NOVELTY - Producing fuel briquettes (4) from renewable resources, comprises: subjecting a raw material mixture (1) comprising non-woody or non-lignified fine material and woody or lignified structural material, preferably a raw material mixture of accumulating wood residues obtained from the thinning and harvesting of stem wood in forestry, bark and wood arising from short rotation plantations with plants and/or plant components obtained from landscape conservation to at least one single-stage decomposition process; and providing partially rotten raw material mixture.    USE - The method is useful for producing fuel briquettes from renewable resources.    ADVANTAGE - The method: utilizes renewable raw materials having high calorific value and low energy consumption, thus it is cost efficient; and produces fuel briquettes with high durability, and which are dimensionally stable and unbreakable during loading and packing.    DETAILED DESCRIPTION - Producing fuel briquettes (4) from renewable resources, comprises: subjecting a raw material mixture (1) comprising non-woody or non-lignified fine material and woody or lignified structural material, preferably a raw material mixture of accumulating wood residues obtained from the thinning and harvesting of stem wood in forestry, bark and wood arising from short rotation plantations with plants and/or plant components obtained from landscape conservation to at least one single-stage decomposition process, where the decomposition process is performed such that the fine material of the raw material mixture is biologically converted at least up to a degree of rotting-2 and up to a maximum degree of rotting-3; and providing the partially rotten raw material mixture for the production of fuel briquettes. An INDEPENDENT CLAIM is also included for fuel briquettes obtained from the above mentioned method.
