Choosing the right bioreactor for cultivated meat production boils down to balancing costs, scale, and waste management. Single-use systems are flexible and require less upfront investment, but recurring expenses for disposables can add up. Reusable systems, while expensive initially, are better for long-term, large-scale production due to lower ongoing costs. Here's a quick breakdown:
- Single-Use Bioreactors: Lower initial costs, simpler operations, but generate plastic waste and are limited to smaller volumes (up to 2,000 litres). Ideal for research or small-scale projects.
- Reusable Bioreactors: Higher upfront costs, but better suited for large-scale production with reduced waste. However, they require intensive cleaning and sterilisation, increasing water and energy usage.
Key takeaway: Many producers opt for a hybrid approach - single-use for R&D and reusable for scaling up. Platforms like Cellbase help producers compare options and costs, ensuring informed decisions in this rapidly evolving industry.
1. Single-Use Bioreactors
Single-use bioreactors have become a popular choice in cultivated meat production due to their flexibility and simpler operations. These polymer-based systems bring distinct advantages, particularly in terms of capital and operational costs.
Cost Efficiency
One of the main draws of single-use bioreactors is their lower initial investment. Instead of requiring substantial capital for building new facilities, costs are redirected towards disposable components and growth media [8].
That said, operational costs become a bigger factor as production scales up. For instance, a UK-based techno-economic model estimated that producing cultivated meat using single-use systems could cost £20 per kilogram when using optimised media formulations [1]. While these systems can deliver competitive production costs, the recurring expenses for disposables and media often dominate.
The cost dynamics shift with production scale. For smaller operations, single-use bioreactors are more cost-effective because they reduce upfront investments and simplify facility requirements [1]. But at larger scales, the ongoing expenses tied to disposables and media can outweigh these initial savings. This is particularly relevant in the UK, where energy and waste disposal costs are high [1].
Scalability
Single-use systems shine in speed and flexibility, especially for pilot projects and early commercial efforts [2] [4]. They allow for faster process development and minimise downtime during research and development phases.
Their scalability is particularly beneficial in facilities managing multiple products. These systems eliminate the time-consuming cleaning processes between different cell lines or products, enabling more efficient use of the facility [4].
However, challenges arise at industrial scales. Single-use bioreactors are typically capped at 2,000 litres, making them less suitable for large-scale operations [4] [6]. Managing the logistics of handling vast amounts of disposable materials also becomes increasingly complex as production scales up.
Sustainability
The environmental impact of single-use bioreactors is a mixed bag. On one hand, they generate significant plastic waste due to the disposable nature of their components, including vessels, sensors, and tubing. These solid waste streams must be managed under UK waste regulations [4].
On the other hand, they use far less water and chemicals since no cleaning processes are required [4]. This reduction in liquid waste and chemical use can mitigate some environmental concerns, especially in areas where water treatment and chemical disposal are expensive or sensitive.
Ultimately, the sustainability of single-use systems hinges on local waste management practices and the potential for recycling or energy recovery from used materials [4] [5]. For UK companies, understanding local disposal costs and regulations is essential when assessing the environmental footprint of these systems.
Risk and Reliability
When it comes to reliability, single-use bioreactors offer strong contamination control by providing sterile, pre-validated environments for every production run [4] [6]. This reduces the risk of cross-contamination and ensures consistent batch quality, which is critical for food safety in cultivated meat production.
However, these systems introduce a new set of risks tied to supply chain dependencies. Companies must ensure a steady supply of disposable components, as any delays or quality issues can disrupt production [4]. Material failures, such as bag leaks or ruptures, can result in the loss of an entire batch, highlighting the importance of robust supplier relationships.
To address these challenges, companies often rely on platforms like Cellbase, which connect cultivated meat producers with verified suppliers of single-use systems and consumables. This helps ensure access to high-quality components designed specifically for food production.
Production yields with single-use systems vary widely, ranging from 5–10 g/L to 300–360 g/L, depending on the cell line and process design [8]. This variability underscores the importance of optimising both the bioreactor setup and the cultivation process to achieve cost-effective production.
