According to the paper industry, Americans will consume an estimated 23 billion paper coffee cups in 2010. To stem the tide of excessive waste, many coffee houses have begun to encourage consumers to use their own reusable mugs. A study conducted by Sustainability Engineer, Pablo Päster, shows that after 24 uses, a stainless steel mug breaks even with paper cups. Considering that most reusable mugs are designed to be used for 3000 uses, the positive environmental impact of reusables can be enormous.
