Green Education - Sustainable Innovations


Personal Note From Patrick, The Editor

Hello Reader, do you remember a moment when a new innovation completely stunned you?

Back when I was a student, I often wondered:

What are companies and institutions actually doing to support sustainable science?

I never really took the time to look it up... But later, I discovered just how many exciting solutions already exist.

So today, I want to share a few of them with you.


Today's Lesson: Innovations that Inspire

Discovering what makes our science more sustainable


Number Of The Day

In a group monitored by Freese et al., a single researcher used around 8 470 pipette tips per year. In total, the 17-member team generated 533 kg of plastic waste annually—about 2.6 kg of tubes, tips, plates, syringes, and other plastic items per person per month. Moreover, they found that their two-week student practical course alone consumed 45,000 tips. If extrapolated, that’s 90,000 tips per year—equivalent to 7 tips per student per day.

8470


Reducing the Impact of AI

There are several innovations designed to make science more sustainable.

While I’ll be sharing many more in the coming weeks, here are three that I think you should know about right away:

1. Biobased Pipette Tips

Eppendorf has recently launched its new line of biobased pipette tips, composed of 90% biobased or recycled feedstock, primarily derived from plant oil waste, and 10% conventional fossil-based plastic.

How much more sustainable is that alternative?

For a standard full product unit— 10 boxes (0.1–10 μL tips):

  • Fossil-based tips produce 2.962 kg CO₂e
  • Biobased tips produce 2.129 kg CO₂e (28% reduction)

If we only look at a single tip, one fossil-based tip = 3.09 g CO₂e while one biobased tip = 2.22 g CO₂e.

The other factors enabling the overall savings are:

  • A 35% reduction comes from an improved container design
  • A 15% reduction comes from better packaging
  • And most impressively, a change in sterilization logistics reduced emissions from transport by 72%

While a 68% reduction in emissions due to the switch in tip material is impressive, this is a strong example of what’s possible when a manufacturer optimizes across multiple points in the product lifecycle.

2. Helium Recovery - From Crisis to Innovative Solution

Helium is used to cool the superconducting magnets in NMR and MRI systems down to 4.2 Kelvin (-269°C).

Although helium boil-off is minimal during routine operation, it spikes significantly during refills—and for many labs, that helium was simply lost to the atmosphere.

In 2018, the global helium shortage sent prices skyrocketing from $6 to over $18 per liter. In 2022, even Harvard University had to suspend several research projects due to a 50% reduction in helium supply.

And it’s not just costly—restarting an MRI can exceed $100,000, take several days, and in some cases, NMR magnets may be permanently damaged.

Early initiatives (some dating back before 2017) required institutions to build their own helium recovery infrastructure—collecting, storing, purifying, and reliquefying helium to keep it in a circular system.

Today, companies like Bruker or Quantum Design offer pro- and retrofit systems that achieve 85–95% helium recovery.

Even better, Bluefors recently introduced a compact solution designed for a single NMR machine, making recovery feasible for small labs for the first time. And just like energy-efficient freezers, smaller-scale systems also use less energy, saving money and reducing emissions.

3. Outside the Lab

I recently came across an innovation I had to share. Between 2001 and 2010, New York City dropped 2,500 retired subway cars into the ocean.

Of course, these cars were cleaned and stripped of pollutants before being submerged. The goal? To create artificial reefs.

Here’s how it works:

  • The hard surfaces attract corals and marine plants
  • Invertebrates like mussels settle in, creating habitats and food chains
  • Over time, these reefs produce significantly more food than a barren seafloor

That said, the project wasn’t without controversy. While reliable sources are scarce, concerns have been raised that iron release, especially in iron-poor waters, may disrupt marine ecosystems. Also, critics have claimed that water temperatures off the U.S. coast are too cold for substantial coral growth.

Still, projects like Redbird Reef appeared successful. The project was eventually discontinued—not due to ecological failure—but because modern subway cars contain too much plastic, making cleaning and refurbishing too expensive.

Applying The Knowledge

In my experience, progress toward sustainability is limited as much by lack of awareness as by a lack of solutions.

But remember, there’s no perfect innovation. While it is difficult to estimate long-term effects in the reef example, helium recovery requires material-manufacturing and energy. Financially, it is an investment, often taking 5+ years to break even.

Nevertheless, don’t underestimate how much companies are doing behind the scenes to create a more sustainable future!

Personal Note from Patrick, the Editor Hi Reader, you are probably missing out on significant opportunities... Institutions that take sustainability seriously can often save more than 60% of plastic waste, 50% of energy, and 20% of chemicals. Even if you have, for example, set your freezer to -70°C you are still missing out on about 1/3 of potential energy savings. How is that possible, and how can you change it?

Personal Note From Patrick, The Editor Hi Reader, I’m sure you’ve heard of bioplastics. Previously, we already discussed what they actually are. But are they safe to use in the lab? I would argue generally yes, apart from two specific exceptions: Today's Lesson: The Safety of Bioplastics Investigating the properties of innovative plastics Number Of The Day Life Cycle Assessments indicate that biobased polypropylene can reduce footprints by up to 81%. While the actual numbers in manufacturing...

Personal Note From Patrick, The Editor Hi Reader, ever thought about reusing your tips or tubes? To do so, many laboratories autoclave them to ensure they are sterile. However, autoclaving takes time and energy - it’s at least 121 °C for 30 minutes, after all. So, does reusing items actually make sense?
