Portable Battery Recycling for Offices & Workplaces: A Complete Guide

Most people wouldn’t think twice about a flat battery going in the bin, yet that small, everyday habit is behind a growing safety problem. In reality, portable batteries are one of the more overlooked risks in an office, both from a fire safety standpoint and from a compliance one and very few workplaces have a proper system in place for dealing with them. Getting battery recycling right starts with understanding why it needs treating differently from general office waste in the first place.

Batteries can’t simply go in with general office waste. Damaged, crushed or improperly disposed of batteries, particularly lithium based ones, are a fire risk, since they can short circuit and ignite when punctured or compressed inside a general waste bin or bag. The National Fire Chiefs Council estimates that more than 1,200 battery fires occur within the UK waste system every year, affecting bin lorries, transfer stations, recycling facilities and treatment plants, a figure that’s risen sharply from around 700 incidents in 2022. That risk alone is reason enough to treat batteries as a separate waste stream with its own collection and handling process rather than an afterthought.

The environmental case is just as pressing. Research from Wastecare’s own Battrecycle initiative estimates that fewer than 15% of portable batteries on the market are currently being collected, against a UK recycling target of 45%. That means collection volumes need to increase by over 300% in the next four years to hit that target, a gap that businesses have a real part to play in closing. Every battery that ends up in general waste instead of a proper recycling stream is a missed opportunity to recover valuable metals rather than losing them to landfill and offices generating even a modest volume of battery waste each year contribute to that gap more than most realise.

Battery waste is covered by its own dedicated legislation rather than falling under general waste rules. The Waste Batteries and Accumulators Regulations 2009 place a legal duty of care on businesses producing battery waste, with exactly what that duty involves in practice set out in the government’s own technical guidance.

For businesses that manufacture, sell or otherwise place batteries onto the market, there’s a further layer of obligation through a Battery Producer Compliance Scheme, which exists to help meet recycling obligations rather than working them out from scratch. This is a separate consideration to the duty of care that applies to any business simply disposing of used batteries and it’s worth checking which category a business falls into, since the two obligations aren’t the same thing and get confused fairly often. Wastecare, as one of the largest collectors and recyclers of batteries in the UK, can pass on third party evidence recognised by the Environment Agency to businesses already in a compliance scheme, or help work out whether an obligation applies in the first place.

Setting up a battery recycling scheme for an office is more straightforward than most businesses expect. Wastecare runs over 30,000 battery collection points nationwide, spanning supermarket chains, large retailers, private companies and the public sector, which gives a good sense of how established this kind of collection infrastructure already is. For a workplace, that usually means a dedicated collection container sized to the volume of battery waste generated, collected on a schedule that fits how quickly it fills up rather than a fixed, arbitrary timetable. Multi-site businesses can run this consistently across every location too, rather than each site working out its own approach independently.

A minimum collection threshold of 40kg typically applies for a standalone battery collection, which most offices of any real size reach without much difficulty once staff have somewhere obvious to put spent batteries rather than a desk drawer. Container sizing and the collection schedule itself sit within the Battery Collection & Recycling for Businesses service and the Portable Battery Recycling service handles what happens to the batteries once they’ve left the building.

One of the more common questions businesses ask before setting up a collection is whether every battery in the building actually qualifies, or only certain types. Wastecare collects and recycles portable batteries nationwide regardless of type or chemistry, which covers the full range typically found in an office rather than a narrow list of accepted formats.

In practice, that means everyday single use batteries like AA, AAA and 9V, rechargeable batteries used in cordless equipment and handheld devices and the lithium-ion batteries built into laptops, phones and tablets are all treated as part of the same collection stream. Button and coin cell batteries, the kind found in small electronics and remote controls, fall under the same scope too, even though they’re easy to overlook precisely because of how small they are. Rather than staff needing to sort or separate battery types before disposal, everything goes into the same collection container, with the sorting itself happening later during processing.

Safe storage is where a lot of workplaces fall short, usually not out of carelessness but because nobody has set out clear guidance for staff to follow. With battery fires in the waste system rising as sharply as they have, getting this step right matters more than it might seem for what looks like a small, low risk item. A few practical points are worth building into any office battery collection scheme:

• Use a purpose built battery collection container rather than a general recycling bin, since batteries need to be kept separate from other waste streams entirely
• Keep damaged, swollen or leaking batteries away from the main collection point and store them individually where possible, since these carry a higher fire risk than batteries in good condition
• Take particular care with lithium batteries from laptops, phones and other devices, since these are more prone to short circuiting than standard alkaline batteries if punctured or crushed
• Avoid storing large volumes of loose batteries together in a single container without any separation, since terminals touching each other can cause a short circuit
• Position collection containers away from direct heat sources and out of direct sunlight, reducing the risk of a stored battery overheating

Getting storage right before collection isn’t complicated, but it does need a deliberate decision rather than being left to chance, particularly in an office where most staff won’t think twice about how a battery ends up in the bin.

Once collected, batteries are transported by licensed vehicle to Wastecare’s recycling facility in Halifax, the first of its kind in the UK dedicated to household and portable battery recycling. There, batteries are shredded and passed through a series of sieves and induced magnetic separators, which work together to identify and separate the different metals inside based on their properties, since different battery chemistries respond differently to this kind of mechanical separation. Anything left over, including carbon, plastic and paper, is pulled out for further recycling in its own right rather than being discarded alongside material that can’t be recovered at all.

Part of what’s recovered during this process is a mixture of valuable metals known as black mass, which is separated out and passed on for future recovery. The recovered materials from the whole process, including metals like nickel, cobalt and lead, are then passed on to appropriate third parties and go on to be used in new products, from stainless steel cutlery and electrical cables through to household white paint. It’s a genuine second life for materials that would otherwise sit in landfill indefinitely, since many of the metals inside a battery don’t break down or lose their value over time, they just need the right process to extract them properly. Every collection also comes with digital Duty of Care paperwork through Wastecare’s myWaste app, so businesses have a fully traceable record of where their battery waste went.

Batteries don’t need to be collected in isolation from a business’s other waste streams. Wastecare can collect batteries alongside WEEE, used cooking oil and fluorescent tubes as part of the same service, which cuts down on the administration of coordinating multiple separate collections for a single site. This matters particularly for offices, where electrical waste and battery waste tend to come from the same source, whether that’s old laptops, phone chargers or the batteries that power them.

Portable battery recycling is one of those things that looks minor on paper but carries a fire risk and a real compliance obligation once a business generates more than a token amount of it. Setting up a proper collection scheme, storing batteries safely in the meantime and working with a licensed provider that can prove where the waste went turns what could be a liability into a straightforward, manageable part of office waste management. With battery fires in the UK waste system continuing to rise and national collection rates still well short of target, the case for getting this right at an office level is only going to get stronger rather than fading into the background.
