  • Regular, petroleum-based plastic doesn't biodegrade. But this year's crop of Earth Day — inspired ads shows plant-based plastics doing just that: an empty SunChips bag fading into the soil, a Paper Mate pen dissolving underground. Although the visuals suggest that these items simply disintegrate (Goodbye, landfill!), the reality is more complicated. Take the SunChips bag. It needs to go in a compost bin; the packaging is clear about that. Likewise, Paper Mate notes that the pen's outer casing will break down if buried in a backyard but that its innards should go in the garbage. Forget to separate them, and the outer part won't biodegrade in a landfill./.../
