建筑固体废物（固废）资源化是建筑业高质量发展的必然要求，在“双碳”战略目标的驱动下进一步提升建筑固废资源化利用率迫在眉睫。废弃防水材料作为建筑固废的重要组成部分，其资源化研究基本处于空白状态。本文测算了 2005—2021年我国防水材料总产量（2.983×10¹⁰ m²）、防水卷材总产量（1.89×10¹⁰ m²），形成了防水材料资源化的主体是防水卷材资源化的基本判断。应对国家绿色低碳发展形势，提出了针对防水卷材的减量化、重复利用、循环再生（3R）资源化路径，防水卷材“基因组”、多尺度/多场景分析、机器学习预测相结合的高性能防水卷材研发理念，明晰了以体系拆解为核心的防水卷材重复利用模式、以“分类”“分级”“分解”为关键构成的废弃防水卷材循环再生策略。应以再生防水卷材为主攻方向，推动全再生防水卷材、增材制造技术的深入研究和创新应用。面向防水卷材资源化未来发展，“原料-产品”“产品-工程”是亟待攻克的关键环节，需要管理部门、学术界、工业界共同努力。

The reclamation of construction solid wastes is crucial for the high-quality development of the construction industry and it is urgent to further improve the utilization rate of the construction solid wastes to achieve the carbon peaking and carbon neutralization goals. Waste waterproof materials are an important component of the construction solid wastes; however, research on the utilization of these materials is almost blank in China. As calculated in this study, the total output of waterproof materials in China was 2.983×10¹⁰ m² during 2005‒2021 and that of waterproof membranes was 1.89×10¹⁰ m², indicating that waterproof membranes are the main body for waterproof material recycling. In response to the national green and low-carbon development situation, a utilization path for "reducing, reusing, and recycling" (3R) the waterproof membranes is proposed as well as a high-performance waterproof membrane research and development concept that combines waterproof membrane "genome", multi-scale / multi-scenario analysis, and machine learning prediction. A waterproof membrane reuse mode with system disassembly as the core is clarified as well as a recycling strategy with classification, gradation, and deconstruction as the core. Moreover, the in-depth research and innovative application of fully recycled waterproof membranes and additive manufacturing technology should be promoted. The transformation of recycled waterproof membranes to products and the engineering application of these products are major challenges to be addressed in the future, which requires joint efforts of the management departments, academia, and industry.
