Foreword
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 non­governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

Introduction
Rare earth elements (REEs) have become essential for a wide range of industrial applications including
electric vehicles, batteries, smartphones, displays, transparent lenses, optical fibre and so on. Due to
these varied, important applications, REEs are referred to as “vitamins of industry”. In order to ensure
the successful use of these vitamins, supply to the industry should be smooth. However, resource
scarcity creates an imbalance between supply and demand. Therefore, the importance of REEs
is increasingly significant. In order to overcome resource scarcity, the recycling or urban mining of
industrial waste and end-of-life (EOL) cycle products is necessary.
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. In order to facilitate recycling, it is important to define what
information is required by the recycler, and to establish a standard method of information exchange on
REEs in industrial waste and EOL products.
Due to the lack of a standardized system and communication exchange mechanism between waste
handlers and recyclers, the ability to recycle currently lags behind what it should be. There are
many producers of the same product, but compositions and concentrations are different, which
makes it difficult and complicated for recyclers to obtain exact information about the elements being
recycled. Furthermore, if the producer and the recycler are located in different countries, information
reliability and cross-border transaction of information exchange is problematic. Therefore, a system of
information exchange between the waste handler and the recycler is needed.
This document contains a system of information exchange between waste handlers and recyclers
about REEs in industrial waste and EOL products. The system of information exchange involves a data
exchange mechanism such as quick response (QR) codes and radio frequency identification (RFID).

Exchange of information on rare earth elements in
industrial wastes and end-of-life cycled products
1 Scope
This document specifies methods of information exchange between waste handlers and recyclers for
rare earth elements (REEs) contained in industrial waste and end­of­life (EOL) products. This document
facilitates the efficient recycling of REEs so that dependency on mining can be reduced by promotion of
REE recycling.
