If delivering education in a green manner is part of your initiatives then use
recycled materials in your books. We print books with low VOC toners. Add recycled paper containing at least 30% post consumer waste fiber and a recycled plastic coil binding element and you have a book not only made of recycled materials but one that is fully recyclable.
Reducing paper by putting manuals online or on a CD can be a good way cut printing costs, but beware that these options often fail at providing a tangible, useful on site tool.
