Abstract
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.
