Change can be good for San Francisco. The City’s green building codes are creating more energy efficient buildings, solar-ready roofs and electric-vehicle charging stations. But many residents of San Francisco’s high-rise apartments are still expected to sort and haul their trash to different locations in garages and basements. It’s inconvenient, confusing and sometimes impossible. Although almost all apartment buildings in The City compost, according to recycling provider Recology, San Franciscans generally have trouble finding the green bins. Last week, I had dinner with a friend who assured me she had to toss her leftovers in the garbage. Often, this means property managers have hidden the bins behind a locked door or left them unused and unloved in a random alley.
