Yes, You Can Recycle Your Pizza Boxes

When Eric Nelson looks back on his years as a thriftlessness reduction coach at the University of Kansas, what stands out are the pizza boxes. “ One year, there was a first-week consequence for all the clubs and organizations, ” he told me on a phone call from Lawrence. “ I think Pizza Hut sent over like 500 medium one-topping pizza. ” That was great for the hungry college students, not so much for Nelson, who spent the evening schlepping 500 pizza boxes to the dumpster “ because we could n’t recycle pizza boxes. ”
It ‘s advice from the dawn of curbside recycle : Do n’t put your pizza corner in the blue bin because the greasy cardboard and cheese scraps make it unrecyclable. For years, conscientious recyclers followed this advice, and tens of billions of pizza boxes were sent to landfills and incinerators. The intentions were good, but it turns out that the advice was n’t. New research reveals that, so long as you remove all the pizza, the cardboard container that held your Veggie Supreme can be readily recycled into something new .
That ’ randomness good news, because all those pizza boxes add up. A one dormitory floor at the University of Kansas, says Nelson, might go through 20 to 30 boxes during a single party. According to new research from WestRock, one of the earth ‘s largest paper and packaging companies, 3 billion pizza boxes are sold in the United States annually. all in all, they weigh 600,000 tons—the equivalent of 53 Eiffel Towers. If they were all recycled, they would account for 2.6 percentage of the reclaimable cardboard generated in the US annually .
Pizza boxes have not been deemed reclaimable in the past because grease and tall mallow, when added to a atomic pile of cardboard cook for recycling, are not precisely quality enhancers. A stack of clean, broken down Amazon boxes can be recycled into newfangled boxes that meet the forte and color specifications of, say, a large e-commerce party. The concern was that cardboard infused with mozzarella or marinara could weaken or discolor the paper or cardboard into which it ‘s being recycled. Consequently, some paper mills refused to accept pizza boxes, and recycling programs that service those mills—such as the one at the University of Kansas—prohibited them besides.

It turns out, however, that such prohibitions are far from universal. In fact, they are relatively rare. According to WestRock, 73 percentage of the US population has access to recycling programs that accept pizza boxes. And a holocene sketch of companies that belong to the American Forest & Paper Association found that pizza-box acceptance is nowadays about cosmopolitan among companies that manufacture from recycled cardboard.

That ’ sulfur because, as WestRock ’ second study found, cheese and dirt “ at typical levels “ do not impact the quality of paper and cardboard manufactured at mills using recycle materials. Technology gets some of the accredit : Over the years, newspaper mills have become more ace at screening out chunks of tall mallow during the pulp process. meanwhile, it turns out that it ‘s the very rare mill that receives pizza boxes in a volume large adequate to impact its end products. As a consequence, the AFPA barely responded with newfangled industry guidance : pizza boxes are reclaimable. Consumers need only make certain that they empty the boxes of stray slices and crust, plus any wimp wings, sauce containers, pizza savers, and anything else that might be left inside. ( Pizza savers, those little three-legged fictile tables that keep the cheese from sticking to the top of the box, are sadly excessively minor to be recycled. ) There is no longer any excuse to hold onto this oldest, and most park, of recycling myths .
This is major news for recycling advocates. Pizza boxes are n’t the biggest cut of the american recycle pie, but they ‘re an under-utilized resource, and dispelling the myths around their disposability will boost sustainability efforts from college campuses to anywhere hunger strikes .
For Eric Nelson, now president of the Kansas Organization of Recyclers and a man who has trashed more pizza boxes than most, the news is personal. “ I ‘m a trash swot, ” he proclaimed. “ And this is the most exciting matter to happen in my airfield in years. ”
