A recent study figured out how many times you needed to reuse a reusable cup before it actually begins to save energy and resources in comparison to using a throwaway paper cup. When comparing a typical paper coffee cup, it found a reusable ceramic mug would need to be used 39 times before you begin to see environmental savings, a plastic thermos would need to be used 17 times and a heat-resistant glass mug just 15 times. What's taken into consideration is the amount of materials and resources needed to make a reusable cup, plus the amount of water and energy to wash it. So the lesson is simple: Buy one reusable cup and use it over and over.
