When you throw leftovers in the fridge, they end up in the trash far more often than in your stomach-a dilemma that some conscientious restaurant-goers solve by leaving their doggie bags on top of city garbage cans, where the homeless can find an easy free meal. Josh Kamler and Axel Albin, owners of a San Francisco design studio, would like to take this practice mainstream. They've come up with a catchy name ("replating"), a website, and a logo not unlike the now-ubiquitous recycling icon. Kamler says, "If you throw your beer bottle in the garbage, people are like, ‘Dude, you're not going to recycle that?' We hope the idea of replating will get to such a place in the culture that people will say, ‘Hey, you're not going to replate that?'"
