The green transition requires renewable energy resources, especially the role of biomass is very crucial as it promotes resource circularity if sustainable substrates are used. This mini-review focuses on green gas derived from biomass called biomethane, which appears to be strategic in the face of soaring energy costs. Hence, combined Strengths, Weaknesses, Opportunities and Threats-Analytic Hierarchy Process analysis is used to compare and evaluate the critical factors. The results provide not only methodological insights through the application of the local-global priority method, but also managerial insights that see biomethane as a winning element for the green transition, fighting climate change and reducing dependence on external energy sources. Subsidies have played a key role in pursuing economic sustainability; however, their use should be reduced over time and measured to the actual contribution related to environmental and social improvement. The results of this work highlight that biomethane development is important to tackle climate change and to be self-sufficient from an energy perspective. This development plan, based on circularity of resources, includes subsidies for small-scale plants, substrates from neighbouring territories, citizen involvement in decision-making processes, valorization of suitable waste from an environmental perspective and stability of political choices.
绿色转型需要可再生能源，特别是生物质的作用非常关键，因为如果使用可持续的基质，它可以促进资源循环利用。这篇小型综述聚焦于源自生物质的绿色气体，即生物甲烷，它在能源成本飙升的情况下似乎具有战略意义。因此，我们使用优势、劣势、机会和威胁（AHP）分析方法来比较和评估关键因素。结果不仅通过应用局部-全局优先级方法提供了方法上的见解，还从管理角度来看待生物甲烷作为绿色转型、应对气候变化和减少对外源能源依赖的制胜因素。补贴在追求经济可持续性方面发挥了关键作用；然而，随着时间的推移，应该减少其使用，并根据实际贡献来衡量与环境和社会改善相关的补贴。这项工作的结果强调了生物甲烷开发对于应对气候变化和从能源角度实现自给自足的重要性。这种基于资源循环利用的发展计划包括为小型工厂提供补贴、从邻近地区获取基质、公民参与决策过程、从环境角度对合适废物进行增值利用以及政治选择的稳定性。
