Meridian Charter Group

A meridian is the line that connects one place to another.

Operating where certainty ends.

Meridian Charter Group is a Lagos-headquartered Nigerian resource-recovery company, with one operational focus: recovering platinum-group metals from spent automotive catalytic converters — milled, blended, assayed, sealed, and exported in traceable lots to European refinery offtake. One operating principle: Arrive prepared. Deliver verified. Build to endure.

Scroll · The Operation
01 The Operation

A single, focused recovery line — feedstock in, sealed lots out.

Spent catalytic converters carry trace platinum-group metals bound to a ceramic honeycomb. We acquire that feedstock through a qualified-supplier network, process the monolith into a uniform powder, prove its grade and moisture in our own laboratory, and ship sealed, documented lots to the refiners who recover the metal.

Input

Spent autocatalysts

Ceramic monolith substrate from end-of-life vehicle catalytic converters, sourced through a multi-node, qualified-aggregator network.

Transform

Homogeneous powder

Decanned, crushed, ball-milled and blended to a single representative grade — then dried to a controlled moisture threshold.

Output

Sealed, assayed lots

FIBC-bagged, XRF-characterised, sample-retained and sealed — each lot exported under documented chain of custody.

02 What We Recover

Three metals. Among the rarest in commerce.

Platinum-group metals are concentrated in autocatalysts precisely because they are scarce and exceptional. Recovering them from end-of-life units returns real value to the supply chain — and keeps it out of landfill.

Pt
Platinum

The benchmark autocatalyst metal — corrosion-resistant, catalytically dense, and central to diesel emissions control.

Pd
Palladium

The workhorse of petrol three-way catalysts. Tight supply has driven recovered material to the front of the market.

Rh
Rhodium

The rarest of the three and the highest-value per gram — reducing nitrogen oxides where the others cannot.

03 Production Flow

Seven stages to a representative lot.

Recovery economics live or die on homogeneity: a lot is only worth what a single sample can prove about the whole. Every stage of the line exists to turn variable feedstock into one uniform, verifiable grade.

01

Decanning

Catalytic converters are opened and the ceramic monolith is separated from the steel casing and packing, isolating the PGM-bearing substrate.

02

Primary crushing

Monolith is reduced to a coarse, free-flowing feed — breaking down the honeycomb structure ahead of fine milling.

03

Ball milling

Crushed material is fine-ground in a ceramic-lined ball mill. Ceramic lining avoids metallic contamination of the powder and protects assay integrity.

Ceramic-lined · ~500 kg batch
04

Vibratory sieving

Milled powder is screened to a controlled particle size. Oversize returns to the mill; on-spec material advances.

05

Blending & homogenisation

The screened batch is blended to a single uniform composition — the step that makes one drawn sample representative of the entire lot.

06

Drying

Powder is dried to a controlled moisture threshold, so that quoted PGM grade reflects dry mass and settlement is clean.

07

FIBC bagging & sealing

The finished lot is weighed into FIBC bulk bags, sampled, sealed and labelled — ready for assay and export under chain of custody.

04 Quality Assurance

An in-house lab line, parallel to production.

A counterparty settles against numbers. The QA lab runs alongside the plant so that no lot leaves without a grade, a moisture figure, and a retained sample to stand behind it.

XRF

PGM characterisation

X-ray fluorescence analysis establishes platinum, palladium and rhodium content on every lot before it ships.

H₂O

Moisture control

A moisture analyser confirms each lot meets threshold, so grade is quoted on a dry basis and settlement is unambiguous.

÷

Representative sampling

A riffle splitter divides the blended powder into true sub-samples — eliminating bias between our assay and the refiner's.

REF

Retained reference

A sealed sample is retained against every lot, giving both sides an auditable reference should any result be questioned.

05 Provenance & Compliance

Documented from kerb to refinery.

Recovered metal is only as good as its paper trail. We are structured so that every lot can be traced, every supplier is known, and every export is documented — by design, not as an afterthought.

Supplier diligence

Known feedstock

Aggregators are qualified and recorded before intake. We know where material comes from and document it at the point of acquisition.

Lot traceability

Sealed chain of custody

Each lot carries its own record — weight, assay, moisture and seal — from blending through to the receiving refiner.

Export discipline

Compliant by design

Structured to satisfy export documentation and counterparty due-diligence requirements on the Nigeria–Europe corridor.

06 Leadership

Founded and operationally led by the people whose names sit against the work.
