Scope

This document determines the fuel quality classes and specifications of graded densified solid biofuels produced from thermally treated biomass for commercial and industrial use. Thermal treatment includes processes such as torrefaction, steam explosion, hydrothermal carbonization and charring, all of which represent different exposure to heat, oxygen, steam or water. This document covers pellets and briquettes produced from the following raw materials (see ISO 17225-1, Table 1):

— 1. Woody biomass;

— 2. Herbaceous biomass;

— 3. Fruit biomass;

— 4. Aquatic biomass;

— 5. Blends and mixtures.

Subcategories of the above stated raw materials are also included.

This document does not consider products, which are marketed as charcoal or as charcoal products. For these products, ISO 17225-1, Table 14 shall apply.

Purpose

The objective of this document is to provide unambiguous and clear classification principles for densified solid biofuels produced from thermally treated biomass, to serve as a tool to enable efficient trading of biofuels, to enable good understanding between seller and buyer as well as to serve as a tool for communication with equipment manufacturers. It will also facilitate authority permission procedures and reporting.
