摘要：

碳达峰与碳中和战略目标是中国应对全球性气候变化、实现人类命运共同体、推动自身发展节能减排的自我加压和大国担当。为了实现“双碳”目标，本研究以某日产2万m3生物燃气实际工程为案例，利用生命周期评价(LCA)的方法对其进行环境影响评价，研究将整个生命周期分成3个阶段：原料的收集与预处理、中高温厌氧发酵和沼气资源利用三个阶段，建立了该沼气厌氧发酵工程的评价清单，结果表明此生物燃气工程的净产能可达2494064.6 kg/a，与传统煤炭发电相比较，其降低环境影响的能力为234.9038 kpt/a，减弱率为32.89%。说明其具有良好的产能效益和生态环境效益，基于国内外生物燃气产业发展的现状及“双碳”愿景下面临的机遇和挑战，说明中国未来生物燃气产业发展有巨大潜力。

Abstract:

The strategic goal of “peaking carbon emissions and achieving carbon neutrality” shows China's responsibility as a major country to address global climate change issue, and its commitment to realizing a community of shared future for mankind and accelerating the course of energy-saving and emission-reduction. This study took a project with a daily output of 20,000 cubic meters of biogas as a case and used the method of life cycle assessment (LCA) to evaluate its environmental impact. The study divided the entire life cycle into three stages: raw material collection and pretreatment, medium-high temperature anaerobic fermentation and biogas resource utilization, and established an evaluation list for the biogas anaerobic fermentation project. The results show that the net production capacity of this biogas project can reach 2494064.6 kg/a. Compared with traditional coal power generation, its ability to reduce environmental impact is 234.9038 kpt/a, and the reduction rate is 32.89%. The study proves that the biogas project has productivity benefits and environmental benefits. Based on the current development situation of the biogas industry at home and abroad, and the opportunities and challenges under the vision of “peaking carbon emissions and achieving carbon neutrality”, this study shows that China's future biogas industry has great potential for development.
