CEN/TS 15359:2006 (E)
Introduction
The objective of this Technical Specification is to provide unambiguous and clear classification and
specification principles for Solid Recovered Fuels (SRFs). The Technical Specification aims at serving
as a tool to enable efficient trading of SRFs, promoting their acceptability on the fuel market and
increasing the public trust. The Technical Specification will facilitate a good understanding between
seller and buyer, facilitate purchase, transborder movements, use and supervision as well as a good
communication with equipment manufacturers. It will also facilitate authority permission procedures
and ease the reporting on the use of fuels from renewable energy sources and on other environmental
issues.
)
1
SRFs are produced from non hazardous waste. The input waste can be production specific waste,
municipal solid waste, industrial waste, commercial waste, construction and demolition waste, sewage
sludge etc. It is thus obvious that SRFs are a heterogeneous group of fuels. A well defined system for
classification and specification is therefore of great importance to reach the above mentioned
objectives and intentions.
This Technical Specification covers all types of SRFs and will thus have a wide field of application. It
supports the objectives and implementation of the EU waste hierarchy as defined in article 3.1 of the
waste framework directive 75/442 modified by the directive 91/156.
This Technical Specification describes the compliance rules which a SRF has to meet to be classified
according to the classification system. It also describes how the supplier can establish a declaration of
conformity to the different Technical Specifications for SRFs (see Clause 2).
Figure 1 illustrates a simplified flow chain for SRFs, from input of waste to end use of SRFs. This
Technical Specification has an interface to all the stages in the chain, but SRF classification and
specification are applicable at the point of delivery as shown in the figure. Requirements for how the
input waste is collected and how to use the fuel are not part of this Technical Specification.

Hazardous waste is defined in the Directive on hazardous waste (91/689/EEC) and its amendments, and are
elucidated and exemplified in the waste list ((Commission decision 2000/532) and its amendments, in particular
2001/118/EC).

5 Principles
The classification system is based on three important parameters, referred to the main SRFs
properties: an economical parameter (net calorific value), a technical parameter (chlorine content) and
an environmental parameter (mercury content). The parameters are chosen to give a stakeholder an
immediate but simplified picture of the fuel in question.
Only fuels derived from non hazardous waste that meet the SRFs standards can be classified as
SRFs.
The classification itself is not enough for an intending user. A user has to have a more detailed
description of the fuel. Relevant fuel properties are thus to be further specified. Some of the fuel
properties are so important that they are obligatory to specify whereas others can be recorded
voluntarily, e.g. upon request of the user.
It is important that SRFs meet specified quality requirements which are to be determined on a defined
lot size by a minimum number of measurements.
6 Requirements and declaration of conformity
In conformity with this Technical Specification, SRFs shall comply with the following requirements:
a) SRF shall be classified according to the system in Clause 7.
b) SRF shall meet quality requirements according to given compliance rules in Clause 8.
c) SRF properties shall be specified according to Clause 9.
The producer/supplier shall give a declaration of conformity to this Technical Specification. The record
shall be kept available for inspection. A model template for the declaration is given in Annex C.
NOTE General criteria for a supplier’s declaration is given in EN ISO/IEC 17050-1:2004 and EN ISO/IEC
17050-2:2004.

CEN/TS 15359:2006 (E)
7 Classification
The classification system (Table 1) for SRFs is based on limit values for three important fuel properties.
These are:
a) the mean value for net calorific value (ar);
b) the mean value for chlorine content (d);
th
c) the median and 80 percentile values for mercury content (ar).
Each property is divided into 5 classes with limit values. The SRF shall be assigned a class number
from 1 to 5 for each property. A combination of the class numbers makes up the class code (see
example below). The parameters are of equal importance and thus no single class number determines
the code.
The class code shall be included in the specification as described in Clause 9.

Due to the statistical distribution pattern of the properties the values shall be presented as:
- net calorific value (NCV) mean (arithmetic);
- chlorine content (Cl) mean (arithmetic);
th
- mercury content (Hg) median and 80 percentile.
th
The highest of the two statistical values (median and 80 percentile) in a Hg data set determines the
th
class (a SRF with a median value of 0,03 and a 80 percentile value of 0,07 belongs to Hg class 3).

For NCV, Cl and Hg the test methods in the corresponding prCEN/TS shall be used.
th
NOTE 1 80 percentile is the value on or below which 80 % of the observations fall.
NOTE 2 For details on statistics see CEN Report prCEN/TR 15508 ”Key properties of solid recovered fuels to
be used for establishing a classification system”.
NOTE 3 The averages and percentiles are determined on the quantity of SRF as specified in Clause 8.
NOTE 4 The classes have been determined as a tool for identifying and pre-selecting SRF. However, the
performances of the plant where a SRF is used are depending on the properties of the SRF and more significantly
on the design and operating conditions of such a plant.
