Religious Bigotry President Obama has been roundly criticized for his apparent unwillingness to use the term “radical Islamic terrorism.” His critics seem to suggest that through the mere use of that terminology, the defeat of ISIS would be assured...

TC DDA: Focus On Your Mission What on earth is the Traverse City DDA thinking? Purchasing land around (not within) its TIF boundaries and then offering it at a discount to developers? That is not its mission. Sadly enough, it is already falling down on the job regarding what is its mission. Crosswalks are deteriorating all around downtown, trees aren’t trimmed, sidewalks are uneven. Why can’t the DDA do a better job of maintaining what it already has? And still no public restrooms downtown, despite all the tax dollars captured since 1997. What a joke...

European-Americans Are Boring “20 Fascinating People” in northern Michigan -- and every single one is European-American? Sorry, but this is journalistically incorrect. It’s easy for editors to assign and reporters to write stories about people who are already within their personal and professional networks. It’s harder to dig up stuff about people you don’t know and have never met. Harder is better...

Be Aware Of Lawsuit While most non-Indians were sleep walking, local Odawa leaders filed a lawsuit seeking to potentially have most of Emmet County and part of Charlevoix County declared within their reservation and thus under their jurisdiction. This assertion of jurisdiction is embedded in their recently constructed constitution as documentation of their intent...

More Parking Headaches I have another comment to make about downtown TC parking following Pat Sullivan’s recent article. My hubby and I parked in a handicap spot (with a meter) behind Mackinaw Brew Pub for lunch. The handicap spot happens to be 8-10 spaces away from the payment center. Now isn’t that interesting...

Demand Change At Women’s Resource Center Change is needed for the Women’s Resource Center for the Grand Traverse Area (WRCGT). As Patrick Sullivan pointed out in his article, former employees and supporters don’t like the direction WRCGT has taken. As former employees, we are downright terrified at the direction Juliette Schultz and Ralph Soffredine have led the organization...

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.
