The language for Connected Commerce

The CircularID™ Protocol establishes the essential product and material data for identification and management of products in the circular economy and ensures this data is accessible and communicated in a consistent way.

Explore the Pilot Version of the Protocol

The CircularID™ Protocol is in Pilot Version, and will launch publicly to industry in 2021 at the completion of the Pilot Period. In collaboration with leading brands and retailers and circular partners, Eon is piloting the CircularID™ Protocol.

Objectives of the Protocol

  • Power circular business models based on selling services instead of products

  • Unlock data and systems essential for maximizing value and recovery of products and materials

  • Bring transparency and accountability to the product lifecycle

Primary functions of the Protocol


Identification of Products

Supporting continued use and circulation of products

CircularID™ Protocol enables the continued identification and monetization of products through circular business models (e.g. rental, resale) and the management of products through channels for continued use and circulation (e.g. repair, reverse-logistics, peer-to-peer, collections, etc.).


Identification of Materials

Supporting continued use and regeneration of materials

CircularID™ Protocol enables the identification of materials for regeneration, including disassembly and recycling.

Structure of the CircularID™ Protocol

The CircularID™ Protocol is structured in two parts: Product ID and Material ID. The structure aligns with the primary functions of the protocol — to facilitate the identification of products and materials. 


Product ID

Brand, Size, Color, Manufacturer Suggested Retail Price, etc.

The Product ID includes all information required to enable commercial identification of the product in order to facilitate the ongoing management, circulation, and monetization of the asset. This information is considered essential for the efficient sorting and reuse of the product to maximize its lifetime utility.


Material ID

Material Content, Dye Process, Thread Type, etc. 

The Material ID includes all information required for the identification of the materials of the product in order to facilitate efficient management of the product’s material components. This information is considered essential for the regeneration of source materials and supports processes such as disassembly and mechanical and chemical recycling.
