Solid recovered fuels - Determination of the Recycling Index for co-processing (ISO 4349:2024)

This document specifies the determination of the share of material recovery in the case of energy recovery (i.e. co-processing) of solid recovered fuels (SRFs), for example, in a cement kiln. This share, called the recycling index (R-index), is calculated on the basis of the ash content and the ash composition.

Feste Sekundärbrennstoffe - Verfahren zur Bestimmung des Recycling-Index für Co-Processing (ISO 4349:2024)

Dieses Dokument legt die Bestimmung des Anteils der stofflichen Verwertung im Falle der energetischen Verwertung (d. h. der gemeinsamen Verarbeitung) von festen Sekundärbrennstoffen (SRF, en: solid recovered fuels) zum Beispiel in einem Zementofen fest. Dieser Anteil, der so genannte Recyclingindex (R-Index), wird auf der Grundlage des Aschegehaltes und der Aschezusammensetzung berechnet.

Combustibles solides de récupération - Détermination de l’indice de recyclage pour le cotraitement (ISO 4349:2024)

Le présent document spécifie la détermination de la part de valorisation de matière dans le cas de la valorisation énergétique (c’est-à-dire le cotraitement) des combustibles solides de récupération (CSR), par exemple, dans un four à ciment. Cette part, appelée indice de recyclage (indice R), est calculée sur la base de la teneur en cendres et de la composition des cendres.

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 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
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).

Introduction
When solid recovered fuels (SRF) are co-processed mainly in the cement industry, simultaneous energy
recovery and recycling of mineral components of waste material takes place because the ash is directly
incorporated into the clinker. SRF co-processing therefore allows for the replacement of both mineral
resources and fossil fuels.
SRF ashes contain various chemical components that either are crucial raw materials for cement
manufacturers, fulfill specific tasks in cement clinker production or represent clinker phases giving
the clinker its specific properties. For example, major part of SRF ashes from mixed municipal and
commercial waste consists of the four main chemical components that are required for cement clinker
production: Al O , CaO, Fe O , and SiO (see Annex A). Additionally, minor ash constituents include
2 3 2 3 2
MgO and TiO , both of which are present in or as clinker phases. K O, Na O are typical constituents of
2 2 2
feldspars that are present in the clay used as a raw material for the process. SO , which is also present in
SRF ash, or another sulfate carrier, is needed in order to convert these alkali oxides into alkali sulfates,
a clinker phase that alters the clinker’s chemical reactivity with water.
