“…Finnfjord AS annually emit 300,000 tons of CO 2 and 1100 tons of NOx. The aim of our project was therefore to investigate possibilities to perform sustainable circular economy and utilize factory cooling water, CO 2 from fume and NOx to produce marine (diatom) biomass [10]. Analysis of chemical content, pollution and suitability of the biomass as feed/food were also planned.…”

“…Numerous recent publications have dealt with the large potential of microalgae to become future producers of energy, food and bioactive compounds [1][2][3][4][5][6][7][8][9][10][11][12]. The underlying reasons for this are that they are nutritious in terms of lipid and protein and the fact that they "grow" by binary fission (division), making them capable of doubling their biomass every day.…”

Mass Cultivation of Microalgae: I. Experiences with Vertical Column Airlift Photobioreactors, Diatoms and CO2 Sequestration

From 2015 to 2021, we optimized mass cultivation of diatoms in our own developed vertical column airlift photobioreactors using natural and artificial light (LEDs). The project took place at the ferrosilicon producer Finnfjord AS in North Norway as a joint venture with UiT—The Arctic University of Norway. Small (0.1–6–14 m3) reactors were used for initial experiments and to produce inoculum cultures while upscaling experiments took place in a 300 m3 reactor. We here argue that species cultivated in reactors should be large since biovolume specific self-shadowing of light can be lower for large vs. small cells. The highest production, 1.28 cm3 L−1 biovolume (0.09–0.31 g DW day−1), was obtained with continuous culture at ca. 19% light utilization efficiency and 34% CO2 uptake. We cultivated 4–6 months without microbial contamination or biofouling, and this we argue was due to a natural antifouling (anti-biofilm) agent in the algae. In terms of protein quality all essential amino acids were present, and the composition and digestibility of the fatty acids were as required for feed ingredients. Lipid content was ca. 20% of ash-free DW with high EPA levels, and omega-3 and amino acid content increased when factory fume was added. The content of heavy metals in algae cultivated with fume was well within the accepted safety limits. Organic pollutants (e.g., dioxins and PCBs) were below the limits required by the European Union food safety regulations, and bioprospecting revealed several promising findings.

“…Beyond wastewater and solid residues in the agro-industry, discussions can expand to the issue of gaseous effluents and the development of bioprocesses that play an important role in the treatment, since they are considered one of the primary sources of emissions and contamination in the industrial process [81,165]. One of the emission sources originates from burning biomass or fossil fuels, where coal is widely used as an energy source [166][167][168][169][170].…”

“…Another source of emissions of gaseous effluents is biodigesters, which can be used to produce methane to generate electricity and heat and can emit high concentrations of CO 2 and H 2 S [171]. In this scenario of the biological treatment of gaseous effluent, microalgae represent a promising strategy for the photosynthetic fixation of CO 2 and other compounds (e.g., H 2 S, sulfur oxides-SOx, and nitrogen oxides-NOx) present in the gas streams and offer the possibility of producing microalgae-based bioproducts and biofuels [165].…”

Agro-Industrial Wastewaters for Algal Biomass Production, Bio-Based Products, and Biofuels in a Circular Bioeconomy

et al. 2022

Recycling bioresources is the only way to sustainably meet a growing world population’s food and energy needs. One of the ways to do so is by using agro-industry wastewater to cultivate microalgae. While the industrial production of microalgae requires large volumes of water, existing agro-industry processes generate large volumes of wastewater with eutrophicating nutrients and organic carbon that must be removed before recycling the water back into the environment. Coupling these two processes can benefit the flourishing microalgal industry, which requires water, and the agro-industry, which could gain extra revenue by converting a waste stream into a bioproduct. Microalgal biomass can be used to produce energy, nutritional biomass, and specialty products. However, there are challenges to establishing stable and circular processes, from microalgae selection and adaptation to pretreating and reclaiming energy from residues. This review discusses the potential of agro-industry residues for microalgal production, with a particular interest in the composition and the use of important primary (raw) and secondary (digestate) effluents generated in large volumes: sugarcane vinasse, palm oil mill effluent, cassava processing waster, abattoir wastewater, dairy processing wastewater, and aquaculture wastewater. It also overviews recent examples of microalgae production in residues and aspects of process integration and possible products, avoiding xenobiotics and heavy metal recycling. As virtually all agro-industries have boilers emitting CO2 that microalgae can use, and many industries could benefit from anaerobic digestion to reclaim energy from the effluents before microalgal cultivation, the use of gaseous effluents is also discussed in the text.

“…Likewise, studies on the production of bioplastics using microalgae as an alternative to the use of petroleum-derived polymers have been reported [ 19 , 20 , 21 ]. Therefore, CO 2 capture systems with microalgae can be economic levers that enable the commercialization of these products while contributing to the mitigation of high concentrations of CO 2 on the planet [ 22 , 23 , 24 ].…”

Trends on CO2 Capture with Microalgae: A Bibliometric Analysis

et al. 2022

View full text Add to dashboard Cite

The alarming levels of carbon dioxide (CO2) are an environmental problem that affects the economic growth of the world. CO2 emissions represent penalties and restrictions due to the high carbon footprint. Therefore, sustainable strategies are required to reduce the negative impact that occurs. Among the potential systems for CO2 capture are microalgae. These are defined as photosynthetic microorganisms that use CO2 and sunlight to obtain oxygen (O2) and generate value-added products such as biofuels, among others. Despite the advantages that microalgae may present, there are still technical–economic challenges that limit industrial-scale commercialization and the use of biomass in the production of added-value compounds. Therefore, this study reviews the current state of research on CO2 capture with microalgae, for which bibliometric analysis was used to establish the trends of the subject in terms of scientometric parameters. Technological advances in the use of microalgal biomass were also identified. Additionally, it was possible to establish the different cooperation networks between countries, which showed interactions in the search to reduce CO2 concentrations through microalgae.
