Interest in animal cell-based meat (ACBM) as an environmentally conscious replacement for livestock production has been increasing; however, a life cycle assessment (LCA) for the existing production methods of ACBM has not been conducted. Currently, ACBM products are being produced at a small scale, but ACBM companies are intending to scale-up production. Updated findings from recent technoeconomic assessments (TEAs) of ACBM were utilized to perform an LCA of near-term ACBM production. A scenario analysis was conducted utilizing the metabolic requirements examined in the TEAs of ACBM, and a purification factor was utilized to account for growth medium component processing. The results indicate that the environmental impact of near-term ACBM production has the potential to be significantly higher than beef if a highly refined growth medium is utilized for ACBM production. This study highlights the need to develop a sustainable animal cell growth medium that is optimized for high-density animal cell proliferation for ACBM to generate positive economic and environmental benefits.
对基于动物细胞的肉类(ACBM)作为一种具有环境意识的牲畜生产替代品的兴趣一直在增加;然而,尚未对ACBM现有生产方法进行生命周期评估(LCA)。目前,ACBM产品正在小规模生产,但ACBM公司打算扩大生产规模。利用最近对ACBM的技术经济评估(TEA)的最新结果,对近期ACBM生产进行了LCA。利用ACBM的TEA中研究的代谢需求进行了情景分析,并使用净化因子来考虑生长培养基成分的处理。结果表明,如果将高度精制的生长培养基用于ACBM生产,近期ACBM生产对环境的影响可能会显著高于牛肉。本研究强调,需要开发一种可持续的动物细胞生长培养基,该培养基针对ACBM的高密度动物细胞增殖进行了优化,以产生积极的经济和环境效益。
