We manage the secure collection and transport of gold and silver byproducts from factories and industrial units to refineries for metal recovery
Understanding Industrial Byproduct Logistics
Modern manufacturing uses gold and silver in quantities small enough to be invisible in any one component — a few micrograms in a semiconductor bond wire, a thin layer of silver in a solar cell contact, a plating deposit on a medical device connector. Multiplied across millions of units and months of production, those invisible quantities add up to kilograms of recoverable metal sitting in industrial scrap, dust, sludges, and reject parts. Moving that material from the factory floor to a refinery is a logistics discipline in its own right.
Industrial byproducts are not like jewellery scrap. The metal is locked inside other materials — silicon wafers, ceramic substrates, polymer boards, plating sludge, spent electrolyte. Weights at the factory reflect the full material, not the recoverable metal content, which only becomes clear after the refinery's assay. This creates a specific logistics demand: every gram of material that leaves the factory must be the same gram of material the refinery weighs in — because the refinery's assay on that material determines the client's recovery payment.
The material itself is often difficult to handle. Fine dust from grinding and polishing can disperse if not sealed correctly. Plating sludges and spent solutions are liquids or semi-solids that need leak-proof containment. Mixed-form scrap — reject boards plus polishing residue plus anode remnants — needs separate packaging and documentation so the refinery can treat each stream correctly. A generic high-value courier is not built for any of this. Industrial byproduct logistics is a precious metals problem, a hazardous-form problem, and a compliance documentation problem at the same time.
"For an industrial user, the refinery's assay report is the moment of truth. Everything the logistics partner does — from weighing the first drum at the factory to sealing the last packet at dispatch — is about making sure that report is clean."
At BVC, we manage industrial byproduct recovery logistics as a specialist flow. Collection from the factory floor with specialised handling for dust, scrap, liquids, and mixed materials. Packaging designed for each byproduct form. Secure, monitored transport to licensed refineries across India. Chain-of-custody documentation that supports the refinery's assay, the client's GST position, and internal audit. Where needed, secure vault holding before refinery dispatch or after recovery. End-to-end — from the production line to the recovered bullion.

Approach Comparison
Industrial byproduct movement is often treated as a waste disposal problem, not a precious metals logistics problem. Here is what typically goes wrong — and what BVC does instead.
An electronics manufacturer generates three byproduct streams — fine grinding dust, reject PCB boards, and plating sludge. A general industrial transporter packs all three into the same consignment using standard cardboard drums. Dust mixes with sludge. The refinery receives a contaminated lot and has to run additional pre-treatment before assay — delaying recovery and reducing yield.
BVC uses material-specific packaging for each byproduct stream — sealed dust-containing drums for fine residues and rigid containment for reject boards.
A plating unit dispatches 80 litres of precious-metal-bearing spent electrolyte in a second-hand chemical drum. The drum's seal is not leak-proof under road vibration. Several litres leak in transit. The refinery receives a partial quantity — and the lost volume carried silver that cannot be recovered.
BVC uses leak-proof, tamper-evident containment designed for precious-metal-bearing remains. Packages are sealed and validated for road transport. What leaves the factory is what the refinery opens — no in-transit loss.
A manufacturer's byproduct batch reaches the refinery with only a generic delivery note. The refinery requires per-stream records — material type, estimated quantity, source process, factory weight, and transport chain-of-custody — before it assays and settles. The consignment waits in the refinery's queue for days while the client reconstructs the paperwork.
Every byproduct consignment is dispatched with complete documentation the refinery expects: per-stream records, source process reference, factory weights, transit custody log, and unique consignment IDs. Refinery assay and settlement proceed without paperwork delays.
A manufacturer treats byproduct dispatch as industrial waste movement — standard truck, no GPS tracking, no secure handling protocol. On inspection, the recoverable metal content of the batch runs into several kilograms of silver equivalent. The insurance cover the manufacturer has on the consignment is a generic goods policy that does not reflect the actual metal value. A loss event would not be covered at recovery value.
BVC transports industrial byproducts with the security posture the recoverable metal content demands — GPS-tracked vehicles, controlled routes, control room monitoring, and insurance valued at the declared value of metal content. The security and cover align with what is really in the drum.
How It Works
Click each step to understand what BVC does at that stage of the industrial byproduct recovery flow.
BVC collects gold and silver byproducts directly from the industrial site — production scrap, reject parts, polishing dust, grinding residue, plating sludge, spent electrolyte, filter cake, anode remnants, and other precious-metal-bearing material. Pickup is scheduled around the client's production and accumulation cycle.
At pickup, material is accepted by stream — dust separate from reject boards, sludges separate from solids — so that each stream can be packaged, documented, and routed correctly through to refinery intake.

What Planning Covers
What BVC Brings
Understand what each capability means for manufacturers and industrial units recovering gold and silver from production byproducts.
01.
Safe transport of dust, scrap, liquids, and mixed materials.
BVC's purpose-built protocols cover every byproduct form — fine dust and grinding residue, reject parts and solid scrap, plating sludges and spent electrolyte, mixed-purity material. Containment is selected per stream so the form of the byproduct does not compromise the quantity that reaches the refinery.
02.
From industrial site to refinery and beyond.
From factory gate pickup through transit, refinery delivery, and optional bullion return, BVC manages the complete byproduct recovery flow. One partner handles every link — so the client is not coordinating three providers and hoping the paperwork matches up at each handover.
03.
Every consignment, every stream — visible in real time.
Complete shipment tracking at every stage through BVC's portal — pickup, in transit, refinery intake, assay status, and (where applicable) bullion return. Client operations and finance teams see the same real-time view, without chasing updates over email.
Indian Regulatory Context
Byproduct movement sits at the intersection of precious metals rules, GST, and — for certain streams — hazardous and e-waste handling regulation. Getting the logistics documentation right is what keeps the client's tax, audit, and environmental compliance position clean.
Movement of precious-metal-bearing scrap and byproducts to a refinery is a taxable supply under GST. The valuation is benchmarked to IBJA rates for the estimated metal content. BVC's documentation formats support the client's GST invoicing and input tax credit position on byproduct dispatch and bullion return.
Inter-state movement of byproducts above Rs. 50,000 requires an e-way bill. Several states have notified intra-state e-way bill requirements for precious metals above Rs. 2 lakh under CGST Rule 138F. BVC generates the correct e-way bill for every byproduct movement where the thresholds are met.
PCBs, semiconductor assemblies, and electronic reject components can fall within the E-Waste (Management) Rules, 2022 when classified as e-waste. Transport documentation must reflect the correct regulatory classification where applicable. BVC structures documentation to work alongside the client's EPR and authorised recycler obligations.
Certain byproduct streams — plating sludges, spent electrolytes, filter cakes — can be classified as hazardous waste under the Hazardous and Other Wastes Rules, 2016, requiring authorised handling and documentation. BVC's packaging and documentation align with this framework where applicable, without compromising the precious metals logistics layer.
Licensed Indian refineries, including LBMA-accredited facilities like MMTC-PAMP, accept byproduct material only with complete supplier and transport documentation — supplier identity, source process, per-stream records, and chain-of-custody. BVC's documentation meets refinery intake expectations on the first pass, keeping assay and settlement cycles on track.
India Bullion and Jewellers Association (IBJA) gold and silver rates are the standard benchmark for byproduct valuation, insurance coverage, and refinery settlement in India. Every BVC byproduct consignment is insured and invoiced at the day's IBJA rate applied to the estimated recoverable metal content — aligning documentation, insurance, and settlement values.
