The thesis

The world has a waste problem it calls an inventory problem. Millions of unsold EVs sit in lots depreciating. Billions of smartphones sit in drawers dead. Landfills swallow batteries, circuit boards, steel chassis, copper wiring, rare earths, and plastics that took colossal energy to create in the first place.

The Urban Mine buys all of it at pennies on the dollar. 5 cents on the dollar for unsold EVs. Bulk acquisition of end-of-life smartphones, laptops, appliances. Everything the world is paying to bury or store, we buy, process, and feed back into the platform as raw material for existing verticals.

This is not recycling. Recycling is a cost centre that loses money and produces downgraded material. The Urban Mine is a profit centre that produces spec-grade feedstock at below-virgin cost, because the energy to process it costs 0.08 cents per kilowatt-hour ($0.0008/kWh).

The logic chain

1
Acquisition at distressed pricing

Buy unsold EVs (dealer overstock, off-lease, damaged, end-of-line) at 5 cents on the dollar. Buy end-of-life consumer electronics in bulk. Buy industrial scrap and e-waste streams that others pay to dispose of. In many cases, the seller pays us to take it (negative acquisition cost).

2
Disassembly and sorting

Automated and semi-automated disassembly lines powered by platform electricity. Every vehicle, phone, or appliance is stripped to component level. Battery packs separated. Motors separated. Chassis separated. Circuit boards separated. Plastics sorted by polymer type.

3
Material stream processing

Each stream goes to the appropriate processing line, all powered by 1-cent electrons:

  • Steel chassis and structural: Shredded, cleaned, fed to Green Steel EAF as curated scrap with provenance locked by SLE
  • Battery cells: Hydrometallurgical recovery of lithium, cobalt, nickel, manganese. Black mass processing into battery-grade precursors
  • Copper wiring and windings: Smelted and refined to Grade A cathode copper
  • Aluminium: Remelted at fraction of virgin smelting energy (recycled Al uses approximately 5% of the energy of primary Al)
  • Rare earths (from motors and electronics): Recovered via solvent extraction. Neodymium, dysprosium, praseodymium returned to magnet-grade purity
  • Plastics: Sorted by polymer (PP, ABS, PA, PE). Clean streams repurposed into eco-blocks for construction. Mixed/contaminated streams undergo pyrolysis into syngas or oils
  • Glass and ceramics: Crushed and graded for concrete aggregate or glass wool insulation feedstock
  • Precious metals (from PCBs): Gold, silver, palladium, platinum recovered via electrolytic refining

Feedstock delivery to platform verticals

Every output stream feeds an existing vertical at cost. Steel to Green Steel. Copper to Green Copper. Plastics to eco-blocks for Housing. Battery precursors to the Molecules platform. Glass to Green Concrete. Nothing goes to landfill. Zero waste by design.

The arithmetic

Order-of-magnitude economics for Year 1. Adjust assumptions as you see fit.

EV stream (unsold and end-of-life)

Acquisition volume100,000 vehicles
Average original MSRP$45,000
Acquisition at 5 cents/$$2,250 per vehicle
Total acquisition cost$225M
Material streamYield/vehicleTotal yieldMarket value
Steel (chassis, frame)~900 kg90,000 t~$54M
Aluminium~250 kg25,000 t~$60M
Copper (wiring, motors)~80 kg8,000 t~$72M
Battery materials (Li, Co, Ni, Mn)~400 kg pack40,000 t packs~$200M+
Rare earths (motors)~2 kg200 t~$20M
Plastics~150 kg15,000 t~$8M (eco-blocks)
Glass~40 kg4,000 t~$1M (aggregate)
EV stream alone: Approximately $415M+ in recovered material value against $225M acquisition cost. Before processing costs (which are dominated by energy at 0.08 cents/kWh).

Electronics stream (smartphones, laptops, appliances)

Acquisition volume50 million devices
Average acquisition cost$0.50 to $2.00 per device (many are free or negative-cost)
Total acquisition cost$25M to $100M
Material streamTotal yieldValue
Copper~5,000 t~$45M
Gold (from PCBs)~1.5 t~$130M
Silver~15 t~$15M
Palladium~0.5 t~$15M
Rare earths~50 t~$5M
Plastics and glass~8,000 t~$4M (eco-blocks/aggregate)
Battery cells (Li-ion)~2,000 t~$10M
Electronics stream: Approximately $224M in recovered value against $25M to $100M acquisition. The gold alone can exceed the total acquisition cost.
Combined Year 1: Approximately $640M+ in recovered material value against $250M to $325M total acquisition cost. Processing energy at 0.08 cents/kWh means the energy cost to disassemble, shred, smelt, refine, and sort 100,000 EVs and 50 million devices is a fraction of what incumbents pay. The margin is structural, not speculative.

Platform interfaces

Inputs from platformupstream

Baseload electricity at 0.08 cents/kWh ($0.0008/kWh) (for shredding, smelting, electrolysis, pyrolysis). Process water from Desalination. Green H2 from Molecules (for hydrometallurgical processing). Logistics infrastructure from Ports vertical.

Outputs to platform verticalsdownstream

Curated steel scrap to Green Steel (provenance-locked, chemistry-windowed). Copper cathode to platform wiring and HVDC. Aluminium to Housing and structural. Battery-grade precursors to Green Molecules. Eco-blocks (recycled plastic construction blocks) to Housing. Glass aggregate to Green Concrete. Rare earth oxides to Turbine and motor manufacturing.

Byproducts and circularityzero waste

Pyrolysis syngas from contaminated plastics feeds Green SNG or is burned for process heat. Slag from smelting goes to Green Concrete. Acid wash residues are neutralised and the metals precipitated for further recovery. Waste heat from smelting and refining cascades to drying, preheating, and adjacent industrial processes. Nothing goes to landfill.

Failure modecascades

If Urban Mine is delayed or shut down: Green Steel loses its curated scrap stream (must rely 100% on DRI, which still works but at reduced throughput). Housing loses eco-block supply. The platform loses a feedstock diversification layer. External: millions of tonnes of toxic e-waste continue to landfill or ship to developing countries for informal processing with severe health consequences.

What the Urban Mine eliminates

Governance

This is an example

The Urban Mine is shown here to demonstrate the level of rigour required. Your submission must cover the same ground: thesis, logic chain, arithmetic, platform interfaces, failure modes, circularity, governance.

You do not need to submit an Urban Mine. You need to submit something as good as the Urban Mine. Or better.
