Supporters say composting helps the climate and enriches the soil while generating energy.
Americans generated nearly 35 million tons of food waste in 2010, according to the EPA, 97 percent of which went into landfills. By contrast, more than 60 percent of the nation’s yard trim — which makes up a similar portion of the U.S. waste stream — got recycled.
Putting grass cuttings and leaves out on the curb, of course, is more palatable than depositing rotting fruit, crushed eggshells and vegetable peelings. And compost collectors have a limited number of places to deposit their hauls, especially in dense urban areas with expensive real estate.
Many communities in the areas have contracts with waste incineration sites, making it harder to develop organic recycling sites.
“The interest is growing, but there’s not enough places to take it and put it,” said Brenda Platt, who promotes composting for the D.C.-based Institute for Local Self-Reliance.
Jack Jacobs, director of distribution of Safeway’s eastern division, said he prefers not to ship it so far away. But it still makes “good business sense” for the company, he said. Safeway pursued composting “because of our environmental sensibility. We knew it was the right thing to do.”
In the past, major trash industry operators such as Waste Management have sometimes fought government requirements to divert waste because they operate landfills, and they get paid according to how much trash they put there. But these same firmsare now investing in organic recycling, in part because of customer demand. Waste Management — the nation’s largest waste hauler, disposal and recycling company — operates 36 organic processing facilities across the country and has invested in companies such as Waltham, Mass.-based Harvest Power, which takes solid waste from municipalities in the United States and Canada and converts it into high-quality soils or energy.
“We certainly believe it’s becoming mainstream, and in some parts of the country, it’s been mainstream for a while,” said Waste Management’s director of organic recycling, Eric Myers, whose firm just opened a state-of-the-art composting facility in Orlando.
Still, Myers said it is too soon to jettison traditional waste disposal altogether.
“Why not ban food waste? Why not ban landfills?” he asked. “Well, it’s not sustainable.”
Government officials overseeing the most successful programs in the country, however, say public policy has played a critical role in boosting organic recycling rates. Back in 1989, California passed a law to divert half of its waste from landfills by 2000. San Francisco has taken it further by diverting 75 percent of its trash by 2010, and now aims to achieve zero-waste by 2020.
San Francisco’s commercial zero-waste coordinator Jack Macy said the fact that the city charges residents and business based on how much trash they generate, known as “pay as you throw,” has helped boost recycling rates.
“We’ve demonstrated in California, and in other places along the West Coast, when we have a low cost of disposal, good public policy makes a huge difference,” Macy said.
Portland, Ore., by contrast, opted in October 2011 to change its garbage collection program so haulers now take away green waste — including food scraps — once a week, but pick up other trash only once every two weeks. In a single year, the city cut its residential trash load by 40 percent.
Not all politicians have embraced this trend: Democrats introduced composting to the House cafeteria in 2007 after winning the majority, only to see House Speaker John A. Boehner (R-Ohio) jettison the policy in 2011 once Republicans regained control of the chamber.
“The good news is that battle doesn’t tell us where the country stands, it tells us where the Republicans are as an ideological mind-set,” said Rep. Earl Blumenauer (D-Ore.).
In some ways composting is a “reactionary” concept rather than “a new idea,” said Jonathan Bloom, author of the book “American Wasteland.” Bloom grew up in Massachusetts, where many residents used to deposit their food scraps in a pail encased in a cement sleeve outside the back door until the early 1970s. They called it “garbage,” and pig farmers picked it up to use as slop.
Sumner Martinson, director of the Massachusetts Department of Environmental Protection’s composting program, remembers putting those scraps outside his parents’ home as a child. Now, he spends his time explaining to state residents why it’s worth composting again.
“It will happen, but it will take a whole lot of education,” he said.
