expenses that single-use systems avoid entirely. For instance, cleaning reusable systems can consume up to 4,900 MJ of energy per batch [2], whereas single-use components eliminate this energy use.
However, single-use systems aren’t without their own recurring costs. Consumables, such as disposable bags, represent a significant portion of operating expenses. A 1,000-litre single-use bag costs around £4,000–£5,000, while a 500-litre buffer storage bag is priced at £400–£500 [6]. At a 2,000-litre scale, consumable costs for single-use systems can total £6.4 million annually, compared to approximately £4.0 million for stainless steel systems [9]. This £2.4 million difference highlights how consumable expenses can partially offset the savings from lower infrastructure costs, especially in high-frequency production scenarios.
Labour and Validation Costs
Labour demands also differ significantly between the two systems. Reusable bioreactors require more skilled labour for cleaning, sterilisation, and validation processes, all of which are critical for meeting regulatory standards. This labour-intensive process also leads to longer downtimes between production cycles.
Single-use systems, by contrast, cut labour requirements by 30–50% by eliminating the need for extensive cleaning and validation [5]. Validation costs for reusable systems can range from £40,000 to £120,000, depending on system complexity and regulatory demands, whereas single-use systems typically incur validation costs of under £8,000 [5]. Faster changeovers with single-use systems further enhance production efficiency, reducing downtime and lowering the cost per batch.
| Cost Category | Single‑Use Systems | Reusable (Stainless Steel) Systems |
|---|---|---|
| Upfront Investment | 50–66% lower than reusable | Higher due to CIP/SIP and facility upgrades |
| Annual Consumables | ~£6.4 M (2,000‑L scale) | ~£4.0 M (2,000‑L scale) |
| Facility Costs | ~£21.5 M annually | ~£30.3 M annually |
| Validation | Under £8,000 | £40,000–£120,000 |
| Labour Reduction | 30–50% lower | Higher due to cleaning and validation |
These cost dynamics create distinct economic profiles. Single-use systems provide savings upfront due to lower capital requirements, making them appealing for smaller-scale operations. On the other hand, reusable systems often deliver lower per-batch costs in large-scale production settings. For cultivated meat producers, aligning their bioreactor choice with financial goals and production needs is critical to optimising overall costs.
Single-Use Bioreactors: Cost Analysis
Cost Benefits
For cultivated meat producers, single-use bioreactors present clear financial advantages. Beyond saving on initial capital, these systems significantly cut operational costs by removing the need for costly infrastructure like clean-in-place (CIP) and steam-in-place (SIP) systems, intricate piping networks, and extensive facility upgrades.
One major cost saver is the elimination of cleaning and validation processes. Traditional reusable systems consume over six times more energy for sterilisation between batches compared to single-use bioreactors. Since single-use systems come pre-sterilised and are disposed of after use, they reduce labour needs by an estimated 30–50% [2][5]. Additionally, skipping lengthy cleaning cycles allows for faster changeovers, a crucial benefit in an industry where product development moves quickly, and market demands can shift unexpectedly.
However, while these savings are impressive, they must be weighed against the ongoing costs of consumables, which are explored next.
Cost Drawbacks
Although single-use bioreactors save on upfront costs, the recurring expenses of consumables can add up fast. For example, a 1,000-litre single-use bioreactor bag costs about £3,800, while a 500-litre buffer storage bag is priced at roughly £380 [6]. At a production scale of 500 kg/year, material costs for single-use systems can be up to 1.8 times higher than those for batch bioreactors [3]. Some studies suggest that reusable systems become more cost-efficient after around 30 batches [4].
Another challenge is the significant plastic waste generated by single-use systems. Items like bags, filters, tubing, and connectors - primarily made from polypropylene - can lead to increased disposal and compliance costs, especially as regulations around plastic waste become stricter in the UK and Europe [2][8].
When to Choose Single-Use
The choice to use single-use bioreactors depends heavily on the specific production needs and priorities. As previously discussed, these systems shine in scenarios where production agility and contamination risk control are key.
Single-use bioreactors are particularly cost-effective for small-scale production, typically below 2,000–8,000 litres. In these cases, the savings on facility costs often outweigh the higher consumable expenses [9]. This makes them ideal for R&D, pilot-scale production, and product development, where flexibility is critical.
For companies producing a variety of cultivated meat products, single-use systems minimise cross-contamination risks and eliminate the need for cleaning validation. This is especially beneficial for operations working with distinct cell lines or growth conditions, enabling them to maintain a diverse product portfolio without added complexity.
