At one point there was no where to recycle duvets, pillows and bedding, but now Dunelm has started collecting these items to reuse and recycle. Woo!
Not only do they take duvets, pillows and sheets, they also take towels, bath mats, shower curtains, cushions, curtains, table cloths, blankets and throws. Check out their website for more details.
The only condition for them to be recycled and that is the items have to be clean
You can find a recycling box in Dunelm to deposit your items.
