How many uses does it take for

How many uses does it take for a reusable cup to surpass a disposable paper or styrofoam cup in terms of energy usage? You have to use a single ceramic cup more than 1000 times in order for it to be more energy efficient than using the same number of dispoable styrofoam cups. Of course, this doesn’t take into account anything outside of the manufacturing or washing processes…like the cost of shipping all these foam cups and what happens to them after you’re done with them.