2. Reusable Bioreactors
Reusable bioreactors are the go-to choice for large-scale cultivated meat production. Stirred-tank reactors, known for their scalability and precise process control, are particularly effective for handling high-throughput operations.
Cost Efficiency
Although reusable bioreactors come with high upfront costs, they make up for it through continuous production cycles that help spread out expenses like energy, cleaning, and water usage over multiple runs[8]. At industrial scales, these systems eliminate the recurring costs associated with disposable components, making them more economical in the long run[8]. However, a significant portion of the ongoing costs stems from energy-intensive sterilisation and water consumption, which are critical for maintaining operational standards under strict regulations[1].
Scalability
When it comes to scaling up, reusable bioreactors are hard to beat. Their sturdy construction allows them to withstand repeated sterilisation cycles while maintaining consistent performance[3][4]. The global market for cultivated meat bioreactors reflects this potential, valued at USD 281.5 million in 2024 and expected to grow at a steady 5.2% CAGR through 2034[9]. Successfully scaling these systems requires meticulous process design to ensure uniform cell growth and efficient use of resources[3]. This durability and scalability make them an integral part of continuous large-scale production.
Sustainability
Reusable bioreactors help cut down on solid waste but come with their own challenges, particularly the intensive cleaning processes. These processes can drive up water and energy costs, especially under the stringent regulations in the UK[1][4].
Risk and Reliability
One of the significant risks with reusable bioreactors is cross-contamination due to insufficient cleaning or sterilisation. Such issues can lead to costly batch losses and downtime for decontamination[1][3]. To minimise these risks, companies must invest in regular maintenance, robust quality control, and validated cleaning protocols. Over time, the mechanical stress from repeated sterilisation cycles can wear down components, requiring eventual replacement. Advanced monitoring systems, priced between £8,000 and £40,000 per vessel, play a crucial role in optimising processes and ensuring quality assurance[10].
For businesses looking to source reliable reusable bioreactor systems and monitoring equipment, platforms like Cellbase provide access to verified suppliers, transparent pricing, and industry-specific expertise tailored to cultivated meat production needs.

Advantages and Disadvantages
When it comes to cultivated meat production, single-use and reusable bioreactors present distinct trade-offs in terms of cost, scalability, environmental impact, and risk management. These differences make it possible to compare the two approaches directly and quantitatively.
Cost efficiency is a balancing act. Single-use bioreactors require less capital upfront since they don't need expensive cleaning and sterilisation infrastructure. But their operating costs can stack up due to the recurring expense of disposable components. On the other hand, reusable systems demand a higher initial investment - installing a 20 m³ stainless steel system, for example, can cost around £1.2 million - but they tend to be more economical for larger-scale operations over time[3].
Scalability also depends on production goals. Reusable bioreactors are ideal for large-scale, continuous production, making them a natural fit for commercial operations. Single-use systems, however, are generally limited to volumes of up to 2,000 litres, which makes them better suited for research, development, or pilot-scale projects. As production scales up, managing numerous disposable units becomes increasingly challenging, tilting the balance in favour of reusable systems[3][4].
Environmental considerations vary significantly between the two. Single-use bioreactors generate a considerable amount of plastic waste, which raises concerns about waste management. Reusable systems, while producing less waste, require substantial amounts of water, energy, and chemicals for cleaning and sterilisation. At industrial scales, however, reusable systems can achieve lower per-unit environmental impact, especially when paired with renewable energy sources and efficient cleaning processes[1][4].
