No advertising: Put a sticker "no advertising" on your mailbox, so that it is not addressed with promotional mailings.

 

Scrap paper: Paper, which is printed on one side, can be used as scribbling paper.

Double-sided copying: As often as possible, use both sides of the paper when copying.

Smaller page templates: Through the minimization of document templates a multiple amount of text can be placed on the same amount of paper.
