End user education is important. You have done the hard work to minimise the environmental impact of your publication. Make sure your audience is aware of this. When they are finished with a publication encourage them to circulate it to others or dispose of it in an environmentally friendly way.
Make sure you note that your product is printed on a percentage of (eg, 100%) recycled paper with mineral free inks.
An example of text you can use is:
“This publication is printed on 100% recycled paper using vegetable based inks.”
(Remember to confirm the supply of the stock and ink before committing the statement to prepress)
Add a suggestion that the product is disposed or reused.
For example:
“At the end of use please recycle this publication.”
“Please pass this on to others to use.”
“This publication has been designed to be recycled. Please recycle when you are finished with it.”
