A classic, harmless landmark as you enter the city from the south? Far from it!

Wheelabrator’s smokestack is recognizable, but many don’t know that it is part of the city’s largest air polluter. In operation since 1985, Wheelabrator Baltimore is the 10th-largest trash incinerator in the country, and accounts for 36% of all air emissions from Baltimore City industry – three times worse than the second-largest polluter. In fact, Wheelabrator ranks

#1 in Mercury – causes damage to nervous, digestive, and immune systems, lowers IQ in children
#1 in Hydrochloric Acid – irritates eyes, skin, and nose, damages lungs
#1 in Sulfur Dioxide – triggers asthma attacks, increases lifetime risk of chronic respiratory and heart diseases and stroke
#1 in Lead – causes damage to nervous system and kidneys, lowers IQ in children, increases likelihood of antisocial behavior
#1 in Nitrogen Oxides – triggers asthma attacks, increases lifetime risk of chronic respiratory disease and stroke
#1 in Formaldehyde – irritates eyes, skin, and nose, increases lifetime risk of cancer
#1 in Carbon Monoxide – causes headaches and dizziness; increases lifetime risk of heart disease

And from a climate change perspective, Wheelabrator is #1 in Carbon Dioxide emissions!

But how can this be? Most days, you never see anything coming out of the smokestack.

This is because Maryland law states that incinerators cannot release visible emissions. People usually don’t complain about pollution if they can’t see it, so Wheelabrator’s impact, ironically, is out-of-sight, out-of-mind.

But what do those rankings really mean?

One of the best ways of understanding how impactful Wheelabrator’s emissions are is to compare them to mobile emissions and other sources.

So how does Wheelabrator stack up against other sources?

Let’s start with nitrogen oxides (NOx). Once more, NOx is a pollutant that triggers asthma attacks and increases the lifetime risk of heart disease and stroke.  We made a graph comparing emissions from every source that emits NOx using data from 2014 – the most recent data available.

What this graph shows is that when you combine all mobile sources, they release 75% of the NOx in Baltimore’s air each year. But Wheelabrator, one smokestack, puts out more than NOx than every other stationary industrial source (“All Other Point Sources”) of pollution in Baltimore City combined.

So, that’s Wheelabrator vs. everything. But let’s crack open that “Mobile Sources” piece of the doughnut graph…

Well, that looks a little different. The green section is “Onroad non-Diesel Light Duty Vehicles” – what a mouthful. Think of those as the typical Toyota Corollas, Nissan Sentras, and Chevrolet Impalas (Dante’s car). The “Onroad Diesel Heavy-Duty Vehicles” are things like the big 18-wheelers you try to avoid as they come off the on-ramp. “All Other Mobile Sources” are special types of cars/light trucks/SUVs.

The graph shows Wheelabrator’s NOx emissions are so large, closing the facility would be equal to taking over half the cars off Baltimore’s roads, or just under half the long-haul trucks off Baltimore’s roads. Whew, what a polluter!

Let’s talk another pollutant now: sulfur dioxide (SO2).

Once again, like NOx, it triggers asthma attacks, and contributes to the increased likelihood of heart disease and stroke. It also contributes to ground-level ozone and the formation of particulate matter. You probably are thinking the results in the next graphs will be about the same as the NOx ones above, right? Well…

That’s quite a difference! Wheelabrator’s SO2 emissions are almost half the total SO2 emissions in the entire city. 

And if we crack open the “Mobile Sources” piece again…

Wooooah. That is insane. First, you can see that cruise ships (among other vessels) aren’t as wonderful as they may seem (and the viruses probably prove that too.) But if we’re talking cars and trucks, Wheelabrator’s SO2 emissions are 8 times worse than all the trucks and the Corollas, Sentras, and Impalas combined. 

Let me say that again. Every year, Wheelabrator’s ONE smokestack puts more sulfur dioxide in Baltimore’s air than all the cars and trucks on our roads EIGHT TIMES over. 

Something has to be done, and that something is shutting down Wheelabrator once and for all!
