dc.description.abstract | This study assesses the impact of a bioreactor composting technology developed by the Department of Science and Technology-Industrial Technology Development Institute (DOST-ITDI) and used in Marikina City, Philippines. Using the Multi-dimensional Sustainability Framework (MSF) and the Context, Input, Process, Product (CIPP) Model, it evaluated the environmental, economic, social, technological, and institutional effects of the bioreactor in managing organic waste in compliance with Republic Act No. 9003. Data were gathered through interviews and focus group discussion with Materials Recovery Facility (MRF) staff and secondary sources within the project area. Findings indicate that the bioreactor helps reduce landfill waste and greenhouse gas emissions, produces nutrient-rich compost that improves soil, and creates community jobs and involvement. While the technology expedites composting and reduces manual work, it faces challenges like machine wear and need for better support. The study suggests improving design, training, and monitoring. Overall, the bioreactor is a sustainable and effective solution for organic waste that benefits the environment, society, and economy while supporting national and global sustainability goals. | |
