Ah, the product service system (or PSS): one of TreeHugger's favorite concepts shrouded by one of the clunkiest names. For anyone who'd like a quick refresher, a PSS replaces a product with a service; instead of paying for the product itself (and whatever maintenance and upkeep it requires), you pay to use the product for a bit, and then give it back. Think of it this way: a PSS is often an answer to the question, "Hey, do you really need to own one of those?"
There are a few classic examples: libraries, bike sharing (pictured above), and car-sharing services are all good ones, and we've rounded up a bunch of other good examples in the past. But what makes a good product service system? Read on for a few examples of some newer PSS's that also exemplify why it's better to rent than buy.
