“…A microalgae biorefinery could have different alternatives for technological selection: chemistry, biochemistry and thermochemistry. The set of several process units for microalgae biomass should involve sustainability concepts, wide range of products and profitability (Dimian & Bildea, 2008;Gorry et al, 2018).…”

Microalgae have various advantages over vegetable crops, such as their growth speed, the greater consumption of CO2 and production of O2, and the vast variety of products where they can be used. For this reason, the present work seeks to quantify the trends that exist in microalgae research, by running related keywords in Scopus databases in a span of ten years. The central words used were related to biorefineries, microalgae, products and simulation. Likewise, the Wizdom.ai platform and VosViewer data analysis software were used. It was found that between 2015 and 2019, publications increased around 74 and 89 %. The graphical and statistical analysis through VosViewer allowed identifying the relationship between biorefinery and microalgae. Which showed that there is a trend in publications on the topic of biofuels, and that there is still little information corresponding to the biorefinery concept related to the analysis between microalgae and process simulation. Based on a global analysis of the abstracts of most of the publications, the main difficulties and information gaps in the processes under the biorefinery concept were identified, especially relating processes, costs, circular economy and environmental aspects.

“…Otherwise, due to its versatile composition, microalgal biomass is presented to be one of the most promising biore nery feedstock providing alternatives for different areas, such as food, feed, cosmetics and health industries, fertilizers, plastics, and biofuels. Furthermore, microalgae can also be integrated in process of wastewater treatment and CO 2 sequestration (Gorry et al 2018). However, carbon, nutrient, and water requirements for microalgae cultivation are still a major bottlenecks for an e cient and costeffective large-scale microalgae biomass production (Kannah et al 2018).…”

This paper aims to study a new growth media using cheese whey and drainage water from agriculture for indigenous microalgae cultivation for value-added product generation. In this context, four combinations are studied beside the BG11 as reference, where BG11/Cheese whey (60/40, %v/v), drainage water 100%, drainage water/Cheese whey (60/40, % v/v), and Cheese whey 100 % have been used. Moreover, investigated parameters are biomass dry weight, pH variation, total chlorophyll and carotenoid content. Results showed that used growth media have a significant impact on microaglae culture, particularly in terms of cells growth, pigment content and pH variation. Moreover, the mixture BG11/Cheese whey (60/40, %v/v) shows the best impact for total chlorophylls and carotenoids content. Likewise, the mixture cheese whey/drainage water (60/40, %v/v) presents a positive effect on pigments content. The use of cheese whey and drainage water lead to enhance the biomass and pigment production. This study showed that using agro-industrial C-rich wastes and drainage water enhanced microalgae biomass and pigment content, thus contributing to pollution abatement. This will contribute to both reducing the cost of production and resources recycling.
