The RENUWAL network (320RT0005 - RED IBEROAMERICANA PARA EL TRATAMIENTO DE EFLUENTES CON MICROALGAS) is a thematic network focused on effluents treatment with microalgae. Microalgae can be used to recover the nutrients contained in various effluents, thus improving the sustainability of many processes. To achieve efficient processes, it is necessary to evaluate each application in detail based on the effluents to be processed. Depending on the process, the algal biomass obtained may be of interest for its application in different sectors and final products with extra added value, i.e., pharmaceutical, cosmetic, agri-food-livestock-aquaculture, environmental, chemical, or even energy.
This network was granted in the 2019 CYTED call (Ibero-American Program for Science and Technology for Development; https://www. cyted.org/es/cyted) to start in 2020 and until the end of 2024. The RENUWAL network is formed by several research groups belonging to ten different Ibero-American countries and seven companies working with microalgae (https://www.cyted.org/es/renuwal). We have gathered all the abstracts from the III RENUWAL Meeting celebrated on the 2nd and 3rd of June 2022 into this digital book. In this meeting, several videos were held presenting an article representative of the group. A round table was held where the groups shared their research, opening a framework to cooperate.
