A crisis measured in megatons
Electronic waste is the fastest-growing waste stream on Earth. Smartphones, laptops, vapes, earbuds — the average lifespan of consumer electronics has dropped while production volume has climbed. The materials inside them — lithium, cobalt, gold, silver, copper, rare earths — are finite and energy-intensive to mine. When those devices go to landfill, those materials are lost permanently.
Circuit boards, batteries, and displays contain lead, mercury, cadmium, and brominated flame retardants. In uncontrolled landfill conditions these leach into soil and groundwater. Informal “backyard” smelting to recover metals releases carcinogenic fumes — a public health problem concentrated in lower-income communities that receive exported waste.
Harvest before disposal
Industrial recycling infrastructure is centralised, capital-intensive, and inaccessible at the community scale. Our approach is different: intercept discarded electronics before they enter the waste stream and manually disassemble them to recover functional components that can go directly back into use — no smelter required.
Disposable vapes are a particularly concentrated source. Each contains a rechargeable 280–850 mAh lithium-ion cell and a small PCB with a charge controller and sometimes a USB-C port. These components are intact and functional when the device is “dead” — the liquid is simply exhausted.
Over 1 billion single-use vapes are sold annually in the US and UK alone. They are routinely thrown in general waste bins despite containing lithium batteries — a fire hazard in refuse trucks and a source of persistent battery chemicals in landfill. The cells inside are often higher quality than those found in consumer electronics, and they arrive pre-charged.
Dissection in practice
Spencer demonstrates the full disassembly process — cracking the casing, extracting the cell and PCB, testing voltage, and sorting components by condition for reuse or safe disposal.
Recovered components
Each device yields multiple reusable parts. Cells that read above 3.0V under light load are considered serviceable for low-draw applications. PCBs with intact charge controllers can be reused directly in sensor nodes and small battery packs.
Disassembly workflow
Each device takes 3–8 minutes to disassemble depending on case design. No specialised tools beyond pliers, a flathead screwdriver, and a multimeter are required.
-
01
Crack & open
Pry seams with flathead. Snap or cut plastic casing to expose internals.
-
02
Extract cell
Remove li-ion cell. Check leads are intact. Do not puncture or bend.
-
03
Test voltage
Multimeter check. Above 3.0V = serviceable. Below 2.5V = dispose safely.
-
04
Sort & store
Cells into labelled bins by voltage range. PCBs into component trays. Casings into plastic stream.
Never puncture, crush, or short-circuit lithium cells. Work in a ventilated area. Store recovered cells in a fireproof container (LiPo safe bag or metal tin). Dispose of cells below 2.5V at a certified battery recycling point — do not bin them.
What’s inside & why it matters
Beyond the functional reuse of whole components, the raw materials locked in discarded electronics represent enormous embedded energy and finite planetary resources. Mining and refining these materials produces significant emissions and often severe environmental harm at extraction sites.
| Material | Found in | Why it matters |
|---|---|---|
| Lithium | Battery cells | Critical for grid storage and EV batteries. Mining is water-intensive in already-arid regions. |
| Cobalt | Li-ion cathodes | 60% of global supply from DRC, with documented child labour in artisanal mining. |
| Gold | PCB contact pads, connectors | ~0.03g per device. Recoverable by acid stripping at scale; worth ~$1.80/device at spot price. |
| Copper | Wiring, coils, PCB traces | High-value, fully recyclable. Copper mining is one of the largest sources of industrial water pollution. |
| Rare earth elements | Speakers, vibration motors, magnets | Neodymium, dysprosium — virtually no substitutes for high-performance magnets. Near-monopoly supply chain. |
| Tin & lead | Solder joints | Lead-free solder in modern boards. Legacy devices contain lead-tin; handle with gloves, dispose at e-waste facility. |
Reuse whole devices first. Then reuse functional components (cells, PCBs). Then recover raw materials through certified recycling. Landfill is never acceptable — it permanently destroys embedded value and releases toxics with no benefit.
