This research is not only essential in advancing the understanding of brownfield redevelopment but also serves as a guideline for revitalizing landfill sites for Davao City into sustainable, educational, and community-driven hubs. This study has intensive implications for landfill closure benchmarking, guiding for designing spaces within capped landfills, fostering ecotourism, education, and sustainable livelihoods. By implementing architectural innovation through the facilities within its solid waste management complex such as the materials recovery facility, recycling center, and composting facility, the project will be at its best in managing the solid waste of the city, addressing the pressing issue of pollution stemming from inadequate waste management practices.
