InteGRated systems for Effective ENvironmEntal Remediation

Description du projet

Les bactéries «électriques» éliminent les déchets et génèrent de l’électricité

Les processus industriels modernes sont à l’origine d’une pollution massive du sol et de l’eau dans le monde susceptible de porter un grave préjudice aux écosystèmes et à la santé humaine. Les efforts visant à décontaminer ou assainir ces sites sont onéreux, complexes et énergivores. La bioremédiation, qui utilise des microbes comme les bactéries et les champignons pour décomposer les polluants toxiques en substances inoffensives, est moins chère et plus durable que les autres alternatives de dépollution. L’initiative GREENER développe une solution hybride à faible coût qui intègre la bioremédiation et la technologie des piles à combustible microbiennes. Ces microbes électriquement actifs non seulement nettoieront, mais produiront également de l’électricité.

Objectif

Increasing chemical pollution seriously compromises the health of ecosystems and humans worldwide. Hazardous compounds, such as polycyclic aromatic hydrocarbons, heavy metals and emerging pollutants contaminate soils/sediments, ground and surface waters. To prevent/minimise the risks associated with the accumulations of these chemicals in the environment it is key to establish low-cost/green methodologies for the treatment and redevelopment of contaminated areas. Several physico-chemical methods have been explored to remove pollutants in the environment, but these are complex, energy consuming or expensive. The exploitation of the capability of bacteria, fungi and phototrophs to transform toxic contaminants into harmless end-products, can lead instead to cheap and sustainable bioremediation alternatives.
GREENER proposes the development of innovative, efficient and low-cost hybrid solutions that integrate bioremediation technologies with bio-electrochemical systems (BES). BES, such as microbial fuel cells, break down organic contaminants through the action of electroactive bacteria while generating electrical current. We will investigate the synergetic effect of different bioremediation strategies and demonstrate effective pollutants removal in water and soil/sediments, while generating side products of interest, such as bioelectricity. The type and entity of contamination, along with the specific physico-chemical/microbial characteristics of the environment to be depolluted, will feed into a decision-making toolbox. The latter will allow the establishment of ad hoc integrated solutions, which will take into account effectiveness of biodegradation, costs, environmental risks and social aspects. Fundamental research will be performed at lab-scale, while pilot-tests will be used to proof the scaling-up feasibility for field applications. Environmental benefits and risks, compared to standard remediation approaches, including energy efficiency, will be investigated.
