Q. Dear Twig: Where do the burnt black French fries that I throw out at a restaurant go?
A. Probably into a hole in the ground. Here's their trip, in a nutshell:
The trash in the can gets dumped with a flump in the back end of a garbage truck. The garbage truck drives to a dump, a landfill. The trash gets dumped in the dump, pa-dump. The trash and the burnt black fries in the trash get buried by tons of more dumped trash. The fries get cut off from oxygen, gak! But anaerobic ("an-air-OH-bik"; no oxygen) microbes jump in. They decompose the fries.
The problem: Anaerobic decomposition — of burnt black fries, apple cores, muffin stumps, etc. — gives off methane, a strong greenhouse gas. And greenhouse gases, at too-high levels, can make Earth hotter and cause global climate change. Scientists say that's happening now. They say we should do things to slow down or stop it.
Next: A thing we can do with those fries that can help!
P.S. How big's the problem? The U.S. alone dumps some 26 million tons of food trash a year.
The figure of 26 million tons a year comes from the Ohio Compost Association (OCA). The group is helping sponsor a conference on the topic June 27. A press release on it by Twig's little friend is here: http://www.ag.ohio-state.edu/~news/story.php?id=4679. The conference Web site: http://www.ohiocompost.org/Conference.html. The conference title: "Create a Diversion."
Also check out the Compostable Organics Out of Landfills (COOL) 2012 campaign, http://www.cool2012.com/, whose name spells out what it thinks we should do and by when it thinks we should do it.
