“…This research on CO2 bio-fixation and wastewater treatment can provide additional insights for mitigating the impact of climate change. Moreover, the conversion of microalgae biomass from the bio-fixation process into biofuels can serve as an alternative renewable energy source, thereby reducing the severity of climate change [28]. The novelty of this study lies in its LCA and techno-economic analysis of the integrated CO2 bio-fixation and the utilization of wastewater for nutrition by microalgae.…”

Technologies have been developed to reduce CO2 emissions, including CO2 bio-fixation by microalgae. This study evaluates carbon reduction by integrating milk factory wastewater treatment with microalgal biomass production, including its sustainability aspects through life cycle assessment (LCA) and techno-economic assessment (TEA). The microalgae species used were a consortium of Chlorella sp. and Scenedesmus sp. Five levels of carbon dioxide were provided to microalgae cultures: 0%, 5.5%, 6.2%, 8.1%, and 10.3%. Observed variables included CO2 uptake, absorption efficiency, and microalgal biomass production. The results showed that the CO2 sequestration efficiency by indigenous microalgae reached 0%, 9.2%, 98.8%, 96.2%, and 93.2% with average CO2 level loadings of 0%, 5.2%, 6.2%, 8.1%, and 10.3%, respectively. Chlorella sp. exhibited greater tolerance to high levels of CO2 concentration than Scenedesmus sp. TEA analysis revealed that CO2 bio-fixation and wastewater utilization significantly increased microalgal biomass production while also reducing environmental pollution. Furthermore, LCA indicated that the initial biomass production method (scenarios 1 and 2) had a higher environmental impact than the advanced method using wastewater treatment (scenarios 3 and 4). In conclusion, coupling microalgaebased wastewater treatment with CO2 bio-fixation offers promise for CO2 mitigation, enhanced biomass production, and reduced operational costs.

This study seeks to investigate the concept of combining coal power, concentrated solar power (CSP), as well as atmospheric pollutant (CO2) capture and storage (CCS) techniques in order to lower the emissions of carbon in electrical networks. Using concentrated solar energy, the study intends to absorb CO2 from the environment and coal-fired power plants and utilise it to grow microalgae in raceway ponds. The paper advocated the generation of microalgae using captured CO2 and included mathematical and experimental studies for carbon capture and sequestration from coal power plants. The study also provided information on the energy incident on the Scheffler dish, the typical steam temperature, the plant's efficiency in capturing carbon, and the total amount of CO2 released over time. The analysis comes to the conclusion that the system has the potential to remove 394200 kg of carbon dioxide annually and that improving the solar concentrator's design and operation can increase both the output and efficiency of the power generation system
