The application of beneficial microorganisms improves the quality of the water, prevents the proliferation of certain diseases and reduces the environmental impact

It is currently in the testing phase and the objective is that the treated water can be incorporated into a circular economy model through its subsequent agricultural use.

This biosolution could be applied to the treatment of wastewater in sewage plants, in addition to favoring the reduction of the carbon footprint in the industry

Sherpa do Mar's Blue Bioprana project seeks to transfer biotechnology solutions for the treatment and management of organic matter from agribusiness to aquaculture, which would generate numerous benefits for the latter sector. "It is a cocktail of microorganisms that transforms putrefaction processes into fermentation processes, which improves water quality, in addition to reducing environmental impact and the proliferation of diseases," says Carla Salazar, co-founder of the mother company of this initiative, Bioprana, based in Pontevedra.

This would not only translate into better welfare for fish in the aquaculture industry, it would also reduce the use of antibiotics in fish farm production processes. "These waters treated with beneficial microorganisms could be reused even in the agricultural sector, which would favor a circular economy model, increasing the profitability of farms," ​​he says.

Blue Bioprana is currently accelerating in the Euroregional Sherpa Journeys program to support entrepreneurship in the marine-maritime sector and its technology is already in the testing phase. "Thanks to the Sherpa do Mar program we have been able to establish contacts with the Portuguese company with which we are conducting the testing, Riasearch, specialized in experimental trials in the aquaculture environment," says Salazar.

In three months, both Salazar and the biotechnologist Jesús González, the other promoter of the project, foresee that the product will be ready for its subsequent launch on the market. They assure that its application will be increasingly necessary in the coming years due to the increase in restrictions in Europe regarding the use of pesticides and chemical inputs in different industries.

Blue economy

Last year the mother company of Blue Bioprana launched an R&D&i laboratory in the Porto do Molle Business Park, in Nigrán. This was the germ of the transfer of Bioprana biosolutions from the agro-industrial sector to the blue economy. “Sherpa do Mar made it easy for us to get to where we are now,” says Salazar. And not only that, thanks to this program, your project has been selected to participate in the European FANBEST project to promote the transfer of technology from the blue economy to SMEs.

The next step, they comment, will be to go further and apply this system to the treatment of wastewater in treatment plants and measure the carbon footprint generated by the aquaculture and agro-industrial sectors to reduce their impact, promoting the circular economy.

About Sherpa do Mar


Sherpa do Mar is a project integrated in the INTERREG VA Spain-Portugal Cross-Border Cooperation Program (POCTEP) 2014-2020, co-financed 75% by ERDF funds, whose purpose is to launch a cross-border network of entrepreneurship in the marine-maritime field and blue economy, through the Sherpa Journeys program, which favors job creation and increased business competitiveness through the promotion of technology-based companies.

The project is led by the University of Vigo, through the REDE research group, Campus do Mar and the R&D Office, and has the participation of the Vigo Free Zone Consortium, the Galician Innovation Agency (GAIN) and the universities of Santiago and A Coruña. On the part of Portugal it has the participation of the Asprela Technology Transfer Association (UPTEC), UPorto-Innovação of the University of Porto (UPIN), the Interdisciplinary Center for Marine and Environmental Research (CIIMAR) and the Fórum Oceano-Associação da Economia do Mar.
