When it comes to sustainability in biobanking, the impact goes beyond the laboratory.
Liquid nitrogen (LN₂) plays an important role in preserving biological samples at cryogenic temperatures. But have you considered the energy and transportation required to produce and deliver it?
These activities can contribute to Scope 3 emissions, the indirect emissions associated with its supply chain and supporting operations.

So, where can organizations start?
Evaluate sample storage requirements and processes.
Review delivery schedules and opportunities to consolidate LN₂ orders where practical.
Measure the environmental impact of current storage practices to identify opportunities for improvement.

Sustainability isn't about compromising sample integrity. It's about understanding the full picture and making informed decisions wherever improvements are possible.
At Stirling Ultracold, we're passionate about advancing the conversation around sustainable cold storage and helping laboratories consider the impact of the technologies and processes they rely on.

Over the last two days, we connected, we learned, we shared, and we enjoyed all being together for our annual sales team meeting!! We even kicked off night 1 with a company cookout.
It's always nice to get out of the day-to-day routine and discuss our individual challenges, successes, and opportunities! We have the best team in the industry and we really enjoyed having everyone at our Athens plant this week!

What if your cold-chain cooling material could be reused instead of replaced?
Phase Change Material, or PCM, offers an alternative approach to traditional dry ice for certain temperature-controlled transportation applications.

Some -70°C PCM solutions can be recharged and reused in a freezer rather than manufactured and consumed for every shipment.
That creates an opportunity to rethink the role of passive cooling in sample transportation.

Instead of:
Use → Ship → Discard → Replac

PCM can support a:
Recharge → Reuse → Ship → Recharge
approach.

The sustainability benefit comes from reducing reliance on single-use dry ice and the energy associated with producing it.
For organizations working to address Scope 3 emissions, reusable PCM is one technology worth exploring.

Dry ice keeps samples cold. But have you considered the energy required to make it?
When evaluating sustainability in biobanking, it's easy to focus only on what happens inside the laboratory. But sample transportation can have its own environmental footprint.

Dry ice requires energy to manufacture, and its production contributes to Scope 3 emissions associated with the supply chain. If your organization is looking for ways to reduce Scope 3 emissions, transportation and passive cooling deserve a closer look.

And that raises an interesting question:
Is there a reusable alternative to single-use dry ice for some applications?
That's where Phase Change Material, or PCM, comes into the conversation.

Scope 3 emissions can be easy to overlook and are often confusing. Why? Because they're not necessarily coming from something you own or operate.

Scope 3 can include emissions associated with:
• Sample transportation and logistics
• Dry ice production
• LN₂ generation
• Supply-chain activities
• Equipment and materials
• Transportation
• Other upstream and downstream activities

That means reducing your environmental footprint requires looking beyond the walls of the facility.

The question becomes:
Where else are emissions being generated throughout the lifecycle of our samples, equipment and processes?
Once those sources are identified, organizations can begin looking for opportunities to reduce them.

Ultra-low-temperature storage can operate around the clock, making energy efficiency an important part of the sustainability discussion.

There are two ways to think about it:
How much electricity is the equipment using?
How is that electricity being generated?

Reducing the amount of electricity required by cold storage can help reduce the associated emissions, particularly when that electricity is generated from higher-emission sources.

More efficient cold storage isn't simply about lowering an energy bill. It's also about reducing the environmental impact associated with operating the equipment every day.

Where does your cold storage equipment fit into your sustainability strategy?
Scope 1 emissions are direct emissions from sources an organization owns or controls.
That means taking a closer look at the equipment and processes operating within the facility.
Cold storage is an important part of that conversation. Older ultra-low-temperature freezers can consume significantly more energy than newer, more efficient models, and the heat they reject into the room can also increase the load placed on the facility's HVAC system.
That means the sustainability conversation shouldn't stop at:
"How much energy does my freezer use?"

It should also include:
"How does my freezer affect the environment around it?"

Improving equipment efficiency can help reduce energy consumption while also reducing the amount of excess heat introduced into the laboratory.
Sustainability starts with understanding the complete system, not just one piece of equipment.

When it comes to sustainability in biobanking, where do you even begin?
One place to start: understanding your Scope 1, Scope 2 and Scope 3 emissions.

🔹 **Scope 1 — Direct emissions**
These come from sources directly owned or controlled by an organization. In a biobank, that can include emissions associated with equipment and refrigerants.

🔹 **Scope 2 — Purchased electricity**
This is the emissions associated with the electricity your facility purchases and uses to operate its equipment, including cold storage.

🔹 **Scope 3 — Indirect emissions**
This is where things get broader, including supply chain activities, logistics, transportation, materials and other indirect sources.

For biobanks, sustainability isn't just about the freezer sitting in the lab. It's about looking at the entire lifecycle and process surrounding sample storage and transportation.

The first step toward reducing emissions is understanding where they come from. At Stirling Ultracold, we're continuing to explore how cold storage technology and smarter processes can support more sustainable laboratory operations.

What's the Real Cost of an Ultra-Low Temperature Freezer?
When evaluating a ULT freezer, it's easy to focus on one number:
The purchase price.
But what if that's only part of the story?

A freezer is a long-term investment that continues to incur costs long after it arrives in your laboratory.

The real life cycle cost can include:
Energy consumption — A freezer that operates 24/7 can have a significant impact on your facility's energy usage.
HVAC costs — The energy consumed by a traditional compressor-based freezer is ultimately released as heat into the building, adding to the cooling load on your HVAC system.
Floor space — Laboratory space comes at a premium. The footprint of your freezer, and how much storage you get for that footprint, can have a meaningful impact on your facility.
Maintenance and replacement costs — Components and service requirements over the life of the freezer can add significantly to the total cost of ownership.
Storage capacity — The amount of usable storage you get from the equipment matters, too. A freezer that maximizes storage while minimizing its footprint can provide greater value from the space you already have.

That's why comparing ULT freezers based solely on the initial purchase price doesn't always tell the whole story.

At Stirling Ultracold, we believe laboratories should look at the total cost of ownership when making a cold-storage investment.
Our energy-efficient free-piston Stirling engine technology, compact designs, and focus on storage density are all part of that equation.

The result? A ULT freezer should be evaluated not only by what it costs to purchase, but by what it costs to own and operate over its lifetime.
