ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

different types of ISO documents should be noted. This document was drafted in accordance with the

Rare earth elements (REEs) have become essential constituents for wide range of industrial applications

including electric vehicles, batteries, smartphones, displays, transparent lenses, optical fibre and

numerous other applications. Due to these various but important applications, REEs are called as

“Vitamins of Industry”. In order to ensure the successful use of these vitamins of industry, supply to

the industry should be smooth. But resource scarcity creates imbalance between supply and demand.

Therefore, the importance of REEs is getting even more and more. In order to overcome this constraint

of resource scarcity, recycling or urban mining of industrial waste and end of life cycle products is

For recyclers, it is of utmost importance to know what kind of REEs are present in the waste or scrap

material, and how much can be extracted. Hence, in order to facilitate recycling it is important to define

what information is required by recycler, and it is also necessary to establish a standard for methods of

Due to the lack of a standardized system and communication exchange mechanism between waste

handlers and recyclers, the recycling ability still lags behind of what it should be. There are many

producers of the same product but the compositions and concentrations are differernt, and that makes

it difficult and complicated for the recyclers to obtain exact information about the elements being

recycled. Furthermore, if producer and recycler is placed in different countries then information

reliability and cross-border transaction of information exchange is problematic. Therefore, a system of

This standard contains a system of information exchange between waste handlers and recyclers about

REEs in industrial waste (Industrial waste generates from downstream processing operations of the

manufacturing industries) and end of life products. System of information exchange refers to a data

exchange mechanism such as and quick response (QR) code and radio frequency identification (RFID).

This standard provides the methods of information exchange between waste handlers (of industrial

wastes and end of life products) and recyclers of rare earth elements (REEs) about REEs contained

in industrial wastes and end of life products. The purpose is to facilitate recyclers for efficient REE

recycling for management of REE resources. The document also includes a generic life cycle of REE
