Titre
InCIRCULAR - Integrated production of biochar from residual biomass to boost local agriculture
Résumé
While industry has overcome agriculture heritage, farming and forestry continue to be important economic clusters in Estarreja. However, the exodus from farms to factories has led to increasing land abandonment and proliferation of invasive plant species that require a more effective management towards wildfire prevention and land protection. In turn, valorisation of this residual biomass can be achieved through its pyrolysis for production of biochar that has emerged as a way to improve soil quality. Biochar sequesters carbon and retains most of the inorganics of raw biomass into plant-available forms that can provide fertilisation upon soil application. Moreover, biochar produced from biomass loaded with contaminants (soil-borne metals) does not present major environmental risks, as they are retained onto the carbon matrix. Additionally, by raising soil pH, biochar turns most metallic contaminants non-bioavailable, thus helping to mitigate soil contamination. This research pursues an integrated approach to valorise residual forestry biomass existing in Estarreja (e.g. acacia and gorse) into biochar to further apply in local agricultural soils to increase their fertility and crop yield and decrease the inorganic fertilisers demand, with evident economic gains. Such approach will provide synergies between wildfires prevention, nutrient recycling, soil amelioration and boosting of agriculture under a local-based circular economy pathway that will benefit several stakeholders. The work programme encompasses biochar production from local residual biomass, retrofitting of the pyrolysis process to target suitable biochar properties and determination of the agronomic value and environmental safety of the produced biochar upon soil application.

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 7, 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.
