Reuse

Reusing unwanted items reduces the amount of finite raw materials we consume and reduces disposal costs.

Collect paper that has been used on one side and reuse as note paper
Reuse envelopes by sticking a label over the old address and postmark
Use internal mail 'ladder' envelopes for internal post
Use outdated letterhead for in-house memos
Reuse file folders
Purchase two-hole ring binders so they can be reused more easily. Most hole punches only have two holes.
Purchase good quality stationery and IT equipment that is durable and will last a long time
Purchase refillable pens and pencils (rollerball pen cartridges and pencil leads cost less than buying a pack of pens/pencils)
Donate good quality unwanted materials to your local art scrapstore, such as Orinoco
Donate unwanted office furniture and equipment to other departments or to external organisations
Buy a thin cotton bag that you can keep in your bag or pocket to use for shopping at lunchtime or after work
