Abstract

Traditional building materials have some drawbacks in the construction industry, particularly in terms of greenhouse gas emissions and energy consumption. Biomaterials derived from renewable sources are a promising alternative, significantly reducing the greenhouse effect and enhancing energy efficiency. However, traditional materials still dominate the construction sector, and there is a lack of understanding among some policymakers and developers regarding biomaterials. Here, we review building biomaterials and their policies and life cycle assessment through case studies. Bio-based materials have the potential to reduce over 320,000 tons of carbon dioxide emissions by 2050. They also exhibit advantages like decreasing water absorption by 40%, reducing energy consumption by 8.7%, enhancing acoustic absorption by 6.7%, and improving mechanical properties. We summarize recent advancements in mycelial materials, bioconcrete, natural fibers, and fiber-reinforced composites. We also explore the contributions of nanotechnology and microalgae technology in enhancing biomaterials' thermal insulation and eco-friendliness.

建筑领域的生物材料技术和政策：综述

传统建筑材料在建筑业中存在一些弊端，尤其是在温室气体排放和能源消耗方面。从可再生资源中提取的生物材料是一种很有前途的替代品，可以显著减少温室效应，提高能源效率。然而，传统材料仍在建筑领域占据主导地位，一些政策制定者和开发人员对生物材料缺乏了解。在此，我们通过案例研究回顾了建筑生物材料及其政策和生命周期评估。到 2050 年，生物基材料有望减少超过 32 万吨的二氧化碳排放量。生物基材料还具有吸水率降低 40%、能耗降低 8.7%、吸音率提高 6.7%、机械性能改善等优势。我们总结了菌丝材料、生物混凝土、天然纤维和纤维增强复合材料的最新进展。我们还探讨了纳米技术和微藻技术在增强生物材料的隔热性和生态友好性方面的贡献。

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
