New York City's trash dilemmas—and opportunities 27 April 2021, by Russ Kuhner During the COVID-19 pandemic, the city has seen increases in household garbage produced by New Yorkers under lockdown. Meanwhile, a pandemic- related city-budget shortfall resulted in a $106 million cut in the Department of Sanitation's budget that led to a city-wide waste pile-up. I engaged Cohen in some "trash talk," discussing shifting trends in how the city has dealt with its garbage, and what could be done to equitably improve its environmental impact. The following interview has been edited for clarity and length. When did you first notice that waste management was a problem in New York? The section of Brooklyn where I'm from is called Bags of trash and recycling spill out onto a New York Flatlands, and a lot of Flatlands is actually landfill. City street.

The reason they had to stop Steven Cohen has been working to improve waste using them is that they had gotten so high, they management both at the federal and local level for were concerned it would interfere with navigation over 40 years. into Kennedy Airport. Hired by the U.S. Environmental Protection Agency When I was growing up, I saw those landfills.

In addition to being a lifelong New Yorker, Cohen What then drew you towards waste has co-authored three books and authored management professionally? numerous articles detailing New York City's solid waste management challenges and strategies When I was in graduate school in Buffalo, the toxic since the closure of its last landfill, Fresh Kills, in site at the Love Canal became a political issue.

That made me aware of the on air quality, and I think now that we're going into problem there. the decarbonization era, we're going to have renewable energy and electric cars. There'll be far By coincidence one of my professors, Marc less air pollution than there was before, and that's Tipermas, was on Jimmy Carter's transition team all the application of technologies. and he hired me to go work in EPA while I was still in graduate school, first in the water program and With a mayoral election coming up, do you see then eventually in the Superfund program, where an opportunity for a new administration to make he was the head of policy analysis. progress on this issue? In 1981, you returned to New York City to work Well, I think Mayor de Blasio hasn't paid any at Columbia. How did you engage with waste attention to it, so you couldn't do much worse. They issues through your work at the university? did pick up the food waste, and then he ended it when the pandemic started. Early in 2001, I worked with an engineering colleague, Nick Themelis, and we did an analysis When Bloomberg was mayor, at first, he also shut on what to do with New York City's waste after down recycling, but then after a couple of years he Fresh Kills closed later that year. The rollout of our started to understand the importance of proposal and its visibility got obscured because we sustainability, and so things changed. I think in were going to release it in September of 2001, but most elections, it's not a particularly hot issue. But I something else happened in September of 2001 think at some point, this issue comes back because that got a lot of attention for good reason. So, we you have to do something with the garbage. didn't release our report until January. When you export all of your garbage to landfills and It got less attention than it should have. New York to facilities that aren't under your control, you're at City now exports all of its garbage, and the issue is the mercy of the market. If the landfill in Alabama waste transfer stations. All the garbage must be wants to raise their tipping fee, you have to pay it. taken from the garbage trucks to waste transfer That's an uncontrolled cost the city really doesn't stations, where it is shipped out of the city, and want. nobody wants waste transfer stations in their neighborhood. In the time that you've lived in the city, have you seen changes in everyday New Yorkers' I've read that you were appointed to the EPA's relationship with garbage?

They work? had a whole campaign where they said a cleaner New York is up to you. They would put up little It's really one of the places where I learned how posters just to get us to throw trash into garbage quickly the technology of pollution control was cans. Over time, of course, there's more of an 2/4
emphasis on source separation and things like that, able to have the whole facility built that way. but you know New York is a very fast-paced place and people don't often pay that much attention to The issue would still be though the value of the the garbage and to the waste treatment. land. It still might be too expensive to do it that way, but what I was attracted to is then every community At the household level, there's been a lot of would have its own, and so the issue of equity change. There's been an increase in recycling. For wouldn't come up because you have to treat your a while, although they've stopped it for now, they own garbage. The argument would be that it might had food waste recycling, and about half a million be more expensive, but it might not be. people were doing that. There's been some greater attention paid than before. When reading that waste-to-energy plants can reduce waste sent to landfills by 90%, turning it In general, the cost of waste disposal has gone up, to ash, it seems like this technology is the largely because we have to transport it and bring it future. someplace. But the other thing is that the value of land in New York City has gone up. Things that we You could also use the ash as construction material used to do in New York when it was a for streets and for sidewalks. The problem with manufacturing city, you would never do now waste-to-energy is that if the plant isn't well-run, it because the land is simply too valuable. can pollute. You can have dioxin emissions from the stack. You have to work really hard to make The cost of transporting the waste is still probably sure that it's under control. cheaper than the cost of land. One thing I wrote in an op-ed in the Times, maybe 15 or 20 years ago, Locally, We Act, a community-based was what we really ought to do is barge the waste environmental justice organization in Harlem, up to river towns in New York that were depressed, and nationally, the Sierra Club, have come out like Poughkeepsie and Peekskill, and build for them against the combustion of waste. However, the a waste-to-energy plant. In return for giving them New York League of Conservation Voters states free garbage disposal and energy, we would have a that waste-to-energy could be a viable option cheaper place to bring the garbage. for waste management. Politically, of course, nobody wants New York City's In Japan they've developed a way to treat garbage garbage, so that was never going to go anywhere, where you don't burn it, you chemically transform it. but I think environmentally it was probably one of It's still pretty expensive, but there's no stack. the better ideas. Essentially you break down the chemical content of the garbage and you can still generate some In your 2008 article for the Observer, titled energy from it, but there's no combustion. "Wasted: New York City's Giant Garbage Problem ," you proposed a similar solution that would What you really want is something where the raw equitably distribute waste-to-energy plants materials inside the garbage are pulled out so that throughout New York City so we could manage you can develop a circular economy. When burning our own waste. garbage, you end up taking finite resources and destroying them. It turns out, now with computers, cheap communication, and cheap information, you could A more sophisticated way would be to mechanically actually have 59 waste-to-energy plants in every and automatically separate the different community board in the city and have it controlled substances. The stuff that's most usable, you use, in a control room in downtown Manhattan. You and the stuff that isn't, maybe you would burn. could completely automate it, maybe one or two people working in each place. In 10 to 20 years Combining municipal waste facilities with from now, using artificial intelligence, you might be amenities, like the state park on top of the North 3/4
River Wastewater Treatment Plant, seems like an encouraging way to expand newer technologies into dense cities like New York. We've built a water filtration plant underneath a golf course in the Bronx in the last decade. The community didn't like it, but now it's there and it's hard to know it's there. I think you'll see again, through the use of technology and design, there are ways to make these noxious facilities less noxious. By creating amenities, even Fresh Kills is going to become Staten Island's major regional park. It'll be like Prospect Park, or Van Cortlandt or Central Park. That's going to be Staten Island's park in 20 years. It's a huge expanse of land, and once they get enough separation between the toxics and the people, it'll be a very popular place to go.
