Water crisis around the world leads to a growing interest in emerging contaminants (ECs) that can affect human health and environment. Research showed thousands of compounds from domestic consumers, such as endocrine disrupting chemicals (EDCs), personal care products (PCPs), pharmaceuticals active (PhAcs), could be found wastewater concentration mostly ng L−1 μg L−1. However, generally, treatment plants (WWTPs) are not designed remove these ECs their discharge levels. Scientists looking for economically feasible biotreatment options enabling complete removal before discharge. Microalgae cultivation is likely approach removing simultaneously any residual organic nutrients. Microalgal growth rate efficiency affected by various factors, including light intensity, CO2 addition, presence different nutrients, etc., parameters greatly help make microalgae more efficient. Furthermore, algal biomass harvests repurposed produce bulk sustainable aviation fuel, biofuel, bioplastic, biochar; this significantly enhance economic viability. Therefore, review summarizes microalgae-based bioprocess mechanisms wastewaters highlights strategies improve efficiency. shows role profile relevance using ECs-treated green products, well challenges future research recommendations.

Rapid urbanization has substantially increased freshwater consumption and consequent wastewater generation. The produced is an abundant resource of phosphorus, nitrogen, organics. Currently, well-established activated sludge processes are utilized in conventional treatment plants to remove However, removing nitrogenous phosphorus compounds continues be challenging energy-intensive for urban plants. Therefore, the current study aims understand how photosynthetic microalgae can recover nitrogen from wastewater-grown biomass may used as a biofertilizer biostimulant. Utilizing treated with promotes plant growth manner similar other organic manures fertilizers while minimizing nutrient loss soil. Furthermore, microalgal recovery nutrients could have potential energy reductions 47% 240% respectively. In addition producing suitable variety irrigation systems, sustainable alternative that reduce inorganic fertilizer usage.

In approximately one decade, global temperatures will likely exceed a warming level that United Nations Intergovernmental Panel on Climate Change report considers "red alert for humanity". We propose exploring tidal flat diatoms to address climate change challenges. Tidal flats are extensive coastal ecosystems crucial the provisioning and regulation of aquatic environments. Diatoms contribute biomass production account 20% primary productivity 40% annual marine production, making them nutrient cycling sediment stabilization. Potential CO2 removal from Korean by is estimated be 598,457–683,171 t equivalents (CO2e) annually, with economic value blue carbon (BC) resulting diatom activity being US$ 17.95–20.50 million.
