“…Escalating population and widening industrialization utilizes a large amount of freshwater for different purposes and generates a huge volume of wastewater. The release of untreated wastewater into the environment creates a severe danger to the ecosystem (Ummalyma et al 2021 ). Qadir et al ( 2020 ) showed that presently approx.…”

“…To overcome these existing challenges, there is an increasing attraction towards biological green processes for wastewater treatments and pollutants remediation all over the world. To deal with the emerging concerns about environment and biodiversity preservation, there are stringent regulations on safe discharge, which has directed the need for alternative innovative and sustainable processes for waste mitigation (Hussain et al 2021 ; Ummalyma et al 2021 , Singh et al 2020 ; Zhuang et al 2020 ; Saravanan et al 2018; Sharma et al 2021 ). In this regard, the biological wastewater treatment option based on the microalgae-based process offers potential promises (Sirohi et al 2021a , 2021b ; Yu et al 2021 ; Joun et al 2021 ).…”

“…Microalgae are attractive biocatalysts to meet the wastewater treatment process and energy crisis. Microalgae can grow faster, remove nutrients, and treat wastewater simultaneously produce biomass suitable for biofuels and biorefinery products (Ummalyma et al 2021 ; Hussain et al 2021 ). Microalgae can able to grow different trophic modes of nutrition.…”

“…Photoautotrophic algae trap CO 2 and sunlight from the atmosphere for energy and carbon for their growth and reproduction meantime helping in the mitigation of CO 2 and valuable products. Heterotrophic microalgae take organic nutrients for carbon and energy sources from the wastewater and produce biomass for biorefineries whereas mixotrophic microalgae can grow by trapping CO 2 and organic carbon available from the wastewater as energy and carbon source for their multiplication and produce biomass for different applications (Hussain et al 2021 ; Ummalyma et al 2021 ). Several kinds of research have been performed for the purification of wastewater using different microalgal species.…”

“…Several kinds of research have been performed for the purification of wastewater using different microalgal species. A recent report highlighted that microalgae have the potential for effective removal of high concentrations of organic carbon, phosphorous, and nitrogen from food processing wastewater and produced different value-added products (polysaccharides, biofuels, pigments, and amino acids (Nur and Buma 2019 ; Ummalyma et al 2021 ). In this present review, discussing the importance of food processing wastewater as a nutrient medium for low-cost biomass for circular bioeconomy biorefinery products, and characterization of various food processing wastewaters are highlighted.…”

Microalgae are recognized as cell factories enriched with biochemicals suitable as feedstock for bio-energy, food, feed, pharmaceuticals, and nutraceuticals applications. The industrial application of microalgae is challenging due to hurdles associated with mass cultivation and biomass recovery. The scale-up production of microalgal biomass in freshwater is not a sustainable solution due to the projected increase of freshwater demands in the coming years. Microalgae cultivation in wastewater is encouraged in recent years for sustainable bioeconomy from biorefinery processes. Wastewater from the food industry is a less-toxic growth medium for microalgal biomass production. Traditional wastewater treatment and management processes are expensive; hence it is highly relevant to use low-cost wastewater treatment processes with revenue generation through different products. Microalgae are accepted as potential biocatalysts for the bioremediation of wastewater. Microalgae based purification of wastewater technology could be a universal alternative solution for the recovery of resources from wastewater for low-cost biomass feedstock for industry. This review highlights the importance of microalgal biomass production in food processing wastewater, their characteristics, and different microalgal cultivation methods, followed by nutrient absorption mechanisms. Towards the end of the review, different microalgae biomass harvesting processes with biorefinery products, and void gaps that tend to hinder the biomass production with future perspectives will be intended. Thus, the review could claim to be valuable for sustainable microalgae biomass production for eco-friendly bioproduct conversions. Graphical abstract
