TECHNOLOGY FOCUS - BIOLOGY - Preferred Process: In the process, immediately after extrusion, the pellet obtained by extrusion has a temperature of 55 degrees C-65 degrees C. The process further comprises a drying phase, during which at least one of the vegetable materials is dried, where the drying phase precedes the extrusion phase. Preferred Components: The mixture has a humidity component of approximately 10-25 wt.%, preferably 15-20 wt.%. The mixture has a weight percentage of the oily vegetable component below approximately 25. The first and second vegetable materials are obtained from a raw materials comprising woody stalks and branches, wood, straw, grass, leaves, grassy stalks (stems) and branches, leaves, fruit, seeds, sunflower, maize, colza, grapes, olives, sorghum, maize cob, maize seed, main body (stalk) of sunflower, sunflower inflorescence, sunflower seed, main body of sorghum, sorghum seed, main body of colza, colza seed, sunflower cake, grape pomace, grape seeds or olive pomace. The first vegetable material is obtained from a raw material comprising woody stalks and branches, grassy stalks and branches, or leaves. The second material is obtained from raw material comprising sunflower seed, maize seed, colza seed, sorghum seed or grape seeds. The mixture comprises at least a third particulate of a third vegetable material different from the first and the second vegetable material. The mixture comprises wood (at least 20%) and/or sunflower seeds (at least 15%). (I) has an oily vegetable component of below 25 wt.%. The vegetable starch component is present at 5-20 wt.%. The fiber component is present at 80 wt.%. (I) comprises at least a third vegetable material different from the first and second vegetable material. EXAMPLE - Wood (30 wt.%), olive pomace (57 wt.%), sunflower (3 wt.%) and maize (seed and cob) (10 wt.%) were mixed together to obtain a mixture. The mixture was pelletized using pelletizer, which has extrusion holes with diameter of 3 mm and operated at approximately 60 degrees C to give a pellet.
