Reduce, Reuse, Recycle.
According to WRAP (http://www.wrap.org.uk/), up to 80% of the waste sent to landfill by offices is paper. By using the 3 R's of environmental awareness, you can cut the amount of paper wasted by your company to almost nothing.
Reduce: do you really need to print that? Could you email a memo rather than circulate paper copies?
Reuse: make sure your staff always print on both sides of a sheet of paper. Think about using old sheets you don't need any more to make "scrap pads" for note taking - make sure there's no sensitive information on the other side, though.
Recycle: Paper recycling bins from Glasdon are an attractive option that will suit any workplace, gathering large amounts of waste paper securely and discreetly. For sensitive data, consider a Confidential Paper Recycling Bin with a keyed lock.
