Scientists have devised a method to upcycle lithium-ion batteries and expired solar panels into new solar cells. The method recovers valuable materials from the waste and converts them into perovskite solar cells, which are cheaper and more efficient than silicon-based ones. This could reduce the environmental impact of electronic waste and boost the renewable energy sector.

"Schools have piles of working Chromebooks that have become e-waste because they’ve expired." #ewaste #Chromebooks

So, I found a KVM switch in the eWaste bin (well, five, but the other 4 went to an actual good home, instead of my chopping block.

So let's tear into it!

@izaya if you pay €0,62/kWh like is the basic rate in Germany, you'll yeet that old piece of Cisco junk right on #eNay if not the #eWaste recycler in your juristiction...

@gerrymcgovern @Brad_Rosenheim @shepgo

Then maybe don't even look at the #eWaste-Producing #Shotshow that is the #1 #Shitcoin aka. #Bitcoin :bitcoin: where millions of ASICs get made that can't be repurposed in any shape or form unlike a CPU, GPU or even FPGA...

Two simple way to reduce the likelihood of semiconductor storages *and* reduce the volume of e-waste we have to deal with.

1) Oblige vendors to guarantee N years of useful life for electronic goods, and advertise price-per-year of life alongside purchase price. This could reduce the wastage of semiconductors in disposable electronics, and help people avoid being ripped off by the designer landfill that's misleadingly marketed as being cheaper.

Good piece in WSJ about Chromebooks' short shelf life meaning they rapidly become e-waste. Schools have to pay to have them carted off when they die after 3 years. (Low management costs while in operation still are notable advantage vs Mac/Windows PCs IMO.) https://www.wsj.com/tech/personal-tech/chromebooks-were-once-a-good-deal-for-schools-now-theyre-becoming-e-waste-dc93833b

@codekoan Also people demand #Repairable devices not only because they like #repairability and hate avoidable #eWaste but most people in the #USA can't even afford a surprise $400 expense.

So it makes total sense to choose something cheaper that if it breaks can be repaired cost-effectively - like a @Fairphone ...

@cannaclub I am all for #Cannabis and cannabis-related products, but disposable vaping products contribute to plastic and electronic waste, a problem that we are currently overwhelmed with. Products like this should not exist because they just end up in landfills or as litter, and people should not be purchasing them.

MacOS is beautiful and so is Mac hardware. However, you should never purchase anything from a company that fakes signs of an unsuccessful repair when there is nothing wrong with the replacement component. Apple is intentionally designing its products to become e-waste. #RightToRepair #eWaste #CircularEconomy

🚭 Please boost if you want @EU_Commission to start discussing a #ban of #disposable #ecigarette

#vaping single use e-cig is becoming a real issue among young people, it increases #ewaste and does harm nature by releasing harmful substances.

Unlike :bitcoin: #Bitcoin it's not #eWaste per design in the sense that only #greed justifies their existance...

@futurebird As sad as it sounds, this #disposable #logger isn't #eWaste because it's desired but because it's the cheapest solution to "have audotable temperature logging".

This is probably the coolest thing I've ever seen!! Mechanical Apple Watch made from e-waste. Great video!!

Before the current epidemic of disposable vape pens, Poundland used to sell these disposable phone chargers which had a 650mAh #lithiumPolymer battery connected to a DC-DC boost converter. There was no straightforward way for owners to recharge them.

I've been distracted by e-cig battery harvesting, but finally got around to adding a TC4056A module with over-discharge protection to the few I bought back then

They are now just like USB #rechargeable powerbanks

@TechConnectify And as sadly as the @EU_Commission won't adopt #IEC60906 connectors due to #eWaste I think they should make #IEC60309 mandatory for ekectric stoves and other electronics that require more than 230V @ 16A single-phase and ain't installed into the wall like some pass-through boiler/heater...

What is your view on buying modular computers with the ability to repair or replace parts in an effort to reduce #ewaste?

We talked to Oliver Franklin-Wallis about his new book, Wasteland 📚 ⁠

Oli spent four years researching waste of all kinds, the people that handle it, and its effect on our planet incl. visiting a Restart Party! 🔧💚
