Abstract

Nakon zimske rezidbe vinove loze i voćaka ostaju velike količine orezane biomase. Jedna od mogućnosti ekološko prihvatljivog zbrinjavanja je korištenje orezane biomase kao sirovine u procesu proizvodnje energije. Količine potencijalno dostupne biomase značajno ovisi o sorti i vrsti kao i agroekološkim uvjetima lokacije uzgoja. Cilj diplomskog rada je na području Krapinsko-zagorske županije utvrditi: (I) prosječnu masu ukupne orezane biomase po istraživanoj vrsti/sorti, (II) teoretski, tehnički i energetski potencijal (III) prostornu distribuciju orezane biomase. Uzorkovanje biomase provedeno je tijekom zimske rezidbe 2022. godine na 43lokacije unutar područja Krapinsko-zagorske županije. Istraživanjem je obuhvaćeno 6 voćnih vrsta i 17 sorti vinove loze. Ukupna prostorna distribucija orezane biomase i potencijalne energije unutar Krapinsko-zagorske županije temeljena je na Arkod bazi podataka iz 31.12. 2021. godine. Ukupna površina pod vinogradarskom proizvodnjom iznosi 667 ha, dok se uzgoj voćnih sorti provodi na površini od 1 316 ha. Sukladno postavljenoj metodologiji energetski potencija orezane biomase vinove loze se kreće od 24 605 do 32 176 GJ, dok se iz orezane biomase voćnih vrsti može proizvesti od 43 555 do 56 965 GJ energije.

Abstract (english)

After the winter pruning of vines and fruit trees, large amounts of pruned biomass remain. One of the options for environmentally acceptable disposal is the use of harvested biomass as a raw material in the energy production process. The amount of potentially available biomass significantly depends on the variety and species as well as the agroecological conditions of the cultivation location. The aim of the thesis is to determine in the Krapina-Zagorje County: (I) the average mass of the total pruned biomass per investigated species/variety, (II) the theoretical, technical and energy potential (III) the spatial distribution of the pruned biomass. Biomass sampling was carried out during winter pruning 2022 at 43 locations within the Krapina-Zagorje County. The research covered 6 fruit species and 17 vine varieties. The total spatial distribution of harvested biomass and potential energy within the Krapina-Zagorje County is based on the Arkod database from December 31. in 2021. The total area under viticulture production is 667 ha, while the cultivation of fruit varieties is carried out on an area of 1,316 ha. According to the established methodology, the energy potential of pruned vine biomass ranges from 24 605 to 32 176 GJ, while pruned biomass of fruit species can produce from 43 555 to 56 965 GJ of energy.
