Namen dela je bil osnovati koncept integriranega ravnanja z odpadnimi blati in
biorazgradljivimi odpadki Gorenjske regije, ki bi bil skladen z zakonodajo in ekonomsko
izvedljiv. Avtorica je proučila relevantne strategije EU in RS o ravnanju s tovrstnimi odpadki,
zakonodajo ter uveljavljene dobre prakse (IPPC direktiva/BAT/BREF). Preverjeni so bili
alternativni sodobni postopki obdelave odpadnih blat in biorazgradljivih odpadkov ter
opravljena SWOT analiza. Izvedena je bila raziskava trenutnega stanja ravnanja s tovrstnimi
odpadki v Gorenjski regiji. Eksperimentalno so bile preverjene tri opcije sodobnega ravnanja.
Ugotovitve so podprte s fizikalno – kemijskimi – biološkimi analizami vhodnih materialov in
končnih produktov ter z lastnostmi in uporabnostjo produktov po različnih alternativah.
Proučen je tudi ekonomski vidik različnih alternativ. Na osnovi dobljenih podatkov je
predlagan najbolj primeren način integrirane obdelave odpadnih blat in biorazgradljivih
odpadkov za območje Gorenjske regije, ki je anaerobna razgradnja s pridobivanjem bioplina
ter kompostiranjem preostanka. Predvidene so vhodne količine tovrstnih odpadkov ter
velikost in lokacija Centra za integrirano ravnanje z odpadnimi blati in biorazgradljivimi
odpadki Gorenjske regije. V centru ob anaerobni razgradnji nastaja bioplin, ki služi za
kogeneracijo električne in toplotne energije. Predvidena nazivna moč kogeneracije je 260 kW
elektrike in 375 kW toplote. Obdelava pregnitega blata s kompostiranjem se izvaja v
kompostarni izven centra. Na osnovi predvidenih stroškov in prihodkov je izračunana vračilna
doba investicije v center, ki znaša 12 let.

Planning the integrated treatment of waste sludges and biodegradable wastes in Gorenjska region |
Sekundarni povzetek: |
The purpose of work was to establish the concept of integrated treatment of waste sludges and
biodegradable wastes in Gorenjska region, which should be accordant with legislation and
economicaly feasible. Adequate EU and RS strategies, legislation and well-known good
practises (IPPC directive/BAT/BREF) were studied. Alternative contemporary proceedings
for waste sludges and biodegradable wastes treatment were checked and compared by SWOT
analysis. An examination of actual treatment with such kind of wastes was carried out for
Gorenjska region. Three different options of contemporary biodegradable wastes and waste
sludges treatment were experimentally checked. Findings were corroborated with physical –
chemical – biological analyses of entry materials and final products and also with
characteristics and products applicability of single option. An economic seight was studied for
single option, too. In view of received data the most appropriate method for integrated
treatment of waste sludges and biodegradable wastes in Gorenjska region was proposed;
namely anaerobic digestion with biogas production, followed by composting of the residue.
Entry quantities of waste sludges and biodegradable wastes were anticipated; also size and
site of the Centre for integrated treatment of waste sludges and biodegradable wastes of
Gorenjska region were suggested. In the centre considerable quantities of biogas can be
produced and utilised for electricity and heat cogeneration. The coproduction was estimated
of about 260 kW electricity power and 375 kW heat power. Composting of the digested
sludge takes place in special unit out of the centre. On the base of expected costs and incomes
the 12 years return period of investment in the centre was calculated. |
