Here at FP International, we take an active interest in sustainability and protecting the environment. While we do what we can to minimize waste with eco-friendly void fill materials, landfills are only one contributor to a major issue: global warming. Where we trap air in layers of biodegradable* plastic, a power plant in Iceland is upping the ante trapping greenhouse gases into rock. But before we elaborate on that sorcery, let’s first take a look at the problem.
CO2 emissions associated with retail and ecommerce product pathway stages.

Digital retailing, for example, has helped cut down CO2 emissions tremendously, removing a large chunk of the problem: customer transport. For businesses grounded in the physical world, reinventing packaging and rethinking sustainability are also strong steps in the right direction. Preventative measures are one thing, but what about the gases already released into the air?

The Hellisheidi Geothermal Power Station in Iceland has been trying to answer that very question. Their answer: CarbFix. The pilot program‘s primary goal is “to imitate the natural storage process of carbon dioxide already observed in basaltic rocks in Icelandic geothermal fields.” In layman’s terms, they want to pump greenhouse gases into porous volcanic rock and let it mineralize naturally (though with a bit of help).
While the CarbFix process might take millions of years to occur naturally, with the help of technology, it’s sped up to within two years. The injected carbon dioxide and hydrogen sulfide mixes with water and reacts with the calcium (CaO) and magnesium (MgO) oxide present in basalt. The reaction then allows the engineers to form limestone (or calcium carbonate, CaCO3) for permanent (and more importantly, leak-free) storage.
“The model actually predicted that the CO2 would turn into rock within approximately five years of injection. And actually, at that time, no one believed the models, that it was outrageous, that there’s no way it could happen this quickly. But then, turns out, it happened even faster; a stream
[of injected rock] was almost mineralized within one year.”
As the main component to this process is basalt or other similar volcanic rocks, the team hopes that other research and engineering groups around the world can adapt CarbFix in their countries, given the rocks’ abundance. While this is an exciting new technology, however, there is still a lot of work to be done.
As fantastic as CarbFix works on a geothermal power plant, the real test will come when the technology starts moving over to coal power plants. Since geothermal power plants only have a fraction of emissions their coal-fed counterparts, the question becomes less about where to put the carbon dioxide and more about how are the machines that govern and catalyze these processes going to be, in turn, powered on a large scale.
Either way, we still have a long way to go in making a meaningful impact in reducing greenhouse emissions and cleaning up the planet. As far as CarbFix goes, excess carbon dioxide might be a problem we end up burying and forgetting like we try to do with everything else. Until then, we all have our parts to play to lower of carbon footprint, even if it’s not steeped in alchemy and science fiction.
*49.28% biodegradation in 900 days under non-typical conditions; no evidence of further biodegradation.
The European Parliament voted for a complete ban on a range of single-use plastic waste across the union in a bid to stop pollution of the oceans. The proposal also called for a reduction in single-use plastic waste for food and drink containers, including plastic cups.
China has long been treated as our planet’s repository for plastic waste. The nation has accepted 45% of the world's total plastic recycling since reporting to the United Nations Comtrade Database began in 1992.
Even before plastic straw bans grew trendy, California was at the forefront of using less plastic and promoting more sustainable living. California pioneered a statewide ban on plastics beginning in 2016, when the state became the first in the U.S. to ban most stores from providing customers with single-use plastic bags, following a successful referendum.
