Abstract
Bioplin je produkt koji nastaje anaerobnom probavom gdje različiti mikroorganizmi različitim metaboličkim putevima razgrađuju organsku tvar. Bioplin ima veliki potencijalni izvor energije, a tehnologija proizvodnje bioplina povoljna je zbog zaštite okoliša i smanjenja stakleničkih plinova. Republika Hrvatska ima povoljne agroekološke uvjete za uzgoj vinove loze, a sa time i proizvodnju vina. Pri proizvodnji vina nastaje nusproizvod točnije fermentirani masulj, komina ili talog. Vinarima je odlaganje vinskog otpada neekonomično, a mala nutritivna vrijednost čini kominu neprikadnu kao hranu za preživače. Goveđa gnojovka kao kontrolni supstrat ima nisku koncentraciju suhe tvari, odnosno 5,35 % suhe tvari. Komine imaju veći postotak suhe tvari, a prosječna vrijednost 38,23 %. Udio hlapljive i organske tvari je u visokim granicama, što je važno za proizvodnju bioplina. Kod svih skupina dinamika proizvodnje praćena je tijekom razdoblja od 28 dana. Kontrolna skupina proizvela je prosječnu vrijednost od 4906,67/500 ml bioplina. Kontrolnu skupinu su nadmašile eksperimentalne skupine gdje se prosječna vrijednost kreće od 10933,33 do 14273,33 ml/500 ml bioplina. Najveća proizvodnja metana po gramu suhe organske tvari (mlCH 4 /gOT) u iznosu od 648,92 ml ostvarila je komina Graševine Aljmaš.
Abstract (english)
Biogas is a product produced by anaerobic digestion, where different microorganisms break down organic matter through different metabolic pathways. Biogas has a large potential source of energy, and biogas production technology is favorable due to environmental protection and reduction of greenhouse gases. The Republic of Croatia has favorable agroecological conditions for the cultivation of vines, and with it the production of wine. During the production of wine, a by-product is created, more precisely fermented mash, pomace or lees. It is uneconomical for winegrowers to dispose of wine waste, and the low nutritional value makes pomace unsuitable as food for ruminants. Bovine slurry as a control substrate has a low concentration of dry matter, i.e. 5.35% dry matter. Pomace has a higher percentage of dry matter, and the average value is 38.23%. The proportion of volatile and organic matter is within high limits, which is important for biogas production. In all groups, the dynamics of production was monitored over a period of 28 days. The control group produced an average value of 4906.67/500 ml of biogas. The control group was surpassed by the experimental groups, where the average value ranges from 10933.33 to 14273.33 ml/500 ml of biogas. The largest production of methane per gram of dry organic matter (mlCH 4 /gOT) in the amount of 648.92 ml was achieved by the Graševine Aljmaš pomace.
