Abstract This study analyzes end-of-life management gaps associated with phenolic foam insulation, a thermoset-based building insulation material, and proposes directions for developing management standards in Korea. Although phenolic foam is increasingly adopted due to its low thermal conductivity and favorable fire performance, its thermoset structure prevents melt-based recycling, and its acidic characteristics raise concerns regarding environmental impacts when disposed of without pretreatment. Through a document-based comparative analysis of construction and demolition waste management systems in the EU, Germany, and Japan, this study identifies structural regulatory gaps in Korea’s current framework. In particular, Korea broadly classifies insulation as synthetic resin waste without distinguishing thermoplastic and thermoset materials with fundamentally different disposal pathways, and lacks institutional mechanisms for material identification and source separation at the demolition stage. To address these gaps, this study proposes (1) the establishment of a dedicated classification code for thermoset insulation, (2) mandatory material identification through pre-demolition audits, (3) strengthened source separation requirements, and (4) the introduction of stabilization standards prior to controlled landfill disposal, supported by a phased implementation roadmap. This research contributes a management-system oriented framework for anticipatory policy development before large-scale phenolic foam waste generation occurs.
