Solid recovered fuels — Determination of the recycling index for co-processing

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.

Combustibles solides de récupération — Détermination de l'indice de recyclage pour le cotraitement

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.
