20.500.12556/DiRROS-19769 Pridobivanje in uporaba ekstraktivov iz lesa in drevesne skorje Obtaining and use of extractives from wood and tree`s bark Ekstraktivi so nizkomolekularne spojine, ki so v vseh rastlinskih tkivih, tudi v lesu in drevesni skorji. V drevesu imajo pomembne ekološke in fiziološke funkcije, obenem pa predstavljajo bioosnovane proizvode z visoko dodano vrednostjo, ki jih je mogoče pridobivati tudi iz lesa slabše kakovosti in biomasnih ostankov gozdnih lesnih verig. V prispevku bomo ekstraktive razvrstili, pojasnili, kakšna je kakovostna in količinska spremenljivost po posameznih tkivih izbranih drevesnih vrst, predstavili bomo načine pridobivanja in področja uporabe. Ocenjujemo, da je pridobivanje ekstraktivov dokaj enostaven tehnološki postopek, ki bi bil v obliki manjše biorafinerije izvedljiv v lokalnih okoljih, kjer so na voljo zadostne količine lesne biomase. Extractives are low molecular weight compounds found in all plant tissues, including wood and tree bark. They have important ecological and physiological functions in trees, and at the same time, they represent bio-based products with high added value, which can also be obtained from wood of lower quality and biomass residues of forestry-wood chains. In this paper, we will classify extractives, explain the qualitative and quantitative variability in individual tissues of the selected tree species, and present the methods of extraction and areas of application. We estimate that the production of extractives is a fairly simple technological process that would be feasible in the form of a small biorefinery in rural environments where sufficient amounts of wood biomass are available. les skorja ekstraktivi kaskadna raba biorafinacija wood bark extractives cascade use biorefining true false true Slovenski jezik Angleški jezik Neznano 2024-07-24 15:08:23 2024-07-24 15:08:23 2024-07-26 03:49:43 0000-00-00 00:00:00 2024 0 0 str. 75-82 št. 2 Letn. 82 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-01-01 630*81 0017-2723 202659331 RAZ_Oven_Primoz_2024.pdf RAZ_Oven_Primoz_2024.pdf 1 9BCE2EAF5227454A9AC440D21FA215B0 2c7f13e3cc1287ddcdbac24b4788da001ce67acfa987071708aadeb7dfa50063 1c903b57-49ad-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27375 Zveza gozdarskih društev Slovenije Gozdarski vestnik 0 0 0
