While soils of Estarreja continue to be important sinks of persistent contaminants, existing remediation techniques are often ineffective and fail when addressing multiple contaminants. Biochar – biomass pyrolysed for enhancing carbon sequestration and other biomass productivity – presents a dual potential for improving soil decontamination: its exceptionally high porosity can both promote adsorption of contaminants and provide habitat conditions for microbial biofilm development. It is hypothesized that the microbiomes existing in contaminated soils present enhanced abilities to thrive under such adverse environments, thus allowing for a natural improvement of the ecosystem services provided by the soil. The proposed research aims at a novel technique for remediating soil contamination, through development of biochar-attached biofilms made of mixed microbial cultures taken from those “dirty” soils identified in Estarreja and stimulated to oxidize both organic and inorganic contaminants. The work programme encompasses: microbial fingerprinting of the contaminated soils, ex situ development of biofilms cultivated from those microbiomes onto biochar carriers and assessment of the contaminant uptake kinetics.
Flávio Silva, FS (http://orcid.org/0000-0001-7025-0601) got his PhD in Environmental Sciences and Engineering in 2013 at the University of Aveiro. He is an environmental scientist and engineer with seven years of research in bioprocess technology and biorefinery concepts (energetic and material valorisation of waste streams). After PhD, he broadened his research into further environmental subjects to develop skills under a wider vision of ecosystem interactions, including earth surface processes, carbon and nutrient dynamics, integrated ecosystem services and soil remediation. Currently FS is a researcher at CESAM – Centre for Environmental and Marine Studies at the University of Aveiro, working on carbon/nutrient dynamics, soil biotechnology and resource recycling at both scientific and industrial interface levels. He worked as executive manager and field team coordinator in 1 national project and 2 European projects. He has co-supervised 17 MSc students and participated as jury examiner of 7 MSc theses. He is/was team member of 7 research projects (either European or national) and collaborator of 13 research projects (either European or national). He owns a granted patent, has authored 19 peer-reviewed papers (h-index 12, SCOPUS) and more than 30 oral or panel presentations in conferences. FS career has not been only focused on fundamental science but he also has advanced skills on R&D projects management, students mentoring, design of funding applications, as well as a strong expertise in collaboration between scientists and stakeholders, notably aiming at technology transfer.
