A continuous increase in the amount of greenhouse gases (GHGs) is causing serious threats to the environment and life on the earth, and CO₂ is one of the major candidates. Reducing the excess CO₂ by converting into industrial products could be beneficial for the environment and also boost up industrial growth. In particular, the conversion of CO₂ into methanol is very beneficial as it is cheaper to produce from biomass, less inflammable, and advantageous to many industries. Application of various plants, algae, and microbial enzymes to recycle the CO₂ and using these enzymes separately along with CO₂-phillic materials and chemicals can be a sustainable solution to reduce the global carbon footprint. Materials such as MOFs, porphyrins, and nanomaterials are also used widely for CO₂ absorption and conversion into methanol. Thus, a combination of enzymes and materials which convert the CO₂ into methanol could energize the CO₂ utilization. The CO₂ to methanol conversion utilizes carbon better than the conventional syngas and the reaction yields fewer by-products. The methanol produced can further be utilized as a clean-burning fuel, in pharmaceuticals, automobiles and as a general solvent in various industries etc. This makes methanol an ideal fuel in comparison to the conventional petroleum-based ones and it is advantageous for a safer and cleaner environment. In this review article, various aspects of the circular economy with the present scenario of environmental crisis will also be considered for large-scale sustainable biorefinery of methanol production from atmospheric CO₂.

温室气体（GHG）数量的持续增加对地球的环境和生命造成严重威胁，而CO ₂是主要的候选物质之一。通过转化为工业产品减少过量的CO ₂可能对环境有利，也可以促进工业增长。特别地，将CO ₂转化为甲醇是非常有益的，因为它由生物质生产便宜，易燃，并且对许多行业有利。应用各种植物，藻类和微生物酶回收CO ₂，并将这些酶与CO ₂分开使用-亲爱的材料和化学药品可以作为减少全球碳足迹的可持续解决方案。MOF，卟啉和纳米材料等材料也广泛用于CO ₂吸收和转化为甲醇。因此，将CO ₂转化为甲醇的酶和物质的组合可以激发CO _2的利用。与传统的合成气相比，CO ₂转化为甲醇的碳利用率更高，并且反应产生的副产物更少。产生的甲醇还可以用作清洁燃烧的燃料，在制药，汽车中以及在各种行业中用作通用溶剂等。。与常规的石油基燃料相比，这使甲醇成为理想的燃料，并且对于更安全，更清洁的环境而言是有利的。在这篇综述文章中，对于大气CO ₂大规模生产甲醇的可持续生物炼制厂，还将考虑当前环境危机情景下循环经济的各个方面。