Frequent process adjustments, such as testing new cell lines or fine-tuning growth media, are also easier to manage with single-use systems due to their quick turnaround times. This flexibility is a major advantage for early-stage companies, where production schedules are often unpredictable, and batch sizes vary.
Start-ups, in particular, benefit from the lower initial investment required for single-use bioreactors. The reduced capital costs allow these companies to begin production sooner, conserve funds for essential activities like product development and market entry, and operate with smaller teams who may lack extensive expertise in cleaning and validation protocols.
| Production Scenario | Single-Use Suitability | Key Cost Advantage |
|---|---|---|
| R&D and pilot-scale | Excellent | Lower facility costs and rapid changeovers |
| Multi-product facilities | Excellent | Avoids cross-contamination risks |
| Small batches (<2,000L) | Very good | Facility savings offset consumable costs |
| Irregular production | Very good | Savings from eliminating cleaning costs |
| Start-up operations | Excellent | Minimal upfront capital required |
Ultimately, the decision comes down to balancing short-term capital needs with long-term operational expenses. Single-use systems are most valuable when flexibility, speed, and lower initial investment take precedence over optimising per-batch costs.
Reusable Bioreactors: Cost Analysis
Cost Benefits
After examining both upfront and operational costs, it’s now time to dive into the economics of reusable bioreactors. These systems stand out for their long-term financial advantages, particularly for cultivated meat producers working at scale.
One of the main advantages of reusable bioreactors is the significant reduction in consumable costs over their lifespan. In contrast to single-use systems, which require new components for each production batch, stainless steel reusable bioreactors are built to last for approximately 600 production batches before needing replacement[2]. This durability and the absence of disposable components drive down per-batch costs as production scales up.
However, these benefits come with some notable financial challenges.
Cost Drawbacks
The biggest hurdle with reusable bioreactors is their high initial cost. Compared to single-use systems, they require a much larger capital investment upfront. This includes the cost of cleaning-in-place (CIP) and sterilisation-in-place (SIP) systems, as well as the additional infrastructure required to support them[2][7].
Operational costs also remain a concern. Cleaning reusable systems is resource-intensive, adding 20–30% to overall operational expenses. These processes require substantial energy, large volumes of pyrogen-free water, cleaning chemicals, and the disposal of wastewater. On top of that, additional labour is needed for cleaning validation, ongoing maintenance, and regulatory compliance, further increasing costs compared to single-use alternatives.
While reusable systems offer long-term savings, managing these high initial and operational expenses is essential for their effective use.
When to Choose Reusable
Despite the steep upfront costs, reusable bioreactors are a smart choice for stable, high-volume production. They shine in scenarios where operations are standardised, high-capacity, and predictable. Facilities running 30 or more production batches annually often see significant long-term savings, making reusable systems ideal for established companies with consistent demand.
For large-scale commercial production - typically over 8,000 litres - reusable bioreactors deliver the greatest value. The higher fixed costs are spread across a larger output, reducing the payback period. Additionally, in long production campaigns where the same cell line and growth conditions are used across consecutive batches, reusable systems reduce cleaning frequency and maximise equipment usage.
| Production Scenario | Reusable Suitability | Key Cost Advantage |
|---|---|---|
| Commercial scale (>8,000L) | Excellent | Infrastructure costs offset by high output |
| High-frequency production (30+ batches/year) | Excellent | Faster recovery of initial investment |
| Single product focus | Very good | Simplifies cleaning and lowers associated costs |
| Long production campaigns | Very good | Maximises equipment efficiency |
| Established operations | Good | Predictable demand supports initial investment |
For companies with a strong market presence and steady revenue streams, the upfront cost of reusable bioreactors is often outweighed by long-term savings and a solid return on investment. They’re particularly well-suited to operations that prioritise efficiency and scalability.

Beyond Cost: Other Key Factors
When deciding between single-use and reusable bioreactors for cultivated meat production, cost is just one piece of the puzzle. Other crucial considerations, such as environmental impact, operational efficiency, and regulatory requirements, play a significant role in shaping the decision.
