“…nutrient recovery and biomass. The author of [41] investigated the impact of different dilutions of fresh leachate (5%, 10%, 15%, 20% and 25%) using treated municipal wastewater on the growth and nutrient recovery potential of Scenedesmus sp. They found the highest removal efficiencies of 100%, 94% and 96% in 15% of fresh leachate for nitrite, ammonium, and phosphorus removals, respectively.…”

“…Figure 10 depicts a number of challenges (economic and biological) associated with the microalgae-based wastewater treatment process as well as ideas in order to deal with these issues. Microalgae cell growth can be limited by low nutrient in wastewater, however this is one of the biological obstacles that can be solved by combining different wastewaters, adding inorganic compounds, fertilizers, and food waste [41,74,91,105]. Using agricultural waste (poultry litter) mixed with municipal wastewater to cultivate Acutodesmus obliquus result in a biomass 74.67% higher than using agricultural waste as culture medium [41].…”

In addition to producing bioenergy and molecules with high added value, microalgae have been recognized as an efficient microorganism for wastewater treatment. However, a major obstacle preventing its widespread use is the high energy cost of pretreatment, cultivation and downstream processes. Different types of wastewaters have been tested as culture mediums for microalgal biorefinery system. This review gives a summary of the most used microalgae strains for wastewater treatment, as well as information on the physical and chemical characteristics of domestic, agricultural, and industrial wastewaters. It also discusses wastewater pretreatment techniques, nutrient uptake and removal, biomass production and biomolecules productivities. There is also discussion on how microalgae remove contaminants from wastewater. Additionally, the problems and restrictions of microalgae-based wastewater treatment are explored, and recommendations are made for additional study and advancement. This literature review demonstrates that microalgae monoculture systems have proven to be beneficial as an innovative wastewater treatment technology, due to its high efficiencies in pollutant removals and biomolecule production; however, the upstream and downstream treatment pose a limit to industrialize the process. Until now, there has been no conventional design of the wastewater treatment process using microalgae in the biorefinery system, which constitutes a huge gap to assess a real life cycle assessment (LCA) and techno economic analysis (TEA).

Valorization of biorefinery residues for sustainable fertilizer production: a comprehensive review

The management of biowaste and agricultural solid waste is gaining attention due to rising landfill disposal costs and the need for locally available agricultural feedstocks. The biorefinery concept aims to achieve zero waste through valorizing residues as fertilizers. Despite containing NPK macronutrients, residues may not promote plant growth due to limited nutrient availability and phytotoxic compounds. The production of valuable organic, mineral-organic, or mineral fertilizers with confirmed agronomic properties as marketable biorefinery products remains understudied. This comprehensive review broadens our understanding of fertilizer production in biorefineries, which complements the energy (thermal, biogas, biodiesel) and chemical compounds (e.g., succinic acid, propanediol, protein concentrates) that are also generated within biorefineries. It is among the first reviews to investigate the importance of valorizing biorefinery residues as fertilizers, emphasizing methods leading to commercial products and the rationale behind this process. The findings confirm that directly applying unprocessed residues to the soil does not fully exploit their value as by-products. This study contributes to the practical analysis of barriers (legal, chemical, biological, technological) and opportunities (rising prices and reduced global availability of mineral fertilizers) related to fertilizer production in the biorefining process.
