    Sammanfattning : Användningan av engångsförpackningar har ökat kraftigt de senaste åren. Den absolut största delen av dessa förpackningar tillverkars av oljebaserade plaster såsom polyetylen (PE) och polypropylen (PP). Dessa har även en oerhört lång nedbrytningstid, vilket gör det viktigt att finna mer miljövänliga alternativ. LÄS MER
