Abstract:Diplomsko delo vsebuje optimiranje bioprocesov, proizvodnje biodizla in bioplina, pri katerih smo hkrati upoštevali tri vidike: ekonomski, okoljski in socialni vidik. Namen diplomske naloge je bil proučiti, kako vplivajo posamezni kriteriji, ekonomski (dobiček), okoljski (takse za CO2) in socialni (število delovnih mest) na celotni trajnostni kriterij pri različnih kapacitetah za oba bioprocesa. Optimiranje smo izvedli v programu GAMS. Izvedli smo tudi občutljivostno analizo, kjer smo odgovorili na vprašanje, pri kakšni kapaciteti morajo potekati procesi, da dobimo rentabilen proces. Proizvodnja biogoriv iz vidika celotnega trajnostnega kazalca je trajnostna. Le v primeru, ko smo minimirali okoljski dobiček, smo dobili negativni trajnostni kriterij. Vzrok je minimalna količina proizvodnih surovin, ki zmanjša ekonomski dobiček. Socialni vidik je pozitiven zaradi večjega števila delovnih mest. Obratovati je potrebno z veliko kapaciteto, da dobimo pozitiven ekonomski dobiček. Višja taksa za emisije CO2 povečuje trajnostni vidik iz ekonomskega vidika, vendar pa so pri proizvodnji biogoriv te dokaj majhne. Okoljski dobiček je minimalen ali negativen zaradi majhnih emisij CO2.

Title:MULTI-CRITERIA OPTIMIZATION OF BIOPROCESSES USING SUSTAINABILITY METRIC AT ECONOMIC LEVEL
Abstract:The thesis contains optimization of bioprocesses, production of biodiesel and biogas, for which three aspects, economic, environmental and social, were taken into account. The purpose of the thesis was to study how individual criteria, economic (profit), environmental (taxes for CO2) and social (number of jobs), affect the combined sustainability criteria by different capacities for both bioprocesses. Optimisation was carried out in GAMS software. A sensitivity analysis was performed, where the following question was answered: At which capacity the processes should take place for the processes to become viable? Production of biofuels from the combined sustainability metric is sustainable. Only in the case of minimizing the environmental part, negative sustainability criterion is obtained. The reason is minimum amount of the produced raw materials, which reduces the economic profit. The social aspect is positive due to increased number of jobs. It is necessary to operate at large capacities in order to obtain positive economic profit. Higher tax for CO2 emissions increases sustainability aspect from an economic perspective, but by the production of biofuels emissions are relatively small. The environmental profit is minimal or negative, due to low CO2 emissions.
Keywords:biogas, biodiesel, sustainability metric, optimization
