Cold Chain, Hot Problem: Why It’s Time to Move Beyond Styrofoam

From life-saving biologics to on-demand pharmaceuticals delivered to your doorstep, the cold chain has become one of the most critical infrastructures in modern healthcare.

But behind every temperature-controlled shipment lies a growing problem no one talks about enough:

Styrofoam is everywhere.

The Hidden Cost of Keeping Things Cold

Cold chain logistics in life sciences is expanding rapidly. With the rise of personalized medicine, direct-to-patient delivery models, and global clinical trials, demand for reliable temperature control has never been higher.

The global cold chain logistics market is projected to exceed $800 billion by 2030
Biopharma products account for a rapidly growing share of temperature-sensitive shipments
Many therapies require strict ranges between 2°C–8°C, frozen, or even cryogenic conditions

To meet these demands, the industry has leaned heavily on one material:

Expanded Polystyrene (EPS), better known as Styrofoam.

It’s cheap. It insulates well. And it’s everywhere.

But it comes with trade-offs:

Non-biodegradable and persists in landfills for hundreds of years
Difficult to recycle, with low recovery rates globally
High disposal costs for labs, hospitals, and distribution centers
Increasing scrutiny under ESG and sustainability mandates

In short, the system works, but at a cost the industry can no longer ignore.

The Standard Was Never Meant to Be Permanent

EPS became the default not because it was the best solution, but because it was the only scalable one at the time.

Today, that’s no longer true.

Cold chain requirements haven’t changed:

Maintain temperature integrity
Protect valuable samples
Ensure compliance with rigorous transport standards like ISTA 7D summer profiles

What has changed is what’s possible.

Introducing a New Category: Sustainable Cold Chain Performance

At PulpFixin®, we saw the gap clearly:

Why is the most advanced science in the world still being shipped in the least sustainable material?

That question led to the development of FeatureFoam™ Cold Chain Shippers, a new category of insulation that eliminates Styrofoam without compromising performance.

According to our product data and testing:

Outperforms EPS insulation of equal thickness
Maintains thermal integrity beyond 72-hour ISTA 7D summer profiles (validated testing)
Capable of extending performance up to 96 hours under real-world conditions
Manufactured using BPI and TÜV-certified compostable materials
Meets ASTM D6400 and D5338 compostability standards
