If they were smart, they would capture the methane and use it as a fuel.  I
have seen a few municipalities that take their methane from the landfill and
pipe it in to use as a fuel source...think of all the natural gas they don't
have to purchase.  Previously, they would just burn it off...not sure what
the by-product of burning methane is, but I guess if it is going to get
released anyway, it is better to get some use out of it and not have to use
other resources as a result

Ooops! Biodegradeable products release methane which is more potent than CO2
as a greenhouse gas

Excerpt:

Research from North Carolina State University shows that so-called
biodegradable products are likely doing more harm than good in landfills,
because they are releasing a powerful greenhouse gas as they break down.

"Biodegradable materials, such as disposable cups and utensils, are broken
down in landfills by microorganisms that then produce methane," says Dr.
Morton Barlaz, co-author of a paper describing the research and professor
and head of NC State's Department of Civil, Construction, and Environmental
Engineering. "Methane can be a valuable energy source when captured, but is
a potent greenhouse gas when released into the atmosphere."

And the U.S. Environmental Protection Agency (EPA) estimates that only about
35 percent of municipal solid waste goes to landfills that capture methane
for energy use. EPA estimates that another 34 percent of landfills capture
methane and burn it off on-site, while 31 percent allow the methane to
escape.

"In other words," Barlaz says, "biodegradable products are not necessarily
more environmentally friendly when disposed in landfills."

This problem may be exacerbated by the rate at which these man-made
biodegradable materials break down. Federal Trade Commission (FTC)
guidelines call for products marked as "biodegradable" to decompose within
"a reasonably short period of time" after disposal. But such rapid
degradation may actually be environmentally harmful, because federal
regulations do not require landfills that collect methane to install gas
collection systems for at least two years after the waste is buried. If
materials break down and release methane quickly, much of that methane will
likely be emitted before the collection technology is installed. This means
less potential fuel for energy use, and more greenhouse gas emissions.
