The Powerful Possibilities of Recycling the World’s Batteries | Emma Nehrenheim | TED
The world has plenty of clean energy. The problem is storing that energy and getting it where we need it, when we need it, says battery recycling pioneer Emma Nehrenheim. While batteries are fundamental to powering a sustainable future, their production is surprisingly harsh on the environment. She lays out the science behind a breakthrough…

I hope that Elon musk jumps on this bandwagon. There are so many dead Tesla batteries that they don’t know what to do with yet.

And just two days ago two battery recycling plants in Canada shut down. Another reason why we are not ready for widespread adoption of EVs. It’s going to cost billions, if not trillions, to prepare our electric grids over the next decade or two.

Boo hoo hoo, we are not ready for new technology because we didn’t prepare. That’s not a good reason to not prepare.

She is absolutely right. Fossil fuels is already killing our planet. We need to do things safely for the advancement of clean energy. ❤

But almost everything is made from fossil fuel. I don’t it’s even possible to have clean energy w/o fossil fuels which defeats the purpose lol

Y’all gotta take that Sue Klebold talk down straight up a delusional woman playing victim and hiding from accountability. That talk is not intellectual in any way and it’s not educational, it’s the opposite. It’s manipulating the truth and the past to avoid responsibility, and its disrespect to the victims. Right your own wrongs and take the damn talk down.

00:08 🌍 Batteries play a crucial role in enabling the use of clean energy by allowing its storage and transportation.
01:09 ⛏ Historically, we have extracted resources like oil without considering long-term consequences, contributing to environmental crises.
02:10 🏭 Battery manufacturing consumes large amounts of energy and relies on global mining, refining, and complex supply chains.
03:44 🔄 Putting battery manufacturing under a renewable energy grid significantly reduces its carbon footprint, but challenges remain in the supply chain.
04:45 🌿 Sustainable mining and recycling can greatly reduce the environmental impact of battery production.
05:42 ♻ A recycling process can recover materials from used batteries, creating a circular battery economy.
07:44 ⚙ The circular economy approach should be extended to other industries, such as wind turbines and solar panels, for a sustainable transformation.
08:39 💰 Implementing recycling and traceability systems is not only environmentally beneficial but also economically profitable, as materials retain their value over time.

Nailed it, and when you start with a old battery you already have all the resources needed to make a new one. Batteries, solar panels etc can be recycled, we just aren’t up to speed with the infrastructure to do it.

As long as slave labor is used to mine the minerals needed to make batteries, recycling will not be economically feasible.

Amazing! We are building shredder for all kinds of material. I think we should concentrate more on batteries
Toby O'Hara

This is a very important message, I’m glad we are talking about it. I hope we also start to implement mechanical batteries, which will ease pressure on mining. Mechanical batteries include, weights and pulley, pumped air, pumped hydro, flywheel, and springs.

Battery recycling is already done by some companies but it hasn’t been done in large scale by everyone because it is costly and that it’s not being funded properly by the government and also soecial interest groups like oil companies feed false information to the poorly educated to think that it is not possible when in fact it is. Take a look at conservatives in the US, they believe that windmills and other renewables can’t power a country but norway and Iceland proved them wrong because they are nearly renewable powered

We are going to “mine” the ocean floor to keep up with battery demands. Finally killing our survival in long term.

People tend to gloss over areas they shouldn’t gloss over in their pursuit of a pushing an idea. In this case the idea is how its great to have batteries and run the world on electricity. The elephant in the room is how are we going to generate the electricity to power all these vehicles. The fact is that the electrical grids can not handle running the world on electric cars. And more electric cars means more oil, and coal burning.

No recycle opperation is terribly efficient. Materials get degraded as they are mixed with impurities. I guess well have to make due until molecular sorters can get invented.
