Sekundarni naslov:	Development of treatment processes for the waste wood ash
Sekundarni povzetek:	Wood ash is a high quality waste that is generated by thermal utilization of fresh and waste wood. The material is too valuable to waste it. Ashes are often found unsuitable for disposal at landfills or for direct application due to their dusty consistency, high content of soluble substances and unburned carbon or their alkalinity. With relatively simple procedures we can make it to a form suitable for utilization or disposal. These processes are: spontaneous or forced carbonization, granulation, preparation of artificial soil or their integration into other complementary waste like compost and digestate sewage sludge. Options of handling wood ashes are represented in this study. At first the treatment of waste wood ashes in Slovenia and Europe is presented. In the experimental part an attempt to integrate different portions of wood ashes into compost and dehydrated sewage sludge is studied, to get a stabilized product. After two months of aging, under appropriate external conditions, I get the end products that have some quality characteristics that allow their use in various areas. It can be used for rehabilitation degraded forests and soil, for landfill cover, for covering mine tailings, in construction or for fertilization in agriculture and improvement of acidic soils, which allows mineral structure and the corresponding pH of these products.

Povzetek (ePrints):	Odpadni lesni pepel je kakovosten odpadek kurjenja lesa, ki ima preveliko vrednost, da bi ga odlagali in ne s pridom izkoriščali. Njegova neposredna uporaba na različnih področjih je omejena, predvsem zaradi njegove praškaste konsistence, vsebnosti vodotopnih snovi, vsebnosti nezgorelega lesa (oglja) in bazičnosti. Z relativno enostavnimi postopki ga lahko privedemo v obliko primerno za snovno izrabo oz. za odlaganje. Ti postopki so: spontana ali vsiljena karbonatizacija, granuliranje, integriranje odpadka v zemeljski izkop oz. priprava umetne zemljine ali integriranje v drug komplementaren odpadek (komposti, blata …). V diplomski nalogi sem predstavila možne postopke ravnanja z odpadnimi lesnimi pepeli pri nas in v Evropi ter v eksperimentalnem delu naloge prikazala enega od postopkov predelave odpadnega lesnega pepela v stabiliziran proizvod. Različne količine odpadnega lesnega pepela sem integrirala v dva prav tako odpadna materiala, to je dehidrirano blato iz čistilne naprave in kompost. Mešanice so se pod ustreznimi zunanjimi pogoji, to je zadostni vlagi in prezračenosti, starale in tako stabilizirale. Po preteku dveh mesecev sem dobila proizvode z ustreznimi lastnostmi, ki omogočajo njihovo uporabo na različnih področjih. Bodisi za sanacijo gozdnih in degradiranih tal, kot prekrivka odlagališč ali drugih odpadkov (rudarskih jalovin), v gradbeništvu, za razna sanacijska zemeljska dela, še najbolj pa se uporabljajo v kmetijstvu za gnojenje in izboljševanje kislih prsti, kar omogoča njegova bogata mineralna struktura in ustrezen pH.
