Total Equipment Capex by Plant Type
Master capex reference for four e-waste recycling plant types — mechanical, PCB, pyrometallurgical, and hydrometallurgical — showing required equipment, indicative total machinery investment, skill profile, and ideal operator profile for each plant type.
| Plant Type | Required Equipment | Total Capex Range | Skill Profile | Best For |
|---|---|---|---|---|
| Mechanical Recycling Plant | 5–10 conveyors + Single & Dual Shredder + Hammer Mill + Magnetic Belt + Magnetic Drum + Eddy Current + Vibratory Table + Cyclone + Air Classifier + Dust Collection (Cyclone + Baghouse + HEPA) + Optical Plastic Sorter | ₹2–4 cr (3 TPD) | Manual operators + machine operators; no chemistry team | First-time entrants, small/medium operators |
| PCB Recycling Plant | Depopulator + PCB Component Crusher + PCB Shredder + Magnetic Drum + Pulverizer (Fine Mill) + Sieve Screens + Air/Gravity Separator + Electrostatic Separator + Dust Collection | ₹1–2 cr basic / ₹3–5 cr full setup | PCB-machinery operators (often co-located with hydro team) | Existing mechanical plants adding precious-metal capture |
| Pyrometallurgical Recycling Plant | Electric Arc Furnace (30–80 MW) + Reverberatory/Rotary Furnace + Induction Furnace + Blast Furnace + Ladle Furnace + Refining Equipment + Gas Treatment + Slag Handling + Continuous Casting | ₹5–8 cr basic non-ferrous / ₹10–15 cr full setup | Skilled metallurgists + furnace operators + gas-treatment engineers | Scaled mechanical operators with steady ferrous + non-ferrous output |
| Hydrometallurgical Recycling Plant | Acid Wash Tanks + Electrolytic Cells + Aqua Regia Reactor + Precipitation Tanks + Fume Scrubbers + Refining Furnaces (Au/Pd/Pt) + Chemical PPE Infrastructure + Acid-Resistant Flooring + Assay Lab | ₹10–15 cr Cu/Ag-only / ₹20–25 cr full Cu/Ag/Au/Pd/Pt | Hydrometallurgy chemistry team + lab-grade safety culture (highest skill bar) | Scaled operators with own mechanical + PCB plants |

How to read this table
- Each row is one plant type; columns show the required equipment list, indicative total machinery capex, skill profile, and best-fit operator profile.
- Capex figures are for equipment only — civil works, utilities, environmental control systems, and working capital add substantially to the total project investment.
- Plant types are typically built sequentially: mechanical first, then PCB, then either pyro or hydro depending on the operator's capital position and skill base.
About this table
Selecting a plant type is the most capital-consequential decision in an e-waste recycling business. The four plant types differ not just in equipment cost but in the skill profile required to operate them, the feedstock they need, and the buyer relationship they generate. This table is the master reference for comparing all four options — from the lowest-cost, lowest-complexity mechanical plant to the highest-cost, highest-margin hydrometallurgical plant.
The Mechanical Recycling Plant is the standard first-plant choice for new e-waste operators. It processes mixed e-waste through shredding, magnetic separation, eddy-current separation, vibratory density tables, and dust collection to recover ferrous metals, non-ferrous metals, and plastics. The equipment list includes 5–10 conveyors, a shredder line, hammer mill, magnetic and eddy-current separators, air classifiers, and a three-stage dust collection cascade. No chemistry knowledge is needed — the operation is fully mechanical and can be run by operators trained on equipment maintenance. The PCB Recycling Plant focuses on printed circuit boards — the highest-value fraction in e-waste by precious metal density. It uses a depopulator, PCB crusher, shredder, and a series of physical separation stages. The basic setup processes PCBs to the crushed component fraction stage; the full setup adds electrostatic and gravity separation.
The Pyrometallurgical Plant is the highest-infrastructure plant type — Electric Arc Furnaces, reverberatory and rotary furnaces, induction furnaces, and continuous casting equipment require a skilled metallurgical team and major civil infrastructure (30–80 MW power connection for EAF operation). The Hydrometallurgical Plant is the terminal precious-metal refining stage — using acid wash tanks, aqua regia reactors, electrolytic cells, and precipitation tanks to isolate gold, silver, palladium, platinum, and copper at 99.9% purity. It requires a chemistry team with hydrometallurgical expertise and acid-handling safety protocols.
Plant types are typically built sequentially: mechanical first, then PCB, then pyrometallurgical or hydrometallurgical depending on the operator's capital position, available power supply, and in-house chemistry capability.
Key insights
- Mechanical recycling is the recommended first plant for a new e-waste operator — it has the lowest equipment capex of the four types, requires no chemistry team, and generates five distinct output streams covering all major metal and plastic categories.
- Pyrometallurgical plants require 30–80 MW power connections for Electric Arc Furnace operation — this power infrastructure requirement limits viable locations to industrial areas with guaranteed heavy-power supply.
- Hydrometallurgical plants process small volumes at high value — 50–500 kg/day of precious-metal concentrate generates significant revenue because gold and palladium at 99.9% purity are priced at bullion rates.
- PCB plants are constrained by PCB feedstock availability, not equipment capacity — most operate below nameplate because high-grade PCB e-waste volumes through normal aggregator channels are limited.
Methodology & sources
Equipment lists and total capex ranges are based on industry reference data as described in course materials as of 2024. Civil works, utilities, environmental control systems, and commissioning costs add 25–40% on top of equipment costs.
