A discovery born almost by chance, but destined to change the relationship between man and the environment. The research team led by Elza Bontempi of the University of Brescia has developed a new material, the result of recycling of used lithium batterieswhich could give new life to CO2 sequestered by industrial processes. Published in the magazine EnvironmentalResearchthis innovation promises to recycle industrial CO2 transforming it into a resourceconcretely contributing to environmental sustainability and the fight against climate change.
But how did all this come about? We are not talking about long years of planned research, as Bontempi explains, underlining that everything started from a process that aims to extract precious metals such as nickel, manganese, cobalt and lithium from spent batteries, using a microwave oven:
It was a stroke of luck, a discovery by serendipity.
And here’s the twist: among the final products of the process, a mysterious pink compound appeared.
How AI accelerated the discovery of an innovative material
To identify that never-before-seen compound, the company intervened advanced technology. “Artificial intelligence is usually used to analyze huge amounts of data and suggest new materials with specific characteristics. In this case, however, it was fundamental to identifying what we had in front of us,” explains Bontempi. It was an approach collaborativein which the AI worked side by side with the researchersspeeding up a process that would otherwise have taken much longer.
But that’s not all: the AI also suggested a number of possible applications for the new material. Among these, the most promising is the use as catalyst for CO2which is a means of transforming carbon dioxide into new useful chemical compounds. In short, not only reduce the impact of CO2, but actually transform it into a precious resource.
Recycling, innovation and sustainability
This project represents a concrete example of circular economy: from industrial waste such as spent batteries and seized CO2, it is possible to obtain innovative and sustainable materials, as Bontempi states:
Our work demonstrates how technology can be put at the service of sustainability, with a view to the energy transition.
The team, which includes collaborations with the University of Catania and Milan-Bicocca, is now verifying the predictions provided by AIopening up scenarios that could revolutionize the recycling sector. The discovery, in fact, not only favors the reduction of CO2 emissions, but allows valorise waste materialscombining science and technology for the good of the planet.
A virtuous example that reminds us how even from the most difficult problems – such as battery disposal and carbon dioxide emissions – we can draw an opportunity for the future.
