“…Recently, a semi-continuous cultivation strategy, considered suitable for pilot or up-scale cultivation, has been implemented for simultaneous wastewater treatment and valuable product generation by microalgae [76][77][78]. In this strategy, a portion of the previously grown microalgal cultures is retained in bioreactors as seed cultures for the next round of wastewater treatment, which also brings fresh nutrients.…”

“…Consequently, the sustainable reclamation of resources from wastewater holds the potential to generate revenue by creating marketable products, ensuring the safety of water reuse, and upholding water quality standards tailored to specific applications and economic objectives [141]. To effectively integrate circular economy (CE) principles into the wastewater sector, besides technological advancements, various other factors such as financial viability, societal impact, environmental considerations, risk assessment, and energy efficiency must be carefully weighed.…”

In 2019, a staggering 931 million tons of food went to waste, which is equal to about 17% of all the food available in stores. Dealing with this waste and managing wastewater from various industries will be among the world’s top challenges soon. This is because the global population is expected to grow to around 9 billion people by 2050. Food processing effluent is characterized by valuable material in considerable concentrations, including proteins and lipids with low concentrations of heavy metals and toxicants. Developing an integrated management system for food-processing wastewater should focus on recovering abundant resources, improving the economic value of the process, and mitigating the organic contaminant in the food-processing effluent. This state-of-the-art will review the wastewater management processes of the food processing industry. The latest wastewater treatment processes in different food processing sectors will be reviewed. This review will encompass various physicochemical treatment and recovery techniques, such as precipitation, membrane technology, solvent extraction, foam fractionation, adsorption, and aqueous two-phase systems. Additionally, it will delve into bio-treatment processes that leverage microorganisms and/or enzymes to utilize nutrients found in food-processing wastewater as cost-effective substrates for the production of valuable products. This includes a detailed examination of microalga biomass production within wastewater treatment systems. Finally, the review will put forward future research directions aimed at integrating the principles of the circular economy and developing comprehensive food-processing wastewater management systems.

“…Wastewater generation and atmospheric pollution have become two of the biggest environmental concerns in the last decades, and urgent measures are needed to decrease the impact they have on our planet, with terrible consequences such as eutrophication of aquatic environments, acid rain, depletion of O 3 in the stratosphere, and global warming amongst others (Mudliar et al, 2010;Mathur and Balomajumder, 2013;Choudhary et al, 2016;Sánchez-Morales et al, 2018). In this context, Oliva et al ( 2019) studied a novel bacterial LED-illuminated tubular PBR and compared it with a conventional biotrickling filter for the continuous abatement of toluene, which was chosen as a model volatile organic compound.…”

In the last years, there were two fields that experienced an astonishing growth within the biocatalysis community: photobiocatalysis and applications of flow technology to catalytic processes. Therefore, it is not a surprise that the combination of these two research areas also gave place to several recent interesting articles. However, to the best of our knowledge, no review article covering these advances was published so far. Within this review, we present recent and very recent developments in the field of photobiocatalysis in continuous flow, we discuss several different practical applications and features of state-of-the art photobioreactors and lastly, we present some future perspectives in the field.
