Solid biofuels - Determination of water sorption and its effect on durability of thermally treated biomass fuels - Part 1: Pellets (ISO 23343-1:2021)
This document describes a method for determination of sorption of graded thermally treated and densified biomass fuels such as classified in ISO/TS 17225-8.
Apart from pelletized materials as described in ISO/TS 17225-8, the method can also be applied to non-compressed or non-densified thermally treated biomass as specified in ISO 17225-1 Table 14 and Table 15.

ISO 23343-1:2021(E)
Introduction
Thermally treated biomass fuels, particularly in compressed form, are increasingly considered as a
replacement of fossil coal or for co-firing in large energy plants for production of heat and/or power.
Compressed biomass fuels which are not thermally treated easily absorb moisture; this compromises
the durability and generates fines. Thermally treated biomass fuels vary in their affinity to absorb
moisture (absorption and/or adsorption – here collectively called sorption) depending on the extent
and/or type of thermal treatment, feedstock used to make the product, compression, potential additives
used, etc. For this purpose, it is important to understand the degree to which thermally treated
compressed solid biofuels are resistant to moisture uptake and the degree to which they maintain
durability when exposed to moisture, primarily in the form of rain during outdoor storage.
Thermally treated biomass fuel such as pellets or briquettes may be classified based on these
characteristics as suitable or unsuitable to be handled and stored under conditions with limited or no
weather protection. This document was developed specifically for the classification of pellets and is not
intended to be applicable to other forms of densified fuel (e.g. briquettes). It is intended that other parts
will be developed as necessary to apply these principles to other forms of thermally treated biomass
fuels.
It should be noted that in large-scale storage of thermally treated biomass fuels the degree of
wetting will likely vary within the storage. Therefore, this document is not intended to be used to
draw conclusions on the average degree of wetting for any particular storage, but rather provides an
indication of the degree to which durability and/or moisture content can be affected under worst case
conditions. This method can be used for comparative purposes towards other pelletized thermally
treated biomass fuels.

1 Scope
This method allows for the determination of water sorption in a laboratory setting and provides a
measure for how the durability is impacted as a result of immersion in water. Post-immersion durability
reduction is calculated as the difference between the durability of the as-received sample and the
durability of the wetted product.
A post-immersion durability reduction of 0 means there was no change to the durability of the
thermally treated pelletized fuel as a result of wetting, whereas a post-immersion durability reduction
of 3 indicate that the durability dropped by three percentage points as a result of wetting.
