Not using unnecessary store bags

4 B. …Reuse… Buying products that last longer
Dish towels instead of paper towels The old coke glass bottles that were returned to the store, washed, and reused.

Photodegradable plastic – made so that when it is left in the sun for many weeks, it becomes brittle and breaks into pieces.

9 C. …Recycle Degradable Plastics
Green plastic – Made by blending plant sugars with a special chemical agent. Requires 20-50% less fossil fuels Degrades within 45 days of being thrown away (bacteria break it down)
