The major concerns that mankind faces today are limited reserves of conventional energy, growing energy demand, and environmental pollution. This study depicts a comparative analysis done for the life cycle assessment of the biogas-based plant and coal-based plant designed for Bikaji Foods International Ltd., India. OpenLCA version 1.11.0 software was used with the database ecoinvent 3.3 LCIA methods (ReCiPe Midpoint H) to analyze the environmental impact and investigate the effect of the biogas-based plant and the coal-based plant. The functional unit of 1 MJ of energy generated from biogas and coal was selected to represent the results of the production of 15,271,600 MJ of energy. The results for marine eutrophication, particulate matter formation, photochemical oxidant formation and terrestrial acidification for the biogas-based plant were 734.527 kg N-Eq, 6314.012 kg PM-Eq, 1328.629 kg NMVOC and 3.933E04 kg SO-Eq, respectively. Whereas, for coal-based plant, these values were 4919.442 kg N-Eq, 1.962E04 kg PM-Eq, 6486.987 kg NMVOC and 13.448E04 kg SO-Eq, respectively. The greenhouse gas emissions and fossil depletion from the biogas-based plant were found negligible as compared to the coal-based plant. Overall, it was found that the biogas-based plant has a more remunerative impact on the environment than the coal-based plant. This study recommends that local authorities and industrial communities should invest more and more in increasing the number of biogas plants at domestic as well as commercial levels and secure a clean and green future for coming generations.
当今人类面临的主要问题是传统能源储备有限、能源需求不断增长以及环境污染。本研究对印度比卡吉食品国际有限公司设计的沼气发电厂和燃煤发电厂进行了生命周期评估的比较分析。使用OpenLCA 1.11.0版本软件和ecoinvent 3.3生命周期影响评价方法（ReCiPe中点H）来分析环境影响，并研究沼气发电厂和燃煤发电厂的效果。选择从沼气和煤炭产生的1兆焦能量作为功能单位，以代表生产15,271,600兆焦能量的结果。沼气发电厂的海洋富营养化、颗粒物形成、光化学氧化剂形成和陆地酸化的结果分别为734.527千克氮当量、6314.012千克颗粒物当量、1328.629千克非甲烷挥发性有机物和3.933×10⁴千克硫当量。而对于燃煤发电厂，这些值分别为4919.442千克氮当量、1.962×10⁴千克颗粒物当量、6486.987千克非甲烷挥发性有机物和13.448×10⁴千克硫当量。与燃煤发电厂相比，沼气发电厂的温室气体排放和化石能源消耗可忽略不计。总体而言，发现沼气发电厂对环境的影响比燃煤发电厂更有益。本研究建议地方当局和工业社区应在国内和商业层面加大对增加沼气发电厂数量的投资，为子孙后代确保一个清洁和绿色的未来。
