Solid recovered fuels - Method for the determination of biomass content
This Technical Specification specifies two normative methods and one informative method for the determination of the biodegradable/biogenic fraction in solid recovered fuel. The methods are the selective dissolution in sulphuric acid, the manual sorting method and the informative reductionistic method. The methods estimate the biodegradable/biogenic content of solid recovered fuels by determination of the biomass content.
This Technical Specification is not applicable to:
- pure fractions of waste, products and by-products classified as CO2-neutral biomass according to Annex G;
- charcoal, peat and solid fossil fuels like hard coal, coke, brown coal and lignite and to mixtures of these and solid recovered fuels;
- solid recovered fuels that contain more than 10 % of natural and/or synthetic rubber residues;
- solid recovered fuels that contain a combination of more than 5 % by weight of:
- nylon, polyurethane or other polymers containing molecular amino groups;
- biodegradable plastics of fossil origin;
- solid recovered fuels that contain a combination of more than 5 % by weight of:
- wool or viscose;
- non-biodegradable plastics of biogenic origin;
- oil or fat present as a constituent of biomass.
NOTE In typical municipal and assimilated waste the content of nylon, polyurethane, biodegradable plastics of fossil origin, wool, viscose, non-biodegradable plastics of biogenic origin and oil/fat present is rather small and the error is negligible.

Foreword
This document (CEN/TS 15440:2006) has been prepared by Technical Committee CEN/TC 343 “Solid
recovered fuels”, the secretariat of which is held by SFS.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This Technical Specification is one of a series of technical specifications dealing with solid recovered fuels.
Solid recovered fuels are defined in the EU Commission Mandate M/325 to CEN. The mandate makes
reference to Directive 2001/77/EC, 2000/76/EC and Commission Decision 2000/532/EC. In the Mandate
M/325 solid recovered fuels are defined as fuels prepared from non hazardous waste to be utilised for energy
recovery in waste incineration or co-incineration plants regulated under Community environmental legislation.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden,
Switzerland and the United Kingdom.
Introduction
This Technical Specification specifies the methods used for the determination of biomass (as defined in 3.3)
content in solid recovered fuels. The RES-E directive [1] aims to promote electricity produced from renewable
resources, including e.g. the biomass fraction present in solid waste. This Technical Specification specifies
two normative methods and one informative method for the determination of biomass content in solid
recovered fuels, including the method of selective dissolution in sulphuric acid, the manual sorting method and
the informative reductionistic method. The reductionistic method is for internal control and specific agreements
only, see Annex F. The two latter methods are both based on the first one, the selective dissolution method.
As the selective dissolution method is not applicable to some materials usually or possibly present in SRF, the
limitations of this method have to be considered (see Annex G), and attention needs to be paid to possible
misuse in SRF mixtures of unknown origin.
NOTE An alternative method could be the C-14 method to determine the biomass content expressed in percentage
by carbon content. The method is currently in its early stages of development, but in the future it may be used as an
alternative method to determine the biomass content expressed in percentage by carbon content.
This Technical Specification is primarily geared toward laboratories, producers, suppliers and purchasers of
solid recovered fuels, but is also useful for the authorities and inspection organizations.
CEN/TR 14980 shows that biogenic/biodegradable fractions can be estimated using the methods described in
this Technical Specification. The fraction of biomass (biodegradable/biogenic fractions) can be expressed:
by weight;
by energy content (net or gross calorific value);
by carbon content.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 13965-1:2004, EN 13965-2:2004
and the following apply.
NOTE Definitions for the terms in bold are given in EN 13965.
3.1
ash content
inorganic mass remaining after complete combustion of a solid recovered fuel under specified conditions
expressed as a percentage of the mass of the dry matter in the solid recovered fuel
[CEN/TS 15357:2006]
3.2
biodegradable
material capable of undergoing biological anaerobic or aerobic decomposition under conditions naturally
occurring in the biosphere
3.3
biomass
material of biological origin excluding material embedded in geological formation or transformed to fossil
NOTE This definition is very close to the definition in CEN/TC 335 “Solid biofuels” with the only difference that coal
found on the surface of the earth is clearly excluded. For further clarification, definitions on fossil and geological formation:
fossil
remains or traces of a plant or animal life embedded in geological formation from a previous geological period
and transformed to a stable material for the conditions of its present location
geological formation
material formed by consecutive natural depositions of different materials in a certain geological period
3.4
biogenic

3.5
calorific value
calculated value of the specific energy of combustion for unit mass of a solid recovered fuel burned in oxygen
in calorimetric bomb under such conditions that it can be either expressed as gross calorific value or net
calorific value
3.6
gross calorific value
absolute value of the specific energy of combustion for unit mass of a solid recovered fuel burned in oxygen
in calorimetric bomb under the conditions specified
NOTE 1 The result of combustion are assumed to consist of gaseous oxygen, nitrogen, carbon dioxide and sulphur
dioxide, of liquid water [in equilibrium with its vapour] saturated with carbon dioxide under conditions of the bomb reaction,
and of solid ash, all at the reference temperature and at constant volume.
NOTE 2 The old term for gross calorific value is higher heating value.

increment sent to a laboratory

3.9
total moisture
moisture in a solid recovered fuel removable under specific conditions
NOTE the old term for total moisture is moisture content.
3.10
net calorific value
calculated value of the specific energy of combustion for unit mass of a solid recovered fuel burned in oxygen
in calorimetric bomb under such conditions that all the water remains as water vapour at 0,1 MPa

NOTE The old term for net calorific value is lower heating value.
3.11
nominal top size
aperture size of the sieve used for determining the particle size distribution of solid recovered fuels
through which at least 95 % by mass of the material passes
[CEN/TS 15357:2006]

sample
quantity of material, representative of a larger quantity for which the property is to be determined
3.13
sample preparation
all the actions taken to obtain representative analyses samples or test portions from the original sample

unequal size
NOTE 1 A sub-sample may be:
a) a portion of the sample obtained by selection or division;
b) the final sample of multistage sample-preparation.
NOTE 2 The definition for sub-sample is adopted fr
