Want to be less wasteful? If you have paper from your office or home office, save it for another use. Your kids might bring home a lot of one-sided papers from school and they can also be reused. This is especially good if you have kids who like to doodle. Grownups will find uses for it too (to-do lists or shopping lists).
Provide a convenient place to keep your paper and scrap paper. I found this metal file holder at a thrift store. Print out a friendly reminder that says: Scrap Paper for Reuse -One blank side and New Paper-Use sparingly.
