Replacing Pipeline Is Safe Bet On Sept. 25, Al Monaco, president and CEO of Enbridge, addressed members of the Northern Michigan Chamber Alliance. His message was, “I want to be clear. We wouldn’t be operating this line if we didn’t think it was safe.”

We pretty much have to take him for his word...

Know The Root Of Activism Author and rabbi Harold Kushner has said, “People become activists to overcome their childhood fear of insignificance.” The need to feel important drives them. They endeavor good works not to help the poor or sick or unfortunate but to fill the void in their own empty souls. Their various “causes” are simply a means to an end as they work to assuage their own broken hearts...

Climate’s Cost One of the arguments used to delay action on climate change is that it would be too expensive. Such proponents think leaving environmental problems alone would save us money. This viewpoint ignores the cost of extreme weather events that are related to global warming...

A Special Edition Cuckoo Clock The Republican National Committee should issue a special edition cuckoo clock commemorating the great (and lesser) debates and campaign 2016...

Problems On The Left Contrary to letters in the Oct 5th edition, Julie Racine’s letter is nothing but drivel, a mindless regurgitation of left-wing stuff, nonsense, and talking points. They are a litany of all that is wrong with the left: Never address an issue honestly, avoid all facts, blame instead of solving; and when all else fails, do it all over again...

Thanks, Jack It is so very difficult for the average American to understand the complex issues our country faces in far off places around the globe. (Columnist) Jack Segal’s career and his special ability to explain these issues in plain English in many forums make him a precious asset to all of us in northern Michigan...

The Smell of Money: Pumping gas from landfills

Harley Sachs - August 11th, 2005
Here in the U.P we used to call them
bear pits. They were the open garbage dumps where tourists occasionally would try to
put their kiddies on the backs of hungry
wild bears in the hopes of getting that great souvenir photo, sometimes with unhappy results.
Turns out that calling our dumps bear pits was a misnomer. The proper name for what are
now officially sanitary landfills is money pits. Not only can municipalities reap substantial rewards from tipping fees of $90 a ton,
but they can also mine those mountains
of trash for valuable gasses and turn them into electricity.
That’s what R.G. Engineering Company of Webberville, Michigan is doing for
their clients.
If a landfill is designed properly, that is. Lined first with a heavy plastic to prevent seepage into the ground water, all those goodies stay put, waiting to be harvested. In particular, what Jon Rabitoy, president of RPG, is after is trapped methane.
We’re all familiar with methane. It’s
the gas we generate ourselves after a meal
of bad chili or cauliflower. We don’t generate enough to utilize other than to light as
a bachelor party prank, but a sealed landfill has plenty.
It works like this: gas wells are sunk from 30 to 90 feet in the landfill and a gentle vacuum sucks out the methane. It is then run through a battery of converters. Usually four are set up, with three always running while a fourth gets routine maintenance.
According to a confidential report from Rabitoy’s company, “Neenah/Menasha, Wisconsin developed a landfill over a 10-year period. The landfill was filled, capped and a collection system was installed 18 months ago. Today the landfill generates and flares 1,000 ft3/min of landfill methane gas, where the gas temperature is 96 degrees F and is delivered at 1 psig pressure to the flare.”
The electricity generated by this system is incredibly cheap, 2 cents a kilowatt hour created from the landfill gas which costs half a cent per kilowatt hour to recover.
The electricity is then sold for 5.5 cents a kilowatt hour, and the project’s net revenue is estimated at $475,146, with a simple payback for the project of 9.25 years.
Other systems can recoup the initial costs in less time, 5.1 years. Even more rapid payback can be derived from animal waste.
My brother was once part owner of a pig farm where the noxious waste was turned into methane to provide energy. They generated enough electricity on the farm to provide all their energy needs. A feed lot may produce many tons of animal waste. Anyone who’s lived within nostril range of one of those can testify to the noxiousness of that, but the electricity generated from that animal waste can recoup the costs of the installation in little over a year.
The electricity these systems generate is sold to the electric grid to supplement power generated by conventional plants. No wonder a landfill can turn into a profit for a municipality! They can collect at both ends.
What’s clear is that waste products from feed lots and city landfills can put a significant dent in our need for energy. I suspect that the Keweenaw bears are disappointed to no longer have easy pickings at our garbage dump, but if we go the way of Neenah/Menasha and other municipalities we’ll not only get some extra income, but we’ll utilize some of those infamous greenhouse gasses. Oh, and turn the stink to cash. You never knew the smell of money had an odor like that.
