— 1.1 Forest, plantation and other virgin wood
— 1.2 By-products and residues from wood processing industry
— 1.3.1 Chemically untreated used wood
— 2. Herbaceous biomass
— 3. Fruit biomass
— 4. Aquatic biomass.
Subcategories of the above stated raw materials are included.
This document does not consider products, which are marketed as charcoal or as charcoal products.
For these products, ISO 17225-1:2014, Table 14 shall apply.
NOTE 1 For thermally treated powder, ISO 17225-1:2014, Table 15 or Table 16 may be used for specification.
NOTE 2 Health, safety and environmental issues for solid biofuels are important and need special attention
however, they are outside the scope of this document.
