Abstract
En 中文
• Biocomposite substitution reduced window-frame GWP by up to 40% and fossil depletion by up to 45%. • Aluminum was identified as the dominant environmental hotspot in the baseline window design. • Component-level substitutions supported circular design through lightweighting (66% mass reduction), material efficiency, and recycled material use. • Sensitivity analyses confirmed the robustness of the results under alternative material sourcing and end-of-life scenarios.
