  - L'OHMI - Estarreja a été créé pour étudier les multiples effets de l'activité industrielle dans la municipalité d'Estarreja, et pour contribuer à l'amélioration de la connaissance de ses effets et évaluer les progrès résultants des interventions d'atténuation déjà développées dans la région.

Flavio Silva	2022	SAYFERT - Safety and effectiveness of Estarreja-based fertilisers under circular economy principles	Pyrolysis Residual forest biomass Ecotoxicity Soil amendment Wildfires prevention Environmental engineering	Circular economy has emerged for sustainable management of natural resources aligned with good industrial practices. New-generation fertilisers are an example of industrial synergies and environmental compatibility. The recently revised EU Fertilisers Regulation creates room for development of waste-based fertilisers, as long as their agronomic value and environmental safety are proven. In this sense, there are still on-going discussions at the stakeholders/regulators’ level in order to systematically assess the effectiveness and environmental safety of new waste-based fertilisers. Such discussions are an excellent opportunity for the OHM-E to provide scientific insights on the safe and effective application of local-based fertilisers and turn Estarreja into an example of good agronomic practices aligned with industrial synergies and environmental protection. Biochar is a potential candidate for EU fertilisers. It has raised great interest as a way of managing organic residues through pyrolysis, as well as recycling of carbon and nutrients, thus improving soil quality/productivity. Former (DRuMBEAT) and on-going (MOSAIC) research has proven the merit of biochar in improving Estarreja soil quality. MOSAIC project is currently assessing the cost-effectiveness of biochar production from Estarreja-based byproducts. Coupling of agronomic value with environmental safety of recycling biochar to soils is still lacking in the equation, especially regarding the impact on non-target soil and aquatic organisms as consequence of leaching of potentially toxic compounds. By taking advantage of on-going research and inter-disciplinary networking, SAYFERT research relies in two fundamental axes – pyrolysis and ecotoxicology – for pursuing biochar application rate thresholds that yields trade-offs between agronomic productivity and environmental safety.
