Why Commercial Battery Recycling is Important

Batteries show up in almost every part of a working business, from the handheld scanner on a warehouse floor to the laptop on every desk. Nobody thinks much about them until one stops working and at that point, most just go in the bin without a second thought. What happens after that point is where this gets interesting. This blog looks at why different battery types need different handling, what businesses still gets wrong with battery recycling, and what it actually means for them to get this right.

Not all batteries are made the same way and that’s the starting point for understanding why battery recycling is more complicated than just collecting them in one bin. Alkaline and zinc carbon batteries, the standard single-use type found in remotes and torches, make up a large share of what businesses go through day to day. Lithium batteries power most rechargeable devices and modern electronics. Nickel-cadmium batteries are still common in older power tools and some medical equipment, while lead-acid batteries are typically found in larger equipment and vehicles.

Each of these chemistries needs to be processed differently to recover the materials inside them safely. Wastecare’s specialist facility in Halifax, the first of its kind built in the UK, has the capacity to recycle 100% of the UK’s spent alkaline and zinc carbon batteries and the same site also pre-treats batteries containing lithium, nickel-cadmium, lead and mercury ahead of recovery. Sorting batteries by chemistry as part of waste battery collection is necessary as mixing battery types together during storage and transport increases the risk of a reaction between them, which is one of the reasons properly segregated collection matters so much.

Once batteries reach a recycling facility, they’re sorted by chemistry using a mix of manual and automated systems before being sent for material recovery. Steel, nickel, manganese and lead are among the materials reclaimed from this process and they go back into industries including automotive, construction and electronics manufacturing rather than being lost to landfill.

This recovery matters on two fronts. Mining new raw materials for battery production carries a significant environmental cost of its own, so recovering what’s already in circulation reduces pressure on that supply chain. Batteries left to break down in landfill can also leach hazardous substances such as lead and mercury into the surrounding soil and water over time, which commercial battery recycling prevents by keeping those materials contained and properly processed from the outset.

This is worth being honest about, because it’s a real problem rather than something the industry has already fixed. The UK sets one overall recycling target that covers all types of portable batteries together, rather than separate targets for each type. For years, that combined average has been propped up by lead-acid batteries, which get recycled at a very high rate because the lead inside them is valuable enough to be worth collecting almost every time.

The problem is that lead-acid batteries make up only a small part of what businesses actually use. The batteries people rely on day to day, including alkaline, lithium and rechargeable batteries, were being recycled at a much lower rate, often only around 10%. Because the lead-acid numbers were so strong, they masked just how poorly everything else was being recycled and the UK’s overall figures looked better than the real picture on the ground. Regulators have since taken steps to correct this, but the lesson for businesses hasn’t changed: a good national average doesn’t mean your own batteries are being handled properly. Working with a recycler that handles lithium battery recycling and other chemistries directly, rather than depending on an industry-wide average, is the more reliable way to know your batteries are being processed correctly.

The Waste Batteries and Accumulator Regulations 2009 set out the legal framework that governs how batteries need to be collected and recycled across the UK. Businesses that place more than one tonne of batteries onto the UK market in a year, whether as a manufacturer, importer, or distributor, need to register either with a producer compliance scheme or directly with the Environment Agency. Smaller producers below that threshold still need to register, though the obligations involved are lighter.

For most commercial businesses, the more relevant obligation is simpler: batteries need to be segregated from general waste and sent for proper recycling through a licensed collector rather than thrown away with everything else. Businesses unsure whether they have a producer obligation or simply a collection responsibility can find the full picture of UK battery compliance worth working through before assuming either way.

Beyond the regulatory side, there are straightforward practical reasons to get battery collection right. The most obvious is reduced fire risk on your own premises. Batteries, particularly lithium ones, stored or discarded incorrectly carry a real fire hazard and getting collection and storage right removes that risk before it becomes a problem rather than dealing with the consequences afterwards.

There’s also a cost and admin benefit worth factoring in. Battery collection and recycling services are often available free of charge above a minimum collection volume, which takes the cost barrier out of doing this properly. Some recyclers will pay rebates on batteries with recoverable value too, which can turn what used to be a pure disposal cost into something closer to break-even. For businesses with sustainability commitments to report against, demonstrable, properly documented battery recycling alkaline and lithium collection is also straightforward evidence to point to.

Getting this right comes down to a few consistent habits. Batteries should be sorted by chemistry where possible before storage, with lithium battery terminals insulated to prevent contact with other metal objects. Anything visibly damaged or leaking should never go into a standard collection container and the containers themselves should only ever be used for batteries, not mixed in with other waste streams.

Retailers in particular have found success with dedicated collection points designed specifically for customer use. Morrisons’ revamped portable battery containers are a good example of how a retail-scale collection point can make safe disposal properly easy for customers rather than something tucked away and easily missed. The same principle applies at a national level through the BatteryBack scheme, which has built out a wider network of collection points to increase the volume of batteries recovered safely across the country.

Not every battery a business deals with arrives loose. Laptops, power tools and a wide range of office equipment have batteries built into them and when that equipment reaches the end of its life, the battery needs to be dealt with too. This is where battery recycling overlaps with WEEE collection, since the equipment itself needs treating through the correct WEEE process while the battery inside it is extracted and recycled separately.

Businesses generating a regular stream of old electrical equipment can use free WEEE collection services to deal with both the equipment and any batteries inside it correctly, without needing to dismantle and separate everything manually beforehand.

Commercial battery recycling is about more than ticking a compliance box. Different battery types need different handling, the UK’s recycling figures have historically been skewed by structural imbalances in how lead-acid batteries are counted. Businesses that store and collect batteries properly cut their own fire risk while making sure valuable materials don’t end up in landfill. Get the basics right, sorting by type, storing them safely and using a reliable collection service, the whole thing becomes straightforward rather than something to put off.
