”Outotecin ja Ecolan Oy:n yhteinen FULLREC-lietteenkäsittelymenetelmäsaavuttivat jaetun ensimmäisen sijan Ravinnekierto Challenge -ideakilpailussa.

Alan toimijoiden mukaan ravinnekierron tehostuminen on mahdollista ennen kaikkea

kannattavan liiketoiminnan myötä.”

” FULLREC - RATKAISUssa, yhdyskuntien jätevesien lietteestä ja energian

tuotannon tuhkista saadaan talteen ravinteita myytäviksi lannoitetuotteiksi.

Ehdotus yhdistää kolme aiemmin erillistä teknistä prosessia. Mädätettyä yhdys-

kuntajätteen lietettä ei perinteiseen tapaan polteta kokonaan, vaan kuivataan

ja sekoitetaan tuhkaan – seos rakeistetaan ja pystytään kuljettamaan kustannus-

tehokkaasti pitkänkin matkan päähän esimerkiksi metsien lannoittamiseksi. ”

Tulevaisuuden ratkaisu ravinteiden kierrätykseen – 60 …100 % fosforista, typestä ja kaliumista uudelleen käyttöön lannoitteiden valmistukseen ja myös pääosa hiilestä takaisin metsiin ja pelloille
