The Urban Quest for 'Zero' Waste
Some cities are leading the way in reducing the amount of trash they send to landfills. Here's how they're doing it.
September 12, 2011
After years of burning or burying their waste, some cities are getting serious about garbage.
Across the country, a handful of municipalities are radically reducing the amount of refuse they send to landfills, with the eventual goal of reaching "zero waste." Seattle recycles or composts more than half of what its residents toss out. San Francisco diverts 77% of its waste from landfills. Even sprawling Los Angeles recycles or composts about two-thirds of its garbage.
Those numbers stand in stark contrast to the rest of the U.S., where the Environmental Protection Agency estimates only about a third of waste is recycled or composted. The cities are getting the job done largely by having citizens and businesses sort trash more carefully, to recycle as much as possible.
Officials in these cities think they can go further. "It's good; doesn't mean we stop there," says Tim Croll, solid-waste director for Seattle Public Utilities. "We know the word 'low-hanging fruit' is overused, but there is still more stuff to be gotten out of that waste stream."
Less Than Zero?
The prime benefits in adopting zero waste are environmental; many cities that have enacted zero-waste plans say they have taken up the task in the name of sustainability.
And supporters argue that reducing waste doesn't necessarily mean increasing costs. For cities with limited landfill space—and the higher fees that come with it—most zero-waste activities cost less than normal garbage disposal, says Gary Liss, a zero-waste consultant who has helped about 20 cities form plans to reduce waste.
One caveat: "Zero waste" doesn't necessarily mean " waste." Most cities use a definition from Zero Waste International Alliance, an environmental group, which says that diverting 90% of waste from landfills without the use of incinerators is "successful in achieving zero waste, or darn close."
Why don't cities shoot for 100% diversion? "We're not crazy," says Neil Seldman, president of the Institute for Local Self-Reliance, a nonprofit based in Washington, D.C., that promotes sustainable communities. The closer cities get to that goal, the harder it is to go further, largely because there are so many products out there that just can't be recycled—and people continue to buy them.
Cities can pass ordinances and require households and businesses to recycle and compost, but "they can't control the behavior of residents," says Chaz Miller, the state programs director for the National Solid Wastes Management Association, a Washington, D.C., trade group for the waste and recycling industry. "There is still a lot of material to dispose of in this country, and it's going to remain that way for a long time," he adds.
Indeed, despite increased recycling in recent years, Americans are still prodigious wasters. In 2009, the most recent year for which figures are available, Americans threw out roughly 243 million tons of trash—or about 4.34 pounds of garbage per person, per day, according to data from the EPA. After recycling, composting and incineration, about 132 million tons ended up in landfills that year.
Recycling by the Bay
One of the most comprehensive zero-waste strategies is San Francisco's. The city has relied on ordinances and regulations to prod citizens and businesses into wasting less. In 2009, it became the first city in the U.S. to require food composting for residents and businesses, Rather than throw food scraps and dirty napkins into the trash, individuals and businesses must chuck their organic material into city-provided green bins.
The mandate led to a large boost in compost collection, says San Francisco Department of the Environment director Melanie Nutter. Recology, the city's collection agency, now hauls more than 600 tons of organic waste to a composting facility each day. In an effort to "close the loop," Recology sells the certified organic compost materials.
Along with putting compost in green bins, individuals and companies are expected to sort plastics, aluminum and papers into blue bins and garbage in black "landfill" bins. The less waste residents put in the landfill bin, the less they pay for curbside collection; recycling and compost collection are free. (The system, known as "pay as you throw," is used in hundreds of other cities as well.)
San Francisco's rules don't end there. There's also a mandate for waste at building sites. Construction and demolition crews must recycle or reuse at least 65% of the material from a site, which involves sorting all debris or ensuring it is hauled to a collection facility.
The result of all these efforts is a waste-diversion rate of 77%—the nation's highest—and the city is aiming for 100% by 2020. Ms. Nutter says the city can reach 90% if it prods its citizens to be even more waste-conscious; about a third of the waste that San Francisco sends to the landfill is recyclable, and another third is compostable.
Officials in San Francisco say sustainability is the driving factor behind its push for zero waste. The city pays for garbage collection only from city buildings and property; residents and businesses pay for their service through fees. The city says residents pay about the same for curbside trash service as in nearby cities.
Shades of Green
Another zero-waste leader is Seattle, which diverts about 54% of its waste from the dump and hopes to reach 70% by 2022. The city mandates recycling for businesses and residents, and requires food composting for single-family residences.
It has also banned the food-service industry from providing goods in plastic-foam containers, and requires single-use packaging—including plates, coffee cups and utensils—to be recyclable or compostable. Among the approved alternatives on the city's website: drink cups made from corn, bowls made from tapioca starch and wooden utensils.
Still, not all high-achieving cities get there with mandates and bans. Los Angeles diverts over 65% of its waste from landfills and is shooting for 70% by 2013. But it doesn't mandate recycling. "We don't believe in banning, as a city," says Alex Helou, assistant director of the city's Bureau of Sanitation.
Mr. Helou says the bureau encourages residents by giving prizes like Starbucks gift cards to neighborhoods that increase their recycling the most. He says the city has also sought to make recycling as convenient as possible and has expanded the type of waste that consumers can throw into recycling bins to include items like plastic foam and milk cartons.
Austin, Texas, currently recycles or composts about 38% of its waste and is in the process of finalizing its zero-waste plan. In addition to considering a recycling mandate, the city has pursued an original outreach campaign. Earlier this year, "Dare To Go Zero" premiered on the city's public-access channel. The "Biggest Loser"-style reality show challenged four families to reduce their waste by 90% over the course of five weeks.
The city's director of solid-waste services, Bob Gedert, says Austin hopes to ratchet up its diversion rate to 75% by 2020 through a mix of regulation and outreach, but says the city does not expect to reach zero waste until 2040.
Incinerate or Innovate?
Some in the municipal solid-waste business don't believe that recycling and composting can reduce a city's waste down to nearly nothing. Their suggested alternative: incinerating vast amounts of trash to convert it into energy. Not only does burning turn the trash into something useful, they say, but it's also a much cleaner process than it was 30 years ago. Los Angeles's Mr. Helou says the city believes it can hit 85% through proper sorting but would consider incinerating waste to produce energy.
Officials in San Francisco, like many other zero-waste supporters, maintain that incinerating waste increases greenhouse-gas emissions, and note that incineration destroys, rather than conserves, resources.
Still, many city officials agree that some sort of technological help will be needed as they get closer to zero waste. Seattle's Mr. Croll says he is interested in anaerobic digestion, a process where micro-organisms break down organic waste and produce methane, which can later be used for energy. San Francisco is hoping to rely on advanced mechanized sorting systems that pick more recyclables from the garbage flow, Ms. Nutter says.
After that, she says, it may be out of the city's hands. "There are some items in the waste stream that can't be recycled or reused or repurposed," she says. "So, in that case, we think the last 10% will really come down to working with manufacturers" to reduce and rework materials packaging.
Mr. Liss, the zero-waste consultant, says that at some point cities have to say, "We've done a lot with recycling, but we need to do a lot more with reducing and reusing."
San Francisco hopes to divert 100% of its waste from landfills by 2020. An earlier version of this article incorrectly said the city hopes to divert 90% by 2020.
