Cellulose •  The most abudant polymer is also: –  Biobased –  Biodegradable –  Recylable

•  Recycling is way make it also sustainable –  CO2 foot print –  Water foot print –  Chemical load

Why to recycle? •  Waste management •  Availability •  Fixed resources in the product •  Competivness

•  Benefits are shown with paper and board –  Typical recycling rates are 4-6 times

•  Environment –  500-1000 times lower water foot print –  GWP for cotton 3,1 and for man-made txt 0,69-0,98 (t CO2 eq./
