There is a great demand for environmentally friendly carbon materials as an alternative to fossil raw in industrial production. Microalgae biomass can be valuable renewable source the production of biochar. The study examined effect pyrolysis temperature on chemical composition, morphological features and degree order structure biochar based green microalgae – Chlorella sp. Thermochemical conversion was carried out at 400÷900 oC CO2 atmosphere. obtained material had porous structure. It found that increased, yield decreased from 38.4 21.9 wt%, while its aromaticity stability, determined by H/C molar ratio, increased. Based results FTIR Raman spectroscopy, it evidenced produced 400÷500 distinguished presence functional groups double bonds (i.e. –NH2, C–O, C=C, C=N, N=O) well high (ID/IG=0.2). As increases, amorphous nature began develop. This could provide data proper selection algae obtain with desired graphite-like properties.

Synergistic valorisation of wastewater microalgae: Sulphuric acid-assisted phosphorus recovery and enhanced electrochemical performance of biochar for supercapacitors

Chemical Engineering Journal, Год журнала: 2024, Номер 494, С. 152986 - 152986

Опубликована: Июнь 11, 2024

This study proposes a strategy for phosphorus recovery from algae biomass while simultaneously enhancing the electrochemical capacitance of resulting biochar in supercapacitor applications. Use sulphuric acid leaching process on both wastewater microalgae and seaweed demonstrated high rates, ranging 93.4% to 95.4%, at same time retaining 52.7% 58.6% Fe content biochars. By modifying sequential order (L) physical activation (A) as LA AL, allows optimisation properties activated During process, more porous structure formed S-containing functional groups occurred compared AL which explained higher specific (486.3F g−1 current density 1 A g−1) biocarbon with process. Consequently, life cycle assessment this revealed significant global warming reduction potential 1.34–2.94 tonnes CO2-eq/yr each tonne produced. indicates that acid-assisted production could be sustainable waste management carbon sequestration, generating economic profits valorised material energy storage

Phycoremediation of potentially toxic elements for agricultural and industrial wastewater treatment: Recent advances, challenges, and future prospects

Desalination and Water Treatment, Год журнала: 2024, Номер unknown, С. 100505 - 100505

Опубликована: Июнь 1, 2024

Phycoremediation is an eco-friendly and low operational-cost technique. It promotes green technology for biofuel production, high nutrient recovery, wastewater treatment through microalgae. This review encompasses a set of algal-based remediation methods potentially toxic elements (PTEs) from agricultural discharges industrial wastewater. Large-scale algae production approaches, such as suspended cultures in open ponds or closed reactors immobilized cultures, include biofilm matrix-immobilized systems biomass the removal nutrients, well PTEs. Fundamentals PTEs using microalgae are biosorption bioaccumulation, thus, this summarizes how beneficial treatment. Further, describes recent technologies, i.e., bioreactors, high-rate algal ponds, commercial sorption, etc., used their specifications contaminants effluent. Wastewater process utilizes macro-algae both conventional facultative advanced with photo-bioreactors. also covers advancement bioremediation nutrients PTE Lastly, concluded various limitations, challenges, prospects on implications wastewater, considering carbon neutrality circular economy.

Current and future perspectives of a microalgae based circular bioeconomy to manage industrial wastewater– A Systematic Review

Physiologia Plantarum, Год журнала: 2024, Номер 176(1)

Опубликована: Янв. 1, 2024

Abstract Post technological advancements and industrialisation, the recovery of resources by treating wastewater is gaining momentum. As global population continues to grow, need for water becoming increasingly urgent. Therefore, re‐utilisation an important factor in preservation life on this planet. Wastewater classified according its source origin. When left untreated, effluent causes several environmental hazards poses health issues as they have higher concentrations nutrients toxic heavy metals. Currently, conventional methods exist treat handle wastewater, but generate secondary waste post‐treatment are not sustainable. Microalgae‐based treatment highly sustainable, cost‐efficient aligns with concept circular bioeconomy. The biological effluents using microalgae has advantages. Approximately 1.83 kg CO 2 sequestered per dry biomass during cultivation. Among all sustainable alternatives, offer better productivity utilising a concentration wastewater. wastewater‐grown efficiency producing commercially metabolites. This systematic review highlights competence different sources their industrial perspectives. also gives overview biproducts produced from microalgae‐based treatment.

Reduction of biogenic CO ₂ emissions, COD and nutrients in municipal wastewater via mixotrophic co-cultivation of Chlorella vulgaris – aerobic-activated sludge consortium

Environmental Technology, Год журнала: 2025, Номер unknown, С. 1 - 15

Опубликована: Фев. 16, 2025

In this study, biogenic CO2 emissions, COD and other nutrients (i.e. TP, TN NH4+-N) from aerobic treatment in municipal Wastewater Treatment Plants (WWTP) were quantified reduced by phycoremediation using a mixotrophic co-cultivation of Chlorella vulgaris activated sludge. It has been shown that the microalgae sludge consortium (A-ASR, R1) outperformed normal-activated system (ASR, R2). fact, estimated emissions with algae mark 1.20-fold higher removal, marks 1.40-fold TP 1.70-fold NH4+-N compared to normal Meanwhile, due aeration, NO3–-N concentration increased both reactors because some Ns oxidized through nitrification. Furthermore, again during C. stationary growth; thus, addition every 4 days (optimal time) was implemented maintain algae-bacteria balance. The results suggest integrating GHG water pollutants single, concurrent process can significantly enhance sustainability efficiency wastewater plants, which not explored comprehensively. Finally, leveraging capabilities for carbon sequestration, study provide practical guidance achieving neutrality WWTP.
