Thinking positive about waste from all spectrums of product is an important aspect of design. DBA does penmanship right with their 98 Pen. "The DBA 98 Pen is the only 98% biodegradable pen in the  world. It’s also the only pen to use ink composed of simple,  pronounceable ingredients. Produced at a wind-powered  facility in the United States, it was designed as a responsible  alternative to the wasteful and often toxic pens we use almost every day. And with its straightforward design and rollerball tip, the DBA Pen looks good and writes well, too." A three pack of these will run you about 9$US. (iainc)
