The global objective of the ALGAENAUTS innovation project is to achieve and validate the pre-commercial industrial production of biopesticide and biostimulant products for agriculture by using seawater and wastewater as nutrients source, from microalgae strains with proven biopesticide and biostimulant activity.

Optimisation of large-scale microalgae production and processing into biopesticides and biofertilisers

First Step

Five selected strains with proven antifungal, antibacterial and biostimulant activity will be cultivated using wastewater. Culture conditions and operational aspects of microalgae production will be optimized, and the yield and efficiency of large-scale production systems. The optimisation of harvesting and downstream process is mandatory in order to ensure the most efficient operation cost. Marine water and wastes (sewage and pig manure) will be used to achieve sustainable processes. Microalgae systems optimised will be capable of operate in continuous mode for six months without collapses, at productivities higher than 70 t/ha•year, with power consumptions lower than 5 /m3, and recovering more than 90% of nutrients contained into wastes. Up to 10 t /ha•year and 2 tP/ha•year will be recovered at biomass production cost below 1.0 €/kg.

Scale-up of integral utilization of biomass processes

Second Step

The harvesting process will allow recovering more than 95% of produced biomass, with power consumptions below 0.1 kWh/m3. Mild processing technologies will be used to extract up to 80% of high-value products from the microalgae biomass, without damaging the residual biomass for its latter utilization to produce biofertilizers. Only wet processes will be used to enhance the sustainability of the process, the utilization of non-safe solvents being disregarded.

Market validation and registration assessment

Third Step

Final products formulated (biopesticides and biofertilisers) will be validated through field trials at real crop conditions. Field trials will be developed in an Experimental Center with fully monitored conditions in horticultural and fruits crops. Additionally, target products will be evaluated and validated with end-users such as distributors and farmers. Also, market, social and sustainability aspects such as social and market acceptance, environmental impact and the carbon and water footprint mitigation will be evaluated. The legal framework of biopesticides and biofertilisers produced will be studied for the registration assessment, according with the EU legislation, additionally to the legal framework of other key third countries for the interest of Biorizon´s external market.
