About this factor

From Syke

Pohjoiseurooppalaisia (Suomi, Ruotsi, Viro) salaoja- ja hulevesikäyttöön tarkoitettujen rumpuputkien valmistajia on ainakin Uponor, Pipelife, Meltex, Wavin ja Krah Pipes, jotka ovat julkaisseet EPD:itä tuotteillensa. Tarkempaa tietoa eri tuotteiden markkinaosuuksista ei kuitenkaan ole. Arvioidaan, että näiden valmistajien kaikkien rumpuputkien EPD tietojen keskiarvo kuvaa tyypillisen Suomessa käytettävän rumpuputken päästöä. Laadintamenetelmä: Vertailu ja valinta.
