Material Provenance
Every material recovered by ML Systems gets a unique ML Material ID and a full provenance chain. Look up any material to see its journey from source building to marketplace.
Enter a full ML Material ID (e.g., ML-2026-001-R042) or scan the QR code on the material tag.
How Provenance Works
Identification
Material is identified during deconstruction assessment. Species, dimensions, and condition are recorded.
Recovery & Testing
Material is carefully extracted, tested for contamination (lead, asbestos, mold), and graded A through Salvage.
ML Material ID
Unique ID assigned: ML-{year}-{project}-{zone+seq}. QR code generated linking to this public provenance page.
Chain of Custody
Every event logged: identified → tested → recovered → graded → photographed → listed → sold → DEM reported.
ML Material ID Format
ML (ML Systems)
Recovery year
Source project number
R=Roof, W=Walls, F=Floors, N=Foundation, K=Kitchen, H=Hardware, D=Doors/Windows, S=Sheathing, E=Electrical, P=Plumbing, X=Other
Material Grading
Excellent
Like new, minimal wear
Good
Minor cosmetic wear
Fair
Visible wear, structurally sound
Below Average
Significant wear, limited use
Salvage
Raw material value only
Contamination Status
Provenance data available via API: GET /api/v1/materials/provenance/{mlId} — no authentication required.
DEM export (CSV/JSON-LD) available for authenticated partners.
