Shredder Process

Automotive shredder residue is a direct output of how modern shredding works. An end-of-life vehicle is fed into a hammermill that reduces it to fist-sized fragments, which then pass through a chain of separation stages designed to pull out the valuable metals — leaving the mixed remainder as ASR.

The sequence runs from magnetic separation for steel, through eddy-current and other techniques for non-ferrous metals, down to ever-finer recovery of copper, aluminium and stainless steel. Each stage extracts a commodity; each one also leaves behind a progressively harder-to-sort residue.

What the Shredder Leaves Behind

By the time the metals are recovered, what remains is the composite the car was ultimately built from: plastics, rubber, glass, foam, textiles and the mineral fillers. This is the shredder residue — and it is generated at a rate that tracks directly with how many vehicles and appliances are retired each year.

Klean’s reference plant receives residue from five shredder plants feeding cars and white goods, plus two non-ferrous separation facilities, and the post-shredder particle size already matches the gasifier’s feed specification — meaning the residue can be processed with no additional pre-treatment.

The Residue Is Where the Remaining Value Lives

The shredder is optimised for metals, not for the residue it produces. That residue still holds fuel energy, trapped metals and minerals — value that is lost when the stream is simply sent to landfill, and recovered when it is routed to the right thermal process.

Partner With The KleanTeam to Process What the Shredder Leaves

Safe. Clean. Profitable. One Proven Partner.

Klean Industries works with shredder operators to turn their ASR output from a disposal cost into a secondary revenue stream, applying gasification that accepts the residue as-is and recovers what the shredder could not.

Klean’s Key Advantages:

• ✅ An operating ASR gasification reference plant fed by five shredder plants.
• ✅ Thirty-plus years engineering commercial gasification and waste-to-energy plants.
• ✅ 3 recovered carbon black (rCB) plants built in India over the past 2 years.
• ✅ KleanLoop blockchain provides end-to-end feedstock traceability.
