Across life sciences, pharmaceuticals, and healthcare, the pressure to modernize sterilization processes is accelerating. Research teams are challenged by the rising regulatory restrictions on EtO, growing sustainability requirements, and the need for faster turnaround times. These factors together are driving strong interest in supercritical CO₂ (scCO₂) sterilization.

In our Green Initiatives article, we discussed how scCO₂ combines environmental responsibility, operational efficiency, and regulatory awareness, making it an attractive choice for labs preparing for the next decade of innovation.

Why Labs Are Exploring Supercritical CO₂

From specialized academic labs to corporate R&D teams, interest in supercritical CO₂ sterilization is growing rapidly. What drives this momentum is the technology’s ability to directly address three of the biggest challenges in sterilization today: safety, environmental impact, and operational speed.

While NovaGenesis itself is designed for research and development use, the same core technology also underpins larger systems that are being used in commercial manufacturing applications. For research teams, this makes scCO₂ an invaluable platform for testing, optimization, and preparing for a future beyond ethylene oxide (EtO).

1. Regulatory Confidence for Research Environments

NovaGenesis scCO₂ technology is designed to support research and development workflows, providing a controlled, vessel that enables labs to explore innovative sterilization approaches without regulatory bottlenecks.

·         Vessel ensures baseline safety compliance for R&D use.

·         Accelerates compliance-readiness by generating reproducible data that can inform future validation pathways.

·         Facilitates audit preparation through standardized, exportable process documentation suitable for research records.

·         De-risks long-term strategy by allowing teams to explore sustainable alternatives to ethylene oxide (EtO), as regulations tighten and validated sterilization methods evolve.

2. Faster Cycle Times and Operational Throughput

Ethylene oxide (EtO) sterilization often requires 10–12 hours of post-process aeration before items can be safely handled. In contrast, supercritical CO₂ (scCO₂) significantly reduces turnaround times.

·         Same-day workflows – researchers can sterilize and reuse equipment within hours, accelerating project timelines.

·         Improved lab efficiency – reduces backlog in R&D workflows and increases equipment availability.

·         Lower energy use – eliminates long aeration hold times, minimizing the need for energy-intensive infrastructure.

3. Eco-Performance That Supports ESG Goals

Th NovaGenesis design makes it an attractive option for research teams looking to advance sustainability commitments.

·         No hazardous by-products – avoids harmful compounds such as ethylene chlorohydrin and ethylene glycol.

·         Reduced direct emissions – removes toxic gas leaks from lab operations.

·         Lower energy demand – operates at lower process temperatures compared to autoclaving.

·         Supports ESG reporting – contributes directly to metrics for carbon footprint reduction, waste minimization, and safer chemical handling.

4. Superior Material Compatibility

Traditionally, sterilization has required a compromise between microbial inactivation and material preservation. With scCO₂, research teams can minimize this trade-off, creating opportunities to test even the most delicate materials in controlled conditions.

·         Low-temperature process – operates below physiological temperatures in a chemically inert environment.

·         Material-friendly – reduces risks of deformation, protein denaturation, or unwanted surface chemistry changes in many sensitive materials

·         Broad compatibility – suitable for advanced substrates such as collagen scaffolds, biodegradable polymers like PLA and PCL, and early-stage prototypes.

Researchers are turning to scCO₂ because it offers a combination of speed, sustainability, and material safety in a single platform, helping them explore sterilization pathways that anticipate future regulatory and market expectations.

Flexible Solutions for Labs of Any Size

One of the most powerful advantages of NovaGenesis supercritical CO₂ technology is its scalability. While NovaGenesis itself is designed for academic and corporate R&D, the same core platform underpins larger systems (such as Nova2210 and Nova8810) that are already being used for sterilization validation studies and manufacturing applications.

This allows research teams to start small, exploring compatibility and process optimisation, with a clear pathway to scale into validated, higher-throughput systems as their needs evolve.

1. Small-Scale Research and Development Labs

For corporations, universities, and specialist research institutes, sterilization processes must be precise, accessible, and space-efficient.

·         Compact benchtop units like NovaGenesis are ideal for sterilizing small batches of new products for in-vitro analysis and animal studies.

·         Fast turnaround cycles allow researchers to prepare and reuse equipment within the same day, accelerating project timelines.

·         Minimal infrastructure requirements – no need for explosion-proof rooms, special ventilation systems, or hazardous waste handling.

2. Transition Pathways Beyond R&D

For applications beyond academic or corporate research, such as commercial manufacturing environments, larger systems (e.g., Nova2210, Nova8810) are required. These are designed to handle greater throughput while supporting regulatory and operational needs that extend beyond the R&D setting.

·         Scalable design allows facilities to grow sterilization capacity as demand increases.

·         Integration-ready systems can be incorporated into existing sterile processing workflows with minimal disruption.

·         Faster cycles improve instrument availability, reducing reliance on large inventory stockpiles.

3. Industrial-Scale Applications

Medical device and pharmaceutical manufacturers require validated, high-throughput sterilization systems that can support continuous operations. NovaGenesis itself is not intended for manufacturing use, but larger systems in the Nova series (Nova2210, Nova8810) are built to meet these demands.

·         Short cycle times allow for multiple commercial runs to be completed in an 8 hour shift

·         Validation-ready platforms support ISO-compliant sterilization studies.

·         End-to-end workflow integration streamlines production efficiency.

·         Consistent results at scale ensure reproducibility across large batch sizes.

Why scalability matters: Whether beginning with NovaGenesis in a research lab or advancing to industrial-scale platforms, the same core scCO₂ technology supports material preservation, environmental performance, and long-term innovation, enabling teams to grow without switching to an entirely different sterilization approach.

Preparing for the Future of Sustainable Sterilization

The global regulatory and sustainability landscape is evolving faster than ever across all industries. Sterilization technologies that were once considered acceptable as “industry standard” are now under scrutiny. Ethylene oxide (EtO), in particular, faces tightening restrictions due to its toxicity, environmental footprint, and public health risks. In the United States, the EPA has mandated stricter emissions controls, while the European Union and the UK have introduced lower permissible exposure limits.

For research teams, and manufacturers, this shift presents both risk and opportunity. Early adoption of alternatives like scCO₂ allows organizations to explore sustainable pathways today, while building knowledge and capacity that will smooth the transition when stricter regulations make change unavoidable.
