No, unfortunately you can’t recycle wallpaper with your business’ paper or cardboard recycling. Coatings on wallpaper stripped from walls or due to be applied often include dyes, inks, and glues, which are almost impossible to separate from the paper. Such contaminants mean wallpaper can’t go through the regular paper recycling process.
You may be able to recycle new, unused wallpaper if it’s completely paper based and has no coating of any other materials. Sometimes unused wallpaper rolls might class as bulky waste and have to be disposed of alongside other bulky items. There are also eco-friendly wallpapers available made from recycled paper and you can donate leftover wallpaper to charities and other businesses to stay green.
