Factors influencing collected quantities of municipal solid waste
Slavica Schuster, 2019, doktorska disertacija

Opis: The first part of the survey, using the survey (enclosed with the annexes), tried in various ways to identify samples and facts by which we could predict the amount of waste collected according to some social and economic indicators of all municipalities of the Republic of Slovenia. Data were collected through surveys to determine the way we work and think about the collection of waste and landfills. For my research I have selected the Republic of Slovenia and its 212 municipalities. It is precisely Slovenia that in many respects represents a bright spot in waste management and management. In the second part of the research we used statistical methods to find the factors that influence the increase of waste. From the results we have proved our hypotheses and one of the most important is how the average age of people influences the increase of waste. We did the research over a period of 6 years (2012-2017). Where, by comparison, we find that they do not change significantly in structure by age, but of course socio-economic indicators such as average age change. In the last section, we compared the growth of waste collected with GDP growth. We show that with the growth of GDP, the amount of waste collected also increases. The research is also based on the Republic of Slovenia and beyond. In the second part of the last survey we also included data for EU Member States (28 of them).

Anaerobic treatment of excess yeast and waste ethanol from alcohol free beer production for increase of renewable energy use in brewing industry
Goran Lukić, Mario Panjicko, Gregor Drago Zupančič, 2020, objavljeni znanstveni prispevek na konferenci

Opis: In the presented paper we have investigated how large quantities of excess yeast and periodical releases of waste ethanol influence the operation of the anaerobic treatment process in a UASB reactor. The process was tested in a pilot-scale reactor with a design organic load of 16.0 kg/m3/day of COD. Through various stages of the experiment, several possible scenarios were tested, excess yeast was added continuously with concentrations up to 3 vol. %, whereas waste ethanol was added in batches of up to 0.8 % of daily volume load several days a week. The intent was to test real conditions in the treatment process. The whole experiment lasted for 77 days, where the maximum organic load of 24.72 kg/m3/day was successfully achieved with no adverse effects on the efficiency of the reactor performance although it significantly surpassed the design load. The COD efficiency at maximum OLR was 83.1 %, whereas the average was 88.0 %. The average biogas production rate increased from 2,044 m3/m3/day to 4.927 m3/m3/day. The microbial community structure analysis showed significant shifts only in the archaeal community (25 – 30 %) as a good adaptation to the addition of substrates. Monitoring the model brewery in applying the addition of yeast and ethanol to the wastewater treatment showed a 110 % increase in biomethane production. The consequence of the increased biomethane production is that the natural gas substitute ratio could be increased from the current average of 10.7 % to potentially 20.1 %, which is a substantial step towards the goal of renewable energy use.
