Microalgal biomass is a renewable energy source and is considered as a crucial solution in the increasing energy demand and greenhouse gas emissions. Through various thermochemical conversion processes such as torrefaction, pyrolysis, liquefaction, and gasification, biomass can be converted to different bioenergy products. However, the production of these bioenergy products through the aforesaid thermochemical processes entails raw material consumption, energy consumption, and environmental impact. A multitude of studies has been conducted to evaluate the environmental impact of bioenergy products for specific thermochemical processes on a specific biomass feedstock using life cycle assessment. This study aims to comprehensively review the life cycle assessment of bioenergy products from microalgal biomass together with lignocellulosic biomass and through different thermochemical processes. The study identifies the current challenges and potential future works of bioenergy production from different thermochemical processes in the perspective of a life cycle assessment framework.
微藻生物质是一种可再生能源，被认为是解决能源需求增长和温室气体排放的关键方案。通过热化学转化过程，如干馏、热解、液化和气化，生物质可以转化为不同的生物能源产品。然而，通过上述热化学过程生产这些生物能源产品需要消耗原材料、能源并产生环境影响。已经有大量研究通过生命周期评估来评估特定热化学过程中特定生物质原料的生物能源产品的环境影响。本研究旨在全面回顾微藻生物质以及木质纤维素生物质通过不同热化学过程生产生物能源产品的生命周期评估。本研究从生命周期评估框架的角度确定了不同热化学过程生物能源生产的当前挑战和潜在未来工作。
