Abstract:Vsako leto se soočamo s porastom količine proizvedenih odpadkov, ki predstavljajo veliko obremenitev za naše okolje, če z njimi ne ravnamo pravilno. Med te proizvedene odpadke sodi tudi biomasa (e.g., odpadni mulji, odpadno perje, odpadne rastline, lesni sekanci etc.), ki pa ima številne priložnosti, kot recimo potencial za njeno ponovno pametno uporabo. Znano je namreč, da odpadna biomasa predstavlja trajen in obnovljiv vir surovine in energetsko varčni material (malo energije za njihovo pridelavo in predelavo), ter hkrati omogoča možnost recikliranja. Ena izmed ekoloških, hkrati tudi ekonomskih najbolj sprejemljivih rešitev, trajnostno zbiranje mulja, je njegova ponovna uporaba v poljedelstvu. Eden od najbolj sprejemljivih postopkov obdelave mulja, pri katerem dobimo stranske produkte, je piroliza. V tej magistrski nalogi smo s pomočjo pirolize iz odpadnega mulja dobili biooglje in dve frakciji, težkohlapno in lahkohlapno. Iz dobljenih produktov smo v podjetju Gorenje Surovina d.o.o. določili kalorično vrednost, vsebnost pepela in vlage. Rezultate meritev težkih kovin, PAH, CHN in hlapnih komponent v biooglju, smo dobili iz podjetja IKEMA d.o.o. Ob tem, so opravili eksperiment tako, da so posadili semena kreše v petrijevke ter v njih vstavili določeno koncentracijo biooglja in šote. V četrtem poglavju so prikazani rezultati iz katerih lahko potegnemo zaključek, da se dobljeno oglje v določenih koncentracijah lahko uporablja kot dodatek tlom. Zaradi svojih lastnosti se znatno izboljša kvaliteto in strukturo tal za boljšo rast rastlin, v našem primeru, kreše. Na osnovi rastnega in kalilnega testa smo dobili rezultate, ki smo jih analizirali v sledeče parametre: kaljivost (GR), dolžino korenine rastline (RLP), indeks dolžine korenine (IR) in Munoo – Liisa indeks vitalnosti (MLV) ob določeni koncentraciji biooglja in šote.

Title:Development of fertilisers from sludge
Abstract:Every year we notice increased amount of waste that has a bad impact on the environment if we do not take proper care of it. Bio-waste (e.g., waste sludge, waste feathers, waste plants,wood chips etc.) has many potentials and one of them is possibility to reuse materials. Biomass waste is sustainable and renewable source of raw material, it is energy efficient (low amount of energy is needed for its production and processing) and recycable. One of the most acceptable procedures of slit treatment is pyrolysis, in which we obtain byproducts. Biochar has been obtained in this research by using pyrolysis on sewage silt, alongside two fractions, one highly volatile, the other low volatile. The calorific value, ash and volatility content of the products have been obtained in the company Gorenje Surovina. The company IKEMA provided the results of heavy metal measurements, PAH, CHN and volatile components from the biochar. Apart from this, they made an experiment by sowing tall whitetop seeds in petri dishes and adding specific biochar and peat concentrations. In part 4 of the paper the results are shown which allow us to deduce that obtained biochar can be used as a soil supplement in certain concentrations. Because of its properties, biochar greatly increases soil quality and structure for a better plant growth, in our case tall whitetop. Based on the results of the growth and calory test the following parameters were analysed: germination rate (GR), the length of the root (RLP), the root length index (RI), and MunooLiisa vitality index (MLV) with specific biochar and peat concentrations.
Keywords:waste sludge, pyrolysis, biochar, fraction, growth in calory test
