Agrowaste sources can be utilized to produce biogas by anaerobic digestion reaction. Fossil fuels have damaged the environment, while the biogas rectifies the issues related to the environment and climate change problems. Techno-economic analysis of biogas production is followed by nutrient recycling, reducing the greenhouse gas level, biorefinery purpose, and global warming effect. In addition, biogas production is mediated by different metabolic reactions, the usage of different microorganisms, purification process, upgrading process and removal of CO₂ from the gas mixture techniques. This review focuses on pre-treatment, usage of waste, production methods and application besides summarizing recent advancements in biogas production. Economical, technical, environmental properties and factors affecting biogas production as well as the future perspective of bioenergy are highlighted in the review. Among all agro-industrial wastes, sugarcane straw produced 94% of the biogas. In the future, to overcome all the problems related to biogas production and modify the production process.
农业废弃物资源可通过厌氧消化反应用于生产沼气。化石燃料已经破坏了环境，而沼气则解决了与环境和气候变化问题相关的难题。对沼气生产进行技术经济分析之后是养分循环利用、降低温室气体水平、生物精炼目的以及全球变暖效应。此外，沼气生产由不同的代谢反应、不同微生物的使用、净化过程、升级过程以及从气体混合物中去除二氧化碳的技术介导。本综述除了总结沼气生产的最新进展外，还重点关注预处理、废弃物利用、生产方法及应用。综述中强调了影响沼气生产的经济、技术、环境特性和因素以及生物能源的未来前景。在所有农业工业废弃物中，甘蔗秸秆产生了94%的沼气。未来，要克服与沼气生产相关的所有问题并改进生产工艺。
