Battery Recycling – Small Objects, Big Problem

 


Battery Recycling – Small Objects, Big Problem

Batteries are one of those things we barely notice until something stops working. The remote fails, the kitchen scales go blank, the torch gives up during a power cut, and suddenly we are rummaging in the “useful drawer” for replacements. But once the old batteries are dead, what happens next matters far more than most people realise. In the UK, batteries should not just be chucked into the bin, because when they are crushed in waste lorries or sorting plants they can cause dangerous fires. Campaigns run by Material Focus and recycling bodies keep repeating the same message for a reason: binned batteries are a genuine fire risk.

That is especially true now because so many everyday gadgets contain lithium-ion batteries. They are in phones, laptops, power tools, toothbrushes, toys, headphones, e-bikes and a growing mountain of small rechargeable devices. Some batteries are obvious and easy to remove. Others are hidden inside products, which makes them even more likely to be thrown away by mistake. Material Focus and fire services have both warned that batteries hidden in electrical items are helping to drive fires in bins, recycling lorries and waste sites.

The frustrating thing is that batteries are far too valuable to waste. They contain useful materials that can be recovered and reused, reducing the need to keep mining for more raw materials. That is one reason battery recycling is becoming more important across Europe. The EU Batteries Regulation, which came into force in 2023, is designed to make batteries more sustainable, more circular and more recoverable, and new rules published in July 2025 set out how recycling efficiency and material recovery should be calculated and verified.

For households, the good news is that recycling batteries is not difficult. Recycle Now says all household batteries can be recycled, including button batteries, and many councils or local collection schemes accept them separately from normal recycling. If your council does not collect them from home, there are often battery recycling points at supermarkets, shops and household recycling centres. Recycle Your Electricals and Recycle Now both provide postcode locators to help find the nearest drop-off point.

There are a few sensible habits worth getting into. First, never throw loose batteries into the household bin. Second, check whether your local authority wants them placed in a separate clear bag for collection, because councils vary. Third, remember that products with a plug, battery or cable should usually be treated as electrical recycling, not ordinary rubbish. And fourth, if you are replacing an electrical item, many larger retailers will take the old one back for recycling when you buy a new one.

It is also worth being careful with damaged rechargeable batteries. A swollen battery, overheating device or battered e-bike pack is not something to toss casually into a bag and forget about. Damaged lithium-ion batteries can be particularly hazardous. Fire services warn that once damaged or crushed, they can ignite fiercely and spread very quickly.

So battery recycling is not just a worthy green habit. It is one of those rare actions that is easy, sensible and safer for everyone involved. It cuts waste, helps recover useful materials, and reduces the risk of fires in the waste system. For something so small, a battery can cause a surprising amount of trouble in the wrong place. Far better, then, to keep a little container at home for dead batteries and take them to the right collection point now and then. It is not glamorous, but neither is setting fire to the bin lorry.

Using Ecosia: The Search Engine That Plants Trees

  Using Ecosia: The Search Engine That Plants Trees ( Click. Search. Plant. Repeat. ) Imagine if every time you googled something, you planted a tree. No, it’s not some kind of green-tech fantasy — it’s Ecosia , a real search engine that uses its ad revenue to fund global reforestation projects. And all it takes is changing your browser’s homepage. What Is Ecosia? Ecosia is a free, privacy-respecting search engine based in Germany. It works just like Google or Bing, but with a twist: They use 100% of their profits to plant trees. So far, they've funded over 180 million trees in places like: Brazil Burkina Faso Madagascar Indonesia Kenya All you have to do is search the web. That’s it. You search — they plant. How It Works Every time you search on Ecosia, the platform earns revenue from clicks on sponsored search results (just like Google). Roughly 45 searches = 1 tree . The money goes to vetted reforestation projects with a focus on: Native bi...

New Filtration Technology Could Be a Game-Changer in Removing PFAS “Forever Chemicals”

New Filtration Technology Could Be a Game-Changer in Removing PFAS “Forever Chemicals”  PFAS – often called “forever chemicals” – have a nasty habit of doing exactly what their nickname suggests: they don’t break down , they build up in the environment, and they accumulate in our bodies. Used for decades in non-stick cookware, waterproof clothing, firefighting foams, food packaging and industrial processes, PFAS are now found in rivers, groundwater, drinking water – and even rain . The scale of the problem has felt overwhelming. Until now. A breakthrough from the lab Researchers at Rice University have developed a new filtration material that could dramatically change how we deal with PFAS pollution. Their peer-reviewed research describes a layered double hydroxide (LDH) material made from copper and aluminium that can: Absorb long-chain PFAS up to 100× faster than current filtration systems Target the most persistent and dangerous PFAS compounds Potentially destr...

Does economic growth have to mean rising emissions?

  Does economic growth have to mean rising emissions? For decades, we’ve been told there’s an awkward trade-off: grow the economy or cut emissions – pick one . It’s a neat story. It’s also increasingly out of date. The uncomfortable truth for that old argument is this: several countries are already growing their economies while cutting emissions . Not hypothetically. Not on a whiteboard. In the real world. The old assumption (and why it stuck) Historically, growth did mean more emissions. Industrialisation burned coal, oil powered transport, and cheap energy meant dirty energy. GDP and carbon rose together, so the idea became baked in: prosperity equals pollution. But that logic assumes three things: Energy must come from fossil fuels Efficiency improvements are marginal Consumption can’t change None of those assumptions still hold. What “decoupling” actually looks like Economists talk about decoupling – separating economic growth from emissions. There are two...
