Plastic production has been increasing at enormous rates. Particularly, the socioenvironmental problems resulting from the linear economy model have been widely discussed, especially regarding plastic pieces intended for single use and disposed improperly in the environment. Nonetheless, greenhouse gas emissions caused by inappropriate disposal or recycling and by the many production stages have not been discussed thoroughly. Regarding the manufacturing processes, carbon dioxide is produced mainly through heating of process streams and intrinsic chemical transformations, explaining why first-generation petrochemical industries are among the top five most greenhouse gas (GHG)-polluting businesses. Consequently, the plastics market must pursue full integration with the circular economy approach, promoting the simultaneous recycling of plastic wastes and sequestration and reuse of CO₂ through carbon capture and utilization (CCU) strategies, which can be employed for the manufacture of olefins (among other process streams) and reduction of fossil-fuel demands and environmental impacts. Considering the previous remarks, the present manuscript’s purpose is to provide a review regarding CO₂ emissions, capture, and utilization in the plastics industry. A detailed bibliometric review of both the scientific and the patent literature available is presented, including the description of key players and critical discussions and suggestions about the main technologies. As shown throughout the text, the number of documents has grown steadily, illustrating the increasing importance of CCU strategies in the field of plastics manufacture.

塑料循环经济中二氧化碳的捕集与再利用：回顾

塑料生产以惊人的速度增长。特别地，已经广泛讨论了由线性经济模型引起的社会环境问题，特别是关于打算一次性使用且在环境中放置不当的塑料件。但是，由于不适当的处置或回收以及许多生产阶段导致的温室气体排放尚未得到彻底讨论。关于制造工艺，二氧化碳主要是通过加热工艺物流和进行固有的化学转化而产生的，这解释了为什么第一代石化工业是温室气体（GHG）污染最严重的五个行业之一。因此，塑料市场必须追求与循环经济方式的完全融合，₂通过碳捕获和利用（CCU）策略，可用于制造烯烃（以及其他工艺流程）以及减少化石燃料需求和环境影响。考虑到先前的言论，本手稿的目的是对塑料行业中的CO ₂排放，捕获和利用进行回顾。本文提供了对现有科学文献和专利文献的详细文献计量学综述，包括关键参与者的描述以及有关主要技术的重要讨论和建议。如全文所示，文档数量在稳步增长，这说明了CCU策略在塑料制造领域的重要性日益提高。
