In the world of technology, old gadgets often end up as trash, but they hold a secret treasure. Rare earth elements (REEs) found in discarded electronics are in high demand, but extracting them is tough. A group of scientists has found a smarter way to do this. They use electricity to heat up old magnets quickly and chlorine gas to separate the useful parts from the ...
China is making big moves to handle old electric vehicle (EV) batteries in a smart and eco-friendly way. The country has set up 22 national standards to guide how these used batteries should be managed, taken apart, and tested. These rules are helping companies recover up to 99. 6% of valuable materials like nickel, cobalt, and manganese, and 96. 5% of lithium. This ...
Plastic waste is a big problem. Sorting it correctly is super important for recycling to work well. Right now, most systems use fancy cameras or big computers that aren't very flexible. This makes recycling expensive and not very good at handling different types of plastic. A new study looked at a different way to sort plastics. They used something called Federated ...

First, let's talk about the scale of the problem. A detailed look at 21 construction site...
Electronic waste is a big problem. It's full of valuable metals that can be reused. One way to get these metals is through bioleaching. This process uses tiny organisms to pull out metals from waste. A recent study focused on getting pure copper from old printed circuit boards. This is important because copper is used in many things, like wires and electronics. The ...
Renfrow, a former standout wide receiver for the Las Vegas Raiders, is now making waves in a completely different field. He is no longer known for his precise route-running or clutch plays, but for his new role as a recycling advocate.

The world of bike-sharing has brought plenty of good things, like easier commutes and less traffic. But it has also left behind a problem: what to do with all the old bike frames that get thrown away? This issue is not just about trash. It is about finding new uses for these frames, especially in rural areas that need help. Most people do not know that these frames c...
Plastic recycling is a hot topic these days. One exciting development is the use of zinc-based networks to break down a common plastic called PET. These networks act like super-efficient catalysts, speeding up chemical reactions without getting used up themselves. They turn PET into something valuable: terephthalic acid. This process is a big deal because it helps r...
China is a massive player in the plastic industry, but there's a lot more to the story than just the usual suspects like PE and PP. There are 12 types of non-commodity plastics that don't get as much attention. These plastics are tricky to define and track, making it hard to figure out how much is made, used, and what happens to them at the end of their life. This...
