“…However, the activated sludge treatment process stands out for its low operating cost. In fact, this method consists of physically, mechanically, chemically, and biologically stimulating the aerobic biota of raw effluents [4]. Although there are necessary technologies to reduce the disposal of most of the waste generated, the high costs, poor sustainability, and lack of greater integration in the management of this waste have been pointed out by specialists as the reasons why it is still a global challenge.…”

“…Biofertilizers fit into this context as a viable, healthy, and pollution-free option, currently being considered the best substitute for chemical fertilizers. Among the various types of biofertilizers, formulations based on microorganisms, including cyanobacteria and microalgae, have been growing substantially due to their excellent ability to increase soil fertility, improve nutrient quality and increase the productivity of different crops [4]. In parallel, the use of microalgae in the biostimulants market makes it possible to reduce the number of fertilizers needed for crops and thus indirectly increase agricultural sustainability.…”

Microalgae are organisms with great potential for the use of goods and services in areas of social and commercial interest. The application of bioproducts of microalgal origin for the purpose of feed in aquaculture and agriculture directly influences the generation or mitigation of environmental impacts. Its use in the treatment of wastewater allows the reduction of nutrients such as nitrogen, phosphorus, and CO2, providing a system that acts in the reuse and use of water resources, generating the return of cleaner water to bodies of water and acting in the reduction of the gases greenhouse effect. Microalgae biomass is presented as an alternative to generating a wide variety of value-added products that, in recent years, given its biotechnological potential, have been gaining ground in agribusiness. This document aims to show the application and current perspectives for obtaining biomass of microalgae from crops in wastewater that can be used as raw material for the production of biofertilizers, biostimulants, feed additives that encourage reuse, transformation, recovery, and savings of resources to promote bioeconomic and circular economy processes. Generate strategies to develop practices in the agricultural sector with high productivity, quality, and efficiency, which in turn can be sustainable, friendly, and provide economic advantages, part of the need to use bioresources and implement circular bioeconomy concepts.
