Abstract
- Due to large number of doors used housing and construction products, the greenhouse gas (GHG) footprint related to door manufacturing is an interesting topic. Timber and bamboo products can reduce GHG emission due to their biogenic carbon storage via photosynthesis. The scientific evidence on the climate impact using wood-based door (WBD) and bamboo-based door (BBD) to replace steel-based door (SBD) is limited. In this study, life cycle assessments for WBD, BBD, SBD were conducted to evaluate the carbon impacts of raw materials, production, transport, and end-of-life stages. The GHG footprint of WBD, BBD, and SBD ranged from 270.42 to 363.24, 285.31–398.31, and 983.8–986.76 kg CO 2 e/m3, respectively, indicating that the bio-based doors exhibited lower energy consumption and GHG emissions. The raw material stage (484.78–569.34 kg CO 2 e/m3) was identified as a major source of GHG emissions throughout the product life cycle, while hot-pressing and coating processes were identified as emission hotspots in the production stage. Regarding biogenic carbon storage, the use of bio-based materials instead of steel-based materials for fire door manufacturing significantly reduced emissions. Considering disposal methods, recycling and incineration should be prioritized over landfills. Future research should focus on field survey in raw material stage, along with conducting a technical and economic analysis. The results provide valuable guidance for selecting doors in China in term of biogenic carbon storage and resource protection. [Display omitted] • GHG footprint of WBD and BBD ranged from 270.42 to 398.31 kg CO 2 e/m3. • Risk-relevance in GHG emissions of fire doors can be assessed using risk fraction. • Bio-based solution is preferrable over steel-based materials for fire doors. • Recycling and incineration should be favored over landfills. • The most influential mitigation method and future research directions are proposed.
