The UC Davis campus recycling program aims for zero waste, and, as an example of how thorough this is, they don’t just recycle the usual stuff. Over the past year, UCD purchased more than 150,000 pens, and they’ve partnered with TerraCycle to collect and “upcycle” pens, highlighters and other plastics that normally would have gone in the trash into usable products. TerraCycle awards 2 cents for each implement collected to a charity specified by the university.
