CARY — The town of Cary would like to know why its five tons of processed human waste caught fire on Wednesday.
After all, this stuff is somewhat valuable. The town of Cary doesnt go to the trouble to strain bio-solids out of its sewage and dry it into tiny nuggets just so it can catch fire in a silo, like it did Wednesday.
Normally, the town of Cary would sell its populations processed poop as Cary Enviro Gems, a Class A fertilizer of exceptional quality, according to the towns website.
It turns out that Cary Enviro Gems burn pretty well, too. The mysterious fire, discovered at about 11 a.m., smoked for about four hours at the South Cary Water Reclamation Facility.
Workers evacuated as a built-in fire-suppression system pumped nitrogen dioxide into the indoor silo to smother the flames, but the stubborn fire wouldnt be snuffed easily.
Ultimately, the Cary Fire Department shoveled five tons of smoldering material into a huge bin. That represents only a fraction of a percent of the 6.2 million pounds of little gems that Cary produces every year.
And, no worries, the town will simply reprocess the burned pellets, good as new.
The fire posed no public danger and didnt smell bad, according to town spokeswoman Carrie Roman. It does not appear that the fire did any significant damage to the silo, either, but the cause remains a subject of study.
