Advances in Constructional Engineering

Plant fiber reinforced composites (PFRC) have significant application potential in the field of temporary buildings due to their characteristics of light weight, high strength, and renewability. Aiming at the problems of frequent demolition and reconstruction of temporary buildings, material waste, and environmental pressure, this paper proposes a recycling scheme based on life cycle management, which systematically discusses aspects such as material recycling, performance regeneration, structural redesign, and industrial chain connection. By establishing a hierarchical recycling system, optimizing fiber processing technology, and introducing detachable structural design, the reuse rate of materials and structural safety can be significantly improved. Combined with practical engineering cases, the feasibility and advantages of this scheme in reducing carbon emissions, minimizing construction waste, and enhancing economic benefits are verified, providing an operable technical path and management model for the green and sustainable development of temporary buildings.
