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.
