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

Heavy metals in industrial wastewaters are posing a serious threat to the environment and human health. Microalgae increasingly being seen as potential solutions this problem they can remove pollutants through biosorption. This process offers certain advantages over other more traditional metal removal techniques it is simple, inexpensive, eco-friendly, be performed wide range of experimental conditions. Biosorption possible due unique complex structure microalgal cell wall. The variety functional groups on surface wall (such carboxyl or amino groups) act binding sites for heavy metals, thus removing them from environment. review focuses composition most commonly used microalgae shows role their biosorption process. also aims report models predict velocity capacities.
