Description du projet
Exploiter les eaux usées pour en dériver des bioproduits durables
Les eaux usées ne sont pas nécessairement un fardeau, elles peuvent même constituer une ressource précieuse. Le projet SABANA, financé par l’UE, va révolutionner l’industrie des bioproduits en développant une bioraffinerie à grande échelle intégrée basée sur les microalgues qui exploite l’eau de mer et les nutriments provenant des eaux usées pour produire des biostimulants, des biopesticides, des additifs pour l’alimentation animale, des biofertilisants et des aliments pour animaux aquatiques. En récupérant les nutriments des eaux usées, du centrat et du fumier de porc, SABANA minimise les déchets et la consommation d’énergie. Il répond au besoin pressant de solutions durables pour l’agriculture et l’aquaculture, en fournissant des bioproduits qui améliorent le rendement des cultures et la production piscicole.
Objectif
SABANA aims at developing a large-scale integrated microalgae-based biorefinery for the production of biostimulants, biopesticides and feed additives, in addition to biofertilizers and aquafeed, using only marine water and nutrients from wastewaters (sewage, centrate and pig manure). The objective is to achieve a zero-waste process at a demonstration scales up to 5 ha sustainable both environmentally and economically. A Demonstration Centre of this biorefinery will be operated to demonstrate the technology, assess the operating characteristics of the system, evaluate environment impacts and collaborate with potential customers for use.
The key advantages of SABANA project are: the sustainability of the process, using marine water and recovering nutrients from wastewaters while minimizing the energy consumption, and the socioeconomic benefits, due to the relevance of the target bioproducts for two major pillars in food production as agriculture and aquaculture. Bioproducts capable of increasing the yield of crops and fish production are highly demanded, whereas recovery of nutrients is a priority issue in the EU. Instead of considering wastewater as an inevitably useless and problematic residue of our society, SABANA acknowledges its potential as an opportunity for economically relevant sectors.
SABANA project includes (i) the utilization of microalgae-bacteria consortia and in co-culture with other algae to control grazing species, (ii) the implementation of efficient thin-layer cascade and raceway, (iii) the scale-up of reactors to ensure stable operation, (iv) to use marine water to increase the sustainability of the process; (v) to recover nutrients from wastewaters, (vi) to develop harvesting processes taking into account the remaining water, (vii) to establish processes for mild/energy efficient extraction of bioproducts, (viii) to process residual biomass to produce biofertilizers and aquafeed in zero-waste schemes, (ix) using robust and sustainable technology
