Kružna ekonomija u prehrambenoj industriji i industriji pića, visokovrijedni proizvodi te energetsko i materijalno iskorištavanje otpada i nusproizvoda
Gregor Drago Zupančič, Mario Panjicko, Anamarija Havliček, Goran Lukić, 2019, published scientific conference contribution abstract

Abstract: Prehrambena industrija i industrija pića su s godišnjim prihodima od 1190 milijardi € među najvažnijim granama gospodarstva u EU, koje također proizvode i značajne količine nusproizvoda i otpada. Posljednjih godina, kroz uvođenje strategija kružne ekonomije, posebna pažnja posvećuje se iskorištavanju otpadnih tokova iz kojih je moguća proizvodnja visokovrijednih proizvoda. U ovom radu prikazani su primjeri iz proizvodnje hrane i pića, u kojima je iz nusproizvoda moguće proizvoditi aktivne spojeve kao npr. Resveratrol koji ima antikancerogeni učinak, različite polu proizvode kao što su fenolni spojevi, dodaci u prehrani i sl. U radu je posebna pažnja posvećena pivarskoj industriji gdje se iz nusproizvoda (pivske komine) proizvode prehrambeni proteini te i mljekarskoj industriji gdje se iz sirutke proizvode mliječne kulture, vitamini, laktoza, laktat i proteini (npr. aktoferini, laktoperoksidaze, imunoglobulini). U smislu strategije kružne ekonomije, ostatci nakon dobivanja novih proizvoda, koji više ne sadrže vrijedne tvari, moraju se zbrinuti na odgovarajući način. Najpovoljnija i najčešće upotrebljena tehnologija zbrinjavanja je anaerobna digestija. Anaerobnom digestijom moguće je otpadne tokove zbrinuti na način da se količine otpada smanje i do 90% te da se proizvedeni bioplin upotrijebi kao obnovljiv izvor energije u samom proizvodnom procesu. Time je moguće ostvariti smanjuje emisija ugljičnog dioksida do 50%.

Biogas production from brewery yeast in an EGSB reactor
Romana Marinšek-Logar, Matej Oset, Miran Klemenčič, Milenko Roš, Gregor Drago Zupančič, 2016, professional article

Abstract: Experience over a five-year period of full throughput using anaerobic co-digestion of brewery yeast for biogas production is described in this contribution. The brewery, with a total amount of available yeast (0.7 v/v %), had a 26.2 % increase in COD load and a 38.5 % increase in biogas production resulting in an increase in the biomethane/natural gas substitution ratio in the brewery from 10 % to 16 %.

Biogas Production from Brewer’s Yeast Using an Anaerobic Sequencing Batch Reactor
Gregor Drago Zupančič, Mario Panjicko, Bruno Zelić, 2017, original scientific article

Abstract: Renewable energy sources are becoming increasingly important in the beverage and food industries. In the brewing industry, a significant percentage of the used raw materials finishes the process as secondary resource or waste. The research on the anaerobic digestion of brewer’s yeast has been scarce until recent years. One of the reasons for this is its use as a secondary resource in the food industry and as cattle feed. Additionally, market value of brewer’s yeast is higher than its energy value. Due to the increase of energy prices, brewer’s yeast has become of interest as energy substrate despite its difficult degradability in anaerobic conditions. The anaerobic co-digestion of brewer’s yeast and anaerobically treated brewery wastewater was studied using a pilot-scale anaerobic sequencing batch reactor (ASBR) seeded with granular biomass. The experiments showed very good and stable operation with an organic loading rate of up to 8.0 kg/(m3·day), and with a maximum achieved organic loading rate of 13.6 kg/(m3·day) in a single cycle. A specific biogas productivity of over 0.430 m3/kg of the total chemical oxygen demand (COD) inserted, and total COD removal efficiencies of over 90 % were achieved. This study suggests that the brewer’s yeast can be successfully digested in an ASBR without adverse effects on the biogas production from brewer's yeast/wastewater mixtures of up to 8 % (by volume). By using the brewer's yeast in the ASBR process, the biogas production from brewery wastewater could be increased by 50 %.
