We would not tell you anything new by stating that batteries are not any other junk, so their disposal is not to be approached in the same way that we usually approach other waste removal or recycling. Another very important thing that should be mentioned about batteries is that they, being made of various materials and technologies, are dangerous for the environment and people’s health in different ways.
That is why different types of batteries are recycled in a different manner.
- Lead-acid batteries like those used in car and other vehicles batteries, UPS batteries, commercial batteries are recycled by the method of grinding via which the lead-acid contained in some form or another within them is neutralized by the separation of the polymers. Even though lead can be recycled, it is advisable that it is kept outside the waste stream because it is highly toxic.
- Silver oxide batteries are another story altogether. Those batteries are the ones we use the most in our everyday life, because they are to be found in watches, toys, and some medical devices, as well as such items like remote controls etc. Silver oxide batteries also contain traces of mercury, which makes them highly toxic. Those batteries can be recycled, and the mercury in them recovered, thus reducing the amount of mercury which is released in the environment.
- Lithium ion batteries are the ones used for powering laptop computers and a number of other high tech electronic devices. Copper, aluminum and some rare earths are all used as components of lithium ion batteries. Those are all very rare and useful materials, and the recycling of those kinds of batteries is high encouraged – because reusing them means saving of lots of resources for the extraction and production of new amounts of the already mentioned metals. Fortunately, lithium ion batteries are probably the easiest for recycling because of their peculiar structure – you just need to know where exactly you are supposed to dispose of them.
When it comes to battery recycling in the United Kingdom the news are not so great. Even though in theory we have good regulations as well as facilities for battery recycling, according to the most recent stats, dating back to 2012, the return percentage of batteries in the UK is just 32%. This is of course better than Canada’s 5.6% but is way below the leaders in the field like Switzerland (73%) and Belgium (71%). According to the latest regulations, all stores that sell more than 32 kg of batteries a year have to offer take back of batteries and arrange for their collection and recycling. Dixons, Currys, The Link and PC World are the main chain stores where you can depose your used batteries. Argos, Homebase, B&Q, Tesco and Sainsbury’s also have battery return boxes and cylinders. Such places for disposal can be found in many smaller retail shops too – just look for the green Be Positive sign somewhere on the walls or windows. Just remember – battery recycling is crucial for keeping the environment safe and sound.
