My grandmother has an unusual habit. She buys birthday cards for her family and friends, but she never signs them. Why?
So that we can all use them again. And this is not a post-Inconvenient Truth development. She's done it all my life. While, I admit, reusable cards might seem a little odd, reusable envelopes on the other hand sound pretty reasonable ...
And now, finally, Ecoenvelopes has developed a reusable envelope that is approved by the United States Postal Service. For anyone with a home office, this is a nice way to tread a little lighter.
The envelopes zip closed, eliminate the need for a separate reply envelope, and are manufactured with paper from managed forests and contain up to 100 percent post-consumer waste content.
According to info on EcoGeek, every one million ecoEnvelopes used saves an estimated 250 million BTUs of energy and 37,000 pounds of greenhouse gasses.
