Language in which you want to receive the document.


This document determines the fuel quality classes and specifications of graded non-woody briquettes. This document covers only non-woody briquettes produced from the following raw materials (see ISO 17225‑1:2021, Table 1):
—    2 Herbaceous biomass
—    3 Fruit biomass
—    4 Aquatic biomass
—    5 Biomass blends and mixtures
NOTE 1    Herbaceous biomass originates 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.
NOTE 2    Blends and mixtures include blends and mixtures from the main origin-based solid biofuel groups woody biomass, 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 is to be described using ISO 17225‑1:2021, Table 1.
If solid biofuel blend or mixture contains chemically treated material it shall be stated.
NOTE 3              Thermally treated biomass briquettes (e.g. torrefied briquettes) are not included in the scope of this document
