There's a growing movement of cities around the world trying to divert waste away from landfills, and San Francisco is leading the way.
San Francisco, California plans to be a zero waste city by the year 2020. What exactly does zero waste mean? Essentially all of the city's garbage will be recycled or composted; next to nothing will go into a landfill.
Recology is the company making this all possible. They're a private company that handles the processing of San Francisco's compost, recycling and landfill trash. All SF residents and businesses are required by law to separate their garbage into these three categories. The law was passed in 2009 with hopes of getting the city closer to that zero waste status.
