Sustainable sanitation is critical for environmental health, particularly in areas with limited water resources. This case study from Paraguay explores the effectiveness of composting latrines as a sustainable sanitation solution. These latrines offer a water-free alternative, yet the internal decomposition process and its influencing factors require further investigation.

Field research in Paraguay involved detailed temperature measurements within a composting latrine over several months. The study also included frequent mixing and moisturizing of the compost. The results revealed a consistent correlation between ambient temperatures, mixing, and the addition of liquids, which led to temperature increases. Seasonal temperature variations significantly influenced the rate and duration of these increases.

Despite these positive findings, the compost only reached pathogen destruction levels in 10% of the measurements. Therefore, the research underscores the importance of adhering to the World Health Organization's recommended storage times for complete pathogen elimination. If these storage durations are achievable, composting latrines provide an economically viable and sustainable sanitation option, conserving valuable water resources.
