So of all the strange reporting assignments I’ve had in my life, this has to be way up there near the top. I am sloshing around a food composting plant in the industrial heart of New Jersey, inspecting a small mountain of Terra Chips that has been dumped on the "in-take" floor, alongside Herve Houdre, the general manager of InterContinental The Barclay. The putrid smell of massive-scale food composting is seeping into my clothes. I am cutting quite an attractive image: my baggy brown pants are tucked into enormous yellow rubber boots, and I am scuffling along, trying not to fall down.
Do you ever wonder where your garbage goes? I do. And so does Houdre, which is why he is visiting the Converted Organics composting plant. He is reviewing the garbage procedures at his hotel (excuse me, "waste management," as they say in the biz). Houdre has become obsessed with garbage. Last week, he visited his current contractor's processing center and watched garbage pickers along a conveyor belt sort the refuse into plastics, glass, cardboard, leaving the unsorted trash to be sent along to landfill. It was the first time the plant had seen a general manager; the job is usually the purview of engineers. "Look, there are two issues in the hotel industry: We consume a lot of energy, and we produce a lot of garbage," Houdre said to me on the train out to the garbage plant. "We are addressing both issues."
At his former hotel, the Willard InterContinental in Washington, Houdre says, the amount of trash recycled jumped in two years from 28 tons a year to 135 tons, and the amount of food waste composted went from none in 2006 to 19 tons in 2008. Houdre plans to make the same kind of improvements at the Barclay, which he took over about six months ago.
Today, Houdre is looking at a relatively new process, the industrial-scale composting of food. It's the cutting edge of where garbage recycling is heading, because it means virtually nothing, in theory, goes to landfill. This plant only accepts food (plastic bags really gum up the system), and after about 10 days of "digesting" and processing, what comes out the other end is organic fertilizer that is sold at Whole Foods and Home Depot.
Before donning my fashion-forward yellow booties, we got a briefing from Jack Walsdorf, of the Converted Organics plant, and Christopher Balfe, from IESI-BFC Ltd. and Waste Services, which is the fourth largest waste management company in the U.S. I learned three very important takeaways.
Takeaway 1: To my amazement, I learned that it’s probably better to buy plastic bottled goods than glass bottled goods. I’ve been avoiding plastic soda bottles for the past year, thinking that plastics generally are bad. But it turns out, the value of recycled plastic—plastic today is worth about $400 a ton—is higher than the value of recycled glass. And so it’s more likely that a plastic bottle will get recycled than a glass one. "More than 50 percent of glass picked up off the street goes to landfill," says Balfe, a Cornell School of Hotel Management graduate and recycling consultant, who is helping IESI develop its composting business. "But as the market shifts and prices goes up or down, that will change again."
Takeaway 2: The garbage I carefully separate into plastic, glass, and paper actually does get recycled. I saw the recycling plant—it's Sims Metal Management, which you can read about in this WNYC report from 2008, when the contract was awarded—with my very own eyes, just across the fence from another paper recycling plant. I hope to visit it sometime soon to learn what actually happens to my trash. (Stay tuned for that post.)
Takeaway 3: If a garbage (excuse me, "waste management") company says it is sorting and recycling a hotel company’s garbage, the chances are, only about 15-20 percent actually gets recycled. This is a big deal: an average hotel room in New York City produces 2.2 tons of garbage a year. If only a small percent of that gets recycled, then a heck of a lot is going out to landfill.
Previously in Operation Green Hotel, Do the Right Thing examined the greening of the staff, the hard work of the paper police, and the vagaries of bamboo bedding.
