Case van Genuchten turns arsenic waste into a valuable raw material (he's an environmental engineer) | Socializing with Scientists
Case was a regular California kid: he skateboarded, he surfed, and he also liked math. He tried a few different majors in college, but finally found his...
Support #ScienceJournalism and give this a listen! Fun talk with @socwithsci.bsky.social podcast about all topics - from childhood to a scientific career, from California to India and Denmark and converting widespread arsenic contamination to #CriticalRawMaterials & arsenic-bearing #Semiconductors.

Grateful to the Independent Research Fund Denmark for supporting this idea. Without their support in this unconventional approach, this milestone would not have been possible.

Promising experiments to synthesize semiconductors from this upcycled As(0), which originated as toxic arsenic in drinking water, are already underway at @maxivlaboratory.bsky.social .

This work opens the door to a new idea:
that a public health liability (arsenic in drinking water) can become a high-value functional material (arsenic-bearing semiconductors).
It’s a potential breakthrough in the sustainability and economics of arsenic treatment.

But what if those same treatment by-products could be transformed?
In this study, we show that arsenic residues can be converted into pure amorphous metallic arsenic (As(0)), which is a critical raw material for digital and clean energy technologies.

Arsenic has long been viewed only as a toxic contaminant. It is a carcinogen that endangers millions through contaminated groundwater.
Even when removed, it leaves behind arsenic-rich sludges that are costly and hazardous to manage.

After 15 years of thinking about arsenic treatment and sludge management, we’ve finally reached a milestone!
Our new work, published in #ScienceAdvances, presents a concept that reimagines what arsenic can be.

Commodifying a carcinogen: Critical raw materials from arsenic-laden groundwater
Toxic groundwater treatment waste is converted to valuable arsenic metal, a critical material for clean energy and digital tech.

Memorable day yesterday at #ACSSpring2025
Even when I see the award citation, it is still hard to believe we have gotten this far with valorizing arsenic ... The next step? #semiconductors from #arsenic laden waste
Thanks ES&T for the motivation to continue this work

Excited to be back in San Diego for #ACSSpring2025 plus some ☀️ and🏄. Just finished practicing my talk on arsenic valorization for tomorrow's ES&T Award Symposium! See you tomorrow 👋
