On the drive back from Kentucky, as we drove through Ohio on I-71, I noticed a large landfill by the side of the interstate. We had been driving through very flat country for a while, and we were far from most civilization. Obviously the most important considerations in the sighting of this landfill were to get it as far away from people as possible, while keeping it highly accessible to the trucks that bring the garbage in. However, since the landfill was so far from civilization, I could see (but failed to photograph) that they just burned off the methane that came from the garbage, from a large black tube. Based on the size and visibility of the flame, it seemed as though they had a fair amount of methane output from the landfill. This was plain evidence that there are positives and negatives to many landfill sightings; in this case, the garbage wasn’t in anyone’s backyard, but it was too far away to capture energy that could be harnessed from methane output.
