Vape, la miniera urbana che i mercati non hanno ancora capito
https://www.metallirari.com/vape-miniera-urbana-mercati-non-hanno-capito/
I vape non sono solo un problema sanitario o ambientale: al loro interno contengono litio, cobalto, nichel e rame che ogni settimana finiscono nei cassonetti anziché nelle filiere di recupero.

#Winemaking acid powers cleaner way for cobalt-nickel recovery from #BatteryWaste

Scientists use #TartaricAcid and electrowinning to split #cobalt and #nickel from battery waste for cleaner #recycling.

"Scientists have developed a cleaner way to separate cobalt and nickel from lithium-ion battery materials using an electrochemical technique boosted by a naturally occurring acid commonly associated with wine.

[...]

"The researchers say the approach could be particularly useful for '#UrbanMining,' the process of recovering valuable #minerals from discarded #electronics and spent #batteries. Countries with limited mining resources are increasingly looking to #recycling to secure supplies of critical materials.

" '#Electrowinning’s edge in urban mining gives us a practical pathway to turn battery waste into a valuable resource for cobalt and nickel, while also helping the United States reduce its reliance on foreign supply chains,' Liu says."

Bioacid-powered process pulls cobalt, nickel from old batteries

Wine-making acid helps scientists separate cobalt and nickel from battery waste using electrowinning technology.

Trash Talk – aber sinnvoll.♻

Der Großteil alter Geräte wird nicht offiziell gesammelt oder recycelt. Dadurch gehen wertvolle Rohstoffe verloren – und viele Geräte landen auf Deponien oder werden unsachgemäß verarbeitet.

Cities are starting to mine their own junk. Little facilities pulling rare earths out of dead electronics instead of shipping the mess overseas. It makes the hidden guts of digital culture visible again. Still small, pilot stuff, mostly civic-funded. Recycling PR? Uh uh. Greenwashing? Nope.It’s early infrastructure for keeping your own material loops local.

Ich habe keine Bewerbung geschrieben. Keinen Termin vereinbart. Trotzdem sitze ich jetzt in diesem Beirat.

Auf der Dach+Holz habe ich die Projektleiterin des EFRE‑Projekts „Kreislaufgerechtes Bauen mit Holz“ kennengelernt. Jetzt bin ich als Tragwerksplaner und als Vertreter der IKBau NRW im projektbegleitenden Beirat.

Technisch ist kreislaufgerechtes Bauen mit Holz lösbar. Was bremst, sind unsere Rahmenbedingungen.

This weekend we found more nerf darts but they were broken so it was more of a #plogging thing than #urbanmining
To be honest I'm not sure what upsets me more. Leaving broken stuff out in nature or leaving usable stuff 🤔 I guess it's just both a bit upsetting.
Found another vape thrown into the grass 😒 This time is quite a chunky one. Has a USB port for recharging but nothing to load more liquid it seems. Curious whether the charging circuit is separate from the rest of the electronics so I could potentially reuse it 🤔 #urbanmining
