Tähtsamad tulemused
2023. a tulemused:Haisuhäiringu analüüsiks linnaalal teostati kanalisatsiooni õhu ja vee koosvoolamise numbriline modelleerimine suuremõõtmelise torustiku näitel. Modelleerimise tulemused annavad ülevaate õhuvoolu dünaamika keerukusest halvasti ventileeritud torustikus.BIO-PLASTICS EUROPE projekti raames loodi poliitikaraamistik, et illustreerida, kuidas projekt aitab kaasa ELi poliitikasoovitustele biopõhiste plastikute käitlemiseks mänguasjade, söögiriistade, pakendite, põllumajandusliku mulšikile ja veevarustuse kasutusvaldkondades
