Solid recovered fuels - Determination of the Recycling Index for co-processing (ISO 4349:2024)
This document specifies a method for the determination of the share of material recovery in the case of co-incineration of SRF in a cement kiln. SRF contain inert mineral materials such as SiO2, CaO, etc, which are required for the production of cement clinker. When co-processed in the cement industry, the contained energy is recovered and the mineral part of SRF is incorporated into the clinker. On the basis of the ash content and the ash composition the Recycling-Index can be calculated.
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 SRF u. a. in einem Zementofen fest. Dieser Anteil, der als Recyclingindex bezeichnet wird, 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.

Introduction
When solid recovered fuels (SRFs) 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 are crucial raw materials for cement manufacturers,
fulfil specific tasks in cement clinker production or represent clinker phases giving the clinker its specific
properties. For example, a 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 MgO and TiO , both of which are present
