Recycling & Waste Management

When collecting and sorting used batteries, the actual condition of individual cells is often unknown — a particularly high-risk environment for thermal runaway.

Starting point

The starting situation in this area

RUK Li-Ion Safety Box – example placement in Recycling & Waste Management

Instead of open collection bins, an enclosed, monitored space makes it possible to safely store conspicuous or damaged batteries temporarily before they are processed further.

In collection and sorting, the condition of the batteries is not just unknown. It is expected to be poor. What arrives has been discarded, is defective, mechanically damaged, deeply discharged or swollen. Otherwise it would not be there.

Deliveries are mixed: different cell chemistries, formats and manufacturers, often with no marking and frequently in open collection containers. Checking each one is not feasible at these volumes, and damaged cells are not always obvious at once.

Then the surroundings: sorting plants, conveyors, presses and large amounts of combustible material. Between intake and onward processing there is always intermediate storage — and that is where most incidents start.

Locations

Where the fire protection box is used in practice

01Collection and sorting areas for used batteries and e-waste
02Interim storage for damaged or unknown batteries
03Collection points for consumer and commercial used batteries
04Workshop areas for inspecting incoming devices

How it works

How it works in practice

01
Separate batteries that look wrong
Batteries with visible damage or an unclear condition are taken out of the stock before they go into bulk storage.
02
Store them safely in between
Instead of an open collection bin, the box offers a closed, monitored place for individual risk cases.
03
Watch the condition
Temperature sensors continuously watch the stored batteries for signs of a critical state.
04
Pass them on under control
Only after an unremarkable check do the batteries go on into the regular sorting and recycling chain.

Benefits

What the deployment achieves in practice

Designed for unknown condition

Reduces the elevated risk from often damaged or unclearly classified used batteries.

Safe interim storage

Replaces open collection bins with an enclosed, monitored storage space for individual cases.

Protects employees

Reduces risks for staff in intake and sorting logistics.

Supports due diligence obligations

Contributes to traceable, careful handling of used batteries.

In detail

Typical situation, risk and solution

Typical situation	Risk without protection	With the RUK Li-Ion Safety Box
Collection of used and damaged batteries of unknown condition	Damaged cells carry an increased risk of thermal runaway	Separate, monitored storage of conspicuous individual batteries
Open collection bins in sorting areas	A single defect can spread to the entire collected stock	Enclosed system limits the spread to individual batteries
High throughput of third-party devices of unclear origin	The condition of batteries is often unknown on arrival	Safe testing and interim storage point before further processing
Employees in direct contact with used batteries	Increased risk during manual sorting	Reduced risk through a defined safety zone
Large amounts of e-waste arriving from different sources	Single damaged cells are hard to spot in big collected batches	A separate check place for conspicuous individual batteries before they go into collection containers
Legal duties of care when handling waste batteries	A duty to account to authorities and clients if there is an incident	Traceable, documentable handling of critical individual cases
