| dc.description.abstract | Sustainable waste management is essential for environmental protection and climate change mitigation. In mainland Portugal, 59% of municipal waste was sent to landfills in 2023, while only 8% underwent organic valorization. Domestic composting offers low-cost, local solutions to reduce landfill dependency and promote a circular economy. When produced with quality, compost can be used in parks and gardens, improving soil structure, supplying nutrients for plants, and promoting water retention. This study describes the implementation of a composting program at a Higher Education Institution in Lisbon, focusing on community engagement, awareness-raising actions, process monitoring, and challenges faced. The training sessions increased the participants' knowledge, who reported personal constraints in urban areas, such as limited space and slow composting rates. The results from the composting assays showed that the temperature and the pH followed the expected patterns, with the pH ranging from 4 to 9. Although the composting process progressed satisfactorily, the maximum temperature reached was approximately 45 degrees C, a value that can occur in home composting systems. The compost analysis showed a mature compost with pH values around 8, a dark color, and an earthy smell, proper for use. Nonetheless, challenges remain, including contaminants found in some composters and the need for increased community participation and awareness to fully engage all stakeholders. | eng |
