Seed cakes, by-products from the cold press extraction of vegetable oils, are valuable animal feed supplements due to their high content proteins, carbohydrates, and minerals. However, presence anti-nutrients, as well rancidification development aflatoxins, can impede intended use, requiring alternative treatment valorisation methods. Thermal a procedure for conversion seed cakes walnuts, hemp, pumpkin, flax, sunflower into products or energy has been investigated in this paper. Thermogravimetry shows particular behaviour with several degradation stages at around 230–280 340–390 °C, before after typical cellulose. These related volatilisation fatty acids, which either free bonded triglycerides, thermal proteins. Torrefaction 250 °C produced ~75–82 wt% solids, calorific values 24–26 kJ/g an yield above 90%. The liquid have complex composition, most parts compounds partitioning between aqueous phase (strongly dominant) oily one (present traces). structural components (hemicelluloses, cellulose, lignin) produce acetic acid, hydroxy ketones, furans, phenols. In addition these, nitrogen-containing aromatic protein components, highly present cakes.
