Description / Abstract:
This International standard determines the fuel quality classes
and specifications of graded non-woody pellets. This International
standard covers only non-woody pellets produced from the following
raw material (see ISO 17225–1, Table 1):
-2 Herbaceous biomass
NOTE 1 Herbaceous biomass is from plants that have a non-woody
stem and which die back at the end of the growing season. It
includes grains or seeds crops from food production or processing
industry and their by-products such as cereals.
-3 Fruit biomass
-4 Aquatic biomass
-5 Biomass blends and mixtures
NOTE 2 Group 5 Blends and mixtures include blends and mixtures
from the main origin-based solid biofuel groups woody, herbaceous
biomass, fruit biomass and aquatic biomass.
Blends are intentionally mixed biofuels, whereas mixtures are
unintentionally mixed biofuels. The origin of the blend and mixture
has to be described using ISO 17225-1 Table 1.
If solid biofuel blend or mixture contains chemically treated
material it shall be stated.
NOTE 3 Thermally treated pellets (e.g. torrefied pellets) are
not included in the scope of this International Standard.
Torrefaction is a mild pre-treatment of biomass at a temperature
between 200 °C to 300 °C.
