Catalytic converters, recycled and settled on the assay.
Spent converters collected across India from RVSF centres, traders and dismantlers — decanned and assayed here, refined under contract, and paid on what the coating actually holds.

What we do
The value is in the coating, not the shell
A spent catalytic converter is not a lump of metal. It is a ceramic or metallic substrate carrying a thin washcoat, and that coating holds platinum, palladium and rhodium measured in grammes per unit. The shell is worth its weight in stainless steel and no more; everything of value is in the coating. We collect converters across India, decan and process them here, and supply the recovered material to refineries under contract.
Last year we recycled 1,45,006 converters. The stated target for the coming year is to double that. That volume is the reason material other recyclers leave behind — two-wheeler units in particular — is worth processing at all: the fixed cost of decanning, sampling and assay is shared across the lot rather than carried by the unit.
Three metals do the work
Three platinum-group metals do the work in an autocatalyst, and a converter carries some combination of them depending on the engine it was fitted to.
| Metal | Symbol | What it does |
|---|---|---|
| Platinum | Pt | The original autocatalyst metal and still the dominant one in diesel units. Oxidises carbon monoxide and unburnt hydrocarbons, and tolerates sulphur better than palladium does. |
| Palladium | Pd | Took over most petrol applications. It does the same oxidation work as platinum and, for two decades, did it more cheaply. |
| Rhodium | Rh | The scarcest of the three by a wide margin, and the reason a converter can be worth what it is. It reduces nitrogen oxides, and almost nothing else will. |
Which of the three a converter carries, and how much, is what the assay answers. It is also why a price list keyed to the make and model of the car cannot tell you what a unit is worth.
Where does our material come from?
Converters have a theft problem worldwide, so any serious recycler has to be able to say where its material came from. These are our four channels, and each one is a standing arrangement rather than a spot trade.
01
Registered vehicle scrapping facilities
RVSF centres working under the government’s vehicle scrappage framework, where end-of-life vehicles are dismantled against a documented process and every unit can be traced back to a chassis.
02
Converter traders
Established traders who aggregate from workshops and yards and want a buyer who settles on a measured assay instead of a price list keyed to the badge.
03
Vehicle dismantlers
Dismantling yards across Delhi NCR and the wider network, collected on a schedule that suits the yard rather than the truck.
04
OEM production waste
Off-specification and production-waste converters from vehicle manufacturing, handled under the confidentiality that work requires.
What do you actually get from us?
Collection is the easy part. These are the things that decide whether a consignment settles well.
01
The assay is the contract
The substrate is milled to a homogeneous powder and sampled before anyone puts a price on it, so the figure you are paid against is the metal that was actually in the lot. A badge is an assumption. An assay is a measurement, and a measurement can be checked.
02
An umpire you can actually call
Dispute our settlement proposal and an independent laboratory is appointed; its result is the one that settles the lot. It is a small clause that carries the weight of everything else on this page.
03
Certificates that survive an audit
Consignments are handled to the environmental compliance expected under government guidelines, and recycling certificates are issued for the material taken in — which is what an RVSF, a fleet operator or an OEM has to be able to produce later.
04
Washcoat extraction, in-house
Two-wheeler and other low-loading units are processed here rather than turned away. Because the fixed cost of decanning, sampling and assay is spread across a large annual intake, material that is uneconomic elsewhere clears the line with us.
05
Refineries under contract
Recovered material goes to refineries we hold standing contracts with in Europe, Korea and Japan. A contract is the difference between a price schedule you can plan against and hoping a buyer turns up when the lot is ready.
06
Our own trucks, our own paperwork
Collection from anywhere in India and movement onward to the refinery are arranged by us. A correctly classified tax invoice, the e-way bill and the transport documents travel with the consignment, not a week behind it.
How does a lot move from enquiry to settlement?
Tell us what you are holding
Converter type, a rough count and where it is sitting. That is enough for us to say whether it is worth moving and roughly what the settlement would look like.
We collect it
Freight is arranged by us from anywhere in India, on a date that suits your yard rather than a carrier’s route.
Decan, mill, sample, assay
Units are counted in and identified, the substrate is removed and milled to a uniform powder, and a representative sample is assayed for platinum, palladium and rhodium.
Settlement in writing
Payable value is calculated from the assay against the agreed metal prices, less treatment and refining charges, and the proposal comes to you in writing — with an independent umpire available if you do not accept it.
The three steps everything else hangs on
Collection and paperwork are the easy half. These three decide what a lot is worth, and they are the ones worth being slow about.
Questions we get asked before an enquiry
What does Shree Shyam Metals do?
We recycle spent catalytic converters and recover the platinum, palladium and rhodium held in their coating. Units reach us from registered vehicle scrapping facilities, converter traders, dismantling yards and OEM production waste anywhere in India. We decan them, mill the substrate, assay it, and send the recovered material to refineries we hold contracts with in Europe, Korea and Japan.
How is a converter priced?
By measurement, not by model lookup. Two cars off the same production line can carry very different loadings depending on the emission standard they were built to, so a table of makes and models is a guess dressed up as a number. We mill the substrate to a uniform powder, draw a representative sample, assay it, and calculate payable value from that assay against the metal prices agreed for the lot.
What happens if I disagree with your assay?
An independent laboratory is appointed as umpire, and the umpire’s figure settles the lot — ours does not. That is written into the way we trade rather than offered as a favour, because no supplier should have to take a buyer’s word for the number their payment is calculated from.
Do you accept two-wheeler converters?
Yes, and very few recyclers will. A two-wheeler unit holds a small fraction of what a car converter holds, which for years put it below the cost of processing it at all. Our in-house washcoat extraction, and refining partners who will take that output, are what make those units worth collecting.
Will I get a recycling certificate?
Yes, for every consignment we take in, handled to the environmental compliance expected under government guidelines. For an RVSF, a fleet or an OEM, the certificate is usually the part of the transaction that has to survive an audit, so it is issued as a matter of course rather than on request.
Where are you, and will you collect from us?
We work out of New Delhi – 110042, inside the largest logistics hub in Asia, and we run the freight ourselves rather than subcontracting it. Consignments are collected from anywhere in India, and we are registered to export the recovered material to our contracted refineries.
How long does a lot take to settle?
The steps are fixed; the clock depends on the size of the lot. Units are counted in and identified, decanned and milled, sampled and assayed, and the settlement proposal reaches you in writing. We will give you a date when we see the count, and we would rather quote a slow date and hold it than a fast one and miss it.
Holding converters?
Tell us what you have — type, rough count and where it is. We will tell you plainly whether it is worth moving, and what the settlement would look like.
