Conventional building materials (CBMs) made from non-renewable resources are the main source of indoor air contaminants, whose impact can extend from indoors to outdoors. Given their sustainable development (SD) prospect, green building materials (GBMs) with non-toxic, natural, and organic compounds have the potential to reduce their overall impacts on environmental and human health. In this regard, biocomposites as GBMs are environmentally friendly, safe, and recyclable materials and their replacement of CBMs reduces environmental impacts and human health concerns. This study aims to develop a model of fully hybrid bio-based biocomposite as non-structural GBMs and compare it with fully petroleum-based composite in terms of volatile organic compound (VOC) emissions and human health impacts. Using a small chamber test (American Society for Testing and Materials (ASTM)-D5116) for VOC investigation and SimaPro software modeling with the ReCiPe method for evaluating human health impacts. Life cycle assessment (LCA) methodology is used, and the results indicate that switching the fully hybrid bio-based biocomposite with the fully petroleum-based composite could reduce more than 50% impacts on human health in terms of indoor and outdoor. Our results indicate that the usage of biocomposite as GBMs can be an environmentally friendly solution for reducing the total indoor and outdoor impacts on human health.
传统的不可再生资源建筑材料是室内空气污染物的主要来源，其影响范围可从室内延伸到室外。鉴于其可持续发展前景，无毒、天然和有机化合物的绿色建筑材料有可能减少其对环境和人类健康的整体影响。在这方面，生物复合材料作为绿色建筑材料是环保、安全和可回收的材料，它们替代传统建筑材料可减少对环境的影响和对人类健康的关注。本研究旨在开发一种完全混合的生物基生物复合材料模型，作为非结构性绿色建筑材料，并将其与完全基于石油的复合材料在挥发性有机化合物（VOC）排放和人类健康影响方面进行比较。采用小室测试（美国材料试验协会（ASTM）-D5116）进行 VOC 研究，以及 SimaPro 软件采用 ReCiPe 方法进行人类健康影响建模。使用生命周期评估（LCA）方法，结果表明，用完全混合的生物基生物复合材料替代完全基于石油的复合材料，在室内和室外，可减少超过 50%的对人类健康的影响。我们的结果表明，将生物复合材料作为绿色建筑材料使用，可以为减少对人类健康的总室内和室外影响提供一种环保的解决方案。
