A broken window over Labor Day weekend has lead to threats from the city of San Francisco to restrict access to the sinking Millennium Tower; now, engineers are scrambling to figure out whether the problem was an isolated incident.
San Francisco’s color-coded trash bins — the black, the blue and the green — marked a breakthrough in waste reduction when they hit the curbs nearly two decades ago. Now, the pioneering program that encouraged residents to separate their recyclables and food scraps from their garbage is headed to a whole new level. City officials want people to generate no garbage at all, or at least as little as physically possible, and they’re asking the rest of the world to join their cause. The ambitious zero-waste initiative, which would cut greenhouse gas emissions from landfills, will be promoted on the international stage next month when San Francisco hosts the Global Climate Action Summit.
