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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at

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
