I can’t believe I never thought of an invention like the Qualy Block trash cans, interlocking stacked bins with openings for paper, plastic, and glass. More than that, I can’t believe that nobody else in the country has — or anyway, I haven’t seen anything like this in the U.S., and I can only find it for sale on Japanese sites. It’s so simple! And yet, for those of us with tiny kitchens, so potentially life-changing!

The modular blocks are designed to easily accept different kinds of recycling, and you could potentially even use one for your regular trash — it’s tiny, but not any tinier than those cabinet-door-mounted trash cans that a lot of people in studios use. OK, screw it, I need this. Who wants to import a couple thousand and open a storefront in Brooklyn? You’d make bank.
