Biochar is a carbonaceous material, which can be decorated with metals, that has been garnering attention to be used in the treatment of water due to its contribution to waste management and circular economy. This study presents the life cycle assessment (LCA) regarding the generation of raw biochar and its modification with iron (Fe-modified biochar). SimaPro 9.3.0.3 software was used to simulate the environmental impacts of both carbonaceous materials. The potential environmental effects obtained from the production of raw biochar were mainly ascribed to the source of energy utilized during this process. The potential impacts demonstrated that the generation of gases and polycyclic aromatic hydrocarbons are the main concern. In the case of Fe-modified biochar, the potential environmental effects differed only in the stage of the biomass modification with the metal. These effects are associated with the extraction of Fe and the generation of wastewater. These findings provide an insight into the environmental effects linked to the production of raw and Fe-modified biochar. However, further LCA research should be performed concerning other materials and compounds than can be generated during the biomass thermochemical conversion.
生物炭是一种含碳材料，可进行金属修饰，因其对废物管理和循环经济的贡献，在水处理中受到关注。本研究介绍了关于原生生物炭生成及其铁改性（铁改性生物炭）的生命周期评估（LCA）。使用SimaPro 9.3.0.3软件模拟了这两种含碳材料的环境影响。原生生物炭生产产生的潜在环境影响主要归因于该过程中使用的能源来源。潜在影响表明，气体和多环芳烃的产生是主要关注点。对于铁改性生物炭，潜在环境影响仅在生物质金属改性阶段有所不同。这些影响与铁的提取和废水的产生有关。这些发现提供了对与原生和铁改性生物炭生产相关的环境影响的见解。然而，对于生物质热化学转化过程中可能产生的其他材料和化合物，应开展进一步的生命周期评估研究。
