E-waste and Battery Robots

Why taking things apart is hard to automate

Disassembly is harder to automate than sorting because every item arrives in a different state. A 2025 systematic review in Frontiers in Robotics and AI by Ameur and colleagues, covering 62 studies published between 2000 and 2024, describes the disassembly of waste electrical and electronic equipment as a technical and economic problem, with safety risks that manual methods struggle to meet. Products arrive in many models and conditions, often damaged, with screws, clips and adhesives in different places. The review groups research into four areas: planning the order of disassembly, human-robot collaboration, computer vision and safety. Expect any system you buy to need a person close by for the items it cannot handle.

Batteries add fire and voltage risks

Battery packs raise the stakes. In their 2019 Nature review of recycling lithium-ion batteries from electric vehicles, Harper and colleagues note that packs are currently dismantled by hand, by qualified staff with specialised tools, and they list the hazards: high voltage, short circuits that can lead to thermal runaway, flammable electrolyte and toxic gases such as hydrogen fluoride. They argue that robots could take people out of harm's way and reduce costs, but point out that robots work best with exactly known objects in fixed positions, while battery designs vary widely and lack standardisation. Ask any maker how its cell handles damaged packs, isolates a fire and confirms packs are discharged before work starts.

Treatment rules decide what comes out first

Whatever does the dismantling, EU law sets what must be removed. Article 8(2) of Directive 2012/19/EU on waste electrical and electronic equipment requires proper treatment to include, as a minimum, the removal of all fluids and selective treatment in line with Annex VII. Annex VII lists items to be taken out of separately collected equipment, including batteries and accumulators, printed circuit boards of mobile phones and any other printed circuit board larger than 10 square centimetres, and mercury-containing components. That list makes a useful specification for a robot cell, since it tells you which parts the system must find and extract cleanly, and which must be kept apart for later recovery.

Hybrid cells are the practical first step

For most recyclers, the realistic near-term option is a cell where people and robots share the work. Ameur and colleagues report that combining robotic processing with human capabilities improves disassembly performance, with gains in accuracy and speed, particularly for battery modules and complex automotive components. A sensible split leaves judgement to people, such as assessing damage or freeing seized parts, while robots repeat precise steps such as unscrewing, cutting or sorting removed parts by type. Before investing, sample your incoming stream by product family and condition, find the families that arrive in volume with consistent designs, and trial automation on those first. Keep manual benches for everything else.

Common questions

Can robots recycle lithium-ion batteries safely?

Robots can cut the time people spend near damaged or charged cells, but safety still depends on discharge procedures, fire detection and suppression, ventilation and trained staff. Treat the robot as one control within a wider safety plan, not as the plan itself.

Is there money in recovering parts from old electronics?

Value depends on which materials and components are recovered, how pure they are and current commodity prices, set against labour, energy and treatment costs. Separating circuit boards, batteries and metals cleanly tends to raise the value of each fraction, which is part of the case for careful disassembly.
