It's easier to feel less guilty about forgetting your reusable bags for grocery shopping when you plan to use the plastic ones for garbage later. And in turn, it'd be easier to use those plastic bags for garbage if this clever trash bin concept, featuring strategic grooves to accommodate small or multiple bags at once, were a reality.
Unfortunately Hu Lingling and Zhang Baoyi's Eco Trash Can is not, at least not yet. But even if the two can't find someone willing to put their clever Red Dot Design Award-winning creation into production, it doesn't look terribly difficult to hack your own. All you really need is a rectangular plastic bin, a hacksaw, and a series of well-placed grooves to create a compact recycling center, or a convenient way to separate compost from the rest of your trash.
