SUSTAINABILITY

RECYCLING IS THE WHOLE BUSINESS, NOT A SIDE NOTE.

Silverton doesn't mine aluminium — we recycle it. Every ingot we cast starts as scrap: aluminium that's already been used once, in a fan, a car part, an appliance, coming back to us to be melted, filtered, and cast again into an ingot that becomes the next fan or the next car part. That loop is the business.

THE DEEPER LOOK

HOW THE RECYCLING ACTUALLY HAPPENS

Five stages, grouped by what they achieve environmentally — the technical version of the loop shown above.

1

Responsible Sourcing

NO MINING
  • Scrap purchased and assessed by our sourcing experts
  • Manually sorted to remove all non-aluminium material
  • Random sampling confirms quality before it's batched

Every ingot starts as scrap that already existed.

2

Clean, Efficient Melting

BIOMASS FUEL
  • Batch charged into biomass-fired furnaces (~70% of fuel need)
  • Molten metal alloyed and corrected to the target grade
  • Nitrogen + argon degassing removes porosity, refines grain

The single biggest lever in our environmental footprint.

Nothing Goes To Waste

ZERO-WASTE RECOVERY
  • Furnace dross is never discarded as waste
  • Processed through ball mill, pulverizer, magnetic separator
  • Residual aluminium recovered and fed back into production

Most recyclers treat dross as waste. We recover metal from it.

Verified Before It Leaves

NO REJECTED BATCHES
  • Spectrometer tested twice — after melting, again before pouring
  • Corrective material added on the spot if out of range
  • Final ingots randomly re-tested after packaging

Catching errors in-process avoids scrap-worthy failures later.

Ready For The Next Life

CLOSING THE LOOP
  • Cast, embossed, stacked and labeled
  • Delivered to manufacturers who cast fans, auto parts, components
  • Those parts return to us as scrap once their working life ends

This is the sentence that actually explains "circular economy".

COMMUNITY

LOOKING AFTER THE NEIGHBOURHOOD, TOO

We run free medical camps for the communities around our plants, and support Swachh Bharat Abhiyaan cleanliness initiatives locally. Recycling metal and looking after the neighbourhoods around our plants come from the same instinct.
