Description / Abstract:

This International Standard determines the fuel quality classes and specifications of graded non-woody briquettes. This International Standard covers only non-woody briquettes produced from the following raw materials (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 briquettes (e.g. torrefied briquettes) are not included in the scope of this International Standard. Torrefaction is a mild pre-treatment of biomass at a temperature between 200 – 300 °C.
