This Technical Specification (CEN/TS) was approved by CEN on 24 August 2020 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and

European foreword
This document (CEN/TS 17045:2020) has been prepared by Technical Committee CEN/TC 366
“Materials obtained from End-of-Life Tyres (ELT)”, the secretariat of which is held by UNI.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TS 17045:2017.
The main change compared to the previous edition is the addition of subclause 5.2.5 New puncture
prevention technologies.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the

Introduction
The purpose of this document is to establish general and specific criteria for the use of whole end-of-life
tyres in recycling processes and in material recovery and divide them into different applications, mainly
in the field of civil engineering.
This document does not provide any criteria to select whole tyres to be reused in their original purpose,
i.e. to be mounted on a vehicle. See Figure 1 for an overview of the whole process.

Figure 1 — General scheme of the generation process of end-of-life tyres and their final
processing
The criteria established in this document focus on determining the conditions under which a whole end-
of-life tyre (WELT) can be used for materials recovery and recycling process.
From a legal point of view, in Europe, end-of-life tyres are considered as waste, listed in the European
Waste Catalogue with code 16 01 03, end-of-life tyres.
The criteria for establishing when ELTs cease to be waste could be drafted either by EU legislation, by
the relevant Directives or by any member state.
The purpose of this document is to facilitate the decision making process for establishing the end of the
waste status. This document also aims to overcome the limitations of using WELTs in certain applications
and to clarify the conditions under which they can be intended for recycling or recovery processes in
compliance with technical conditions, ensuring no negative impact to health and environment.
This document aims to increase consumer confidence in the applications of end-of-life tyres and facilitate
the development of the market by the introduction of a specific set of parameters to ensure the quality
and consistency of whole end-of-life tyres to be used for both recycling and recovery applications.
Compliance with the criteria set in this document results in the protection to the human health and the
environment.
WARNING — This document does not purport to address all of the safety concerns, if any, associated
with its use. It is the responsibility of the user of this document to establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior to use.

1 Scope
This document provides criteria for the sorting of whole end-of-life tyres (WELT) into different classes
based on categories. It also provides criteria for the determination of their suitability to be used in
recycling and material recovery processes.
The processes described in this document include sorting WELTs in order to determine their acceptance
in recovery and recycling processes.
Criteria regarding the reuse of tyres to be mounted again in a vehicle are not addressed in this document.
This document does not cover the operational performance of the applications or the requirements of
the materials for certain applications, which are usually agreed between the manufacturer and the
customer.
Solid tyres are excluded from the scope of this document.
