The recycling guide: from bin to ingot, end to end
The Scrap Guide covers the seller's side of the trade. This hub covers the wider story: how metal recycling actually flows from bin to ingot, what's different about auto recycling and e-waste, and why construction and demolition has its own logistics universe. Each category below is a different recycling stream — pick the one that matches your material.
What this hub covers
Most "recycling" content treats every stream identically. They're not. A copper pipe and a circuit board are both technically e-waste-adjacent, but they enter completely different supply chains. Sub-topics:
- The physical process of metal recycling — collect, sort, shred, melt, cast, roll
- Why metal recycling pays (mass recovery rate above 90%) while plastic recycling mostly doesn't
- Auto recycling, including the catalytic-converter sub-economy
- E-waste recycling and precious-metal recovery from boards and harnesses
- Construction and demolition — rebar, structural steel, HVAC reclaim, concrete-bonded metal
Streams in the recycling silo
| Category | What it covers | Best for |
|---|---|---|
| Metal Recycling | Steel, aluminum, copper, brass — the core streams | Sellers wanting end-to-end context |
| Auto Recycling | End-of-life vehicles, cats, body shells | Anyone scrapping cars |
| E-Waste Recycling | Boards, wire harvest, precious metals | Tech recyclers, IT decom |
| Construction & Demolition | Rebar, structural steel, HVAC reclaim | Contractors, demo crews |

Frequently asked questions
Is metal recycling actually profitable, or is it just marketing?
Profitable. North American mills source 65–70% of their feedstock from recycled scrap because remelting is dramatically cheaper than refining ore. The full economic picture is on Metal Recycling.
Where does my scrap actually end up?
Yard, then a regional processor (shredder or shear), then a mill (EAF for steel, secondary smelter for non-ferrous), then ingot or coil, then a fabricator. The Metal Recycling category traces this end-to-end.
What can't be recycled?
Most metal can be — but lithium batteries, mercury switches, sealed refrigerant systems, and PCB-contaminated transformers all need specialized handling. Cars get their own chain (see Auto Recycling), boards get theirs (see E-Waste Recycling).
