Abstract:V magistrskem delu smo raziskovali možnosti trajnostne uporabe odpadnega blata, ki nastaja v mesnopredelovalni industriji. Namen našega dela je preučiti alternativne metode ravnanja z odpadnim blatom, s posebnim poudarkom na procesu torefikacije, ki omogoča izboljšanje kurilne vrednosti in zmanjšanje vsebnosti vlage v materialu. V teoretičnem delu smo opisali delovanje čistilne naprave, iz katere smo pridobili vzorce, in proces torefikacije. Eksperimentalni del je vključeval termično obdelavo vzorcev pri različnih temperaturah in analizo njihovih fizikalnih ter kemijskih lastnosti. Ugotovili smo, da torefikacija znatno povečuje kurilno vrednost obeh vzorcev, "Sito" in "Flotat", pri čemer je toreficirano sito pri 350 °C doseglo najvišjo vrednost, toreficiran flotat pa pri 300 °C. Ugotovili smo tudi, da so toreficirani vzorci sita imeli višji masni delež fiksnega ogljika, medtem ko so toreficirani vzorci flotata imeli višji masni delež pepela, kar pojasni zakaj je imelo nižjo kurilno vrednost kot tudi razmerje goriv. Vsi dokazi strmijo k temu, da so toreficirani vzorci sita bolj primerni za kurjenje in za proizvodnjo energije kot toreficirani vzorci flotata. Glede adsorpcijskih sposobnosti pa smo ugotovili, da je material neprimeren za adsorpcijo fosfata, ker vzorci že vsebujejo fosfatne spojine, medtem ko je za adsorpcijo bakra je primeren. Iz vseh dobljenih rezultatov lahko z gotovostjo trdimo, da kot material za gorivo ter kot adsorbent za razne snovi, je sito toreficirano pri 350 °C, najbolj primerno za uporabo. Za flotat pa je najbolj primeren, ko je toreficiran pri 300 °C. Rezultati so pokazali, da toreficirano blato predstavlja obetaven vir energije in učinkovit adsorbent za onesnaževala, kot je baker. Raziskava prispeva k razvoju trajnostnih praks v mesnopredelovalni industriji in odpira možnosti za nadaljnje raziskave o uporabi odpadnega blata v različnih aplikacijah. S tem delom smo potrdili, da je učinkovito ravnanje z odpadnim blatom ključno za zmanjšanje okoljskega vpliva in povečanje energetske učinkovitosti.

Title:Analysis and application of waste sludge from meat processing industry
Abstract:In our master's thesis, we explored the possibilities for the sustainable use of waste sludge generated in the meat processing industry. The aim of our work was to investigate alternative methods for managing waste sludge, with a particular focus on the torrefaction process, which enhances the calorific value and reduces the moisture content of the material. In the theoretical part, we described the operation of the wastewater treatment plant from which we obtained samples, and the torrefaction process. The experimental part involved the thermal treatment of samples at various temperatures and the analysis of their physical and chemical properties. We found that torrefaction significantly increased the calorific value of both samples, "Sito" and "Flotat," with torrefied Sito reaching the highest value at 350°C and torrefied Flotat at 300°C. We also found that the torrefied samples of sito had a higher mass fraction of fixed carbon, while the torrefied samples of flotat had a higher mass fraction of ash. This explains why flotat had a lower calorific value as well as a lower fuel ratio. All evidence points to the fact that torrefied sito samples are more suitable for combustion and energy production compared to torrefied flotat samples. Regarding adsorption capabilities, we determined that the material is unsuitable for phosphate adsorption because the samples already contain phosphate compounds. However, it is suitable for copper adsorption. Based on all the results obtained, we can confidently conclude that as a fuel material and as an adsorbent for various substances, sito torrefied at 350°C is the most suitable for use. For flotat, the most suitable torrefaction temperature is 300°C. The results showed that torrefied sludge represents a promising energy source and an effective adsorbent for pollutants such as copper. Our research contributes to the development of sustainable practices in the meat processing industry and opens up possibilities for further research on the use of waste sludge in various applications. With this work, we confirmed that efficient waste sludge management is crucial for reducing environmental impact and increasing energy efficiency.
