Pilot 003 - Hardware Bill of Materials

Sponsor: RMI  |  Phase: 1  |  Date: July 2025


Evolving Knowledge Base

The RBTP Knowledge Base is evolving weekly as part of our pilot programs with RBA members. We’d love your input — submit feedback or help shape the protocol in real time by joining a pilot.

1. Overview

Phase 1 of Pilot 003 demonstrated a 2-tier supply chain with multiple components being assembled to make a laptop.

Key Question:

How can RBTP help organize and understand components that make up an assembly (HBOM) and provide traceability for products that are assembled and/or aggregated?

Answer:

A Digital Traceability Event (Assemble/Association) connects 4 Product Passports (battery, a screen, a keyboard and a case) to a single DPP of a laptop.

4. Scope & Supply-Chain Actors

For this Phase 1 pilot, we defined a representative chain of several actor types and generated synthetic credentials for each:

  1. Battery manufacturer (Battery assembly; Synthetic Facility)
  2. Laptop screen manufacturer (Component assembly; Synthetic Facility)
  3. Laptop keyboard manufacturer (Component assembly; Synthetic Facility)
  4. Laptop case manufacturer (Component assembly; Synthetic Facility)
  5. OEM (Electronic-goods assembly; Synthetic Facility)
  6. Recycler (End-of-life goods → refinery feed; Synthetic Facility)

5. Phase 2 and Beyond
