Paging Doctor Dan: The doctor’s promise to repeal Obamacare reminds me of the frantic restaurant owner hurrying to install an exhaust fan after the kitchen burns down. He voted 51 times to replace the ACA law; a colossal waste of money and time. It’s here to stay and he has nothing to replace it.

Evolution Is Real Science: Breathtaking inanity. That was the term used by Judge John Jones III in his elegant evisceration of creationist arguments attempting to equate it to evolutionary theory in his landmark Kitzmiller vs. Dover Board of Education decision in 2005.

U.S. No Global Police: Steven Tuttle in the October 13 issue is correct: our military, under the leadership of the President (not the Congress) is charged with protecting the country, its citizens, and its borders. It is not charged with  performing military missions in other places in the world just because they have something we want (oil), or we don’t like their form of government, or we want to force them to live by the UN or our rules.

Graffiti: Art Or Vandalism?: I walk the [Grand Traverse] Commons frequently and sometimes I include the loop up to the cistern just to go and see how the art on the cistern has evolved. Granted there is the occasional gross image or word but generally there is a flurry of color.

NMEAC Snubbed: Northern Michigan Environmental Action Council (NMEAC) is the Grand Traverse region’s oldest grassroots environmental advocacy organization. Preserving the environment through citizen action and education is our mission.

Vote, Everyone: Election Day on November 4 is fast approaching, and now is the time to make a commitment to vote. You may be getting sick of the political ads on TV, but instead, be grateful that you live in a free country with open elections. Take the time to learn about the candidates by contacting your county parties and doing research.

Do Fluoride Research: Hydrofluorosilicic acid, H2SiF6, is a byproduct from the production of fertilizer. This liquid, not environmentally safe, is scrubbed from the chimney of the fertilizer plant, put into containers, and shipped. Now it is a ‘product’ added to the public drinking water.

Meet The Homeless: As someone who volunteers for a Traverse City organization that works with homeless people, I am appalled at what is happening at the meetings regarding the homeless shelter. The people fighting this shelter need to get to know some homeless families. They have the wrong idea about who the homeless are.

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.
