Why correct battery recycling matters

Learn incorrect battery recycling risks and protect communities, waste collection workers and environments

Everyday batteries and hidden dangers

Most of us throw away batteries without really thinking about it, even though they are present in devices we use almost daily, toys, remotes, toothbrushes, headphones and vapes. Many of these items end up in general waste, alongside everyday packaging.

Incorrect disposal of batteries can have serious consequences, both in the short term and over time. From fires in collection lorries that endanger communities, to long-term environmental pollution caused by leaking chemicals, the hidden risks can be significant.

Burnt batteries

Battery fires are increasing

Recently, there have been notable incidents in Norwich, Warwickshire and Loughborough. Disposal company Biffa says battery-related fires have increased by 70% in the last four years, causing more than £1 billion in damage annually.

These fires commonly occur in bin lorries and sorting facilities when batteries become crushed or damaged during waste collection and processing. This can trigger internal short circuits and a rapid chemical reaction known as thermal runaway, where the battery overheats and ignites.

The immediate impact

In the short term, battery fires create immediate danger for waste collection crews, recycling workers and the public. Incidents can lead to road closures, emergency callouts and disruption to waste services.

There is also a major financial impact. With each bin lorry costing around £300,000, fires can be both operationally disruptive and extremely expensive for councils. Beyond repairing or replacing vehicles, there are additional costs linked to emergency responses, missed collections and service disruption, costs that can ultimately affect taxpayers.

The long-term environmental risks

The longer-term risks are less visible, but potentially even more serious.

When batteries are damaged, harmful chemicals can leak into soil and groundwater, eventually reaching rivers and drinking water supplies. Over time, these pollutants can harm wildlife, affect ecosystems and reduce soil fertility.

Different battery chemistries pose different risks:

  • Lead and mercury can contribute to serious brain and developmental problems
  • Cadmium has been linked to kidney damage and weakened bones
  • Nickel and lithium may cause skin irritation and respiratory issues

Children can be particularly vulnerable through indirect exposure from contaminated water, food, soil and dust. The long-term impact is especially concerning because pollution can accumulate gradually over time without obvious warning signs.

How we can reduce the risks

We can still reduce these risks by improving battery recycling habits and raising awareness.

Simple actions can make a significant difference, including:

  • Taking batteries to designated recycling points
  • Never placing batteries in general waste bins
  • Safely storing loose batteries
  • Taping battery terminals where recommended

Encouraging others to recycle batteries correctly can help prevent avoidable fires, protect waste workers and reduce environmental harm.

The more people who understand the risks, the more likely we are to see positive changes in everyday disposal habits.
