“…More land is required to fulfil the massive demand for biomass and convert forests and grasslands to arable lands. This transformation of forests and grassland to an arable field releases CO 2 into the atmosphere [349,350]. Thus, biocapturing CO 2 from the environment is another valuable strategy to recover value-added products [349].…”

In the late twentieth century, the only cost-effective opportunity for waste removal cost at least several thousand dollars, but nowadays, a lot of improvement has occurred. The biomass and waste generation problems attracted concerned authorities to identify and provide environmentally friendly sustainable solutions that possess environmental and economic benefits. The present study emphasises the valorisation of biomass and waste produced by domestic and industrial sectors. Therefore, substantial research is ongoing to replace the traditional treatment methods that potentially acquire less detrimental effects. Synthetic biology can be a unique platform that invites all the relevant characters for designing and assembling an efficient program that could be useful to handle the increasing threat for human beings. In the future, these engineered methods will not only revolutionise our lives but practically lead us to get cheaper biofuels, producing bioenergy, pharmaceutics, and various biochemicals. The bioaugmentation approach concomitant with microbial fuel cells (MFC) is an example that is used to produce electricity from municipal waste, which is directly associated with the loading of waste. Beyond the traditional opportunities, herein, we have spotlighted the new advances in pertinent technology closely related to production and reduction approaches. Various integrated modern techniques and aspects related to the industrial sector are also discussed with suitable examples, including green energy and other industrially relevant products. However, many problems persist in present-day technology that requires essential efforts to handle thoroughly because significant valorisation of biomass and waste involves integrated methods for timely detection, classification, and separation. We reviewed and proposed the anticipated dispensation methods to overcome the growing stream of biomass and waste at a distinct and organisational scale.

“…As a solution to beat these consequences, there is growing interest in developing alternatives for CO 2 capture, including photosynthetic microorganisms (Aghaalipour et al 2020). Microalgae cultivation has proposed as a highly promising biological method of CO 2 because the generated biomass can be used widely (Rodas-Zuluaga et al 2021). Microalgae biomass have become an eco-friendly alternative in emerging industrial sectors such as aquaculture and animal feed, human nutrition, cosmetics, biofertilizers, and biofuels (Chisti 2008;Acién et al 2017).…”

Photo-respirometric tecniques are applied for evaluating photosynthetic activity in phototrophic organisms. These methods allow to evaluate photosynthetic response under different conditions. In this work, the influence of nutrient availability (nitrate, ammonium, and phosphate) on the photosynthesis and respiration of Scenedesmus almeriensis was studied using short photo-respirometric measurements. Both photosynthesis and respiration increasing until saturation value and consecutively diminishing, presenting inhibition by high concentrations. Regarding the influence of phosphorus concentration in microalgae cells, a similar hyperbolic trend was observed but no inhibition was observed at high concentration. Based on these experimental data, the respiration, and the photosynthesis rate of S. almeriensis were modelled using Haldane equation for nitrate and ammonium data, and Monod equation for phosphate data. In addition, experiments were performed to determine the yield coefficients for both nitrogen and phosphorus in S. almeriensis cultures. The data showed that the nitrogen and phosphorous coefficient yields are not constant, being modified as a function of nutrients concentration, presenting the luxury uptake phenomena. Finally, the proposed models were incorporated into a simulation tool to evaluate the photosynthetic activity and the nutrient yield coefficients of S. almeriensis when different culture media and wastewaters are used as a nitrogen and phosphorous source for its growth.Key points• Microalgal photosynthesis/respiration vary as a function of nutrients availability.• Photosynthesis inhibition appears at high N-NO3-and N-NH4+concentrations.• Nutrient yield coefficients are influenced by luxury uptake phenomenon.

Global warming caused by carbon dioxide (CO2) emissions is one of the most important topics of concern in the fields of science, environment and global economy. Carbon dioxide emissions have increased dramatically in recent years, and this trend is likely to continue with a projected increase of both global energy consumption and CO2 emissions by 51% in 2050 compared with 2005. To mitigate the negative impacts arising, a potential strategy to convert CO2 into renewable fuels or valuable chemicals can be applied. Bio‐CO2 emission reduction is receiving more and more attention as an environmentally friendly method. Microalgae are attracting worldwide attention in this regard owing to their exceptional speed of growth, resistance to harsh environments and low production costs. In this review, the biochemical principles of microalgae‐CO2 fixation and the research progress of microalgae strains used for CO2 fixation are reviewed and discussed. The latest progress in the co‐development of a microalgae carbon sequestration industry and other industries are provided, along with a survey of the progress in methods to improve microalgae‐CO2 fixation. Finally, the problems to be solved in the industry and its future directions of development are clarified. © 2021 Society of Chemical Industry (SCI).
