Tips From Planet Green
Here is a useful article from Planet Green.
Use Green Materials.
Some paper use can’t be avoided, so use recycled paper and envelopes that have been processed and colored using eco-friendly methods. Pens and pencils can also be made of recycled materials, and refillable pens and markers are preferable to disposable ones. Use biodegradable soaps and recycled paper or cloth towels in the bathroom and kitchen, and provide biodegradable cleaners for the custodial staff. Buy in bulk so that shipping and packaging waste are reduced, and reuse the shipping boxes. Recycling printer cartridges is often free, and recycled replacements are cheaper than new ones.
