New York City Turns to Composting


In 2011, the United States produced 250 million tons of municipal solid waste, 56% of which was compostable materials. In New York City alone, more than 10,000 tons of trash is collected every day and shipped to landfills where organic materials decompose. Methane, a greenhouse gas 25 times more powerful than carbon dioxide, is produced as a result of the decomposition. Behind industry and agriculture, landfills are the third-largest source of methane in the United States. New York City’s Mayor Michael Bloomberg recognized this major environmental concern in his State of the City address, and called for food waste recycling, the city’s “final recycling frontier”. Of course New York City isn’t the first to come up with such an ambitious plan. Cities such as San Francisco, Seattle, San Antonio, and Portland, Oregon have been composting as early as 2009. Today, San Francisco mandates that all residents separate organic material, adding a third bin to trash and recycling. The compost bins can include all food scraps, along with vegetation and solid paper products such as coffee cups and milk cartons. Overall, 78% of San Francisco’s waste is now diverted from landfills.