Risk management is another critical factor. Single-use systems minimise the risk of cross-contamination since each vessel is sterile and used only once. This is particularly important for high-value cell cultures, where contamination can lead to costly losses. Reusable bioreactors, however, require rigorous cleaning and sterilisation to prevent contamination, and any failure in these processes can have severe consequences.
| Criteria | Single-Use Bioreactors | Reusable Bioreactors |
|---|---|---|
| Cost Efficiency | Lower initial costs; higher consumable expenses | Higher upfront costs; lower long-term expenses |
| Scalability | Limited to smaller volumes; R&D focus | Suitable for large-scale production |
| Environmental Impact | More plastic waste; less cleaning resource use | Less waste; higher water and energy demands |
| Risk Management | Low contamination risk; simpler validation | Higher contamination risk; complex cleaning |
| Operational Flexibility | Faster changeovers; ideal for diverse projects | Better for long, continuous production runs |
Operational flexibility further differentiates the two. Single-use systems allow for quicker changeovers between production runs, eliminating the need for time-consuming cleaning and sterilisation. This makes them a good choice for facilities managing multiple product lines or research projects. Reusable systems, while less agile due to cleaning requirements, shine in long, continuous production campaigns[1][3].
The cultivated meat industry appears to be leaning towards a hybrid approach. Single-use systems are likely to remain crucial for early-stage development and small-scale production, but as the industry grows, reusable bioreactors are expected to take centre stage due to their cost and operational advantages at scale. Some leading companies have already achieved impressive results, reporting cell densities of 60–90 g/L and production costs as low as £8–12 per kilogram of cell mass[7].
For companies navigating these decisions, platforms like Cellbase simplify the process by providing access to verified suppliers and transparent pricing. This enables producers to select bioreactors tailored to their specific needs, making the complex procurement process more manageable.
Conclusion
Techno-economic assessments reveal that single-use systems are well-suited for early-stage, small-scale production, while reusable systems tend to offer better cost efficiency over the long haul at commercial scales. Precise, context-driven cost modelling is critical for making well-informed procurement choices. These findings echo earlier observations about cost dynamics and risk management, highlighting an industry trend towards adopting a hybrid approach.
Recent advancements - such as achieving cell densities of 60–90 g/L and reducing production costs to as low as £8–12 per kilogram - emphasise the importance of keeping cost models up to date[7]. Models created even 18 months ago may no longer reflect current realities, making it crucial for producers to rely on the latest data and adopt adaptable procurement strategies.
In the UK, regulatory requirements for food safety and traceability add another layer of complexity. Producers must weigh the simplified validation processes of single-use systems against the more sustainable but intricate protocols of reusable systems. These regulatory demands further underscore the importance of flexible procurement strategies.
A hybrid approach - leveraging single-use systems for research and development while transitioning to reusable systems for scaling up - offers a balance between adaptability and long-term economic benefits. Platforms like Cellbase play a vital role in supporting UK cultivated meat producers by providing access to verified supplier data and transparent pricing, enabling more informed decision-making during these strategic transitions.

Your decision should align with your production scale, budget, and sustainability priorities.
What are the environmental differences between single-use and reusable bioreactors, particularly regarding waste and resource consumption?
Single-use bioreactors tend to create more waste because their components are discarded after a single use. That said, they often require fewer resources upfront - like water and energy - since there's no need for cleaning or sterilisation.
In contrast, reusable bioreactors generate less solid waste over time but come with higher ongoing resource demands. They require substantial amounts of water, energy, and cleaning agents to maintain. The overall environmental impact of either option depends on factors such as the production scale, operational efficiency, and how waste is managed. By conducting thorough cost and sustainability analyses, producers can identify the most suitable approach for their cultivated meat production goals.
What are the risks of using single-use bioreactors, and how can these be managed effectively?
Single-use bioreactors provide convenience and adaptability, but they aren't without their challenges. Common concerns include the risk of material failure, such as leaks or tears in disposable components, and the environmental impact of increased plastic waste. On top of that, disruptions in the supply chain can create issues, as these systems depend heavily on a steady supply of disposable materials.
To address these challenges, manufacturers can adopt several strategies. Ensuring rigorous quality control processes helps verify the reliability of disposable components before use. Building strong relationships with suppliers and keeping a reserve stock of critical materials can minimise the risks associated with supply chain disruptions. To tackle environmental concerns, companies could explore recycling initiatives or collaborate with suppliers that focus on using sustainable materials, helping to curb the plastic waste problem.
