Bedding and blankets generally cover duvets, blankets, bed sheets, duvet covers, pillows and throws.
Pillows and duvets due to hygiene reasons (unless new & unused) should be placed in the general waste bin.
Other textiles such as duvet covers or blankets can be recycled in textile banks.
If you have NEW unused and unwanted items these can be donated to charity.
If you have used ones which are in good condition perhaps you could donate them to an animal shelter.
