Abstract

Magistrsko delo analizira okoljske vplive različnih tehnologij čiščenja odpadnih voda in načinov upravljanja v planinskih kočah s poudarkom na Koči pri Triglavskih jezerih, priljubljeni turistični destinaciji, ki se sooča z izzivi prekomernega vnosa hranil v bližnje Dvojno jezero. Z metodo analize življenjskega cikla (LCA) smo ovrednotili dva predlagana scenarija v primerjavi s sedanjim nepravilno delujočim sistemom čiščenja odpadnih voda. Upoštevali smo kategorije vplivov, kot so globalno segrevanje, poraba vode, evtrofikacija sladke vode, ekotoksičnost sladke vode in izraba fosilnih virov. Pri Scenariju I je predviden sodoben membranski filter, medtem ko so v scenariju II vključene robustne tehnologije, kot so suha stranišča in ratlinske čistilne naprave (RČN). Rezultati LCA so pokazali, da ima scenarij II manjši vpliv na okolje v vseh kategorijah vplivov, zlasti pri izrabi fosilnih goriv, kjer je vpliv scenarija I 25-krat večji od vpliva scenarija II. Analiza je pokazala pomen izbire materialov, saj so solarni paneli v scenariju I prispevali skoraj 60 % celotnega vpliva na sladkovodno ekotoksičnost v fazi gradnje. V obeh scenarijih imajo na okoljski odtis ključno vlogo puhala. Oba scenarija pozitivno vplivata na kategorijo vpliva porabe vode, kot posledica ponovne uporabe vode in uporabe suhih stranišč. Pri Scenariju II je velik pozitivni vpliv prihranka vode zmanjšal celoten okoljski vpliv sistema. Analiza je pokazala, da se je pri optimizaciji ravnanja z odpadnimi vodami v gorskih kočah potrebno osredotočiti na robustne tehnologije z minimalnimi potrebami po energiji. Po zgledu švicarskih koč, kjer se vse bolj uveljavlja vgradnja suhih stranišč in drugih energetsko učinkovitih rešitev, rezultati predlagajo podoben premik tudi za slovenske planinske koče.

Secondary title: Evaluation of solutions for wastewater management in mountain huts using the LCA method
Secondary abstract: Master's thesis analyses the environmental impacts of different wastewater treatment technologies and management methods in mountain huts, focusing on the Triglav Lakes Hut, a popular tourist destination facing organic and nutrient pollution in the nearby Double Lake. Using Life Cycle Assessment (LCA), we evaluated two proposed scenarios against the current malfunctioning wastewater treatment system. We considered impact categories such as global warming, water consumption, freshwater eutrophication, freshwater ecotoxicity, and fossil resource scarcity. Scenario I include a modern membrane filter, while Scenario II include robust technologies such as dry composting toilets and constructed wetlands (CW). The LCA results showed that Scenario II had a lower environmental impact in all impact categories, particularly in the scarcity of fossil resources, where the impact of Scenario I is 25 times higher than Scenario II's. The analysis showed the importance of material choices, with solar panels in Scenario I contributing almost 60% of the total impact on freshwater ecotoxicity in the construction phase. In both scenarios, blowers play a vital role in the environmental footprint. Both systems positively impact the water consumption impact category due to water reuse and dry toilets. In Scenario II, the significant positive impact of water savings reduced the overall environmental impact of the system. The analysis shows that optimising wastewater management in mountain huts should focus on robust technologies with minimal energy requirements. Following the example of Swiss huts, where the installation of dry toilets and other energy-efficient solutions is gaining popularity, the results suggest a similar shift for Slovenian mountain huts.
