Old story alert, but I believe that it is still worth noting that the city of Edmonton was forced to shut down its fancy composting facility because the roof rotted. What caused that, you may ask. Well, that would be the effects of composting, natch.
The city announced Wednesday that, effective immediately, the Edmonton Composting Facility is ceasing operation and shutting down due to the roof being structurally unsound.
The facility, which opened in 2000 and was considered state-of-the-art at the time, was the largest of its kind in North America by volume and size, according to the city. But the heat and chemicals from the aerobic composting process has caused the roof to rot away.
