SENIORFORSKER, AQUATEAM COWI

Maria Estevez er kjemiingeniør med 10 år erfaring innen miljøkjemi og biogassprosess.

Hun begynte å jobbe hos Aquateam COWI i mai 2014. Før dette var Estevez ansatt som forsker ved NMBU fra 2009 og siden som post-doktor forsker ved Bioforsk (i dag NIBIO), Jord og miljø fra 2013. Før hun flyttet til Norge, utførte hun forskning i Danmark, gjennom Aalborg Universitet, på danske sentraliserte biogassanlegg, og har også erfaring fra arbeid i Uruguay som miljøkjemiker i vann-og avløpsvannsområder.

Estevez har en spesialisering innen anaerob nedbrytingsprosesser og prosessoptimalisering, forbehandling av avfallsfraksjoner for biogassproduksjon og samråtning av forskjellige organisk og lignocellulosic biomass fraksjoner. Hun har også erfaring innen forbedring av utråtnet slam (biorest) som gjødsel, kjemi og teknologivitenskap om gjenvinning av næringsstoffer (fosfor, nitrogen og kalium) fra avløpslam eller utråtnet slam.
