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.

Globally, nations are trying to address environmental issues such as global warming and climate change, along with the burden of declining fossil fuel reserves. Furthermore, countries aim reach zero carbon emissions within existing rising energy crisis. Therefore, bio-based alternative sustainable feedstocks being explored for producing bioenergy. One renewable resource is microalgae; these photosynthetic microorganisms that grow on non-arable land, in extreme climatic conditions, have ability thrive even sea wastewater. Microalgae high efficiencies biomass productivity compared other terrestrial plants. Whole microalgae or their extracted metabolites can be converted various biofuels bioethanol, biodiesel, biocrude oil, pyrolytic bio-oil, biomethane, biohydrogen, bio jet fuel. However, several challenges still exist before faster broader commercial application a bioenergy feedstock biofuel production. Selection appropriate microalgal strains, development pre-concentrating techniques, utilization wet production, coupled an integrated biorefinery approach value-added products, could improve sustainability economic viability biofuel.

Throughout the years, experiments with membrane, electrochemical, biological and thermal technologies have been explored to recover resources from a range of wastewaters such as municipal, industrial, urine sewage sludge. However, multiple resource recoveries at commercial pilot scale are still lacking, instead, focusing on specialising recovery narrow set products. Herein, divergence across municipal industrial wastewater streams – nutrients energy for municipal; heavy metals water streams; material seen both was observed through literature review. This review aims provide perspective academic professionals alike current available their emerging trends tie in these circular economics. Consequently, high sludge transportation costs may pressure treatment plants (WWTPs) adopt value-adding, onsite transforming centralised decentralised WWTPs into facilities.
