dismantling (manual dismantling)

Dismantling is the first value-adding step in an authorised e-waste recycling line after collection and weighing. It is the controlled disassembly of whole appliances and devices — desktops, laptops, CRT and LCD monitors, printers, ACs, washing machines, mobile phones — into homogeneous fractions: printed circuit boards (PCBs), cables and wiring harnesses, ferrous and non-ferrous metal casings, engineering plastics, glass, batteries, capacitors, LCD backlights and CFL/CCFL mercury lamps. Under the E-Waste (Management) Rules 2022, dismantling is a separately defined activity and a dismantler must hold CPCB/SPCB registration on the EPR portal distinct from a recycler registration, though many facilities hold both.

In the Indian context dismantling is overwhelmingly manual, using screwdrivers, pliers, pneumatic drivers, hammers and hot-air guns, because labour at Rs 400–700 per day is cheaper than automated shredding lines costing Rs 1–3 crore and because manual teardown preserves higher-value intact components (working RAM, hard drives, processors, reusable power supplies) that pure shredding destroys. A trained worker dismantles roughly 40–80 kg of mixed e-waste per shift depending on device mix. The critical discipline is de-pollution first: batteries, mercury lamps, CRT cones, toner cartridges and capacitors must be removed and segregated before any crushing, because a single ruptured lithium cell or CRT funnel contaminates the whole batch and triggers a fire or lead-dust hazard.

The output of dismantling is not finished product but concentrated, sorted fractions that feed the next stage. PCBs go to recyclers or smelters for precious-metal recovery; clean copper wire is sold to non-ferrous refiners; steel and aluminium casings go to ferrous/non-ferrous scrap dealers; mixed plastics go to mechanical recyclers or are sent for energy recovery; hazardous fractions (CRT lead glass, mercury lamps, batteries) go to authorised treatment, storage and disposal facilities (TSDFs). Good dismantling raises downstream recovery yield and value; poor dismantling that mixes streams (copper-aluminium cable, ABS-PC plastics) destroys grade and price.

For an Indian recycler, the operational reality is that dismantling is where margin is made or lost. Worker safety matters — cut gloves, dust masks for toner and CRT work, no open burning of cables to recover copper (illegal under the Rules and a dioxin hazard; mechanical stripping or granulation is mandated instead). Record-keeping matters — inbound and outbound weights per fraction must reconcile in the EPR portal returns, so a dismantling bench should weigh and log fractions per batch. The single most common compliance failure in audits is unaccounted weight loss between e-waste received and fractions sold, which auditors read as informal-sector leakage.
