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.[N.