Environmental Impact
The environmental impact of bioreactor systems is a balancing act between waste production and resource usage. Single-use bioreactors, being disposable, generate significant plastic waste, which often ends up in landfills and poses recycling challenges. However, a 2014 study found that at the 2,000-litre scale, single-use systems had a smaller environmental footprint than reusable stainless steel systems across 18 categories, including human toxicity, water depletion, and fossil resource consumption [2]. The main reason? The resource-heavy cleaning and sterilisation processes required for reusable systems.
Reusable bioreactors demand large amounts of pyrogen-free water, cleaning chemicals, and energy for their cleaning-in-place (CIP) and sterilisation-in-place (SIP) processes. These activities consume far more energy per batch compared to single-use alternatives, which bypass cleaning entirely. Additionally, producing the necessary volumes of pyrogen-free water adds to the environmental toll. This interplay between environmental impact and operational processes is closely tied to efficiency, as explored below.
Operational Efficiency
Single-use systems excel in operational efficiency, offering quick setup times and reducing the risk of cross-contamination. Arriving pre-sterilised and ready to go, these bioreactors cut down on preparation time and eliminate lengthy cleaning cycles. This allows for faster batch turnarounds and more flexible scheduling.
On the other hand, reusable bioreactors require comprehensive cleaning and sterilisation protocols. Any misstep in these processes could lead to costly errors, such as batch losses or even product recalls.
Single-use systems also shine in terms of flexibility. They are available in various sizes and configurations, making them well-suited for rapid product development and scaling. In contrast, reusable systems rely on fixed infrastructure, which limits adaptability.
| Operational Factor | Single-Use Systems | Reusable Systems |
|---|---|---|
| Setup Time | Minimal – pre-sterilised and ready | Extended – requires cleaning/sterilisation |
| Contamination Risk | Very low – fresh components each batch | Higher – depends on cleaning validation |
| Batch Turnaround | Rapid – immediate changeover possible | Slower – cleaning cycles required |
| Flexibility | High – easy customisation and scaling | Limited – fixed infrastructure |
Regulatory Requirements
Efficiency aside, regulatory compliance is another critical factor influencing bioreactor selection. In the UK, regulatory bodies like the Medicines and Healthcare products Regulatory Agency (MHRA) and Food Standards Agency (FSA) impose varying requirements depending on the system [2].
For single-use bioreactors, the focus is on ensuring component quality, including sterility and material compatibility. Since cleaning processes are eliminated, validation requirements are simplified, potentially speeding up regulatory approvals and reducing the paperwork burden.
In contrast, reusable bioreactors face more stringent regulatory demands. They must demonstrate effective cleaning and sterilisation through detailed validation studies, extensive documentation, and ongoing compliance checks. This includes proving that all residues are removed and cross-contamination risks are mitigated.
Both bioreactor types must adhere to Good Manufacturing Practice (GMP) standards, though the emphasis differs. For cultivated meat producers, understanding these regulatory nuances is essential to align production workflows with approval timelines and resource planning.

Key Takeaways
Deciding between single-use and reusable bioreactors ultimately comes down to your production scale, operational goals, and financial strategy. Each type has distinct benefits tailored to different business needs, though these choices also come with trade-offs in terms of cost, environmental impact, and operations.
Single-use bioreactors are particularly appealing for research and development (R&D) facilities, pilot-scale setups, or businesses that frequently switch products. They offer lower upfront costs and greater flexibility. For example, at a 2,000-litre production scale, single-use systems show a 24% cost advantage per unit (£317/g compared to £415/g for stainless steel systems) [1][9]. They also eliminate the need for cleaning and sterilisation, which not only reduces energy use but also lowers the risk of contamination. This makes them ideal for facilities producing multiple cultivated meat products or those still in the experimental phase.
However, single-use systems come with higher consumables costs over time. For instance, annual expenses for mixer bags can reach £1.6 million for 40 batches per year [6]. Additionally, at an annual production of 500 kg, material costs for single-use systems are 1.8 times higher than those of reusable systems [3].
On the other hand, reusable bioreactors are better suited for large-scale and stable production operations. While they require higher initial investment, they offer substantial long-term savings. For high-volume producers, the cost advantage of single-use systems diminishes at scales of 8,000 litres or more, where costs per unit for both systems become nearly identical [9]. For businesses with consistent production schedules, reusable systems provide a more economical choice in the long run.
Environmental considerations also play a role. Single-use systems consume less energy overall, as sterilising reusable bioreactors between batches requires over six times more energy than using pre-sterilised single-use components [2]. However, single-use systems generate significantly more plastic waste, creating a balance between energy efficiency and waste management concerns.
