“…The composition and contamination loads of the FPWWs depend on the type of industry, raw materials, and processing technologies (Amin et al 2021 ; Subha et al 2020 ; Li et al 2019 ). It is non –toxic due to traces of chemicals such as antibiotics and heavy metals; however, microalgae biomass production in FPWWs is suitable for high-value chemicals such as proteins, polymers, pigments, polysaccharides, and DHA (Gecim et al 2021 ; Humaidah et al 2020 ). The difference in nutrient composition of FPWWs also influences microalgae growth and biochemicals.…”

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

“…Thus, the malt extractivity is a function of several variables, such as the total content of reducing sugars, the total time of saccharification, the drying temperature, the moisture content of the malt. In general, the combination of materials and methods chosen in this study can be successfully used in the future to conduct further research and to form a reliable scientific base for studying the possibilities of intensifying the processes of high-quality brewing, taking into account the features of modern technological development in this line (Gecim et al, 2020;Muster-Slawitsch et al, 2014).…”

Brewing is a complex process that involves many stages and successive operations. The issues of intensifying the brewing processes are of great importance in improving the ways to obtain a high-quality finished beer product and maintain high standards of its quality in the future. The relevance of the subject matter is conditioned by the stable demand for high-quality beer products in society and the urgent need to create effective technologies for the production of high-quality beer, taking into account the introduction of the latest technologies for the intensification of brewing processes. The purpose of the study is to determine the main factors that are important from the standpoint of intensifying the processes of quality brewing, in the context of assessing the prospects for their subsequent consideration when planning the beer production processes. The leading approach of this study is a combination of a systematic analysis of the peculiarities of brewing processes in the context of searching for opportunities for its intensification, with an analytical study of real options for intensifying the brewing processes, from the standpoint of maintaining high-quality standards of finished beer and increasing the overall production rate. The main results obtained in the course of this study should be considered the substantiation of the main factors of the brewing processes intensification in the context of creating a mathematical model for calculating the possibilities of its implementation in the activities of breweries to increase the rate of brewing high-quality beer. The prospects for further research are determined by the preservation of a stable demand for high-quality beer products, combined with an increase in the need to intensify the processes of its production, in accordance with the set standards for the quality of beer production.

“…Various separation techniques have been proposed to extract the PHA granules from the cells [94][95][96][97]. For extensive reviews on the production and recovery of PHA from MMC, the following papers are suggested reading: [31,[98][99][100][101][102][103]. Here, we only focus on the production of crotonic acid from PHA as a downstream process to valorize the bio-based PHBV that is produced from wastewater and does not meet polymer market quality.…”

Recovery Techniques Enabling Circular Chemistry from Wastewater

In an era where it becomes less and less accepted to just send waste to landfills and release wastewater into the environment without treatment, numerous initiatives are pursued to facilitate chemical production from waste. This includes microbial conversions of waste in digesters, and with this type of approach, a variety of chemicals can be produced. Typical for digestion systems is that the products are present only in (very) dilute amounts. For such productions to be technically and economically interesting to pursue, it is of key importance that effective product recovery strategies are being developed. In this review, we focus on the recovery of biologically produced carboxylic acids, including volatile fatty acids (VFAs), medium-chain carboxylic acids (MCCAs), long-chain dicarboxylic acids (LCDAs) being directly produced by microorganisms, and indirectly produced unsaturated short-chain acids (USCA), as well as polymers. Key recovery techniques for carboxylic acids in solution include liquid-liquid extraction, adsorption, and membrane separations. The route toward USCA is discussed, including their production by thermal treatment of intracellular polyhydroxyalkanoates (PHA) polymers and the downstream separations. Polymers included in this review are extracellular polymeric substances (EPS). Strategies for fractionation of the different fractions of EPS are discussed, aiming at the valorization of both polysaccharides and proteins. It is concluded that several separation strategies have the potential to further develop the wastewater valorization chains.
