“…During the microalgae-bacteria consortium treatment processes a greenhouse gas emission rate is lowering, because the ma-jority of N is assimilated by the microalgae-bacteria consortium instead of being converted to oxides of nitrogen [34]. The algae could be used for water and wastewater treatment, as feedstock for producing biofuels, food, cosmetics, pharmaceuticals, fertilizers and also could be used as feed for animals [35].…”

Since sources of clean water are limited, industrial wastewaters are available and utilization of biomass as a renewable energy source is increasing; therefore, wastewater could be used as a growth medium for the production of biomass. Such an approach is directly connected to the sustainable circular bioeconomy. The main aim of the present study was to evaluate the potential application of industrial wastewater for cultivation of C. vulgaris and S. armatus. This study was carried out in order to: (i) assess the influence of wastewater on the activity of microalgae; (ii) assess batch and repeated fed-batch culture cultivation techniques; and (iii) assess cultivation of microalgae in suspension and immobilized on alginate beads. It was demonstrated that microalgae can be cultivated in wastewater contaminated with inorganic and organic chemical compounds in autotrophic conditions, batch culture or repeated fed-batch culture, and also in the form of suspension as well as being immobilized on alginate beads. The growth rate of microalgae in samples with initial algal culture concentrations of 100 g/L was as follow: 2.3 ± 0.01 d−1–3.8 ± 0.03 d−1 for C. vulgaris and 2.2 ± 0.02 d−1–4.0 ± 0.06 d−1 for S. armatus. In samples with initial algal culture concentrations of 50 g/L the growth rate of microalgae (μ) was as follow: 1.2 ± 0.01 d−1–2.2 ± 0.02 d−1 for C. vulgaris and 1.3 ± 0.02 d−1–2.4 ± 0.05 d−1 for S. armatus. Cultivation of microalgae in industrial wastewater has more advantages than cultivation carried out in clean water due to lower costs and protection of natural resources.

“…However, their increased building costs make them unlikely to offer a competitive advantage in lower‐priced nations (Maroušek et al, 2023). Producing 1 ton of dry algae biomass was estimated to be 500 and 110 USD for the PBRs and open pond, respectively, considering the price of CO 2 capture when integrated into biomass production, which was 250 and 55 USD for the photobioreactor and open pond, respectively (Zabochnicka et al, 2022).…”

Environmental pollution is a big challenge that has been faced by humans in contemporary life. In this context, fossil fuel, cement production, and plastic waste pose a direct threat to the environment and biodiversity. One of the prominent solutions is the use of renewable sources, and different organisms to valorize wastes into green energy and bioplastics such as polylactic acid. Chlorella vulgaris, a microalgae, is a promising candidate to resolve these issues due to its ease of cultivation, fast growth, carbon dioxide uptake, and oxygen production during its growth on wastewater along with biofuels, and other productions. Thus, in this article, we focused on the potential of Chlorella vulgaris to be used in wastewater treatment, biohydrogen, biocement, biopolymer, food additives, and preservation, biodiesel which is seen to be the most promising for industrial scale, and related biorefineries with the most recent applications with a brief review of Chlorella and polylactic acid market size to realize the technical/nontechnical reasons behind the cost and obstacles that hinder the industrial production for the mentioned applications. We believe that our findings are important for those who are interested in scientific/financial research about microalgae.

“…CO 2 could be captured during absorption, cryogenic distillation, membrane-based separation, adsorption, etc. Many inorganic or organic sorbents could be used for carbon capture and post-process wastes could be used as materials for other technologies [ 4 ]. The Lithuanian company INECO has patented an FFH sorbent designed to remove contaminants from wastewater [ 5 ].…”

Biochar enriched with metals has an increased potential for sorption of organic and inorganic pollutants. The aim of the research was to identify the possibility of using biochar composites produced on the basis of waste plant biomass and waste FFH (ferryferrohydrosol) containing iron atoms, after CO2 capture. The composites were produced in a one-stage or two-stage pyrolysis process. Their selected properties were determined as follows: pH, ash content, C, H, N, O, specific surface area, microstructure and the presence of surface functional groups. The produced biochar and composites had different properties resulting from the production method and the additive used. The results of experiments on the removal of methylene blue (MB) from solutions allowed us to rank the adsorbents used according to the maximum dye removal value achieved as follows: BC1 (94.99%), B (84.61%), BC2 (84.09%), BC3 (83.23%) and BC4 (83.23%). In terms of maximum amoxicillin removal efficiency, the ranking is as follows: BC1 (55.49%), BC3 (23.51%), BC2 (18.13%), B (13.50%) and BC4 (5.98%). The maximum efficiency of diclofenac removal was demonstrated by adsorbents BC1 (98.71), BC3 (87.08%), BC4 (74.20%), B (36.70%) and BC2 (30.40%). The most effective removal of metals Zn, Pb and Cd from the solution was demonstrated by BC1 and BC3 composites. The final concentration of the tested metals after sorption using these composites was less than 1% of the initial concentration. The highest increase in biomass on prepared substrates was recorded for the BC5 composite. It was higher by 90% and 54% (for doses of 30 g and 15 g, respectively) in relation to the biomass growth in the soil without additives. The BC1 composite can be used in pollutant sorption processes. However, BC5 has great potential as a soil additive in crop yield and plant growth.
